Cultivars Cardinal (V2), Chamak (V3) and Heera (V4) together formed a
group which were statistically identical (Table 2) in prducing dry weight of haulm/
plot. Binella (V1) produced the lowest (578.67gm) and Cardinal (V2) produced the
highest (696.5gm) dry weight of haulm/plot.
There were no significant variations among the interaction effects
between different irrigation regimes and potato cultivars (Table 3). However, the
highest (930.0gm) dry weight of haulm was obtained in I4 V3 and the lowest
(410.0gm) in I0 V1 treatments.
Yields of different potato cultivars as a function of seasonal water use
under different irrigation regimes are shown in Fig.3
