Description Journal article
Wheat (Tritium aestivum L.) is the major food crop of
India contributing 12 per cent of the total food grain
production, covering an area of 31.5 Mha with production
and productivity of 86.5 Mt and 2.8 tha-1 respectively
(http://eands.dacnet.nic.in/). In India, wheat is grown during
November to March, as it requires cool and moist weather
during the vegetative phase, and warm and dry weather
during reproductive phase. Cardinal (minimum, maximum
and optimum) temperature is one of the most critical parameter
that decides fate of crop productivity in wheat. However,
wheat sowing after rice is delayed because of late harvesting
of rice, large turn around time and poor soil tilth of seed bed
which forces delaying of wheat sowing to varying degrees.
Wheat yield under such circumstances is mainly affected by
terminal heat and water stress.Reproductive phase is the
ultimate determinant of yield, if faces high temperature
stress shows a significant impact on yield (Mitra and Bhatia,
2008). Different wheat cultivars take different time from
germination to maturity under varied agro-climatic
condition. Therefore, crop development phases alone cannot
be considered as a good predictor for measuring abiotic
stress. The more scientific way of characterizing abiotic
stressis through meteorological indices like growing degreedays,
heat use efficiency, etc. Considering all these, a study
was undertaken to investigate the impact of sowing date on
yield, heat and water use efficiency of three wheat cultivars
in Indo-Gangetic Plains of India.
