Effect and economic feasibility of preharvest spray of Calcium nitrate, Boric acid and Zinc sulphate on yield attributing characters of Nagpur mandarin (Citrus reticulata Blanco.)

An investigation was carried out during 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 and Boric acid and and Zinc sulphate and 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 T treatment combination calcium nitrate boric acid Zinc sulphate over control Further T treatment combination calcium nitrate boric acid Zinc sulphate has also significantly increased number of segments per fruit and reduced number of seeds per fruit over control
