Integrated effect of organic and inorganic fertilizers on yield, quality parameter and nutrient availability of sugarcane in calcareous soil

Author(s): UN Umesh, RK Prasad and Vipin Kumar
Abstract: A long term experiment under rice – sugarcane plant – sugarcane ratoon I – sugarcane ratoon II – Moong rotation was started during May, 1999 at Sugarcane Research Institute, Pusa, Bihar to evaluate the long term effect of different levels of nitrogen applied either alone or in combination with organic manures on yield and quality parameter of sugarcane as well as on soil health. The number of tillers, millable cane count, sugarcane and sugar yield were significantly increased at higher level of N when applied with organic manure where as the effect of biogas slurry (BGS) was found more pronounced. Similarly, juice quality was also significantly enhanced at higher N level in conjoint with BGS. The depthwise distribution of organic carbon and available nutrients like N, P, K, S and Zn content in post harvest soil after sugarcane plant as influenced by long-term intensive cropping system and continuous addition of organic and inorganic fertilizers indicated that organic carbon content regularly decreased with increasing soil depth and the rate of decrease was more in treatment receiving organic manures. Among the organic manures, sulphitated pressmud was found more effective followed by blue green algae and green manuring in accumulating organic carbon in surface soil. The available N, P, K, S and Zn content was higher in surface layer and it decreases progressively along with the depth upto 120 cm in all the treatments however, the rate of decrease was more in treatment receiving organic manures than inorganic fertilizer alone.
