Title: Testing of Re-adjustable Multiple-dibbler Ergonomic Tool (RaMdE Tool ™) Using Commercial Peat-based Growing Medium
Name: Engr. Raffy M. Espiritu & Dr. Luz C. Collado
Abstract:

A prototype unit of a re-adjustable multiple-dibbler ergonomic tool (RaMdE Tool) was tested for tray-based seedling production of high value crops. The performance of the prototype tool using commercial peat moss medium (Treatment 1) was compared with the recommended local soil potting medium (1 part decomposed manure+1.5 carbonized rice hull) as Treatment 2 (control) in 162-cells seedling trays.

The performance of RaMdE Tool in terms of effective dibbling time, dibbling quality, device efficiency and dibbling capacity was not significantly affected using either of the two kinds of medium for seedling trays. This finding supports a claim that this tool is applicable to home-made or commercial peat moss formulation for seedling tray medium.

Title: RESPONSE OF PECHAY, (Brassica rapa) TO ORGANIC FERTILIZER UNDER DMMMSU-NLUC CONDITION, LA UNION, PHILIPPINES
Name: ANGELITA J. PRADO and LILIA O. SAMPAGA
Abstract:

The response of B. rapa to organic fertilizers was tested using two organically produced composts: non-vermicompost (T1), vermicompost(T2), with the conventional urea as control(T0). Addition of Bio-N during the basal application was part of the organic inputs. Treatments were compared in 4 replicates. Each treatment was composed of 16 plants at a distance planting of 20cmx40cm between hills and rows respectively. Application of fertilizer was done basal and harvesting was conducted twice starting from 30 days and 34 days. With the three treatments compared, effect of fertilizer applied was measured in terms of plant height, leaf area length, weight of marketable leaves, weight of marketable plant, number of leaves per plant and the leaf area infestation. Consistent result, except for leaf area pest infestation showed that those plants applied with vermicompost manifested the highest mean. Nevertheless, insignificant differences existed (P>.05) on the effect of fertilizer used as tested through ANOVA. In conclusion, use of organic fertilizer is comparable with the use of urea in pechay production. With this findings, it is recommended to organic farmers and gardening enthusiasts that use of organic inputs is preferred due to its chemical-free and environment friendly attributes.

Title: Teacher’s Time Management and Student’s Academic Achievement in LPU College of Nursing: Basis for an Enhanced Classroom Management
Name: Ruben L. De Guzman Jr. RN MAN and Imelda A. Guy
Abstract:

Background: Today, the concept of time and its management is much more important than it was in the past. With the fast-faced world where technology plays an important role in knowledge and information dissemination, people, especially professionals are working harder and longer to achieve their goals as academicians. How people manage their time will determine for how successful they become in the various aspects of their career and life undertakings. Objectives: The study aimed to determine the teacher’s time management and student’s academic achievement of the College of Nursing. Specifically, the study sought to determine the time management used by nursing university professors using the areas of time management evaluation as to a) allocated time; b) engaged time; c) individual engaged time; c) teacher use of time and d) academic learning time; to present the academic achievement of nursing students in terms of their GWA in the nursing professional subjects; to test relationship of the nursing University professors’ time management styles and the academic achievement of nursing students and to propose program to enhance classroom management of nursing university professors.
Method: The study employed the descriptive-correlational design. As applied in this study, initially, description was made to discover the present time management time of the university professors. On a deeper perspective, the academic achievement of nursing students in terms of their general weighted average in professional subjects was also described. Using the purposive non-probability sampling technique, the participants of the study constituted the full-time nursing faculty members during the first semester of Semestral Year (S.Y.) 2011- 2012. For the purpose of getting the general opinion of the members of the faculty in the College of Nursing all of the 85 faculty members were used as participants of the study. Respondents were also 160 second year nursing students presently enrolled in their professional subjects, who constituted the total student population or 100%. The researcher adopted the instrument used in a research done by Locsin et al 2001 where he conducted a research in the same area. Modifications were done with the questionnaire with the help of experts in the validation of the instrument. To facilitate the analysis of the study, the descriptive analysis and inferential statistics were applied.
Findings: The performances of the nursing university professors are contributory to their ability to direct and control students’ learning activities. Nursing students perform fairly in their professional subjects despite of satisfactory time management styles of their professors. Engaged time is a significant predictor of the students’ academic achievement. Conclusions: Nursing University professors can manage their time well in the classroom. They use the time allotted for a subject to engage students in the lessons and meet learning outcomes. Engaged time highly influences the passing rate of the nursing students in their professional subjects.

