| Abstract | ||||
| Enhancing land productivity through efficient resource utilization is a core objective in sustainable agriculture. Intercropping and improved sowing techniques are widely recognized for their potential to optimize crop performance and maximize yields. Integrating winter wheat with Egyptian clover has demonstrated positive effects on photosynthetic activity and yield stability. Intercropping legumes with cereals offers a promising solution, as legumes can fix atmospheric nitrogen biologically, enriching the soil for current or subsequent crops. This study evaluated the impact of different sowing methods and intercropping ratios on the performance of wheat and Egyptian clover under field conditions across two consecutive seasons (2021/2022 and 2022/2023). A total of eight treatment combinations were assessed in a strip-plot layout within a randomized complete block design (RCBD) with three replications. Two sowing techniques broadcasting and row planting were tested alongside four intercropping arrangements involving wheat (cv. Gemmeizah 11) and Egyptian clover (var. Fahl): sole cropping of either species, and mixed cropping at 75:25, 50:50, and 25:75 ratios. Findings indicated that intercropping had no adverse effect on wheat grain yield. Row planting, particularly at a 50:50 ratio, significantly improved yield components and economic returns. These results support the adoption of intercropping systems, especially with row sowing, as a viable strategy for enhancing productivity and sustainability in wheat-based cropping systems. Plant height, thousand grain weight, biological yield, grian yield, and protin % were strongly correlated and positively with PC1 but spike length, and no. of spikes/m2 were neigaitve strong corrleation in PC2. | ||||
