Effect of Sowing Time and Plant Density on Yield Components of Sorghum Sorghum bicolor L. Moench

Abstract

Research was conducted in experimental plots of Field Crops Department, Faculty of Agriculture, Ankara University in the year of 1995. Variety of sorghum Beydar ı was sown on three sowing time April 20m• May 5th and May 20m and three plant density 40x10 cm, 40x15 cm and 40x20 cm . Depending on this research results could be summarized as follow: According to plant density as an average; the plant height 96,04, 89.05 and 78.88 cm; the .number of leaf per plant 10.77, 10.42 and 10.12; the length of flag leaf 23.51, 25.79 and 28.73 cm; the blade of flag leaf 4.58, 5.07 and 5.49 cm, the number of first branch of panicle 49.79, 52.88 and 55.28 ; the seed yield of per plant 26.63, 34.30 and 43.68 g respectively were obtained. The highest and lowest seed yield were determined in 40x20 cm plant density as 484.47 g/m2and 144.28 g/m2on sowing time April and May 20 respectively.
