SUPPRESSION OF IRRIGATION WATER DEFICIT STRESS AFFECTING SOYBEAN PRODUCTION | Journal of Global...

Droughts have occurred frequently throughout Egyptian history. As a result, the drought in the agricultural sector is a critical subject to investigate. As a result, a field experiment was conducted to assess the effects of three irrigation intervals [irrigation every 7, 9, and 11 days], soil addition of some conditioners [control (without), compost, zeolite, and biochar] as subplots, and foliar application of magnesium silicate (sprayed or not) as sub-subplots on soybean plant performance and productivity, as well as soil fertility after harvest. The main findings revealed that soybean plants irrigated every 9 and 11 days had low growth and production criteria, but soybean plants irrigated every 7 days had the highest values of both growth and yield criteria (e.g., plant height, fresh and dry weights, and chlorophyll content) ( i.e., pod weight plant-1, seed weight plant-1, stover weight plant-1, 1000 seed weight, seed and stover yield). All tested soil supplements enhanced all analysed growth and production criteria when compared to similar soybean plants grown on unamended soil, with compost being the most effective amendment, followed by zeolite, and most recently, biochar conditioner. In comparison to the similar soybean plants cultivated without foliar application, foliar application of magnesium silicate increased all evaluated growth and production metrics. In addition, all of the soil amendments evaluated differed in their favourable influence on soil fertility as well as their critical function in irrigation water conservation.
