Role of Irrigation with fish pond water and Zeolite addition on Growth and Production of two hybrids of Cabbage plant Brassica oleracea var. Capitata

Abstract

The study was conducted during the winter agricultural season of 2021-2022 in a field located in the Najaf province to study the effect to three factors on growth and production of to two hybrids of cabbage plant. The experiment included three factors. The first factor was two hybrids of the cabbage plant including the red Cabbage hybrid (Glope Star F1) and the white Cabbage hybrid (Cabbage Liza F1). The second factor was irrigation with three concentrations of with fish pond water including 0, 50, and 100%. The third factor was the addition of three zeolite levels: which were 0, 10,and 20 g plant^-1. The results showed that the white cabbage hybrid was significantly superior in terms of average of head weight, recording 1204.40 g and the total yield of 40.15 ton ha^-1 compared to the red cabbage hybrid. The results also showed that irrigation with fish pond water at a concentration of 100% was superior in increasing both plant height and the leaf area reaching 22.31cm and 162.43 cm² leaf^-1 compared to untreated plants. The results showed that adding zeolite at the level of 20 g plant^-1 was significantly superior in giving the highest average of dry weight of the shoot reaching to 717.10 g plant^-1. The results documented the triple interactions between the white cabbage hybrid, irrigation with 100% fish pond water, and the addition of zeolite at a level of 20g. increases both plant height to 25.03 cm and the leaf area to 168.63 cm²  Leaf^-1. The interactions recorded 958.90 g of dry weight of the shoot, 19.70 cm diameter of the head, 1685 g the average weight of the head, and 56.18 ton ha^-1 total yield.
