Effect of Foliar Spray with Nano-NPK Fertilizer and Yeast Extract on Growth of Orange (C. sinensis L. Osb.) Washington Navel Variety
Year: 2023
Type: conference-paper
Abstract: The factorial experiment was conducted in the Department of Horticulture and Landscape Gardening Design, College of Agricultural Engineering Sciences, University of Baghdad, Iraq through the growing season 2020 to investigate the vegetative growth response of navel orange seedlings grafted on the Citrus stocks to the spraying with balanced Nano-NPK (20-20-20) at four concentrations of (0,1,2 and 3) g. l-1 and yeast extract the following concentrations (0, 1.5, 3 and 4.5) g.l-1. The results in the two seasons showed a superiority effects of the interaction treatments at the highest concentrations of both of Nano-Fertilizer and yeast extract which it reached to the characters plant high, stem diameter, leaves number, leaf area, leaves area, branches number and chlorophyll (26.253cm.seedling-1,1.6867 mm.seedling-1,42.80leaf.seedling-1,33.267cm2.leaf-1,46.25cm2.seedling-1,8.8067 branch.seedling-1 and 273.93 mg.100g-1fw) in the first season and (27.233cm.seedling-1,2.41 mm.seedling-1, 54.67leaf.seedling-1,34.400 cm2.leaf1-,53.40 cm2.seedling-8.8073 branch.seedling-1 and 268.0mg.100 g-1 fw) in the second season for the studied characters respectively. Also, the interaction treatment (N3Y3) at the highest level of both of Nano-NPK and yeast extract showed the best results in the percentage of dry matter, N, P and K leaves content while the control treatment was the least for all the studied characters.
