Yield, Correlation Studies and Economics of Promising Sorghum (Sorghum bicolor L. Moench) Genotypes as Influenced by Plant Geometry and Fertility Levels

摘要

The field investigation was carried out during the rainy seasons of 2003 and 2004 to assess the effect of plant geometry and fertility levels of yield, correlation and economics of sorghum [Sorghum bicolor (L.) Moench] genotypes. CSH14 proved superiorgrain yield over CSV 15 and SPV 1430. The per cent increase in grain yield to the magnitude of 21.61 and 36.62 over CSV 15 and SPV 1430. Among plant geometry, 45 x 15 cm recorded significantly higher aforesaid parameters than 45 x 10 and 30 x 10 cm. Thewider geometry recorded significantly higher grain yield and narrow geometry (30 x 10 cm) recorded higher fodder yield. With respect to fertility levels, application of 100 % RDF recorded significantly higher in yields of sorghum over 50 and 75% RDF. 100% RDF recorded significantly higher in grain yield over 50 and 75% RDF to the magnitude of 38.96 and 14.97 per cent and was found at par with 125 % RDF.
