According to scientists of the Indian Council of Agricultural Research (ICAR) and other agricultural experts, the quantum of monsoon rainfall is "more or less good" for both kharif and rabi crops in the northeastern and eastern region in the country.
"After analysing the latest data and necessary weather conditions by the top IMD officials on Monday, it was declared that the southwest monsoon has withdrawn from eastern, northeastern states and most parts of India during the past few days," IMD Director Dilip Saha told IANS.
"The onset of southwest monsoon from Kerala and then eastern India is normally in June and the withdrawal starts from northern India around September 30," he said, adding that the withdrawal of southwest monsoon normally begins in the northeastern region from first and second week of October, though this year, both the onset of monsoon from Kerala and withdrawal of monsoon in the northern parts of the country were slightly delayed.

According to ICAR scientist B. K. Kandpal, the quantum of monsoon rainfall is "good for rabi crops" in the northeastern and eastern region in the country.
"During the sowing of rabi or winter crops, the farmers would not face the moisture related bad effect. We expect good productions of winter crops in the region," the scientist told IANS over phone from Meghalaya.
