SUMMARY

An experiment was carried out during 2009-12 to study the impact of different nutrient sources on yield and quality of multicut fodder sorghum CO(FS)29. The mean of three year  data of the  experiment conducted to identify suitable organic source  showed that, poultry manure (PM) applied @18.8 t/ha + 2 kg Azospirillum+2 kg Phospho bacteria recorded 167.6 t green fodder yield/ha/year. The crude protein content got increased in the FYM applied treatment. The higher organic carbon content of 1.12% recorded in FYM applied plot followed by poultry manure applied treatment (0.99%) from the initial carbon status of 0.62%. The poultry manure applied plot recorded higher available N content of 185, kg ha-1. The PM applied plot observed higher net return of Rs.1,16,500 with B/C ratio of 4.7.

Key words: Multicut fodder sorghum, crude protein, FYM, poultry manure, fodder yield, soil nutrient balance, net return
