Abstract

his study aims at investigating the effect of organic growth stimulator on growth and yield of rapeseed (Dalgan cultivar) under drought in University of Zabol (Chahnime) during 2017 as a split plot experiment, based on RCBD with three replications. The treatments include irrigation cut off levels, based on the phenological growth stages (Sylvester-Bradley encoding system): I1 = control (complete irrigation), I2 = irrigation up to growth rate code 2. 20 (twenty internally identified), and I3 = irrigation to growth rate code 5. 9 (all pods are more than 2 cm long), with the subsidiary factor being consisted of four levels of fertilizer: F1 = control (pure water solution), F2 = Hamoon Green 1 liter at 10 liter + calcium, F3 = Hamoon Green 1 Liter at 20 liter + calcium, and F4 = Hamoon Green 1 liter at 30 liter + Calcium. Results show that I2 has significantly decreased plant height, stem diameter, number of pods, number of seeds per pod, 1000-seed weight, grain and biological yield, and oil percentage, while F2 has increased the abovementioned traits, except for the percentage of oil. Interaction effects show that the highest amount of chlorophyll a, b, total, carotenoid, selenium, and calcium content of grain belong to I1F2, while the highest amount of proline has been observed in I2F2. Also, the highest of these traits belongs to F2. Generally, spraying the organic growth stimulator can moderate the harmful effects of drought stress in rapeseed, improving the seed yield by 27%.
