Profit Inefficiency among Hybrid Rice Farmers in Central Vietnam

Research on hybrid rice in Indonesia was initiated in 1983, in collaboration with the International Rice Research Institute. Since 2000 private sector had indicated their interest in hybrid rice seed business. Planted area of hybrid rice in Indonesia was still relatively small of about 658 thousand hectares or about 5.0 percent of the total rice planted area of 13.2 million hectares in 2013. This study was aimed to analyze farmers’ responses and preferences to the development of hybrid rice in East Java, one of the rice production center in Indonesia. Contingent valuation method (CVM) to analyze farmers’ Willingness to Accept (WTA) and Willingness to Pay (WTP) with respect to various factors was then exercised to evaluate constraints and prospect of the future of hybrid rice development in Indonesia. The outputs of this study showed that farmers’ preferences to hybrid rice based on its taste was positive, especially to the newly introduced hybrid rice variety “Hipa Jatim”, when compared with the previous hybrid varieties, such as Maro and Rokan. WTA and WTP also showed significant farmers’ interests to the hybrid variety, due to higher yield and its better taste, similar to that of popular inbred rice. Farmers’ WTAs of hybrid rice was significantly influenced by the productivity, response to pests and deseases, and the total cost of production, while consummers’ WTPs of hybrid rice was significantly influened by the quality of milled rice.

The study was carried out to examine the effect of agricultural transformation on the beneficiary’s productivity and poverty of rice farmers in Kano State Nigeria. A multi-stage sampling method was employed to select 571 respondents for the study. Data were collected through structured questionnaires on respondent’s income, input and output quantities as well as their expenditures. Data were analysis using descriptive statistics, Foster-Greer-Thorbecke (FGT), Propensity score matching and LATE model. Results from the study shows that respondents productivity revealed a significant difference of about 127 kg/ha in rice productivity between participants and non-participants. Also, the LATE estimates revealed an average treatment effect ATE0 of about 222.98kg/ha. Furthermore, the project had a significant effect N11, 321.4 on the participant’s consumption expenditure than the non-participants N9980.60. Moreover, participants were, able to increase their household total expenditures by N34780 per annum. Fluctuations of input/output prices insect pests and inadequate extension visits were all the major constraints faced by the farmers. It was recommended that farmers’ information and sensitization system should be overhauled and improved. Also, attention should be given to well organize extension visits for the farmers from stake holders

Boro Rice

Five phosphorus rates (0, 5, 10, 20 and 30 kg P/ha) were tested with four rice genotypes in Boro (BRRI dhan36, BRRI dhan45, EH1 and EH2) and T. Aman (BRRI dhan30, BRRI dhan49, EH1 and EH2) season. Phosphorus rates did not influence grain yield irrespective of varieties in T. Aman season while in Boro season P response was observed among the P rates. Application of P @ 10 kg/ha significantly increased the grain yield. But when P was applied @ 20 and 30 kg P/ha, the grain yield difference was not significant. The optimum and economic rate of P for T. Aman was 20 kg P/ha but in Boro rice the optimum and economic doses of P were 22 and 30 kg/ha, respectively. Hybrid entries (EH1 and EH2) used P more efficiently than inbred varieties. A negative P balance was observed up to 10 kg P/ha.
