| Abstract | ||
| An experiment was conducted at Field Crop Research Station of IPA Agricultural Research Center during fall seasons of 2001 and 2002 to investigate the effects of plant densities and nitrogen levels on some growth characteristics and grain yield of sorghum variety Ankad. Factorial experimental with a randomized complete block design arrangement with three replicates was used, plant densities (53333, 66666, 88888, 133333 plant/ha) were the first factor while nitrogen of was (100, 200, 300 and 400 kg N/ha) the second factor. Significant increments were attained by increasing plant population in number of days from planting to50% anthesis and grain yield, while decreasing in plant height, panicle length, number of branch /panicle and grain weight. Increasing nitrogen levels gave significant increments in plant height, panicle length, number of branch/panicle, grain weight and grain yield, while decreasing in number of days from planting to 50%anthesis. Results show that low plant densities and increasing nitrogen levels associated with increments of plant height, , length of panicle, number of branches/panicle, grain weight and grain yield, while number of days from planting to 50% of anthesis was decreased. Plant density 88888 plant/ha with 300kg Nha results maximum grain yield and improved growth characteristics. | ||
