Potentials of sludge, woolen carpet waste and press mud on growth, yield and nutrient acquisition of rice

The digested sludge, woolen carpet waste and pressmud are the potential organic source for rice crop not only supplying N, P, K and organic carbon but also micronutrients such as Fe, Mn and Cu. Organic sources of N brought marked improvement in growth attributes of rice viz. total tillers m⁻², dry matter production and Leaf area index which is comparable with the effect of inorganic sources of N on these growth attributes. Similar trend was also observed with the grain yield, straw yield and yield attributing characters in rice. Through these are organic sources of N there was also phenomenal increase in the N, P, K, S, Fe, Mn and Cu content in the rice straw and grain indicating another effective and superior organic sources of N against other organic sources of N such as FYM, compost or green manures.
