“fertilization of pea plants with 100 kg N/fed. combined with foliar application of AsA at 400 mg L-1 followed by 80 kg N/fed. with 400 mg L-1 of AsA gave significant increases for the traits of plant vegetative growth (plant height and fresh weight, branches and leaves number/plant, leaves fresh weight, leaves area/plant and partially leaves dry matter percentage), leaves chemical composition (N, P and K percentages and chlorophyll a, b and carotenoids contents), pods and seeds yield components (number and fresh weight of green pods/plant, green pods yield/fed., 100 seeds fresh weight and green seeds yield/fed.), seeds quality (Vit. C, TSS, total carbohydrates, crude protein, N, P, and K contents) and moderate values for both seeds nitrate (NO3) and dry matter percentage of pea compared with control treatment (60 kg N/fed. only), without significant differences between two interaction treatments in both seasons.”
