Abstract | ||||
This study aims to evaluate the effect of organic amendments and soil mulching on soil properties and soybean productivity grown under a drip irrigation system. The experiment was conducted at the Faculty of Agriculture farm (Demo) at Fayoum University, Egypt, located at 29°17′006″N and 30°54′055″E in the SI 2023 and SII 2024 seasons. Four soil amendment treatments were assessed, i.e., zero (control), 20 t ha-1 of compost (C), 10 t ha-1 of vermicompost (V) and a mixture of both 10 t ha-1 of compost + 5 t ha-1 of vermicompost (CV), and two organic soil mulching (SM) rates of rice straw (M0 and M1; zero and 8 t ha-1). The treatments were conducted using a randomized complete block arrangement (split-plot design) with three replicates. The results showed that the values of soil bulk density and hydraulic conductivity were significantly decreased by 5.56 and 10.98%, 12.35 and 31.44%, and 16.67 and 46.97% when applied to C, V, and CV, respectively, as compared with the control. On the other hand, there are significant increases in values of total porosity, water-holding pores, and useful pores by 0.43, 17.32, and 1.44%; 5.10, 26.45, and 5.66%; and 7.39, 33.19, and 8.28% when C, V, and CV are applied, respectively, as compared with the control. Soybean growth parameters and physiological attributes were significantly affected by the applied treatments. The application of CV+ SM8 significantly increased the values of weight 100 of seeds and seed and straw yield by 21.17, 6.11, and 24.29%, respectively, as compared with the control. It could be concluded that the combination of CV and SM8 led to an improvement in soil properties and the productivity of soybean plants. | ||||
