Effect of different sowing dates and irrigation schedule on yield attributes of wheat varieties under Allahabad conditions

Abstract

A field experiment was conducted at the Forestry Nursery and Research Farm of Department of Environmental Sciences & Natural Resource Management, College of forestry, Sam Higginbottom University of Agriculture, Technology and Sciences, Allahabad during Rabi 2016-17 to study the interaction effects of different sowing dates and irrigation schedule on yield attributes of wheat varieties. The results revealed that spike length and grains per spike of wheat crop were significantly influenced by different dates of sowing, varieties and irrigation schedules. Among different varieties, sowing dates and irrigation schedules, the maximum number of spikelet per spike, grains per spike and grain yield was recorded with variety PBW-343, sowing of wheat on 25th Nov and 4 irrigations respectively while spike length was observed maximum with variety HD-2967, 25th Nov sowing and 4 irrigations. Sowing of wheat variety PBW-343 on 25th Nov along with 4 irrigations resulted in maximum spike length (15.04 cm), grains per spike (52.17) and grain yield (42.51 q/ha). Interaction effect of date of sowing, varieties and irrigation schedules was non-significant on spikelet per spike.
