Effect Of Calcium and Boron on Growth, Yield and Quality of Pomegranate (Punica granatum L. )

A field experiment was conducted to study the effect of foliar application of calcium and boron on vegetative growth, flowering, fruiting and fruit quality of young pomegranate plants cv. BHAGWA. The experiment was set under Randomized Block Design with application of calcium (3 and 5%), boron (0.25 and 0.5%) and their combinations with three replications. The experiment showed that combined application (T₆) of calcium (3%) and boron (0.25%) increased plant height at higher rate as compared to their sole application and control. It (T₆) also produced more number of secondary branches at early stage but, under T₇ (calcium 3% and boron 0.5%) at later stages of growth. Although, it was a young orchard, however, flower production was higher under T₆ followed by T₇ compared to others which was reflected on fruit yield and fruit yield was the highest (359.5 kg/ha) under T₆ followed by T₇. Fruit weight and fruit size was recorded maximum (77.0 g, 6.1 cm length, 6.00 cm diameter) under T₇. But, other quality parameters like fruit volume (70 ml), specific gravity (1.10 g/cc), TSS (12.57 °B) and sugars (6.66 % Total sugars, 4.73 % reducing sugar) were very good under T₆. It is concluded that the combined application of calcium (3%) and boron (0.25%) (T₆) could be practiced for good growth, yield and quality fruits of pomegranate.
