Abstract

A field experiment was conducted during the kharif season of 2022 to evaluate the effect of fertilizer levels on the fodder yield and quality of sorghum genotypes in a randomized block design. Treatments consisted of two single-cut forage sorghum cultivars (HJ 541 and Duggi) and seven different fertilizer treatments comprising control, 50% recommended dose of fertilizer (RDF), 100% RDF, 150% RDF, RDF minus N, RDF minus P, and RDF minus K. Sorghum variety HJ 541 demonstrated superior characteristics for parameters like green fodder yield (GFY), crude protein (CP), crude fat, Neutral detergent fibre (NDF), Acid detergent fibre (ADF), crude fibre (CF), hemicellulose, cellulose, lignin, phosphorus, potassium, iron and calcium. Fertilizer levels also played a crucial role, with higher CP and crude fat and lower NDF, ADF, and CF recorded at 150% RDF, on par with 100% RDF. The variety HJ 541 performed better than Duggi (a local cultivar) in yield and quality parameters under the experimental conditions studied. The present study provides better insights into their performance and enables the effective utilization of the outcome, contributing to the ongoing research in this area.
