| dc.description.abstract | A field experiment was conducted to know the effect of conjunctive application of sewage sludge and fertilizers on crop productivity and soil health under hybrid rice- wheat cropping system taking rice and wheat as test crop. As sewage sludge being a cheap source of organic matter and plant nutrients, it may use as fertilizer to full fill the requirement of deficient nutrient soils. Continuous use of sewage sludge reduces the nutrient requirement of the soil considerably. Application of sewage sludge improves soil physical, chemical and biological properties and consequently increases crop productivity.Rice and Wheat are most important staple food crops for more than half of the world population, especially for south-eastern Asia. The present study is a part of a more extensive investigation that forms the basis of adapting strategies to utilize the wastes collected from sewage treatment plant for its agricultural use.Owing to above points, the present investigation was carried out to study theeffect of conjunctive application of sewage sludge and fertilizers on crop productivity and soil health under hybrid rice- wheat cropping system.The experiment was set up in randomized block design with 10 treatments and three replicationstaking rice (Arize-6444) and wheat (HD-2967) as test crop. Application of sewage sludge along with fertilizer significantly improves the rice and wheat yield and soil fertility status as compared to the control and 100% RDF. Addition of sewage sludge significantly increased OC in post-harvest soil which improved the soil health and fertility status as compare to the 100% RDF. Application of sewage sludge also resulted heavy metals buildup in the post-harvest soil but the heavy metals content were below permissible limit as suggested by USEPA, 1993. The heavy metals content in applied sewage sludge was below the permissible limit. Overall sewage sludge along with fertilizer showed a significant increase in yield and improvement in properties of post-harvest soil. | en_US |
