Effect of Some Organic Manures Tea on Superior Grapevine Yield and Physio-Chemical Quality

In contemporary agriculture, there is a pursuit for effective, sustainable, and eco-friendly alternatives that can enhance and preserve soil quality and fertility in the long term. The utilization of organic waste as fertilizer represents a significant approach toward achieving sustainable production. Recently, the application of innovative products derived from compost, such as compost tea and chicken manure tea, are gaining traction owing to their beneficial impacts on crops. This perspective aims to provide a contemporary assessment of the impact of substituting N-mineral fertilization with organic manure in agriculture. This research was conducted over the 2022 and 2023 seasons to assess the impact of various organic fertilization sources (compost tea and chicken manure tea) as a partial replacement for nitrogen minerals, and their influence on yield, and the physico-chemical quality of Superior grapevines compared with the full dose of N-mineral. Experiment was set at a private farm in Talla village, Minia Governorate. However, Increasing the nitrogen replaced ratio up to 40% (using 60% compost tea + 60% chicken manure tea) resulted a significant reduced in all yield and phyisico-chemical quality parameterizes. Superior grapevines productivity and quality significantly enhanced as a result of increasing the ratio of mineral N replaced by compost and chicken manure tea. On the opposite side, increasing the ratio of mineral N replacement till to 60% (using 40% compost tea + 40% chicken manure tea) caused a highest significant increase in yield (kg) and cluster parameters, physio-chemical berry quality and reduction in shot berry and total acidity. So, this treatment was the best in achieving the highest yield of Superior grapevines.
