Effect of different irrigation intervals on growth of canola (Brassica napus L.) under different salinity levels

Effect of different irrigation intervals on the growth of canola cv. Oscar under saline water irrigation of different sea salt concentrations was investigated. Plants were subjected to control (non-saline), 0.4 (EC 4.5 dS.m(-1)) and 0.6% (EC 6.5 dS.m(-1)) of sea salt concentrations. Vegetative growth was recorded in terms of plant height, number of leaves and branches, fresh and dry shoot biomass per plant, while reproductive growth was noted in terms of number of flowers and siliquae per plant; siliquae weight; seed number and weight per siliquae; seed number and weight per plant: Plant growth on vegetative as well as reproductive phases was proportionately inhibited with respect to increasing salinity in irrigation water. Vegetative and reproductive growth of the plants was much reduced under 6 days irrigation interval as compared to 2 or 4 days irrigation interval under non-saline as well as saline water irrigation.
