Studies on effects of organic traditional leather waste on soil properties, quality and yield of selected crop

The utilization of organic amendments in agriculture has gained significant attention due to their potential to improve soil fertility, enhance crop quality, and promote sustainable farming practices. This study investigates the effects of organic traditional leather waste on soil properties, quality, and yield of grapes (Vitis vinifera). The research was conducted in Pimpalgaon Baswant, Nashik District, Maharashtra, India, using a randomized complete block design (RCBD) with three treatment categories: A1 (Solid + Water in 15 DIAP, Drenching), A2 (Solid + Water in 30 DIAP, Drenching), and B (Only Solid in 15 DIAP, Sub-Soil Application). Soil samples were analyzed for physicochemical properties, nutrient content, and microbial activity before and after organic waste application. Plant growth parameters, biochemical composition of leaves, and fruit yield quality were assessed. The results indicate that organic traditional leather waste significantly improved soil fertility, with notable increases in organic carbon (1.3% at 600 g/Plant), nitrogen (298 Kg/ha), phosphorus (17.667 Kg/ha), and potassium (245 Kg/ha). Morphological parameters such as shoot length (168.8 cm at 600 g/Plant), cane diameter, and internodal distance showed significant improvements compared to control. Biochemical analysis revealed increased chlorophyll (1.038 mg/g), protein (0.632 mg/g), and reducing sugar (0.514 mg/g) content in treated plants. Yield parameters improved significantly, with the highest TSS (24.76° Brix) and yield per hectare (53.09 tonnes at 100 g/Plant) observed in sub-soil treatments. These findings suggest that organic traditional leather waste enhances soil health, improves crop productivity, and can serve as an effective alternative to synthetic fertilizers, contributing to sustainable agricultural practices. publihed by the Journal of Biodiversity and Environmental Sciences (JBES)
