In India, agricultural soil has been deteriorated by various on-going practices involving application of chemical fertilizers, pesticides and effluents. Presently, Amritsar (Punjab), an agricultural land, is undergoing rigorous cultivation of wheat and rice crops which consequently increased the application of chemical pesticides and fertilizers for high yield. These agricultural practices are ...

Suitable substrates for laccase production by the thermotolerant basidiomycete Coriolus versicolor strain RC3 were screened using solid and liquid media. In liquid basal medium, 1%(w/v) rice bran as a carbon source was found to be the most efficient substrate for laccase production compared to 1%(w/v) glucose, wheat bran and rice straw meal. After 15 days cultivation at 37°C in shake flask cult...

Irrigation for rice cultivation increases the production of Anopheles gambiae, the main vector of malaria in Mali. Mosquito abundance is highly variable across villages and seasons. We examined whether rice cultivation patterns mapped using remotely sensed imagery can account for some of this variance. We collected entomologic data and mapped land use around 18 villages in the two cropping seas...

With the aim of searching for potent diazotrophic bacteria that are free of public health concerns and optimize rice cultivation, the endophytic colonization and plant growth-promoting activities of some endophytic diazotrophic bacteria isolated from rice were evaluated. Among these bacteria, the emerging diazotrophic strains of the genus Novosphingobium effectively associated with rice plant i...

BACKGROUND Rice-duck cultivation is the essence of Chinese traditional agriculture. A scientific assessment of the mechanism and its capacity is of theoretical significance and practical value in improving modern agricultural technology. RESULTS The duck's secretions, excreta and their treading, pecking and predation decrease the occurrence of plant diseases, pests and weeds, enrich species d...

−The objective of this study was to examine the light and heavy metals on the fruit body growth of Cordyceps militaris in the rice-based cultivation. Since heavy metals are commonly detected in the paddy field, we investigated the effect of lead, cadmium and mercury on the rice grain-based cultivation of C. militaris. Cordycepin and cordycepic acid were determined by HPLC method. The result sho...
