Abstract
The present investigation was conducted during 2015–16 on guava cv. Pant Prabhat having 9 treatments ofdifferent combinations of calcium and boron sprays made in 3 replications. The results obtained showed thatminimum physiological loss in weight (PLW) was found under T2 (calcium chloride @ 0.4%) treatment. Whereas, TSS (11.99oB), ascorbic acid (252.4 mg/100 g) and total sugars (7.51%) were found to be maximum in T8 (calciumchloride @ 0.4% + boric acid @ 0.2%) treatment and overall acceptability of fruits in storage up to six days wasalso found maximum under the same treatment. The findings of the present investigation revealed that thepre-harvest foliar application of calcium chloride and boric acid twice was an effective way for improvement offruit quality and shelf-life of guava. Calcium chloride (0.4%) and boric acid (0.2%) were found to be effective inincreasing quality, whereas, calcium chloride (0.4%) alone was effective for maintaining fruits under ambientstorage conditions for six days.
