Scientists developed heat tolerant varieties to avoid the stress of heat to the wheat crop

Among the various climate hazards, heat stress is most important, which disrupts crop production. Damage related to heat during the reproductive phase severely affects crop yield. Terminal heat stress in wheat leads to morphophysical changes, bio -chemical disruption and genetic capacity.

Heat stress in the wheat crop affects the  production of roots and twigs, double ridge phase and initial biomass in the botanical phase. The final poor consequences of heat stress include the amount of grain, weight loss, slow grain filling rate, decrease in quality of grain and decrease in grain filling period.

In today's modern era where there is a steady increase in temperature. There is summer in the winter season, due to which the rabi crop has had a very bad effect on production. Due to which farmers are also facing a lot of damage.

Scientists of Indian Agricultural Research Institute developed heat tolerant varieties

Scientists of the Indian Agricultural Research Institute have developed new varieties of wheat to increase the production of wheat crops. These varieties can also give good yield in the increase in temperature in the months of March,  April. Such genes have been added to these varieties, which will not allow crop productivity to decrease in high temperatures.

Farmers can also sow these varieties with time and delay. During a conversation with a senior scientist at the Indian Agricultural Research Institute, it has been learned that he has developed a lot of wheat varieties which are appropriate for timely sowing and delayed sowing.

Varieties of wheat developed by Indian Agricultural Research Institute

The Indian Agricultural Research Institute has developed several varieties which will also give good yield by tolerating the heat of March and April. Agricultural scientists have developed many new varieties whose sowing will give farmers good production. You will get to see the names of these varieties below.

HD- 3117, HD-3059, HD-3298, HD-3369, HD-3271, HI-1634, HI-1633, HI- 1621, HD 3118 (Pusa Vatsala) All these varieties have been developed by Indian Agricultural Research Institute. . These varieties have the ability to tolerate higher temperatures in March and April.

According to scientists at the Indian Agricultural Research Institute, agricultural management techniques can also reduce heat stress in  wheat.

Farmers can also reduce heat stress in wheat crops by changing some agricultural management techniques - such as protection to reduce soil moisture loss, using balanced dosage of fertilisers, duration and methods of sowing etc. To reduce the effects of excessive heat, using external preservatives, wheat can be prepared better when grown in a warm environment.

Apart from these, mulching can be a good option to reduce water scarcity due to heat stress, especially in rain -based areas where water availability is a serious concern. Organic mulch helps maintain soil moisture,  plant growth and improve nitrogen use efficiency.
