Abstract:
A field experiment was conducted to study the “Response of multicut fodder sorghum genotypes to nitrogen levels under irrigated condition in Northern Dry Zone (Zone 3) of Karnataka” in medium deep black soils at ICAR- Krishi Vigyan Kendra, Vijayapur, during Kharif 2019-20. The experiment was laid out under split plot design with three replications, the treatment consisted of two genotypes viz. (CoFS-29 and CoFS-31) and five nitrogen levels viz. (100, 125, 150, 175 and 200 kg ha-1). Nitrogen at all levels is divided into six equal parts and applied at sowing, 30 days after sowing and after each cutting four times. Entire doze of Phosphorus and potassium were applied at the time of sowing (40:40 kg ha-1). The crop was harvested for green forage at 50 percent flowering in each treatment at all the five cuttings. Forage quality parameters were analysed on whole plant dry matter basis.

Entire doze of Phosphorus and potassium were applied at the time of sowing (40:40 kg ha-1). The crop was harvested for green forage at 50 percent flowering in each treatment at all the five cuttings. Forage quality parameters were analysed on whole plant dry matter basis.
The genotype CoFS-31 recorded significantly higher total green fodder (130.49 t ha-1) and total dry matter yield (29.67 t ha-1) compared to CoFS-29 (114.59 and 26.14 t ha-1). Application of 200 kg N ha-1 recorded significantly higher total green fodder yield (154.32 t ha-1) and total dry matter yield (34.97 t ha-1) compared to other levels of nitrogen. Higher level of nitrogen improved the quality of fodder sorghum.
Higher total green fodder yield (167.05 and 156.28 t ha-1), total dry matter yield (37.52 and 35.78 t ha-1), gross returns (₹ 250575 and 234430 ha-1), net returns (₹ 176270 and 160447 ha-1), benefit cost ratio (3.37 and 3.17) and better quality parameters were observed under CoFS-31 genotype with supply of 200 and 175 kg N ha-1, respectively.
