This paper discusses the success of an unintended area-wide integrated pest management (IPM) for Chilo suppressalis in Japan. Chilo was considered as one of the country’s major rice insect pests causing significant yield loss during the pre-war period, along with Scirpophaga incertulas . Chilo population density declined through the years, which was considered to be induced by modern farming te...

Despite the growing demand for organic products, research on organic farming (OF) such as genotype screening, fertilizer application and nutrition uptake remains limited. This study focused on comparisons of the apparent recovery efficiency of nitrogen fertilizer (REN) in rice grown under OF and conventional farming (CF). Thirty-two representative conventional Japonica rice varieties were field...

the impact of climate change does not only affect the production aspects but also on household income and other socioeconomic aspects. the research aims to determine the household economic behaviors of rice farmers in decision-making with relation to the production risks due to climate change and determine the farmer’s adaptation strategies in the face of climate change. the approach taken is t...

India is the largest producer of rice (Oryza sativa L.) next to China in the world. Rice cultivation is a huge water demanding enterprise. In recent years, water table has depleted at a very rapid rate throughout the globe, thus, posing alarming threats and limiting the scope for cultivation of high water consuming crops especially rice. Challenges in maintaining the sustainability of rice farm...

Analysis of the Indian census shows that female marital migration accounts for the majority of the spatial mobility in India. Using a unique panel dataset that is representative of rural India, I estimate the effect of increases in the value of female labor on women’s marriage market outcomes. Female labor is more valuable in rice farming than wheat farming. I exploit rainfall shocks across ric...

Implications of increasing labour costs and the development of herbicide resistance for profitable weed management in Philippine rice farming systems are investigated. The study employs RIMPhil (Resistance and Integrated Management in the Philippines), a bioeconomic simulation model developed to provide a comprehensive assessment of integrated weed management programmes for the control of annua...
