Abstrakt: It is imperative to develop integrated fertilization strategies for various forage crops that enhance the competitive ability of the crop, increase crop production and reduce the risk of nonpoint source pollution from fertilizers. The objectives of this study were to determine the effect of different sources of nutrients on performance of sorghum sudan grass hybrid-oat cropping system. Significantly highest plant height, shoots per square meter, leaf stem ratio and dry matter accumulation of sorghum sudan grass hybrid and oat was observed with FYM @10 t ha−1+Azotobacter+PSB. Not surprisingly, plant height, shoots per square meter, leaf stem ratio and dry matter accumulation increased with increasing fertilizer levels with highest values recorded with 100% RDF. Moreover, significantly highest total green and dry forage yields and gross as well as net returns were recorded in FYM @10 t ha−1+Azotobacter+PSB as well as 100% RDF. FYM @10 t ha−1+Azotobacter+PSB resulted in higher benefit cost ratio, while, significantly highest benefit cost ratio was also recorded with 100% RDF. The system productivity and production efficiency showed its maximum value in FYM @10 t ha−1+Azotobacter+PSB as well as highest level of NPK fertilization. [ABSTRACT FROM AUTHOR]
