The effect of spraying nutrient solution (Growmore) and benzyl adenine on some vegetative traits of sour orange seedling

Abstract

The experiment was carried out in the  lath house  of the College of Agriculture, Al-Qasim Green University, during the growing season 2022-2023, to study the effect of foliar spraying with the nutrient solution (Grow more) and the growth regulator benzoyl adenine( BA ) on the vegetative growth of 6-month-old  sour orange seedlings. The experiment included spraying with Grow more nutrient solution in three concentrations (0, 1 and 2) gm. l ^-1 and benzyl adenine in three concentrations (0, 50 and 100) mg .l ^-1. The study was carried out as a factorial experiment with two factors according to the randomized complete block design (RCBD) with three replications for each treatment. The results can be summarized as follows: The study factors affected all the studied traits, as it gave the highest values for average plant height, stem diameter, number of leaves, chlorophyll content in the leaf and number of branches, when the two factors overlapped with Grow more nutrient solution and benzyl adenine (BA) at a concentration of 2 g. l ^-1 and 100 mg.l ^-1 for both agents, respectively, it recorded 73.14 cm, 0.75 cm, 77.14 leaf. plant ^-1, 70.63 spad and 5.37 branch. plant ^-1, respectively.