Name: Rosenio c. Silvestre, Fe M. Camalig and Juliana Q. Silvestre
Abstract:

This study identified the different ectoparasite and endoparasite species of carabao in Region I; determined the seasonal prevalence of ecto and endoparasites of carabao in Region I per province and per species; and determined the seasonal degree of endoparasite infection of carabao in Region I.
Purposive sampling technique was used to identify the sampling sites. A total of 1,120 carabaos from the five provinces of Region I were randomly selected for the collection of ectoparasites and fecal samples. The parasites were identified based on their physical characteristics. The fecal samples were subjected to Modified McMaster and Modified Stoll’s Technique of fecalysis. Data were analyzed using frequency counts and percentages.
Nine ectoparasite species affect carabao in Region I. They were the Boophilus, Culex, Haematopinus, Lyperosia, Musca, Sarcophaga, Simulium, Stomoxys, and Tabanus species. Ectoparasites were more prevalent during the rainy season. Majority of the carabaos in all the provinces of Region I were affected with ectoparasites regardless of species with Lyperosia and Simulium being the most prevalent species..
Eight endoparasite species affect carabao in Region I. They were the Amphistome, Eurytrema, Fasciola, Monieza, Strongyle type, Strongyloides, Toxocara and Trichuris species. Endoparasites were more prevalent during rainy season and Strongyle type were the most prevalent species during both seasons. Degree of endoparasitic infection of carabao in |Region I was greater during the rainy season.

Title: Marcotted Pummelo (Citrus maxima (Burm.) Merr.) Species Treated with Different Concentrations of Commercial Alpha Naphthalene Acetic Acid (ANAA)
Name: Libunao, Virgilio M., Ancheta, Lucrecia A. and Analyn V. Sagun
Abstract:

Pummelo is a perennial plant belonging to family Rutaceae, scientifically known as Citrus maxima (Burm.) Merr. and locally known as lukban or suha. Marcotting is the most common type of layerage in nurseries around the Philippines. It is employed to produce a new crop of young proportioned foliage plants from old ones that have too much stem or grown too tall and lanky. Applying root promoting substances, such as ANAA, during marcotting is beneficial. Nurserymen and pummelo growers are still looking for an alternative approach or technique to reduce the duration and produce high quality planting materials. The study on marcotted pummelo species (V1- ‘Magallanes’, V2- ‘Siamese’, V3- ‘Red Chandler’) treated with different concentrations of commercial Alpha Naphthalene Acetic Acid (ANAA) C0 – No ANAA; C1- ¼ concentration (25% ANAA + 75% distilled water); C2- ½ concentration (50% ANAA + 50% distilled water); C3- ¾ concentration, (75% ANAA + 25% distilled water); C4- full concentration of commercial ANAA (100% ANAA) was conducted 1) to determine the performance of marcotted pummelo species as influenced by different concentrations of commercial ANAA 2) To determine the best concentration of commercial ANAA on marcotted pummelo; and 3) To determine the interaction of pummelo species and different concentrations of commercial ANAA on marcotted pummelo. This was conducted at the High Value Citrus nursery of the Don Mariano Marcos Memorial State University employing the Randomized Complete Block Design Factorial (RCBD Factorial) in three blocks. Results revealed that marcotted Magallanes and Siamese significantly formed earliest to callus and earliest to initiate roots than marcotted ‘Red Chandler’. Marcotted pummelo species treated with full, ¾ and ½ strength concentration of commercial ANAA formed and initiated the earliest callus and roots. A significant interaction was observed among the treatment combinations on root initiation. Marcotted ‘Magallanes’ treated with full, ¾ and ½ concentrations of commercial ANAA significantly initiated earliest roots. ‘Siamese’ and ‘Red Chandler’ significantly produced more roots. ‘Siamese’ significantly gave higher survival rate of potted marcots at 45 days after potting (DAP) than ‘Magallanes’ and ‘Red Chandler’. No significant differences was observed on the percentage success of marcottage and 90 days after marcotting (DAM) and survival rate at 45 DAP as affected by different concentrations of commercial ANAA.

