Ranchi: Even though Jharkhand has received normal rainfall during the rainy season this year, the spatial distribution remains very uneven.
The cumulative rainfall in the state was recorded at 735.5mm until Monday as a normal rainfall of seasonal 754.3mm, showing a shortage of 2%, which was considered normal in meeting.
However, spatial variations in the distribution of rainfall have been substantially and from 24 districts, 11 are in two extremes.
While 13 districts have received almost normal rainfall, five – Lohardaga, Lahtar, coderma, Dhanbad and Jamtara – have received excess rainfall with deviations of 57%.
Against the normal 708.2mm, Lohardaga until the date has received rainfall of 1,109.5mm until Monday.
Conversely, Adjoining Gumla which should receive 829.7mm rainfall, has received only 515.6mm which shows a shortage of 38%.
Gumla is in groups of six districts who have a lack of rainfall which also covers the majority of Southwestern District – Simdega, Khunti, West Singhbhum, Seraagela, Kharsawan and Chatra.
In the case of Kharif plants, even though the monsoon rain is very important, with almost normal rainfall recorded in all states, experts believe that the rain deficit in six districts may not cause adverse effects.
Agrometers and weather scientists at Birsa Agricultural University, Abdul Wadood, said the excess rain could be a cause of fears for farmers than in the rainfall district.
“Until now the coverage of rice plants is good and if there is no prolonged dry mantra, there will be no bad impact on plants,” he said.
Agricultural experts have noticed that crop failure is not related to the lack of rain quantum but not evenly distribution of seasonal distribution, marked with a long dry mantra.
Wadood, however, expressed concern about corn plants and pulse in districts that had received excess rainfall.
“Water stands harming corn and pulses and they can suffer badly even if water stands more than 24 hours,” he said.
But farmers have been trained to follow Ridge and groove systems for corn and pulses to ensure natural drainage, he added.
Excess rainfall is much worse for plants than deficits, say experts
