Impact of Organic and Inorganic Fertilization on The Growth Characteristics of Superior Grape Vines

This investigation was carried out over two successive growing periods (2020/2021 and 2021/2022) on Superior seedless grapevines to examine the impact of organic, mineral, and biofertilization methods on the growth of Superior seedless grapevines. It was evident that the compost and/or compost tea treatment produced good superior seedless grapevines vegetative growth traits (average shoot length, leaf area, cane thickness, and pruning weight) with the best values when they applied together (compost + compost tea). All vegetative growth traits were affected by mineral and bio fertilization in both seasons. The treatment of (Min-NK + bio- P) produced the tallest shoots, biggest leaf area, thickest cane thickness, and heaviest pruning weight. It could be concluded that the treatments of (compost + compost tea) plus (Min- NK + bio-P) recorded the best results for growth development of Superior seedless grapevines.
