TAILIEUCHUNG - Effect of pre harvest spray of ZnSO4, KNo3 and NAA on growth, yield and quality of Ber (Zizyphus mauritiana Lamk.) cv. seb under malwa plateau conditions

The experiment was conducted at the Instructional cum Research Fruit Orchard, College of Horticulture, Mandsaur (.), Department of Fruit Science, Rajmata Vijayaraje Scindia Krishi Vishwa Vidyalaya, Gwalior (.). The experiment comprised 13 treatments of foliar spray of ZnSO4, KNO3 and NAA and control, first foliar spray of growth regulator and micronutrient (ZnSo4 and KNO3) on crop was done on 15th October, 2014 and same spray was repeated after 30 days of the first spray with three replications and data analyzed in Randomized Block Design (RBD). The treatments which were compared among them and found best during the period of experiment are given below: Growth Parameters: Maximum Shoot diameter ( mm), Shoot length (204 cm), Physical parameters: Maximum Fruit length ( cm), Fruit diameter ( cm), Fruit volume ( ml), Stone weight ( g), Pulp weight ( g), Specific gravity (), Bio - chemical parameters: Maximum TSS ( 0Brix), minimum Acidity ( %), Ascorbic acid ( mg/100g of pulp), Reducing sugar ( %), Total sugars ( %), Non-reducing sugar ( %) and Yield parameters: Maximum Number () of fruits / tree, Fruit weight ( g), Yield / tree ( kg) was found in treatment T12 (NAA 60 ppm + KNO3 + ZnSO4 ) and minimum was found in control respectively. | Effect of pre harvest spray of ZnSO4, KNo3 and NAA on growth, yield and quality of Ber (Zizyphus mauritiana Lamk.) cv. seb under malwa plateau conditions
