    Factoral and sectoral water productivity in a canal command
    (CCSHAU, 2006) Dixit, Abhishek; Ranvir Kumar
    Field research entitled “Factoral and Sectoral Water Productivity in a Canal Command” was conducted during 2005-06 on 12 outlets of Kabir and Sarsana minors of Bhakra Canal System to study the existing and optimized water productivity (WP) of agriculture and animal production systems at field, outlet and minor levels. The existing irrigation WP (WPIRR) at the outlet level varied from 0.55 to 0.70 in cotton, 1.30 to 1.74 in cluster bean, 1.35 to 1.64 in pearl millet (grain), 6.06 to 8.83 in pearl millet (fodder), 11.59 to 13.73 in sorghum (fodder), 0.55 to 0.77 in sorghum (grain), 0.53 to 0.63 in green gram, 1.22 to 1.28 in wheat, 13.07 to 12.12 in fenugreek, 0.31 to 0.34 in berseem,, 0.45 to 0.55 in chickpea and 0.58 to 0.73 kg/m3 in mustard. The WP in terms of monetary returns (WPNR) for the respective crops varied from 5.96 to 8.50, 12.08 to 16.50, 0.65 to 1.55, 2.40 to 4.72, 0.75 to 3.07, 1.57 to 2.04, 1.38 to 3.76, 1.61 to 2.34, 1.02 to 1.55, 0.91 to 1.46, 1.77 to 4.39 and 2.76 to 4.33 Rs/m3. With optimized irrigation schedule, using CROPWAT model, the WPIRR and WPNR increased by 24.7 and 34.5, 34.9 and 38.5, 20.1 and 64.3, 28.2 and 44.6, 28.4 and 56.7, 29.4 and 60.9, 38.0 and 52.5, 16.1 and 41.4, 21.0 and 52.0, 17.7 and 33.2, 25.4 and 39.5, 28.4 and 42.6%, respectively.Average livestock WPNR of buffaloes was 14.41 Rs/m3 for buffaloes and 6.76 Rs/m3 for cows. The optimal crop plan resulted in the increase in maximum net returns at different outlets by 33.1 to 45.5 %, as compared to the net returns under the existing crop plan.
