Influence of Dates of Sowing and Spacing on Growth and Yield of Sorghum (Sorghum bicolor L.)

The present study aimed to investigate the influence of Dates of sowing and Spacing on Growth and Yield of Sorghum (Sorghum bicolor L.). A field experiment was carried out 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. The treatments consist of Dates of sowing 1stfortnight June,2ndfortnight June,1stfortnight July and Spacing of S1- 20×15cm, S2- 40×15cm, S3- 60×15cm. 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 (207.41cm), higher plant dry weight (94.86 g/plant), higher number of Grains/ear head (1588.30), higher Test weight (14.93 gm), and higher Grain yield (5.57 t/ha) yield were significantly influenced with sowing time of 2ndfortnight June along with the spacing 40×15cm.