Title: Life Satisfaction of Adults in Retirement Age
Name: Dr. Myra C. Britiller; Joezel A. Pesigan;Mark Joseph B. Pillado;Nikki Rose M. Portuguese Jobelle Principe
Abstract:

Background: Life satisfaction is an outlook toward one’s own life; it may be a reflection of feelings about the past, present and future. It is an overall assessment of feelings and attitudes about one’s life at particular point in time ranging from negative to positive. Life satisfaction of older adults greatly depends on the condition of their health, emotion and sexuality along with their previous occupation and although age related changes are inevitable, most problems affecting older adults are influenced by many internal and external risk factors

Objectives: The study aimed to assess the level of life satisfaction of adults in retirement age. It specifically identified the profile of the respondents such as gender, civil status, religion, economic status, and their life satisfaction in terms of occupation, health, emotion and sexuality and at the same time as, the relationship between the respondent’s profile and their level of satisfaction was determined. Also, the study proposed a plan of action for adults in retirement age to improve their quality of life, develop a better understanding with regards to the physical, physiologic, emotional, and personal changes they have been going through and enhance their self-esteem and self-worth.

Method: The study used descriptive research which focused on the present condition. The subjects of the study were older adults from selected barangays of Batangas province. The study employed the use of purposive or judgemental sampling. The researchers adapted a tool called Utian Quality Life Scale (UQOL) which was developed with a series of objectives to capture influences on sense of well-being from a variety of domains that would be empirically determined.

Findings: Adults in retirement age who are female, married, Roman Catholic and have an average monthly income from previous occupation are most likely to be moderately satisfied with their life. Adults in retirement age are satisfied with their life if they can control things which are important to them, if they have a stimulating sexual life, contented in their romantic life and if they can continue to set new professional goals for themselves. Civil status and economic status are significant factors in one’s life satisfaction.

Name: Dr. Leonila M. Adarlo, RN; Jenifer E. Cantre; Jacquiline R. Capuno; Joyscebelle E. Casa; Leah B. Casapao
Abstract:

Background: Childhood care practices or understanding and love for the child ages 1-3 is shown by giving all the freedom that can safely use in an environment. The child was dependent upon other for the satisfaction and by giving guidance in the changing social situation in which he feels to be focal point (Buenviaje, et al 2008). Identifying the importance of health care practices of parents among children is an important issue in counseling parents and development of appropriate plan for child care

Objectives: The researchers involved in this study identified the alternative health care practices of parents among children. This study was conducted to: identify the health practices of parents regarding child care in terms of dietary consumption, management of illness and behavioral modalities; determine the effectiveness of health care practices given by parents among toddlers in term of social, psychological and financial; identify actions that may be proposed to improve the health care practices of parents among children.

Method: The researchers used the descriptive method of research. Descriptive research tends to observe, describe, and document aspects of a situation as it naturally occurs. The subjects of the study were the fifty-nine(59) respondents from selected barangays in Batangas such as Sampaga(20), Saimsim(23), Calicanto(10) and San Teodoro(6). The main instrument that the researchers will use in data gathering with regard to the respondents is the questionnaire. The questionnaire was a self-made from the collaboration of ideas of the researchers and other experts. The data gathered from the questionnaires were tallied, tabulated, analyzed and encoded using the SPSSv.18.

Findings: The respondents sometimes practice the promotive and preventive measures in terms of dietary consumption, management of illness and behavioral modalities. The respondents identified effective health care practices done among toddlers only sometimes. Mothers perceived that their children know and were able to seek medical check-up; take medications properly and performed hand washing every time they touch dirty objects as one of the identified health care practices.

