Cooked rice is a staple food for Koreans which provides more than 60% of daily required energy. In 1960's, Koreans ate 600 g-800 g of cooked rice per meal and the energy obtained from cooked rice was almost more than 80% of the daily intake of energy. However, as the economy of Korea improved, the major industry has been shifted from agriculture to various manufacturing industries and the expor...

This study investigated the technical and scale efficiencies in rice production by rice farmers in Ebonyi State Nigeria using the data envelopment analysis (DEA). Data was collected from a sample of 180 farmers using multi-stage sampling technique. Data were analysed using descriptive statistics and Data Envelopment Analysis (DAE) approach. The result showed that majority of the rice farmers we...

with the increasing world population and limitations on arable land, increasing the yield per unit is one of alternatives human food supply. greenhouse cultivation as one ways of increase the performance can arrive this purpose. but the energy restriction of another human challenges, so that increase the performance without considering energy consumption almost appears to be meaningless. due to...

I . The effect of fortification of rice with lysine and threonine (at levels of z g and I g/kg respectively) on the growth of preschool children was assessed in feeding trials at a residential orphanage and a village day-care centre. 2. In the first trial, the children at the orphanage were offered a diet based on rice, to provide the recommended allowances of protein and energy. For the childr...

Rice (Oryza sativa L.) is one of the most important crops in the world. It is essential to develop an efficient method to build the fingerprinting database of commercial hybrid rice cultivars and their parental lines in seed market for rapid and unambiguous cultivar identification and seed purity analysis as new similar cultivars increasing yearly. The objective of this investigation were to fi...

The aims of this study are to measure the technical efficiency (TE) of Cambodian household’s rice production and trying to determine its main influencing factors using the stochastic frontier production function. The study utilized primary data collected from 301 rice farmers in three selected districts of Battambang by structured questionnaires. The empirical results indicated the level of hou...
