Effect of different sowing times on the plant developmental parameters of wheat (Triticum aestivum L.): A review

Abstract

Studies on plant development phases and yield component patterns of wheat are essential for a better understanding of adaptation in wheat. Temperature is an important climatic factor which has profound effects on the yield of rabi crops. Changes in temperature affect the grain yield, mainly through phenological development processes. Winter crops are especially vulnerable to high temperature during reproductive stages and differential response to temperature change (rise) to various crops has been noticed under different production environments. The effect of temperature on the wheat phenological can easily by seen in Central India because of high inter-annual fluctuations in the productivity due to fluctuations in temperature. The productivity of wheat is largely dependent on the magnitude of temperature change. 1 °C increase in temperature throughout the growing season will have no effect or slight increase on productivity in North India. But, an increase of 2 °C temperature reduced potential grain yield at most of the places (Agrawal and Sinha, 1993). Deshmukh et al. (2015) reported that significant increase yield when the wheat crop was sown at 45 MW than 48 MW. Grain yield was significantly higher when crop was sown at 45 MW sowing.
