Studies on heat unites on various phenophases of wheat (Triticum aestivum) under different growing environment

Abstract

The present investigation entitled “Studies on Heat unites on various phenophases of wheat (Triticum aestivum) under different growing environment” was carried out during Rabi season of 2016-2017, at the Research Farm of Indira Gandhi Krishi Vishwavidhyalaya, Raipur to find out the wheat varieties under late sowing conditions in a rice based cropping system. The treatment combinations of three sowing dates (1st December, 11th December and 21st December,) and three varieties (Ratan, GW-273, and GW-366) were laid out in a randomized block design with three replication. The value of GDD, PTU, HTU, RUE and HTU for different varieties were recorded and maximum value in these parameter was found highest in GW-273 under D1 (1st December) growing environment.
