| ABSTRACT A field experiment was conducted at the experimental research farm of Al-Azhar University in Assiut during the 2022/2023 and 2023/2024 seasons to study the effect of plant density at three densities (33, 22, and 17 plants/m²) and three concentrations of ascorbic acid (0, 2, and 4 ml/L) on the yield, its components, and quality of chickpea seeds. The experiment was designed as a split-plot in a randomized complete block design for main plots with three replicates, where main plots were allocated to the three plant densities and subplots allocated to the ascorbic acid concentrations. The results of this study showed that planting distance had a significant effect on all measured traits (plant height, number of branches and pods per plant, 100-seed weight, seed yield per plant, total seed yield in kg/feddan, straw yield in tons/feddan, and seed protein content) in both growing seasons. The highest values for most traits were recorded at a plant density of 33 plants/m², except for the number of branches per plant, which peaked at a plant density of 17 plants/m² in both experimental seasons. Foliar application of ascorbic acid at high concentration (4 ml/L) resulted in significant and increasing improvements in all studied traits in the first and second seasons of this study. This research study recommends applying a plant density of 33 plants/m² with foliar spraying with ascorbic acid at a rate of 4 ml/L to improve chickpea productivity under the prevailing conditions of the research area. | ||||
