SUMMARY
A field experiment was conducted at Forage Section Research Farm, CCS Haryana Agricultural University, Hisar, during kharif 2022 on single-cut forage sorghum grown as rainfed crop to assess the impact of nano urea on fodder productivity, nutritional content, economics along with soil health. The experiment consisting of eleven treatments i.e., T1: Control (No RDN); T2: 100% RDN by urea fertilizer (75kg); T3: 100% RDN (100% through nano-urea in three sprays at 15, 30 and 45 DAS); T4: 100% RDN (50% as basal by urea fertilizer + 50% through nano-urea in one spray at 30 DAS); T5: 100% RDN (50% as basal by urea fertilizer + 50% through nano-urea in two sprays at 30 and 45 DAS); T6: 75% RDN (Through nano-urea in three sprays at 15, 30 and 45 DAS); T7: 75% RDN (50% as basal by urea fertilizer + 50% through nano-urea in one spray at 30 DAS); T8: 75% RDN (50% as basal by urea fertilizer + 50% through nano-urea in two sprays at 30 and 45 DAS); T9: 50% RDN (Through nano-urea in three sprays at 15, 30 and 45 DAS); T10: 50% RDN (50% as basal by urea fertilizer + 50% through nano-urea in one spray at 30 DAS); T11: 50% RDN (50% as basal by urea fertilizer + 50% through nano-urea in two sprays at 30 and 45 DAS) were evaluated in randomized block design with three replications. The results of pre soil analysis revealed that the experimental field was low in organic carbon (0.45) and available nitrogen (142.8 kg/ha), medium for available phosphorus (12 kg/ ha) and higher in potassium content (254.6 kg/ha). Furthermore, the lowest HCN content of fodder sorghum was recorded with 50% RDN (Through nano-urea in three sprays at 15, 30 and 45 DAS), while the highest crude protein, N, P and K content in sorghum were observed with application of 100% RDN by urea fertilizer (75 kg). Available soil nutrients were found highest with application of 100% RDN by urea fertilizer having highest available nitrogen (145.60 kg/ha), phosphorus (12.88 kg/ ha) and potassium (253.60 kg/ha) content. The cost of cultivation was found lowest with control whereas, maximum gross returns (Rs. 81,292/ha), net returns (Rs. 41,167/ha) and B:C (2.03) were found with 100% RDN by urea fertilizer.
