SUMMARY
Present study was undertaken to find out the performance of different single cut forage sorghum genotypes under different fertility levels. The field experiment was conducted at Forage Section Research Farm, CCS Haryana Agricultural University, Hisar (Haryana), India during Kharif season, 2015. Genotypes SPH 1752, CSH 13 and HJ 541 were sown at 50 %, 75 %, 100% and 125 % of RDF, where RDF was 80 kg N, 40 kg P2O5 and 40 kg K2O /ha . Significantly highest green fodder yield was recorded in HJ 541 (493.8 q/ha) and dry matter in SPH 1752 (115.2 q/ha) as compared to CSH 13 genotype. The maximum net returns (26262.4) and B:C ratio (1.74) was observed in genotype HJ 541. On comparison with different fertility levels, highest green fodder (516.37 q/ha) and dry matter (125.08 q/ha) were recorded under 125% RDF. The maximum net returns (Rs. 28095.9 q/ha) and B:C ratio (1.78) were observed with the application of 100% RDF followed by 125%, RDF 75% RDF. Conclusively, the genotypes, HJ 541 and SPH 1752 performed better and the application of RDF was the most suitable and economical fertilization practice.
