Abstract:

The present investigation entitled “To find out sensitive crop growth stages of wheat crop of weather in Raipur condition” was carried out during Rabi seasons of 2015-16 at Research and Instructional Farm of Indira Gandhi Krishi Vishwavidyalaya, Raipur Raipur to examine to validate the results of crop weather relationship of different wheat varieties grown under different growing environments rice based cropping system. The treatment combinations of three sowing dates (15 November, 30 November, 15 and December) and three varieties (Kanchan, HD-2967, and CG-1013) were laid out in a randomized block design with three replication.

The Phenological events such as CRI, tillering, ear emergence, 50 percent flowering, milking, dough and maturity stages decreased appreciably with delay in sowing. However, days for these phenological events varied from variety to variety due to their response to different environments.

In minimum temperature was no significant effect on CRI stage, EMR, 50% flowering and maturity stages but other stages like tillering, milk and dough stages are significant on minimum temperature during crop cultivars.

Maximum temperature during all stages significantly and adversely influenced the grain yield of kanchan variety of wheat (except the Max-T at maturity of kanchan). The negative significance of the adverse effect of maximum temperature on yield of wheat kanchan variety (based on probability values associated with t statistics) was highest during 50% flowering stage and it was followed by milk stage. The highest significant effect of rainfall was observed during 50% flowering. Rainfall at crucial phases of CR, tillering, emergence, 50% floweing, milking and dough stages is helping to meet the crop water requirement which includes maintaining soil moisture status and evapo-transpirational losses.
