Effect of Salicylic and Ascorbic acid on Growth, Green yield of two Broad bean Cultivars (Vicia faba L.)

Article History: Received: 01/03/2018 Accepted: 14/08/2018 Published: 28/10 /2018 The experiment was conducted in the vegetable research farm of Horticulture Department, College of Agriculture/ University of DohukIraq, interior the plan of Broad bean crop production during the growing season of 2016-2017, to investigate the effects of two Cultivars (Aguadolce & Elisa), Salicylic acid and Ascorbic acid at concentration (0, 100 & 150 g.L -1 ) on growth, green yield and green seed yield of Broad bean (Vicia faba.). Results showed that the cultivars had no affect on vegetative characters. The Elisa cultivar had significant increase on some majority green yield and seed yield characters (Pod Yield g. plant -1 , Total Yield ton. donum -1 , No. of seed per pod, seed weight g and weight of 100 seed g). While Aguadolce cultivar had significant increase in (pod length cm). There were no significant effect of cultivars on (No. of pods per plant pod.plant -1 , Pods weight g, No of seeds per plant, green seed yield g.plant -1 and total seed yield ton. donum -1 ). But ascorbic acid significant increased (No. of pods per plant pod.plant -1 , No. of seed per pod, seed weight g, weight of 100 seed g Green Seed yield g.plant -1 and total seed yield ton. donum -1 ) ), While treating of broad bean plant with salicylic acid especially (100g.L -1 ) led to significant increases (pods weight g, No. of branches per plant, Pods weight g, Pod Yield g. plant -1 , Total Yield ton. donum -1 , No. of seed per pod, seed weight g, weight of 100 seed g, Green Seed yield g.plant -1 and total seed yield ton. donum -1 ).
