Forced maturity in plants due to higher temperatures can result in smaller seeds

A comparatively 'warm' winter in Bihar this year could harm production of rabi crops like wheat, oil seed and pulses, agricultural scientists have predicted.

According to experts, production of winter crops may be hit by at least 30-40 per cent if the weather in the eastern state is unchanged for long.

The minimum temperature should be 10-12 degrees Celsius (°C) while the maximum temperature should be 18°C-21°C for better yield of rabi crop, said experts.

However, the minimum temperature has remained between 11°C and 18°C in Bihar. The average day temperature has gone up to 27°C over the last 10 days. Normally such kind of weather is seen in the February end or March.

“Warm weather and sudden high temperatures affect the photoperiodism of plants. If such weather continues, it will hamper tiller formation as well as grain filling of wheat crops. Sometimes, forced maturity occurs in case of high temperature in rabi crops,” RK Sohane, senior agriculture scientist at Bihar Agriculture University in Sabour (Bhagalpur), told Down to Earth.

He added low temperature is essential for vegetative growth of rabi crops.
