Crop water requirement of rice in different agroclimatic zones of Jharkhand
The crop water requirement of rice in different agroclimatic zones of Jharkhand, India was estimated using the CROPWAT 8.0 and CLIMWAT 2.0 models with data collected through NASA data-access-viewer on climate, soil, crop, and water availability. The evapotranspiration (ETo), effective rainfall (Peff), and crop water requirement (CWR) for the four zones of the Jharkhand State were calculated. Results revealed that the reference evapotranspiration (ETo) varied from 420.4 mm to 516.5 mm during the crop growing season of rice in different zones. The effective precipitation varied from 748.4 mm to 760.8 mm. The crop water requirement of rice varied from 482.5 mm to 592.4 mm. Effective rainfall was sufficient to meet the water requirement of rice in most of the zones except Alluvial zone wherein the net irrigation water requirement was only 67.6 mm.
期刊介绍:
The Journal of Agrometeorology (ISSN 0972-1665) , is a quarterly publication of Association of Agrometeorologists appearing in March, June, September and December. Since its beginning in 1999 till 2016, it was a half yearly publication appearing in June and December. In addition to regular issues, Association also brings out the special issues of the journal covering selected papers presented in seminar symposia organized by the Association.
