Researchers Title Brief Description
Araceli J. Badar National Cooperative Testing for Rice – Rainfed Lowland Dry-seeded (continuing) The NCT-Rice is a collaborative project between PHILRICE and MMSU. This is an advance yield tests comprising of different promising rice entries from various institutional breeding programs. This is simultaneously conducted in several sites all over the country to find out their range of adaptability under varied agro-climatic conditions. Here, in MMSU, we evaluate rice varieties suitable for rainfed lowland ecosystem. It aimed in identifying rice genotypes that are high yielding, of good eating quality and show resistance to insect pests and diseases. Poor performers were being dropped out from the trial and were replaced with new entries for the next trial. The over-all performance is evaluated and used as basis in deciding national recommendations and release by the Philippine Seed Board
Araceli J. Badar, Ma. Concepcion B. Birginias and Marissa I. Atis Effect of Potassium & Phosphorus fertilizer on the growth, yield and storability of Ilocos white garlic variety (completed)

This project was conducted in 2 consecutive years. It aimed to determine the fertilizer management of Ilocos white garlic and evaluate its effect in storage. Specifically, to evaluate the level of potassium at different application dates; to determine the performance of Ilocos white garlic as affected by levels of phosphorus and split application of potassium; and the performance when added with organic fertilizer with those P and K treatments and asses the bulbs when stored in 6 months.

Results of the two year of evaluation showed that dates of application, levels of phosphorus and split application of potassium did not affect the agronomic performance of Ilocos white garlic. A significant difference was observed on the results across years, wherein the growth and yield performance of the garlic plants showed superiority in Year 2 than in Year 1. This difference was clearly attributed to the weather conditions during the evaluation period. The weather condition in Y2 was more conducive to garlic production than in Y1.

No significant weight losses and damaged clove/bulb of Ilocos white garlic applied with different levels of potassium at different application dates, levels of phosphorus and split application of phosphorus when stored for 6 months. Meanwhile, with the addition of organic fertilizer at the rate of 5.0 t ha-1 to different levels of phosphorus and split application of potassium, a 33% and 38.46% higher yield, was obtained respectively as compare to those without organic fertilizer. Longer and wider leaves, lesser incidence of purple blotch and tangle top, bigger bulb sizes were obtained from those with organic fertilizer compared to those without organic fertilizer.

Maria Concepcion B. Birginias, Menisa A. Antonio and Josefa L. Pugat Development of Propagation Management Technology for the Wild Vegetable on Alokon (Broussonetia luzonica) Alokon (Broussonetia luzonica) is a popular indigenous vegetable in the Ilocos Region as well as in Cagayan and Apayao. The inflorescences or the flowers and the tender young leaves are widely marketed to a price ranging from 200 pesos to 500 pesos during season. These are commonly used as one of the main ingredients to various native Ilocano dishes such as pinakbet, dinengdeng, and even steaks to improve textures and aroma. However, literature on alokon crop and the propagation management technology is still limiting and there is no known yet local variety identified in the Philippines. Since, one of the major constraints of alokon is the difficulty of root growth, the focus of this research is on the propagation method by stem cuttings of a mature branch determining the response of cuttings applied with different rooting hormones and used of different potting media, employing different cutting length, soaking time and different concentration of Hormex to enhance its domestication, propagation and establishment of duplicate mother trees of selected ‘varieties’ at MMSU. Use of Hormex as rooting hormone and RS+OF+DRH as potting media consistently had the most numbered of buds, number of leaves per bud, highest survival rate, longest root, and highest net income and ROI. Stems cut into 40cm produced the highest survival rate while stems soaked in 4hrs had the most number of buds. Use of 5ml/liter concentration of Hormex produced the most numbered of leaves and longest bud but were comparable to 10-25ml/ and highest survival rate was obtained when 10-25ml/liter concentration was used.
Charito Samsam, Joselito Rosario, Setgia Garma, and Roseller Ayson Phenological Assessment of Selected Indigenous Timber Species in Ilocos Norte

Seed shortage is oftentimes the limiting factors in scaling-up the rehabilitation of denuded areas. This is due to the unpredictable fruiting seasons of most trees and short viability of recalcitrant seeds. Hence, this study was conducted to provide information on the phenology of superior mother trees of selected indigenous timber species to develop seed calendar that could facilitate seed collection and planning of nursery operation and timely production of quantity planting stocks.

Results revealed that peak of flower bud inception of V. parviflora, D. dao, W. pubescens and A. thurifera starts after leaf flush during the first rain in May while flowering activity of S. supa and I. bijuga comes earlier during mid-summer. However, flowering activity of V. parviflora continuously occur towards the early dry months in January in synchronize with fruit development and maturation. Fruit development and maturation had the longest phenophase of 8-9 months in A. thurifera and W. pubescens, 3-4 months in V. parviflora, 4-5 months in I. bijuga and 2-3 months in D. dao and S. supa. Timing of flowering and fruiting remains unchanged in almost all the timber species. Thus, the ideal time of collecting seed or fruit of D. dao is August – September, V. parviflora is September- October, S. supa is May – June, I. bijuga is October-November, and A. thurifera is April – May.

