In the last decades, rice yields in South Asian countries grew tremendously in one hand and a noticeable yield fluctuation on the other. The objective of this study was to examine the rice yield distributions, estimate yield risks at country level, and compare risks between five countries namely Afghanistan, Bangladesh, Nepal, Sri Lanka, and Pakistan. Anderson Darling (AD) test was applied to t...

The sustainability of rice productivity in Bangladesh is likely to face major threat due to water shortage during boro (winter season). The conventional transplanted boro rice requires huge amount of irrigation water due to wastage of various means. It is an imperative task that water saving production technology is needed to replace the conventional system for sustaining boro rice production i...

An experiment was conducted at Bangladesh Rice Research Institute (BRRI), Gazipur during T.Aman season of 2007 with a view to evaluating seven maintainer and 30 restorer lines for yield and yield contributing characters for selecting promising maintainer and restorer lines for developing rice hybrids in our local environment. Significant variations were noticed among the parental lines for all ...

(eds M.C.S. Wopereis et al.) 173 Since the early 1990s, several other countries (Bangladesh, Egypt, India and Vietnam) have developed and introduced hybrid rice technology to their farmers. The availability of adequately trained human resources is an essential prerequisite for developing and using hybrid rice technology. Hybrid rice breeding uses several concepts, skills and procedures that are...

The study was conducted at the Bangladesh Rice Research Institute Regional Station, Comilla, during three rice growing seasons. The experiment consists of six weeding treatments with three replications. The objective of the experiment was to determine an economic weeding method as well as to improve water management practices of paddy rice. The study indicates that the continuous ponding (100±1...

Irrigation of rice fields in Bangladesh with arsenic-contaminated groundwater transfers tens of cubic kilometers of water and thousands of tons of arsenic from aquifers to rice fields each year. Here we combine observations of infiltration patterns with measurements of porewater chemical composition from our field site in Munshiganj Bangladesh to characterize the mobility of arsenic in soils be...