Title: Growth and Yield of Selected Vegetables Sprayed with Mature Coconut Water
Name: Genaro D. Omo
Abstract:

Most soils planted with vegetables nowadays have limited or deficient nutrients resulting to stunted growth and low yield. The application of inorganic fertilizer can provide some of the nutrients needed by the plants while foliar feeding is an effective method too for supplementing the micronutrient deficiencies. The coconut water has the potential as a growth enhancer and yield booster because it is rich with different nutrients, phytohormones, enzymes, and minerals. Moreover, it is locally available, free and abundant in the public market.

Hence, the study was conducted 1) to evaluate the growth and yield of selected vegetables sprayed with different concentrations of coconut water, 2) to identify the most effective concentration of mature coconut water, and 3) to determine the cost and return analysis.

The vegetables used in the study were the finger pepper, tomato, bittergourd, squash and bottlegourd and the treatments are as follows: 0 fertilizer + 0 coconut water (Control); Sprayed with 100% Concentration of Mature Coconut Water; Applied with 100% Recommended Rate (RR) Inorganic Fertilizer; Applied with 75% RR Inorganic Fertilizer + Sprayed with 25% Concentration of Mature Coconut Water; Applied with 75% RR Inorganic Fertilizer + Sprayed with 50% Concentration of Mature Coconut Water; Applied with 75% RR Inorganic Fertilizer + Sprayed with 75% Concentration of Mature Coconut Water; Applied with 75% RR Inorganic Fertilizer + Sprayed with 100% Concentration of Mature Coconut Water.

All the vegetables (finger pepper, tomato, bittergourd and squash) applied with 75% RR inorganic fertilizer and sprayed with 50% concentration of mature coconut water produced the highest fruit yield, highest value of fruit yield, highest value of fruit yield increased over the control, and highest benefit cost ratio (BCR). Similarly, the bottlegourd plants applied with the same amount of inorganic fertilizer but sprayed with higher concentration of mature coconut water (75%) also produced the highest yield, highest value of fruit yield, highest value of fruit yield increase and BCR too.

Title: Growth and Yield of Banana var. Lakatan as Influenced by Azospirillum spp. Inoculation and Vermicompost
Name: Emilia B. Abalos and Lilia O. Sampaga
Abstract:

Bio-organic fertilizers such as Azospirillum spp. inoculation and use of vermicompost are low-cost and environment-friendly. Azospirillum spp. inoculation has been recommended for rice and corn. Being effective on non-legumes, it is worthwhile to try these also on bananas.

Two studies were conducted to determine the effects of bio-organic fertilizers (Azospirillum spp. and Vermicompost) on the growth and yield of outpotted tissue cultured banana seedlings under nursery condition and at field outplanting.

Results revealed that Ammonium Sulfate supplement at 4tbsp/16li water increased the number of leaves on the 1st-4wks but no subsequent significant effect was noted onwards. Ammonium Sulfate supplement increased the leaf area of seedlings at 2 months after planting. Plant height, length of leaves, number of leaves and number and length of roots were not significantly increased.

Vermicompost as potting media either at 50% or 100% significantly increased height, number, area and length of leaves as well as the number of roots of banana seedlings. Azospirillum sp.3 (Vital N) inoculation produced taller plants, more number of leaves, wider leaf area and more number of roots than those inoculated with Azospirillum sp.1 and 2 (Bio-N) for rice and corn but longer roots were obtained from Bio-N inoculated seedlings.

The second phase was further conducted to determine the residual effects of bio-organic fertilizer (Azospirillum spp. and Vermicompost) on field planting of outpotted tissue cultured seedlings previously applied with the said bio-organic fertilizers.

The experiment was laid out in Split Plot Design. Results revealed that growth in terms of girth (cm) of the pseudostem at shooting, number of leaves at 6 months after planting (MAP), at shooting and at harvest, plant height at 7mos after planting, number of days of from planting to shooting, number of days to shooting to harvest, number of days from planting to harvesting were comparable either with or without addition of bio-organic fertilizer. These growth parameters of banana were likewise not significantly different among the different sub-treatments. Yield in terms of length of peduncle (cm), length of fingers (cm), diameter of finger (cm), number of hand per bunch, number of fingers per hand, weight of middle hand, total number of fingers/bunch were comparable regardless of Azospirillum spp. used. Likewise, application of Vermicompost at 1-2 kg/plt. + 50% SLRR are not significantly different to the application of 100% SLRR using chemical fertilizers.

