Effect of Bio Fertilizer, Nano Organic Fertilizer and Non-Nano Organic Fertilizer on the Quantitative Traits of French Black Grape Cultivars

Abstract

A French black grape cultivar was tested in a private orchard in the Al-Hamzah Al-Gharbi region of Babylon province using the three-factor, three-replicate Randomized Complete Block Design (RCBD). Biofertilizers like Bacillus megaterium and Mycorrhiza glomus fungus are applied to the soil at a concentration of 0 and 10 ml L-1; liquid organic fertilizer is applied to the soil at concentrations of 0, 15, and 30 ml L-1; and finally, organic fertilizer is sprayed on the leaves of the plants. The nanofluid in two different concentrations (0.1 and 3 ml L-1) during the entire year (2021). Averages were compared using the statistical program GenStat and the least significant difference (L.S.D.) test at the level of probability 0.05. The experiment included one sector (18) of the cultivar’s vines, with a number of experimental units distributed randomly in three sectors, and the number of vines was (54) vines for the cultivar. Here is a quick rundown of the most relevant findings: The results revealed that biofertilization at a concentration of 10 ml L-1 had a significant influence on most quantitative features of the yield, leading to an increase in the overall yield, which peaked at 36.2 and 38.6 kg. Vine-1., While the average number of clusters increased to 51.6 and 53.9 per vine with the application of organic nano-fertilization at a concentration of 3 ml L-1, the highest value for total yield was attained at 37.0 kg vine-1. The organic fertilization at a concentration of 30 ml L-1 had a significant effect on most of the quantitative indicators, leading to an increase in the total yield as it gave the highest value of 36.6 and 37.5 kg vine-1.
