Performance of rabi Sorghum (Sorghum bicolor L.) Genotypes under rainfed conditions at varying fertility levels

摘要

Field experiments were carried out during winter season for two years viz., 1997-98 and 1998-99, at Sorghum Improvement Project, Rahuri, to study the performance of rabi grain Sorghum genotypes under rainfed conditions at varying fertility levels. Thepooled data, indicated that the hybrid CSH-15R and improved variety SPV-1155 gave significantly higher grain and fodder yield than SPV - 1359 and M-35-1 during both years. The growth and yield contributing parameters viz., grain weight 1000 grain weightand harvest index were higher in the variety SPV-1155 Application of 60 kg N+30 kg P_2O_5/ha, significantly increased the grain and fodder yield over the control during both years in pooled data. The same trend was observed in growth & yield contributing characters.
