Evaluation of Drip Irrigation System for Okra Crop under Tarai Condition of Uttarakhand, India
Journal Title: International Journal of Current Microbiology and Applied Sciences (IJCMAS) - Year 2018, Vol 7, Issue 3
Abstract
Drip Irrigation Method is the best method that has been used in the world among the other irrigation methods because of its good and high uniformity. This method distributes water to the field using the pipe network and transforms it from the pipe network to the plant by emitters. A field experiment was conducted at experimental farm of college of Technology, G.B.P.U. A & T, Pantnagar, Uttarakhand to evaluate the performance of drip irrigation system installed for okra crop. The different uniformity indicators were Distribution uniformity, Christiansen’s uniformity coefficient (CUC), Wilcox and Swails uniformity coefficient and Hart Uniformity coefficient. The performance of the drip system under investigation can be categorised as good to excellent. The Distribution Uniformity, Christiansen’s Uniformity Coefficient (CUC), Wilcox and Swails Uniformity Coefficient and Hart Uniformity Coefficient ranged from, 89.8 to 96.7, 92.4 to 97.8, 90.9 to 97.2 and 92.8 to 97.8 respectively. The highest crop yield for okra crop was reported in plot T1R3 (Drip irrigation based on 100% evaporation replenishment) which is having higher Distribution Uniformity, Christiansen Uniformity Coefficient, Wilcox and Swails Uniformity Coefficient and Hart Uniformity Coefficient values and lowest crop yield was reported in plot T3R2 (Drip irrigation based on 60 % evaporation replenishment) having lowest DU, CUC, UCW and UCH values. The result clearly indicated that increase in irrigation uniformity increases the crop yield. Water production functions were developed for okra crop considering irrigation depth and spatial uniformity of water application under drip irrigation. The developed production functions can be used for predicting crop yield for different depth of irrigation and uniformity.
