Abstract
A pot culture study was conducted on growth and yield performance of two wheat genotypes (Pato and SA RC-6) in response to waterlogging under non-saline (2.96 d Sm') and saline (15 d Srn") soil conditions in a wire house. Desired salinity of 15 d Sm'l was developed by mixing required amount ofNaCI salt in the soil before filling the pots. The treatments within each set comprised of watcrlogging imposed for a period of 21 days at different growth stages, i.e., tillering. booting and grain tilling alone or in different combinations. At maturity, data regarding grain yield and different yield components were recorded. The maximum reduction in grain yield was observed when waterlogging was imposed at tillering and then at grain tilling stage followed by the decrease due to a spell of waterlogging at grain tilling stage alone and at booting stage alone, respectively, Also. salinity increased the effect ofwaterlogging at all growth stages, but the trend remained the same as was observed under non-saline soil conditions.
