values of pumpkin to water deficit for the entire growing season
were 0.92 and 1.27 in 2013 and 2014, respectively. When values
are combined for both the years, the coefficient of determination
(r2) was 0.92, and the relationship was statistically significant at
a level of P < 0.01. As illustrated in Fig. 5, ky was 1.08 when the
experimental years were considered together. For ky > 1 condition,
the crop response is very sensitive to water deficit with proportional
reduction in the yield when water use is reduced due to
