Results
Based on the study, we have assessed the superiority of performance of four commands of
Telugu Ganga Project in Chittoor, Nellore, Kurnool and Kadapa districts in Andhra Pradesh
using standard performance indicators like Equity, Uniformity, Irrigation intensity, Overall
consumed ratio/efficiency, Adequacy, Yield (kg/ha), Yield (kg/m 3 ), Yield (kg/m 3 ) of Eto and
Crop yield ratio observed during 2013 to 2019. The indicators were assessed in two groups
viz., RS1 and RS2 where RS1 comprised of (i) Equity, (ii) Uniformity, (iii) Irrigation, (iv)
Over-all consumed ratio/Efficiency, (v) Adequacy, (vi) Yield and (vii) Crop yield ratio, while
RS2 comprised of (i) Gross area, (ii) Volume of water, (iii) Command area, (iv) Total Volume
of water, (v) Water demand, (vi) Rf, (vii) Dp, (viii) Area and (ix) Research station yield. Based
on RS1 group of indicators, Nellore was superior with best performance for all indicators
having lowest rank sum of 14. Kurnool command was the 2 nd best with rank sum of 17, while
Kadapa and Chittoor had a rank sum of 28 and 31 respectively. Based on RS2 group, Chittoor
was superior for all indicators with minimum rank sum of 14, followed by Nellore with 16,
Kurnool with 19 and Kadapa with rank sum of 20. When we considered both groups, Nellore
was superior with minimum rank sum of 30, followed by Kurnool, Chittoor and Kadapa with
rank sum of 36, 45 and 48 respectively in the TGP command.
