Effect of Bio-Fertilizer and Banana Peel Extract on the Vegetative Traits and Yield of Carrot Plants

Abstract

The field experiment was conducted in the training extension farm in Al-Mahanawiya / Al-Musayyab district, 25 km northwest of Hilla city center / Babylon province. The seeds of the stinger carrot hybrid were planted during autumn season on October 3, 2021. To study the effect of adding biofertilizers and banana peel extract on the vegetative growth and yield of carrots. The experiment was designed according to a split plot-system using a randomized complete block design with three replications. The results of the experiment were statistically analyzed according to the method of analysis of variance and according to the significant differences between the treatments at the probability level of 0.05 using the least significant difference LSD. The results indicated that bio-fertilization had a significant effect on (percentage of dry matter in the vegetative total) and (Fulzyme) scored a significantly excelled in (number of leaves, relative content of chlorophyll, percentage of dry matter in the root, root length, root diameter, average root weight and total yield). Treatment with the organic extract of banana peels showed at the concentration of 40 ml. L-1significantly excelled in (plant height, number of leaves, percentage of dry matter in vegetative and percentage of dry matter in the root) and at a concentration of 20 ml. L-1 in (relative content of chlorophyll in leaves, root size, average weight of the root and total yield). The bi-interaction of the biofertilization treatment and the organic extract indicated significant differences, where the interaction of Fulzyme and concentration 40 ml.L-1 was significantly excelled in the percentage of dry matter in the vegetative and root (29.67% and 13.09%), respectively. As for the Biohealth interaction and the concentration of 40 ml.L-1, it significantly excelled in the plant height (25.26 cm). The interaction Fulzyme and concentration 20 ml.L-1 recorded the highest root volume and average root weight (135.8 cm3, 80.9 g), respectively, The interaction between Biohealth and concentration of 20 ml.L-1 recorded the highest total yield (12.73 tons. ha-1) while it was the lowest for all studied traits when the control treatment of both biofertilization and banana peel extract.
