The various sources are generating a lot of polluting materials in the ponds water of Harahi & Gangasagar in the district of Darbhanga in Bihar. The sources are domestic drainagesthat directly discharge night soil from houses, medical wastes from doctor’s clinic as well as industrial garbage. It is due to the presence of houses, clinics, some industries near the Harahi and Gangasagar ponds. These wastes are very dangerous and hazardous in nature on one hand, and at the other hand may contain a lot of valuable materials which protect our environment. In view of safety, it is essential to treat these wastes properly to protect the environment. There are various ways by which toxic and valuable by-products can be separated. The toxic products can be properly discarded and valuable products can be effectively utilized. The authors present the physicochemical analysis of Harahi and Gangasagarpond water. The results obtained have been compared with standard values of “Bureau of Indian standard permissible limit for drinking water.”

Bread wheat (Triticum aestivum L.) is the most important cereal occupying a protruding position among major food crops in the world in terms of acreage and production and is an important cereal crop which is receives the most attention of specialists in plant breeding and production in the world wide in general and in Ethiopia in particular. This experiment was conducted on five bread wheat varieties Mandoyo, Mada-Walabu, Sofumar, Dure and Sanate against local check at Bule hora woreda to identify and recommend high yielder, insect pest tolerant, and stable varieties. The experiment was carried out in a Randomized Complete Block Design (RCBD), with three replications. Yield and yield related parameters were analyzed using SAS statistical software version 9.0. Most of yields and yield related components were significantly different between the varieties at 5% probability level. Based on the mean separation, the highest average grain yield was recorded from Sanate variety 3926.3 kg/ha while, the lowest average yield (2753.2 kg/ha) was recorded from Local check. From total analysis Sanate variety had a yield advantage over the check (Local). Therefore, we suggest that, farmers, state farms and other private bread wheat producers located at the study areas and with similar agro ecologies are recommended to use Sanate variety to increase bread wheat yield.
