CROP WATER REQUIREMENT FOR MAJOR CROPS GROWN IN VARIOUS AGRO-CLIMATIC ZONES OF ODISHA
Journal Title: International Journal of Agricultural Science and Research (IJASR) - Year 2017, Vol 7, Issue 1
Abstract
The present study aimed to find out the crop water requirement for the major crops grown in various Agro-climatic zones of Odisha. Results revealed that water requirement for Kharif season ranges from 333 mm to 480 mm for short duration paddy crop, from 470 mm to 629 mm for medium duration paddy crop and from 600 mm to 821 mm for long duration paddy crop, all over Odisha. Water requirement for Rabi season paddy varies from 402mm to 659mm, groundnut ranges from 270mm to 330mm, green gram ranges from 201mm to 317mm, black gram ranges from 242mm to 270mm, maize ranges from 290mm to 363mm, millet 269mm, sesamum ranges from 460mm to 494mm for all the zones. In summer season, short duration paddy is cultivated in some areas of Odisha. The water requirement varies from 540mm to 658mm. The crop reference evapotranspiration was estimated for all the major crops grown in different agro-climatic zones of Odisha. From the daily rainfall, the surplus irrigation requirement can be applied the crops of respective localities.
