SUMMARY
A field experiment was conducted to assess the effect of foliar application of nitrogen- based formulations on quality and yield of fodder sorghum during summer 2022 at Forage Section Research Farm, Department of Genetics & Plant Breeding, CCS Haryana Agricultural University, Hisar (India). The experiment was laid out in randomized block design with fourteen treatments and replicated thrice. Among all the treatments, maximum green fodder yield (445.4 q/ha) was recorded with the application of T14 (nano-urea spray @ 0.6% at 35 DAS and 50 DAS), which was on a par with T11, T12 and T13. At harvest, significantly higher nutrient uptake (N, P and K) 202.79, 25.72, 161.81 kg/ ha and crude protein 9.94 % were recorded with foliar application of nano-urea @ 0.6% at 35 DAS (days after sowing) and 50 DAS, which was on a par with T11 (one nano-urea spray @ 0.4% at 35 DAS), T12 (two nano-urea spray @ 0.4% at 35 and 50 DAS) and T13 (one nano-urea spray @ 0.6% at 35 DAS) when RDF (recommended dose of fertilizer) was also applied. The HCN content across all treatments was non-significant at 30 DAS. However, the lowest HCN value (89.56 ppm) was observed in the treatment with absolute control (No RDF).