Yield of 14.78-14.55 kg/plt was obtained with and without additional Bio-organic fertilizer while Azospirillum spp. inoculation produced 12.88-15.59kg while Vermicompost produced 14.09-15.09kg/plt respectively while plants applied with 100% SLRR using Urea obtained 15.08/plt.

Name: Leonora E. Ngilangil, Samuel O. Olivar and Ma. Liezel A. Ballesil
Abstract:

Climate change adaptation is crucial in highly vulnerable areas. In this study, farmers awareness and knowledge on climate change concepts and adaptation strategies were determined as well as the problems and issues that hinders their adoption. Selected municipalities in northern region were chosen as study sites where a total of 799 farmers were taken as respondents . The farmer- respondents were selected randomly from active members of farmers association and cooperatives. A structured questionnaire, and focus group discussion were conducted to determine their awareness on climate change and to solicit their adaptive responses. The farmer-respondents in the region are highly aware on climate change concepts .They believed that crop production is at great risk during extreme weather events but not the human activities increasing greenhouse emissions. Of the 17 adaptation strategies enumerated, fifteen are oftenly adopted except for rain water harvesting, drip irrigation and livestock management which were found sometimes adopted. Adaptation measures being expensive, laborious and highly technical were found to be the issues and problems that hinder the adoption of these adaptive strategies. The Local Government Units should provide the infrastructure to the farmers to assist them adapt to climate change .

Title: EFFICACY TRIAL Of LIMA BEAN (Phaseolus lunatus) OINTMENT AGAINST DOG MANGE
Name: Nida B. Tabije, Gregory B. Viste, Fe M. Camalig and Gemmalyn Montero
Abstract:

This study was conducted to: (a) identify the species of mites affected by Lima bean ointment; (b) determine the efficacy of Lima bean ointment against mange in dogs; and (c) determine the most effective concentration of Lima bean ointment against mange in dogs.

Twenty four dogs positive of mange regardless of sex and age were used in the study. They were distributed into four treatments and replicated thrice with two dogs per replicate following the Duncan’s Multiple Range Test (DMRT). Dogs were also classified based on the severity of lesions. Skin scraping was conducted before the application of the different treatments to determine the number and species of mites present. Post-treatment mite count was done on each dog using the same site from the pre-treatment mite count. Extract from fresh Lima bean leaves were used in making the ointment.

The ointment was applied to the experimental animals twice a week for eight weeks using the different preparations such as the following: T0 – Plain Ointment, T1 – 20% Lima bean ointment, T2 – 25% Lima bean ointment and T3 – 30% Lima bean ointment

The gathered data were tabulated using means and percentages. Analysis of Variance (ANOVA) and t-Test were used to determine differences among the treatments.

Results showed that Lima bean ointment is effective against Sarcoptes and Demodex species of mites in dogs. Lima bean ointment is highly effective against mange in dogs with 97.76% efficacy for T1 and T2 and 100% efficacy for T3. Twenty (20%), twenty five (25%), and thirty (30%) percent concentrations of Lima bean ointment were highly effective against mange in dogs.

Title: Effect of Bio-N, Mycovam, Vermicompost and theirCombination on the Growth and Yield of Banana
Name: Emilia B. Abalos and Lilia O. Sampaga
Abstract:

Tissue cultured bananas need to be outpotted first in the nursery to improve the quality of seedlings before field planting (outplanting). The use of Bio-N and Mycovam as inoculants and the use of vermicompost in the potting medium were evaluated as to the seedling survival and growth (shoot and roots). Results showed that the percentage survival of the seedlings inoculated with Bio-N, Mycovam and in 50% Vermicompost + 50% ordinary garden soil (OGS) were comparable with seedlings applied with starter solution of 4tbsp/16li water. Tallest seedlings with longest and most number of roots however were obtained in seedlings at 50% Vermicompost and the combined inoculation singly with either Bio-N or Mycovam. Longest and widest leaves were obtained from seedlings at 50% Vermicompost.

