EFFECT OF PLANTING DATE AND SALICYLIC ACID ON SOME INDICATORS OF VEGETATIVE GROWTH OF MUNG BEAN

A field experiment was carried out 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 Vegetation and its relationship to the growth of the mung crop. Where the experiment was carried out according to the design of randomized sectors in the order of the hardship plates with three replicates and two factors, the first factor representing the main plates and including four planting dates, 3/15, 4/1, 4/15 and 5/1, while the second factor representing the secondary plates contains four spray concentrations of acid Salicylic acid is 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, where the first date has a significant impact. The results were significant between planting dates, where the first date has a considerable influence of 3/15 in most growth traits such as the content of chlorophyll in the plant and the plant's leaf area, while the fourth date 1/5 had a significant effect on some characteristics such as plant height. In contrast, the results showed different significant effects of salicylic acid spray concentrations, where the concentration of 150 mg exceeded.L-1 in the plant height only.
