EFFECT OF PLANTING DATES AND FOLIAR APPLICATION OF SALICYLIC ACID ON THE GROWTH AND YIELD OF MUNG BEAN

A field experiment was conducted during the summer season of 2021 in a field belonging to the Department of Field Crops in Ibn Al-Bitar Preparatory School in Al-Hussainiya District, Holy Karbala Governorate, to know the best date for planting the marrow crop and determining the best concentration of salicylic acid that suits the crop in resisting the stresses, it is exposed to improve the qualities of happening in the mash crop. Where the experiment was carried out according to the Randomized complete block design (RCBD) in the order of the hardship plates with three replicates and two factors, the first factor representing the main plates including four planting dates, 3/15, 4/ 1, 4/15 and 5/1, while the second factor representing the secondary plates includes four spray concentrations of salicylic acid 0, 50, 100 and 150 mg.l-1 during the flowering period for each planting date. The results showed a significant effect between planting dates, as the first date has a significant impact. The results were substantial between planting dates, where the first date has a considerable influence of 3/15 in mostof the qualities obtained, such as the number of pods, the number of seeds in a pod, and the total yield of the plant. At the same time, the results showed different significant effects of salicylic acid spray concentrations, where the concentration of 150 mg.L-1 significantly exceeded in some traits, such as the number of pods per plant and the total yield.
