Influence of Bio, Nano and Conventional Fertilizers on the Growth Features of a French Black Grape Variety

Abstract

A French black grape cultivar was tested in a Babylon province/Al-Hamzah Al-Gharbi district private orchard using the Randomized Complete Block Design (RCBD) three-factor factorial configuration. The first is applying biofertilizer, which includes Bacillus megaterium and Mycorrhiza glomus fungus, to the soil at two concentrations (0 and 10 ml L-1), the second is applying liquid organic fertilizer at three concentrations (0, 15, and 30 ml L-1), and the third is applying organic fertilizer via foliar spraying. Nanofluid concentrations will be 0.1 and 3 ml L-1 in 2020 and 2021. Most biofertilization vegetative growth metrics showed that excelled in the leaf area per cluster was 9.42 cm cluster-1 in both seasons, while organic nano-fertilization at 3 ml L-1 boosted most vegetative growth indicators. Most vegetative development metrics responded significantly to bidirectional research parameter interactions, the bi-interaction between organic nano-fertilizer at a concentration of 3 ml L-1 and organic fertilizer at a concentration of 30 ml L-1 significantly affected the leaf area, the total leaf area, and the leaves’ content of total chlorophyll. 10 ml L-1 biofertilizer and 30 ml L-1 organic fertilizer achieved the heist values in leaf area, total leaf area, and leaf content. The interaction between the bio fertilizer at a dosage of 10 ml L-1 and the organic nano fertilizer at a concentration of 3 ml L-1 considerably altered the content of total chlorophyll in leaves.
