Differentiation between protective irrigation and productive irrigation :
Protective irrigation- (i) It protects the crops from adverse effects of soil moisture deficiency. (ii) Irrigation acts as a supplementary source of water over and above rainfall. (iii) Provides soil moisture to maximum possible area.
Productive irrigation- (i) It provides sufficient soil moisture in the cropping season to achieve high productivity. (ii) In such irrigation the water input per unit area of cultivated land is higher than protective irrigation. (iii) Productivity is high.
