Abstract
An investigation was carried out during 2014-15 to study the effect of pre harvest spray of Calcium nitrate, Boric acid and Zinc sulphate on yield attributing characters of Nagpur mandarin. Various doses of Calcium nitrate (1.0%, 2.0% and 3.0%), Boric acid (0.2%, 0.4% and 0.6%) and Zinc sulphate (0.2%, 0.4% and 0.6%) were sprayed before harvesting. The maximum increase in yield attributing characters like diameter of fruit, fruit weight, fruit volume, fruit yield/plant, estimated(yield/ha), maximum gross return, highest net profit and reduced peel thickness was recorded with T27 treatment combination (calcium nitrate 3.0%+ boric acid 0.6%+ Zinc sulphate 0.6%) over control. Further, T24 treatment combination (calcium nitrate 3.0%+ boric acid 0.4%+ Zinc sulphate 0.6%) has also significantly increased number of segments per fruit, and reduced number of seeds per fruit over control.
