    Factors affecting adoption of IR-64 rice-variety in selected barangays of Munoz, Nueva Ecija
    (1989) Lava Prasad Upadhyay
    This study inferred the relationships of certain demographic, economic characteristics, communication media and support services related with the rate of adoption of IR-64 rice variety. One hundred and eighty farmers were interviewed. Twenty one percent of the farmers adopted IR-64 immediately after they have known about it. Fifty two percent planted the same variety only a year after they have heard about IR-64. The correlation test reflected that years of schooling, print media, farm demonstrations, seed chemical fertilizer and pesticides availability were sinificantly related with the rate of adoption of IR-64, whereas farming experience and land tenure were found negatively significant. Multiple regression analysis showed that years of schooling, land tenure, print media, and seed availability were significant predictors for rate of adoption. Mean years of schooling was seven years where mean farming experience was 21 years. Seventy four percent of the farmer respondents were amortizing owners. Majority of the farmers had no exposure to print media like agriculture publications, magazines, etc. due to non-availability of print media at the barangay level. Albeit, IR-64 seeds were available, chemical fertilizer and recommended pesticides for IR-64 were not available for majority of farmer respondents. Fifty percent of the farmers were not getting loans for IR-64 cultivation. The number one problem encountered by farmers relevant to IR-64 production was the high cost of farm input like chemical fertilizers, seeds, pesticides. Next to this problem was the non-availability of credit for IR-64 cultivation followed by susceptibility of the variety to diseases. The farmers suggested that government subsidy in the price of the farm inputs should be given to make production affordable. They also pointed out the need for government support to raise the selling price of their products (IR-64). To save the crop against the attack of insect pests and diseases, the farmer-respondents also cited the need to make timely and adequately available the required insecticides and pesticides.

    Factors associated with rice farming employment in two municipalities of Nueva Ecija, Philippines
    (1988) Md. Mustafizur Rahman
    The study was undertaken to investigate some personal and economic factors associated with family, hired, and total labor employment per farm in rice farming in the municipalities of Munoz and Guimba in the province of Nueva Ecija. The main purpose was to identify variables which are significantly associated with family labor, hired, and total labor employed per farm. It also aimed to find differences that may exist within municipality and between the two municipalities. The analysis was based on primary data collected through personal interviews with 200 farmer-respondents equally representing the two municipalities studied. The relationship between dependent and independent variables were determined by means of regression coefficients. Ordinary least-square regression was used to estimate the employment parameters in the total labor model. Family and hired labor were estimated by two-stage least squares (2 SLS). The functional form of the equation was assumed to be arithmetically linear. The study found that the differences of irrigation facility differentiated the input status of farmers in the production process and consequently the employment opportunity and pattern between these two municipalities. The municipality of Munoz had more employment in rice farming and had more irrigation facility than the municipality of Guimba. Regression analysis showed that the farms which increased their production inputs tended to increase the amount of labor (hird labor in particular) employed per farm. These production inputs were irrigation, seed, fertilizer, and insecticide. Other variables were either partially significant or not significant with family, hired, and total labor employment per farm.

    Training needs of agents of the Plant Protection Services Unit at the Department of Agricultural Extension in Thailand
    (1988) Sakda Sinives
    This study was undertaken primarily to identify the training needs of Plant Protection Service Unit (PPSU) agents in the Department of agricultural Extension of Thailand and to find out if this is associated with attitudes. A total of 155 respondents comprising of 25 chiefs and 130 agents from six regions of Thailand were selected using stratified random sampling. The data gathering device was a research developed questionnaire and interview schedule. Data were analyzed using descriptive statistics, chi-square test, Pearson's product moment correlation and t-test. The results showed that the chiefs and agents had mean ages of 45.56 and 35.85 years respectively. Both groups consisted mostly of married males. The chiefs had higher educational attainments than the agents. The chiefs and agents had length of service in their present position equal to 9.64 and 9.13 years, respectively. The PPSU agents had extensive trainings in plant protection but not on extension methods. Both PPSU chiefs and agents perceived that there was much need for trainings in these areas. There was no significiantdifference in the training needs as perceived by the PPSU agents and chiefs. This was true for both training areas in plant protection subject matters and in extension methods. The PPSU chiefs and agents had positive attitudes towards the training needs of PPSU agents. They agreed that the PPSU agents needed trainings in their line of work. The attitudes of the PPSU chiefs and agents in Thailand toward the PPSU agents' training needs were not significantly different. A significant relationship exists between the attitudes of the PPSU agents and their perceived training needs in plant protection subject matters and in extension strategies. In the case of the PPSU chiefs, a significant relationship exists between their attitude and perceived training needs of PPSU agents in plant protection subject matters. However, on extension strategies insignificant results were found. This implies that PPSU chiefs with higher levels of perceptions on the agents' training needs in plant protection matters also had higher attitude levels on the same. This is not true, though, in the case of the agents' training needs in extension strategies. The respondents suggested that subject matters to be offered for training are modern extension strategies on micro organism control on plant protection, horticulture vertebrates, and field crop needs. It should include field trips and the like. Regarding the extent of adoption, only 25 percent had continuously adopted the cropping pattern technology. Extent of adoption was significantly related with some of the independent variables like household size, net return, savings, sufficiency of credit, labor category and the availability of inputs. Some of the problems perceived by the respondents were: (1) limited sources of information, 2) low net return, 3) small saving, 4) high cost of labor and inputs. Respondents suggested that 1) the number of extension officials should be increased so that their services are available when needed and strengthen the applied communication program more effectively, 2) government should provide the inputs in affordable price by subsidizing he cost of inputs, and 3) the credit should be included in the technological package with reduced interest rate.
