Abstract

An experiment was laid at Horticultural College and Research Institute, Tamil Nadu Agricultural University, Coimbatore during 2009-2010 to study the influence of seasons on growth, flowering, yield attributes and yield of Dolichos bean genotypes. The results revealed that the season, July-August sowing recorded more number of secondary branches, more number of pods, pod weight, pod length and yield. With respect to genotypes tried, the genotype Dbp-3 recorded more number of secondary branches, highest number of pods, pod weight, pod length and yield. The treatmental factor combinations performed with more number ofsecondary branches, highest number of pods, pod weight, pod length and yield was recorded in genotype Dbp-3 sown during July-August season. September-October season crop took about 84.3 days for first fruit harvest compared to earlier sown (i.e.) July- August season crop with 93.7 days. Days taken to first fruit harvest were earlier in CO-1 as compared to Dbp-3 and Dbp-4.
