rice production in most of asian countries has been increased more rapidly than population and this has been led to increase in supply and proportionately decrease in the real price of rice in world and domestic markets. furthermore, together with growth in production and national gross income of the country per-capita income has been increased and also demand for rice at national and internati...

This paper studies the structure of cost and production of rice using cross section data from rice farming in Guilan in 1997. A translog cost function is specified for this purpose and estimated, using Iterative Seemingly Unrelated Regressions for both the short and the long run where all factors are taken to be variables. The results of the study are as follows: 1. Neither in the short-run nor...

This study examined the adoption prospects and challenges of rice-cum-fish production technology among rice and fish farmers in selected States in southern Nigeria (Delta, Edo, Lagos and Ondo States). Using questionnaire, data was sought from 720 sampled rice and fish farmers in the selected States. The data were analysed using descriptive statistics, logit regression. Results showed that more ...

Productive efficiency for Chinese hybrid and conventional rice production is estimated using a dual stochastic frontier efficiency decomposition model. Results reveal significant differences in technical and allocative efficiency between conventional and hybrid rice production, and indicate significant regional efficiency differences in hybrid rice production, but not in conventional rice produ...

Risk and uncertainty have an important role in determining farmers' goals and their decision making. Risk affects optimal use of inputs and production efficiency. Using production inputs especially new inputs is one of the effective factors in production risk hence, it is necessary to obtain information about inputs use risk in order to find solution to risk management. For investigating effect...

efficiency in agricultural production is indicative of the efficiency level of farm households in their farming activities. farmers in developing countries do not make use of all the potential technological resources, thus making inefficient decisions in their agricultural activities. herein, technical efficiency in relation with the production of three types of rice crop (boro, aus and aman) w...

Climate in its spatial and temporal inconsistency is one of the chief causes for determining agricultural productivity in a region. Climatic impacts should be kept into mind while developing long term agricultural policies. This study aimed at investigating the change in rice production in Pakistan from 1989-2009 using the GIS techniques and the impacts of climate change on rice production. Pak...
