Effect of nano nitrogen and phosphorus on growth, yield and quality of ber, Ziziphus mauritiana Lam

An experiment was conducted at Agricultural Research Station, Mandor, Jodhpur (Raj.) to find out the effects of nano nitrogen and phosphorus fertilizers on growth, yield quality ber using Factorial Randomized Block Design with 5 replications from October 2021 March 2022. The result showed that maximum rise (6.45 %) in plant height (79.17 cm), number primary branches (14.72), secondary (22.09), chlorophyll contents (55.34 SPAD value), fruit volume (20.63cm3), specific gravity (0.95), length harvest (3.42 diameter (3.16 pulp thickness (12.56 mm), weight (15.79 g), pulp: stone ratio (19.20), setting (6.92 %), average (18.00 yield/ tree (64.57 kg), ascorbic acid (65.75 mg/100g pulp), total soluble solid (15.77°Brix), sugar (9.20 reducing (4.83 non-reducing (4.37 pH (5.50) whereas minimum (0.82 g) drop (49.38 recorded application @ 2 ml/ litter water + spray over control.
