Life evolved in water, and water remains the essential medium in which various biochemical process takes place. With the occurrence of water deficits several physiological processes associated with growth are affected. The severe water deficits may lead to the death of the plant. In the present study effects of varying water regimes (watered daily, on alternate days, at 3 days interval, at 5 days interval and at 10 days interval) on the growth of Mustard (Brassica campestris cv Krishna Kranti) have been worked out. Results indicated that the impact of drought increased with the period of...

In developing countries, fast-growing urban populations are demanding more fresh water and food, while generating greater volumes of wastewater(WW). Due to the lack of comprehensive WW management, a major portion of the WW pollutes natural water bodies. For sustainable crop production, adequate level of inputs like inorganic fertilizers, manure and irrigation water finds great significance and their improper management has been the cause of land degradation and environmental pollution. The WW contains a lot of nutrients which may increase the yield of crop and at the same time may substitute...

Les coccinellidés jouent un rôle important en tant qu'agents de lutte biologique, tant au stade larvaire qu'au stade adulte, sur plusieurs espèces proies, en particulier les pucerons, les coccidés et de nombreux autres insectes à corps mou, qui endommagent le maïs, le colza, le blé, les cultures fourragères (alpiste), les pois, le lin, les pommes, la luzerne et les pommes de terre. L'exploration de l'utilisation potentielle d'insectes ou d'acariens prédateurs pour lutter contre les pucerons ravageurs a reçu plus d'attention, car la lutte biologique est considérée comme...
