A socio-economic study was carried out in two rice production environments (Gazipur and Tangail) to assess the comparative advantages of using urea super granule (USG) over prilled urea (PU) in modern rice production and to examine the differences in producers’ technical efficiency between USG user and nonuser in crop management. Stochastic frontier production model was employed to examine the ...

Rice has fed more people than any other crop has for thousands of years. The ancient Indian name for rice, Dhanya, means “sustenance for the human race.” Especially in much of Asia, life without rice has been unthinkable. Rice feeds more than half of the world population, but most rice is consumed within 10 miles of where it is produced. Rice is the 2nd largest crop in planting acreage after wh...

There have been many previous studies of technical inefficiency in rice production in the Philippines, but none has focused simultaneously on production risk and technical inefficiency at the farm level. In this study, we analyse technical inefficiency in a rainfed lowland rice environment in Central Luzon using a stochastic frontier production function with a heteroskedastic error structure.

To meet the growing food demand of Bangladesh requires efficiently use of inputs and effectively manage of production practices at the farm level. Thus, the present study aims to measure the technical efficiency and establish core factors affecting boro and aman rice production in Bangladesh. The study employed mainly farm level data collected from 80 farm households selected randomly in Dinajp...

Rice is the most widely consumed staple food for both developed as well as developing world, more so for Asia. According to the data of FAOSTAT (2012), rice has the third-highest worldwide production after sugarcane and maize, among all agricultural crops [1]. Developing countries account for 95% of the total rice production, with China and India contributing for nearly half of the world output...

Rhizoctonia solani AG1-IA, is the most economically important disease in Texas and other southern rice-producing states. The disease is widespread and occurs every year. The disease was first reported in Japan in 1910, and was soon well established in many Asian countries (Lee and Rush, 1983). The pathogen is capable of infecting rice, soybeans, grass weeds, and hundreds of other plant species ...

Alternariol and alternariol monomethyl ether are commonly associated with weathered grain sorghum. Production of these metabolites and altenuene by isolates of Alternaria alternata was evaluated on various sterile grain substrates. At 35% moisture content and 25 C, metabolite yields were highest on rice, intermediate on sorghums, and lowest on wheat and yellow corn. Fourteen-to 21-day cultures ...

Use of alkali-pretreated rice straw and untreated rice straw as substrates for enzyme production under solid-state cultivation was investigated. Cellulase produced from untreated rice straw showed higher activity of FPase, CMCase, β-glucosidase, and xylanase at 6.25 U/g substrate, 111.31 U/g substrate, 173.71 U/g substrate, and 433.75 U/g substrate respectively, as compared to 1.72 U/g substrat...

Addition of straw is common practice in rice agriculture, but its effect on the path of microbial CH(4) production and the microbial community involved is not well known. Since straw from rice (C3 plant) and maize plants (C4 plant) exhibit different δ(13)C values, we compared the effect of these straw types using anoxic rice field soils from Italy and China, and also a soil from Thailand that h...

In Japan, greenhouse gas emissions from rice production, especially CH4 emissions in rice paddy fields, are the primary contributors to global warming from agriculture. When prolonged midseason drainage for mitigating CH4 emissions from rice paddy fields is practiced with environmentally friendly rice production based on reduced use of synthetic pesticides and chemical fertilizers, Japanese ric...
