SUMMARY
The field experiment was conducted during kharif season of 2022 at Forage Research Farm of Department of Genetics & Plant Breeding, CCS Haryana Agricultural University, Hisar to study the effect of nano urea on sorghum for sustainable fodder production. The experiment was laid out in randomized block design keeping eleven treatments consisting of nitrogen fertilizers combinations of conventional and nano urea with three replications. There was significant difference among treatments in respect of growth, green and dry fodder yield of single cut forage sorghum. The maximum plant height (248.4 cm), number of leaves (14), leaf: stem (0.29), dry matter accumulation (153.62 g), leaf area index (7.55), green fodder yield (541.9 q/ha) and dry fodder yield (144.1 q/ha) were recorded with the application of 100% RDN by urea fertilizer (75 kg) as followed by 100% RDN: 50% as basal by urea fertilizer + 50% through nano-urea in two sprays at 30 and 45 DAS.
Key words: Sorghum, single-cut, fertilizer, fodder yield, nano-urea
