Effect of Adding Poultry Manure and Spray with Foliar Nutrients on the Growth and Yield of Broccoli Brassica oleracea Var. Italica.

Abstract

Abstract The study was conducted in Al-Bu’itha research station -College of Agriculture - University of Anbar, during the growing season 2022 to find out the effect of poultry manure at levels (0, 100, 200 and 400 g plant−1) and spraying with Foliar nutrients at concentrations (0, 2, 4 and 6 ml L−1) on the growth and yield of broccoli, A factorial experiment was carried out according to the Randomized Complete Block Design (RCBD) with three replications. The results Showed That were significant differences when added poultry manure, as the treatment was superior to 400 g plant−1 in plant height 72.60cm, the total number of leaves 45.17 leaf plant−1, leaves area 127.64dm2 plant−1, stem diameter 36.94 mm, and the percentage of chlorophyll 83. 95 Spad, the weight of the main flower stalk 1.491 kg, plant−1, and the total weight of the main flower stalk is 47.94 tons ha−1. The interaction between the factors of the study, the treatment of adding organic fertilizer at a concentration of 400 g plant−1 and spraying with a nutrient solution at a concentration of 6 ml L−1 had a significant superiority in yield characteristics from the weight of the main flower stalk 1.781 kg plant−1, and the total weight of the main flower stalk 59, 41 tons ha−1.
