Processing of Data/Analysis/Report Writing The data generated from the study were collated, analyzed, organized, and presented in this report. These results will be the basis for improving existing farming systems of the farmers particularly in the introduction of INM in their sweetpotato farms. The improvement will be based on the identified problems, farmers’ resources, and capabilities. Alternative improvement will be assessed by the farmers themselves through Participatory Research Approach (PRA) and Participatory Technology Development. RESEARCH FINDINGS Biophysical and socio-economic profile of the communities studies The following describes the biophysical and socio-economic profile of the towns and barangays which were the focus of the study. There were ten barangays considered: two each in San Marcelino and Botolan, Zambales; one each in Bamban, and Capas, and two each in Gerona, and Moncada in the province of Tarlac..