Performance of these seedlings was further evaluated under field conditions. Results showed that outplanted banana have better growth and yield performance with additional bio-organic fertilizer than without additional bio-organic fertilizer. Bio-N, Mycovam, Bio-N + Mycovam and Vermicompost used as supplement to 50% of the recommended rate (RR) of 304g urea/plant have comparable effects on the growth and yield of banana similar to the application of the full recommended rate

Title: DETASSELING AND RATE OF SEEDING OF YOUNG COB CORN INTERCROPPED WITH OKRA DURING WET SEASON
Name: Velma T. Mañgaser
Abstract:

Young cob corn is a very promising crop however; availability of information on production management is limited. Hence, a study on detasseling and at different rates of seeding (3, 4, 5 seeds/hill) intercropped with okra was conducted employing the RCB factorial design with three blocks. The study was conducted at the experimental farm of DMMMSU-NLUC, Bacnotan, La Union.

Based on the results of the study, the highest yield was obtained from detasseled young corn at the highest rate of seeding (5 seeds/hill). A significant reduction in yield existed per unit decrease on rate of seeding. Moreover, the study failed to show any significant differences on the yield performance of okra intercropped to young corn.

However, a substantial yield advantage was obtained in young corn-okra intercropping scheme. Detasseled young corn planted at 5 seeds/hill registered the highest return on total expenses (573.93%) and benefit cost ratio of 5.89% and LER of “1.03” which suggest that is worthwhile investing in young corn-okra intercropping scheme production.

Title: COLLECTION AND EVALUATION OF VARIOUS HIGH - VALUE CITRUS SPECIES UNDER DMMMSU CONDITION
Name: Libunao, Virgilio M. and Analyn V. Sagun
Abstract:

Citrus fruits are known for their wholesome and health-giving properties, having high Vitamin C and essential minerals content. It is a common belief that high value citrus can only be grown in semi-temperate areas, however, many of such species are being grown in some of the backyards of the populace in Region I. The terrain and climate of the region is considered very favorable for some of the high value citrus species. In spite of the damage being brought by some pests and diseases to citrus trees in the country, citrus growing still remains a profitable industry. In 1997, the Bureau of Agricultural Statistics (BAS) reported that Philippine citrus industry recorded a production of 151,000 metric tons valued at PhP 1,468,000.00 from 29,200 hectares harvest area. Hence, citrus fruits are considered of high commercial value.

The popularization and expansion of local High Value Citrus industry can contribute to the conversion of denuded mountains/hills into economically productive and environmentally sound area.

This study was conducted at the High Value Citrus Project of the Don Mariano Marcos Memorial Sate University to collect and evaluate various high value citrus species from within and outside of Region I and to identify the most productive high value citrus for Region I.

Among the 19 species collected there were only 10 species that are on its fruit bearing stage. Results revealed that oranges across years of fruiting showed that year 2008 produced the highest yield with a mean of 82.53 kg/tree and Perante orange (Citrus sinensis (L.) Osb.) obtained the highest percentage survival of 91.11%.On the mean yield of pummelo across years, highest yield was obtained in 2010 with 162.31 kg/tree. At present, the pummelo trees had reached its optimum development stage to bear fruits. Red chandler (Citrus maxima (Burm.) Merr.), recorded the highest percentage survival of 96.67%. Mandarin, in its fourth year (2008) of fruiting reached its highest production with 207.43 kg/tree. King mandarin (Citrus nobilis Lour.) maintained a 100% survival across years. Perante orange (Citrus sinensis (L.) Osb.), Red chandler (Citrus maxima (Burm.) Merr.), Siamese pummelo (Citrus maxima (Burm.) Merr.), Magallanes (Citrus maxima (Burm.) Merr.), and King Mandarin (Citrus nobilis Lour.) gave the best performance as to yield and survival and are recommended for planting. On the economic analysis, pummelo species (Magallanes (Citrus maxima (Burm.) Merr.), Red chandler (Citrus maxima (Burm.) Merr.), Siamese (Citrus maxima (Burm.) Merr.), gave the highest net return. All other citrus species had positive net return.
