摘要

A field experiment was carried out during the rabi season of 2009-10 in sub-Himalayan plains of West Bengal to evaluate the performance of some advanced wheat genotypes under late sown (December 23) and very late sown (January 05) condition. The experiment was laid out in split-plot design with nine genotypes, randomly allotted to main-plots; while two dates of sowing were allocated randomly to sub-plots. The study revealed that all the genotypes exhibited higher biomass production under late sown condition than very late sown condition. All the genotypes taken in the experiment matured within 100-105 days under very late sowing condition signifying that the genotypes took 5-13 days less time for maturity. Yield advantage was recorded up to 23.13% in late sowing over very late sowing. Delay in sowing from mid-December to first week of January resulted in significant decrease in major yield attributing characters viz., number of earheads/sq. m as well as number of grains/spike. Amongst the genotypes, maximum yield was achieved in DBW 14 (36.84 q/ha), closely followed by HI 1563 (34.98 q/ha). Both the varieties could be treated as suitable genotypes having somewhat tolerance towards heat stress under this condition.
