بررسی اثر شوری آب آبیاری بر خصوصیات کمی سیاهدانه

Black cumin due to high rates of oil ,essential oil and different therapeutic effects, is considered as medicinal and oil seed plant. In order to investigate the effects of water salinity of irrigation (0, 3/5 , 5 dS/m) on crop characteristics of black cumin (Nigella sativa L.), a field experiment was performed in a completely block design with 3 replications in agricultural and natural resources center of Esfahan in 2012-2013. In this study: plant height, number of flowers per plant, seeds per plant, seeds per capsule, capsules per plant, infertility seeds per capsule, follicles per capsule, seeds in a follicle, 1000 seed weight, seed yield, biological yield and harvest index were measured. Data analysis showed that the effect of salt water salinity on most of the measured traits were significant and by increasing salt concentration, all traits were significantly reduced.
