Effect of plant density and nitrogen fertilizer on some attribute ofgrain sorghum (sorghum bicolor (l.) moench)
Journal Title: International journal of Advanced Biological and Biomedical Research - Year 2013, Vol 1, Issue 12
Abstract
A field experiment was conducted in 2010, to evaluate the effects of plant density (D1, D2 and D3: 8, 14 and 20 plant/m2) on field performance of Sorghum under different nitrogen application rates (N1, N2 and N3: application of 40, 80 and 120 kg/ha Nitrogen, respectively). The experiment was arranged as factorial based on randomized complete block design in three replicates. Results indicated that as plant density increased tillers per plant, Steam diameter and days to 50% flowering decreased, the effects of N application rate on these traits were not significant. While tillers per unit of area increased as more plant density. Plant height not affected by both treatments. As plant density and N application rates raised grain yield increased. Thus, N application and plant density increases can raise yield of grain sorghum.
