Effect of foliar spray of urea and micro-nutrients on yield and quality of acid lime (Citrus aurantifolia Swingle) cv. Kagzi lime

Abstract

An experiment was conducted on healthy, uniform 12-year-old trees of Acid lime (Citrus aurantifolia swingle) cv. Kagzi lime at Fruit Research Farm, Department of Fruit Science at KNK College of Horticulture, and Mandsaur during 2016-2017. The experiment was conducted in Randomized Block Design with three replications. There were three levels of Urea, Zinc Sulphate and Borax i.e., Urea (0.5%, 1.0% and 1.5%), ZnSO4 (0.3%, 0.4% and 0.5%) and Borax (0.4%, 0.5% and 0.6%) and with three levels of combination (Urea, Borax and ZnSO4) Urea 0.5% +Borax 0.4% +ZnSO4 0.3%, Urea 1.5% +Borax 0.5% +ZnSO4 0.4% and Urea 1.5% +Borax 0.6% +ZnSO4 0.5% were applied and compared with control. Maximum Number of fruits per plant, fruit weight and fruit yield was recorded with foliar spray of T12 (Urea 1.5% +Borax 0.6% +ZnSO4 0.5). Further significantly increased quality characteristics like Maximum TSS, ascorbic acid, TSS: acid ratio were also recorded with foliar spray of T12 (Urea 1.5% +Borax 0.6% + ZnSO4 0.5%).
