Effects of irrigation cutoff at seed formation stage on seed yield and germination indices of sugar beet seed

One of the most important goals of sugar beet cultivation is to achieve high seedling emergence and establishment under water deficit conditions. In this experiment irrigation of the seed bearing plants was cutoff in four periods of 750, 1000, 1250 and 1500 GDD after schtechlings were planted and th...
