A field experiment was conducted during kharif season of 2009 and 2010 at main Forage Research Area, CCS HAU, Hisar. The experiment was laid out in split plot design with three replications. Treatments comprised of three tillage methods (Conventional tillage, reduced tillage and minimum tillage) in main plot and four nutrient management treatments (control, 100% recommended dose of fertilizer (80 kg N+30 kg P2O5/ha) through inorganic fertilizers, 75% recommended dose of fertilizer (RDF) + 5 t FYM/ha and 50% RDF + 2.5 t FYM/ha + Azotobactor + PSB) in sub plot. The maximum plant height (243.2 in 2009 and 263.6 in 2010), number of tillers per meter row length (18.0 in 2009 and 14.0 in 2010), green fodder yield (362.4 q/ha in 2009 and 382.7 q/ha in 2010) and dry matter yield (104.4 q/ha in 2009 and 110.0 q/ha in 2010) were recorded in conventional tillage during both the years. Crude protein content and IVDMD percent were not influenced significantly by tillage and nutrient management methods. The maximum gross income and net income were obtained in conventional tillage with 100 percent recommended dose of fertilizer was applied as compared to other treatments.
Key words: sorghum growth, INM, productivity, quality and economics
