SUMMARY

A field experiment was conducted on multi-cut fodder sorghum [Sorghum bicolor (L.) Moench] to determine the effect of nitrogen on yield, growth and proximate analysis at Punjab Agricultural University, Ludhiana, Punjab during the Kharif season 2018. The experiment was laid out in Randomized Complete Block Design (RCBD), using three replications. The results showed that increasing nitrogen dose increased all yield and growth attributes. All the parameters studied showed significant differences in first, second and third cuts. The genotype SPH 1840 due to higher GFY revealed significantly higher gross returns (Rs 93745), net returns (Rs 52913) and B:C ratio (2.29). Therefore, it could be inferred that 125% RDF for each cut found optimum and economical which recorded higher green forage, DMY, higher quality parameters, net returns and B : C ratio.
