Influence of Nitrogen and Spacing on Growth and Fodder Yield of M P Chari (Sorghum bicolor L.)

Abstract

A field experiment was conducted during Zaid season of 2022 at the Crop Research Farm, Department of Agronomy, Naini Agricultural Institute, Sam Higginbottom University of Agriculture, Technology And Sciences, Prayagraj (U.P.) India. To study the Response of Nitrogen and spacing on growth and fodder yield of Sorghum (Sorghum bicolor L.). The treatments consist of Nitrogen 60,80,100 kg/ha and spacing of S1- 35×15cm, S2- 45×15cm, S3- 55×15cm. There were 10 treatments each replicated thrice. The soil of experimental plot was sandy loamy in texture, nearly neutral in soil reaction (pH 7.8), low in organic carbon (0.35%) available N (163.42 kg/ha), available P (21.96 kg/ha) and available K (256.48 kg/ha). Results revealed that the higher plant height (186.96 cm), higher plant dry weight (52.78 g/plant), higher crop growth rate (55.0 g/m2/day) and higher green fodder yield (28.36 and 22.43 t/ha) for 1st and 2nd cutting were significantly influenced with Nitrogen 100 kg/ha along with the spacing 55×15cm.
