تأثير التغذية الورقية بالبورون والثيامين في نمو وحاصل الماش

Abstract

Two field experiment were carried out in the Sufiya area of Ramadi, Anbar province, that located on 43.35 E Longitude and 33.45 N Latitude during spring and autumn seasons of 2018 and at a height of 49 m above sea level, in muddy soil, in order to know the effect of spraying of four concentrations of thiamine (0, 150, 300, 450) mg.L-1 and boron (0, 25, 50, 75) mg.L-1 in the growth characteristics, yield and quality of the Vigna radiata L. The experiment was conducted as Factorial experiment arrangment in R.C.B.D with three replications. Results showed: 1- The foliar of thiamine (Vit. B1) affected significantly in all studied traits, the concentration 450 mg / L gave the highest average of plant height, number of branches per plant, leaf area (713.9 and 726.5 cm2) and number of corns in plant (44.07 and 45.92 corn) Fertility ratio and number of seeds in corn and seeds yield (2669 and 25.87%) and protein (278.6 and 279.9 kg.hecter-1) for the two seasons respectively, While the same concentration gave the lowest average for the number of days from planting to 50% flowering and the number of days from planting to maturity, while the concentration 300 mg/L gave the highest average concentration Boron in leaves and weighing 100 seeds. 2- Concentration 75 mg. L of foliar Boron record the highest average for the number of branches in the plant and leaf area (601.6 and 610.9 cm 2) and the concentration of boron in the leaves and the number of corns in the plant (36.78 and 38.56 corn.plants-1) and number of seeds in corn and seed yield in autumn season (964.0 kg-1), harvest index, protein ratio (25.62 B and 24.99%), and protein yield (2339.2 and 228.6 kg.e.-1) for the seasons respectively. While the same concentration gave the lowest average for number of days from planting to 50% flowering and the number of days from planting to maturity, while the concentration of 50 mg. L-1 was gave the highest average weight of 100 seeds. 3- Effect of interaction between concentrations of thiamin and boron significantly in leaf area and the number of days from planting to 50% flowering in the autumn season and the number of corns in the plant in the autumn season also and the weight of 100 seeds.
