Abstract

Estimation of Net Irrigation Requirement (NIR) of crops is essential for agricultural planning, irrigation scheduling, regional water balance studies and optimal allocation of land and water resources in a canal command area. In the present study, NIR estimation of different crops of Limbasi Canal command area, Gujarat, India is carried out in the deterministic and stochastic regimes for nineteen years of available data. In the deterministic regime, the estimated average NIR of 19 years for kharif crops paddy & vegetables was 229.8 & 92.9mm ; rabi crops sorghum, tobacco, wheat & vegetables was 355.5, 391, 427.2 & 407.1mm and hot weather crops paddy, pearl millet & vegetables was 863.9, 600.6 & 754.7 mm respectively. In the stochastic regime, NIR of different crops was predicted at Probability of Exceedance (PE) levels of 0.02, 0.05, 0.08, 0.10, 0.15, 0.20, 0.25, 0.35 and 0.40 using 19 years of NIR. MATLAB was used for prediction of NIR. The goodness of fit was tested by Kolmogorov – Smirnov test and normal distribution was found as the best fit.

Keyphrases: limbasi canal command area, net irrigation requirement, probability of exceedance, reference crop evapotranspiration