Charito Samsam, Joselito Rosario, Setgia Garma, and Roseller Ayson Bon Jovi Orteza Evaluation And Selection Of Suitable Indigenous Timber Species In Different Site Conditions

The success of any reforestation or rehabilitation activity depends on the appropriate choice of species, adequate knowledge of potential species and their performance under a given site condition. Hence, this study was conducted to identify the most promising indigenous timber species (ITS) for the rehabilitation of denuded hilly areas in Ilocos Norte.

Based on the results, non-dipterocarp species such as V. parviflora, W. pubescens, I.bijuga, S. supa and D. dao are recommended for open and degraded areas. Dipterocarp species such as H. plagata, A. thurifera and S. guiso are also promising, however, these species require the provision of compatible species mixture to reduce direct exposure to sunlight and to improve the stem form especially during the early stage of growth.

Charito Samsam, Joselito Rosario, Setgia Garma, and Roseller Ayson Bon Jovi Orteza Fertilizer Management of Different Indigenous Timber Species Under Semi-Arid Hilly Area Condition

The hilly areas in the Ilocos have marked nutrient deficiencies because of inherent low nutrient fertility and due to improper management. Due to the insufficient supply of nutrients, plant growth is stunted and plants become vulnerable to environmental stress. Thus, it is necessary to integrate fertilizer management strategies to supplement nutrient demand for plant growth to restore the productive capacity of these areas.

Based on the results, it can be deduced that the application of 50g 14-14-14 + 300 g OF is sufficient to enhance the growth characteristics, biomass, vigor and survival rate of the newly planted ITS. Although the application of 70g 14-14-14 + OF enhanced the growth and vigor, this did not enhance the survival rate of the different ITS.

Alecsis G. Villarin, Jonathan R. Ramos and Leticia A. Lutap Development of Ecologically Based Pest Management Practices in Garlic

Ecological Pest Management (EPM) is an approach to increasing the strengths of natural systems to reinforce the natural processes of pest regulation and improve agricultural production. This is because the greater the diversity of natural enemy species, the lower the density of the pest population, and as diversity of natural enemy species decreases, pest population increases. However, specific pest problems can be addressed in part by adding specific plants to the farm system, or by building and maintaining habitat on the farm that attracts and retains beneficial insects and pollinators, or by a combination of both strategies. In addition to habitat around crop fields, within-field polycultures or intercropping systems show great promise in a balance agro eco system. Hence, MMSU is always committed to provide solutions to the problems of the garlic industry. With the erratic weather conditions in the various agro-ecological systems, this brought pest outbreaks in the past years. To identify correct management techniques and crop assemblages that sustain the performance of the ecosystem, this research conducted three components: First is, Habitat management through manipulation of the farm ecosystem, second, Habitat management through the use of appropriate cultural practices and third, Enhancing the activities of biological control method in the farm ecosystem through the use of trap crops/band rows.

Based on the results of the study, Pest incidence and infection of the garlic plants were highly influenced by crop spacing. Higher occurrences of purple blotch and cercospora leaf spot was noted on closer planting (15cm x 15cm) as compared to wider spacing of 20cm x 15cm and 20cm x 20cm.The used of trap crops and hedge rows like marigold and corn is encourage not only to suppress the attacked of destructive pest but to increasing crop quality, attract natural enemies and reduce pesticide use.

Calventas Luis Augustus G. Palafox Mary Cris H. Calpito Genetic Improvement for Bolinao Chicken through Conventional and Molecular Breeding Approaches

Bolinao native chicken is a unique genetic group in the Ilocos region which are predominant in the province of Pangasinan. However, this genetic group were found to be in small number. This may be attributed to indiscriminate breeding with exotic lines in different upgrading activities crossbreeding, replacement by commercial breeds or simply they are being neglected. Hence, conservation measures must be implemented, and these native chickens of have to be protected from extinction through intensive breeding programs, both at the species and population levels.

The project focuses the purification of the Bolinao Native Chicken. At present, the True-to-Type Bolinao chicken starts to lay eggs at about 24 weeks old. It can produce 60 eggs per year. The eggs laid weigh 41.35 grams on the average. Of the eggs produced, 48.19 % were fertile and 60.87% of the fertile eggs were able to hatch. To improve the current average performance of the Bolinao chicken, continuous breeding and selection is necessary.

Evangeline S. Galacgac, Criselda Balisacan Traditional weather forecasting methods in Ilocos Norte The study is about the weather forecasting methods that are traditionally used by Ilocano folks as bases in predicting the onset of the wet season, occurrence of rain and adverse weather conditions. Their common indicators have indeed scientific bases. These traditional methods (weatherlores) were validated in different towns of Ilocos Norte and were found to be weather related. These indicators were used in planning their day to day farming activities especially during the wet season.
