Abstract:
To find out the most suitable variety of wheat after harvest of rice under late sowing condition in Chhattisgarh plain region an experiment was conducted during rabi season of 2011-2012 at the Research Farm of Indira Gandhi Krishi Vishwavidyalaya, Raipur. The treatment combinations of five sowing dates (26 November, 06 December, 16 December, 26 December and 05 January) and four varieties (Kanchan, GW-273, Sujata and Amar) were laid out in a Split plot design with three replication. Result reveals that accumulated growing degree days (GDD) for different varieties under different thermal environments varied considerably from sowing to maturity. Different wheat varieties responded differently in terms of accumulated GDD at the time of maturity. Higher GDD was observed under D1 (26 November) in varieties Sujata and Amar. highest PTU was observed in D5 (05 January) in Kanchan and GW-273 while Sujata and Amar showed higher PTU value in D1 (26 November). Similar trend was also found in case of the highest Heliothermal Units (HTU) was observed under D5 (05 January) in varieties Kanchan and GW-273 where as Sujata and Amar showed the highest value of HTU in D1 (26 November). In case of grain yield of wheat, dates of sowing significantly influenced grain yield (kg/ha) in different varieties. Maximum grain yield was observed in D1 as compare to delayed sowings (D2, D3, and D4). Under the D1 the grain yield was observed maximum in Sujata and minimum in Kanchan.
