Effect of ground addition and foliar spraying of bio -fertilizer on some vegetative growth characteristics of local lemon (Citrus lemon L.) Saplings

Abstract

This study was carried out in the lath house of the Department of Biology -College of Education for Pure Sciences – University of Anbar, during the autumn season (2020) with the aim of studying the effect of soil fertilization and foliar application of (Bio health) bio fertilizer on some of the vegetative growth characteristics of local lemon saplings. A factorial experiment with two-factors experiment was carried out according to the randomized complete block design (RCBD), included 16 treatments, with four replicates, the first factor (A) was the soil fertilization with at four concentrations of 0, 2, 4 and 6 g.L-1, the second factor (B) was foliar application with at four concentrations 0, 1, 2 and 3 g.L-1, the results showed the superiority of the treatment of soil fertilization with a concentration of 6 g.L-1 and the foliar application of 3 g.L-1, and the interaction between them was significant in the characteristics of scion diameter, leaves content of relative chlorophyll, leaf area and leaves area, as for the treatment, Foliar application with a concentration of 2 g.L-1 and 3 g.L-1 showed a significant increase in the characteristic of plat height and rootstock diameter respectively, while the interaction between soil fertilization and foliar application of 2 g.L-1 showed the best result in the characteristic of plant height, while the interaction between the soil fertilization treatments 1 g.L-1 and foliar application at a concentration of 2 g.L-1 showed the best diameter of rootstock.
