    The agricultural education outreach project in Aklan: Barangay Sibalew, Banga
    Bautista, Reynold R. (Division of Social Sciences, College of Arts and Sciences, University of the Philippines Visayas, 1992-07)
    This study uses the concept of agricultural extension as a catalyst of change for rural development. Suffice it to say, the objective of agricultural extension is to provide the rural people the appropriate information, technology and values to make them self-reliant in the context of their own environment. However, the realisation of this goal is dependent on the extent of acceptance and participation of the rural people themselves. In this study, the Aklan Agricultural College-Agricultural Education Outreach Project in Aklan is supposed to bring self- reliance among the farmers of barangay Sibalew, Bangs by effective transfer of appropriate technology. Based on the principles of extension service, it has been determined that the A.E.0.p project in Sibalew, particularly its economic and social services, has been instrumental in improving the productivity and income and broadly, the social and economic aspects or the farmers life. Needless to say, the A.E.0.P-introduced technologies have been embraced by the majority of farmers in the barangay--which exemplifies the effectiveness of the A.E.O.P project.

    Small farmers' adoption of rice combine harvesters in Binalbagan, Negros Occidental
    Bayona, Kate Ashley S.; Solano, Mirjana Antoinette (Division of Social Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2024-06)
    The use of Rice Combine Harvesters (RCH) is currently pushed as part of the country's mechanization program in agriculture. Much of the literature assessing the adoption of RCH only focuses on the tangible determinants of their adoption, but not the in-depth sociological lived experience of farmers following their adoption, including their nuanced rationalization amidst the process. This study investigated the RCH adoption among small farmers in Binalbagan, Negros Occidental, specifically delving into the (1) characteristics of farmers, (2) drivers of RCH adoption, (3) challenges faced during adoption, (4) nature of frequency and consistency of RCH use, and (5) adjustment strategies in using the RCH pursued through descriptive phenomenology and an in-depth interview of 12 participants through purposive sampling. Thematic analysis revealed that the small farmers belong to the early majority adopter category whose adoption is highly facilitated by membership in Irrigators’ Associations and lack of manual laborers. The regularity of their usage also depended on climate, laborers, topography, and farm systems and confronted issues with wastage, additional cost and labor, and field damage to RCH that was mitigated through mediating previous and current farm set ups and maintaining affirmative social relationships within the community. These findings depict the complexities in small fanners’ RCH adoption and the intricacies of their receptivity in each region calling for larger analysis of RCH adoption in the country to know its general status and underscores the need for the implementation and development of national policies like technology diffusion to be contextually sensitive and pro-farmers.

    Effects of Chromolaena odorata leaves as amendments to poultry manure and inorganic fertilizer to improve growth, yield, biomass accumulation and inorganic content of tomato (Lycopersicum esculentum)
    Balinas, Chona Mae D. (Division of Biological Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2012-04)
    Chromolaena odorata (a weed in the family Asteraceae) has been shown to enhance the buildup of organic matter in a fallow system in tropical soil. Therefore, the aim of this study was to to determine the effects of Chromolaena odorata leaves as an amendment to poultry manure and triple 14 inorganic fertilizer on the growth, yield, biomass accumulation and inorganic contents of Lycopersicum esculentum. The field experiment was conducted at Agsanayan Buenavista Guimaras where the weed has wide distribution. The leaves of C. odorata were air dried and composted using Berkeley method. The compost obtained was used as an amendment to either poultry manure and inorganic fertilizer and was tested on tomato for three months in RCBD. Obtained results proved that tested treatments with amendments of C. odorata were significantly higher in lengths of shoots and roots, flower and fruit yield, amount of biomass accumulated and inorganic contents of tomato than those with no amendments of C. odorata. Therefore, C. odorata is an efficient amendment to both organic and inorganic fertilizers. It was suggested that the weed should be utilized to serve as a green manure.
