An experiment was conducted to determine the impact of fish and prawn culture on some physicochemical parameters of water, weeds, benthos, and rice yield under simultaneous method for a period of 5 months from July to November 2007. The experiment was comprised of five individual treatments having three replicates for each. The treatments were: rice combined with fish and regular urea fertiliza...

Rice-duck farming system is one of the means of organic rice farming, in which the weeds, diseases and insects could be effectively controlled with minimal or no pesticide and herbicide application. Whereas in conventional rice-duck farming system the controlling effect on diseases, insect pests and weeds was slowly disappeared after the rice heading stage at which ducks were driven out of the ...

Investigation was carried out from June to August 2009. A total of 40 fish farmers were selected from northwest two upazila namely Debigonj (n=20) and Boda (n=20) where both men and women were targeted. Focus group discussion (FGD) and cross-check interview were conducted to get an overview on carp farming. From 1991-1995, 1996-2000 and after 2000; 17.5%, 45% and 37.5% of fish farmers started c...

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...

A study was carried out at Mwea Rice Irrigation Scheme, Kenya, to assess the impact of rice husbandry on mosquito breeding and identify indigenous biocontrol agents with potential for controlling mosquito breeding in the scheme. The study established a close relationship between the schedule of the farming practices (particularly the flooding phase) and mosquito breeding. Two groups of agents, ...

This study endeavors to evaluate the effects of farmers’ training program on the adoption of improved farming practices, the output of rice farming, and the income as well as the profit from rice farming by employing an ex-post non-experimental data in Sierra Leone. It was established that participating in farmers’ training program increased the possibility of adoption of the improved farming a...

Organic farming provides many benefits in Indonesia: it can improve soil quality, food quality and soil carbon sequestration. This study was designed to compare soil carbon sequestration levels between conventional and organic rice farming fields in west Java, Indonesia. The results from soil analysis indicate that organic farming leads to soil with significantly higher soil carbon storage capa...

A field survey through questionnaire was conducted in rice-prawn (Macrobrachium rosenbergii)-fish culture ghers six villages of Khulna, Satkhira and Bagerhat districts south-west Bangladesh during March to December, 2008 assess present practices. About 10-25% the total area land converted for building canals dikes remaining were used rice cultivation. Boro with prawn fish appeared have positive...

Many cultivation practices have been improved in order to decrease environmental burdens of paddy rice production in Japan. Therefore, the importance of life cycle assessment (LCA) to assess the environmental impacts of whole production systems particularly that of rice production has increased. However, the applications of LCA to rice production are still limited, although rice is the staple f...
