Methodology
Indicator values of yield attained in different districts in TGP command during 2013 to 2019
Ranking of different parameters in four districts
Ranks were assigned to different parameters for their mean values over years for assessing their
superiority in different districts. The rank sums of parameters are given in Table. The rank
sums were separately derived for 2 categories of parameters, viz., RS1 and RS2. RS1 comprised
of (i) Equity, (ii) Uniformity, (iii) Irrigation, (iv) Overall consumed ratio/Efficiency, (v)
Adequacy, (vi) Yield and (vii) Crop yield ratio. 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 (Bos et al.,1994). Rank sums of RS1 indicated that
Nellore was superior with minimum rank sum of 14, followed by Kurnool with rank sum of
17, Kadapa with rank sum of 28, while Chittoor attained maximum rank sum of 31. Rank sums
of RS2 indicated that Chittoor was superior with minimum rank sum of 14, followed by Nellore
with rank sum of 16, Kurnool with rank sum of 19 and Kadapa with maximum rank sum of 20.
The over-all rank sum indicated that Nellore was superior with minimum rank sum of 30,
followed by Kurnool with rank sum of 36, Chittoor with rank sum of 45 and Kadapa with rank
sum of 48 in the TGP command.
