The study was undertaken to describe the morphology and medicinal uses of some weed plants in Bukidnon. Specifically, it aimed to describe the morphological structures of the medicinal weed plants; identify some herbal weed plants which have medicinal and other economic uses; and to produce a guide or handbook of the herbal weed plants for instructional purposes. Three study sites were established on the bases of locations which include municipalities of Maramag, Pangantucan and Valencia, Bukidnon identified as study sites 1, 2 and 3, respectively. Each of the specified location under study has two main stations. In each identified station, field collections of herbal weed plants were conducted and identified station, field collections of herbal weed plants were conducted and studied by alpha taxonomy in an estimated 1,000 m farm lot. Results of the study revealed sixty-one (61) species in twenty-four (24) families of herbal weeds in all study sites and two (2) species were unidentified. The production of instructional material in book form was designed as an output of the research investigation which could be used for classroom purposes.

The study focused on specific biophysical and socio-economic watershed characterization viz., land use mapping, and survey of indigenous soil and water conservation practices and training needs assessment for capability building of the farmer occupants as partners in the rehabilitation and protection of the CMU catchment. Surveying work to gather technical data for mapping was done including timber inventory and other related field observation and documentation. Household level data gathering was conducted through interviews and small group discussions with key informants. The detailed land use map produced exhibited seven (7) different land uses – typical of other bigger watersheds in the country. Natural forest patches dominated the area (25.64%) along steep and moderate slopes, while cultivated farm lands spread over moderate and gentle slopes covering 19.26% and are highly erodible. Plantation forests cover 16.10% while open areas and grasslands occupy 9.67% of the entire area. The managed pasture lands comprising 12.96% lies along flat and gentle slopes and less prone to erosion, so with the coconut and durian plantation area (8.16%) which is similarly situated. Agroforestry areas (8.21%) are situated along moderate and flat areas. Based on the data gathered, few of the farmer occupants have knowledge n watershed (3.8%) and only those that attended college, while 17.72% have indigenous knowledge in soil and water conservation and have practiced them. These include contour farming (12.66%); tree planting along steep slopes and boundary lines (17.72%); and “alley-alley” (2%). Twenty-nine or 36.71% participated in the FRDP program on mixed planting of trees and corn.

This study was conducted to develop in vitro culture techniques on Dioscorea alata l. (ubi) and to evaluate the greenhouse performance of their in vitro derived plantlets. Young node explants of D. alata were collected, surface sterilized, inoculated in Murashige and Skoog (MS) culture medium added with various concentrations of naphthalene acetic acid (NAA) and benzyl adenine (BA). The various treatments were as follows: T1
(MS + 0.5 mg/l NAA + 0.5/l BA); T3
(MS + 0.5 mg/l NAA + 1.0 mg/l NAA + 1.0mg/l BA); T4
(MS + 1.0 mg/l NAA + 0.5 mg/l BA) and T5
(MS + 1.0 mg/l NAA + 1.0 mg/l BA). All the node explants in various treatments developed compact calli. Except for T4
with low percentage survival, most of the node explants in the various treatments survived while in culture. Formation of plantlets were observed in all treatments. The plantlets were later transferred to various potting media in the greenhouse: pure coir dust; garden soil + carbonized rice hull; pure garden soil; garden soil + sawdust. Those plantlets in pure coir dust exhibited 100% survival, indicating its suitability as a potting medium. When the plantlets were repotted to another medium, S2
(rice hull + garden soil + Agrofer), there was 100% survival. The harvested tuberous roots were later planted in G2
(garden soil + Agrofer + complete fertilizer) which showed 100% survival indicating it was another suitable potting medium for D. alata under greenhouse condition.

The study was conducted to analyze the supply and demand structure for milk and milk products in the Philippines. More specifically, it aimed to determine the supply elasticities of raw milk and the demand elasticities for six types of processed milk products. Government policies and programs affecting the production, marketing and consumption of milk were also reviewed. Due to data limitation, pooled regional and time series data of the NDA-assisted dairy projects were used to estimate the supply parameters. On the other hand, cross-section data gathered in major dairy areas such as Cebu, Northern and Southern Mindanao, Southern Tagalog (CALABARZON) and Central Luzon and major demand centers like Metro Manila, Cebu, Davao and Cagayan de Oro City were used in estimating the demand. Three functional forms were tested in the multiple regression analysis, namely: linear, semi-log, and the double log using the ordinary least squares (OLS) estimation technique. The double log was chosen for giving the best results. Despite some inefficiencies and weak government programs and policies, the study revealed that great potentials are awaiting the local dairy industry. The supply of raw milk responded to price and other shifters. Given the right government policy environment, the dairy farmers would be willing to increase milk production in response to price and other incentives, and reduce the country’s dependence on milk imports. Implied in the supply expansion is the improvement of the nutritional status of the Filipinos. High demand for quality fresh milk was found among milk consumers especially in Metro Manila and other areas. The estimated demand equations for most of the dairy products highlighted the significant effects of price and income on milk consumption. Furthermore, educational attainment, household size, awareness of the nutritive value of milk and consumer preferences were also found to explain the consumption behavior for some milk forms. Strengthening government programs and implementation of favorable policy measures are expected to lead to a sustainable dairy industry.

A survey was conducted to measure performance of the Faciolosis control extionsion program based on five indicators: change in knowledge level about Fasciolosis, change in farm practices over three cropping seasons, perceived consequence of adoption, preferred extension media and the extent to which Fasciolosis control strategies will be continued at village level. Findings how a marked increase in knowledge level about Fasciolosis and farmers adopted two Faxiolosis control practices on a trial basis: preventing animals from grazing and drinking on rice fields, shallow creeks and irrigation canals and deworming their animals using drugs. They perceived that liverfluke-free animals worked faster, commanded higher price and provided more income to the family than sick animals do. They considered that the program has increased the size, weight and draught power of their animals. Farmers preferred seminar-workshops and meetings with the CMU-ACIAR and the Department of Agriculture/LGU as the agencies that helped them most regarding Fasciolosis. They most likely will continue to use drugs as well prevent their animals from grazing on newly harvested fields in order to control Fasciolosis in their village. in general findings of the study imply some promising indicators which may contribute to economic efficiency and sustainability of the program at village level.

This paper attempts to evaluate the existing farming system in the corn-based agroecosystem of the Manupali watershed in lantapan, Bukidnon, Philippines. It determines the productivity and profitability by elevation and corn varieties. It also identifies the major constraints in the farming system faced by the farm household. The findings indicate that there is no significant difference in yield for OPV and hybrid corn across elevation. Both full cost and cash cost estimates revealed a higher profitability rate for low elevated farms than medium and high elevated farms.
