Batanghari Regency is one of the regencies in Jambi Province that has a potential for development lowland rice commodities. Rice farming consists organic and inorganic rice. Organic technique using fertilizer (compost fertilizers) can be broken down by decomposer organisms. The continuous use chemical fertilizers pesticides on agricultural land results decrease structure composition nutrients s...

Human excreta is a low cost source of nutrients vital to plant growth, but also a source of pathogens transmissible to people and animals. We investigated the cost-savings and infection risk of soil transmitted helminths (STHs) in four scenarios where farmers used either inorganic fertilizer or fresh/composted human excreta supplemented by inorganic fertilizer to meet the nutrient requirements ...

A survey of China's plant biotechnologists shows that China is developing the largest plant biotechnology capacity outside of North America. The list of genetically modified plant technologies in trials, including rice, wheat, potatoes, and peanuts, is impressive and differs from those being worked on in other countries. Poor farmers in China are cultivating more area of genetically modified pl...

Approximately 30% of the cultivated rice area in India is prone to crop damage from prolonged flooding. We use a randomized field experiment in 128 villages of Orissa India to show that Swarna-Sub1, a recently released submergence-tolerant rice variety, has significant positive impacts on rice yield when fields are submerged for 7 to 14 days with no yield penalty without flooding. We estimate t...

Although Vietnam is one of the biggest rice exporters today, there is an urgent need to restructure the sector. To guide the transition from being a quantity-focused producer to a credible supplier of quality rice, this study explores the sector’s opportunities for sustainable value chain upgrading. Data was collected through focus group discussions with farmers, stacked surveys with rice value...

This paper explores the dynamics of smallholder technology adoption, with particular reference to a high-yielding, low-external input rice production method in Madagascar. We present a simple model of technology adoption by farm households in an environment of incomplete financial and land markets. We then use a probit model and a symmetrically trimmed least squares estimation of a dynamic Tobi...

This paper describes how the social capital of rice farmers of the Mekong Delta of Vietnam, as manifested in the tradition of collective farming practice, has changed. Collective rice farming persisted for decades, irrespective of critical events that challenged its continuation, due to two key factors: the high need for collective farming to ensure subsistence, and the availability of a closel...

The paper explores the potential of Khao Dawk Mali expansion in Northern Thailand as well as presents estimation of demand for variable inputs and choice of rice varieties as jointly determined by the profit-maximizing farmers. Results reveal that, Khao Dawk Mali provides economic advantage over glutinous varieties and can be conceived as a better alternative crop particularly in areas with ina...

The economic value of irrigation water was determined through Contingency Valuation Method and Crop-Water Production function during wet and dry season of paddy cultivation. Factors namely, area under rice and water requirement influenced the willingness to pay for water by farmers. Social values of farmers’ over water were found to be high. The comparison of the economic value of water estimat...

among the agricultural crops, rice has had the largest share in pesticide use. most of the croplosses are caused by the attack of chilo suppressalis. the purpose of this study was toexamine effective factors on adoption of biological control by farmers in talesh region ofiran. a survey study was conducted using a stratified random sampling to collect data fromfarmers in the selected rural areas...
