Heat wave, severe heat damages banana crop


Hajipur and Kosi areas of Bihar are identified as banana producers. Both tall and dwarf species of bananas are cultivated in these areas. Heat waves and severe heat have damaged the banana crop in recent years. Scientists also believe that the increasing frequency and intensity of heat waves (loo) year after year for many years, especially temperatures above 40 degrees Celsius, is posing a significant threat to banana cultivation. Scientists say that excessive temperature adversely affects the growth and development of banana. Professor Dr. S K Singh, Head of Department, Dr. Rajendra Prasad Central Agricultural University, Pusa, Samastipur and Principal Investigator of All India Fruit Research Project, told IANS that high temperature disrupts the hormonal balance required for flowering and fruiting in banana.

They say that the hormones that promote flowering get negatively affected by heat stress, leading to poor inflorescence development. Moreover, heat during the crucial flowering period will lead to abnormal flowering which may lead to less fruit set. According to the data of the Ministry of Agriculture, banana is cultivated in an area of ​​42.92 thousand hectares in Bihar, which gives a total production of 1968.21 thousand tonnes. The productivity of Bihar is 45.86 tonnes per hectare, while at the national level banana is grown in an area of ​​924 thousand hectares, which gives a total production of 33,062 tonnes.

It is said that for its cultivation, it is necessary that the temperature should be between 13 to 40 degrees. In winter, when the minimum temperature goes below 10 degrees, the flow of fluid inside the banana plant stops, due to which the growth of the banana plant stops and many types of disorders start appearing. Singh explains that the process of ripening of bananas accelerates due to heat wave, due to which the fruits ripen before time and the 'shelf life' of the fruits decreases. Due to the increase in the respiratory rate at high temperature, there is a rapid reduction of starch into sugar, due to which the fruits overripe and often burst. Farmers also believe that the banana crop has been affected by the heat wave. Meanwhile, scientists believe that the moisture level of the soil can be maintained through irrigation.
