| dc.description.abstract | The present investigation entitled “Foliar spray of calcium chloride and boric acid for improving fruit yield, quality and shelf-life of guava (Psidium guajava L.) cv. Pant Prabhat” was conducted at The Horticultural Research Centre Patharchatta, G. B. Pant University of Agriculture and Technology Pantnagar, Uttarakhand in the year 2015-16. The objectives of the present investigation were to evaluate the effect of foliar sprays of calcium chloride and boric acid either alone or in combination on yield, quality and shelf life of guava cv. Pant Prabhat. The experiment was comprised of 9 treatments viz., T1-(calcium chloride @ 0.2%), T2-(calcium chloride @ 0.4%), T3-(boric acid @ 0.1%), T4-(boric acid @ 0.2%), T5-(calcium chloride @ 0.2% + boric acid @ 0.1%), T6-(calcium chloride @ 0.2% + boric acid @ 0.2%), T7-(calcium chloride @ 0.4% + boric acid @ 0.1%), T8- (calcium chloride @ 0.4% + boric acid @ 0.2%) and T9-(control), with 3 replications. The experiment conducted in randomized block design. Maximum yield (28.40 kg/tree), total sugars (7.63%), ascorbic acid (254.83mg/100g), TSS (11.74 ºBrix), leaf nitrogen content (2.11 %), calcium content (2.23%) and boron content (63.57 ppm) was recorded in T8 (calcium chloride @ 0.4% + boric acid @ 0.2%). Maximum leaf phosphorus content (0.26%) in T2 (calcium chloride @ 0.4%). Maximum leaf potassium content (1.09%) in T7 (calcium chloride @ 0.4% + boric acid @ 0.1%), while acidity (0.23%) was reduced significantly in T4 (boric acid @ 0.2%). Physiological loss in weight was minimum under T2 (calcium chloride @ 0.4%) and overall acceptability of fruits in storage up to 8 days was maximum under T8 (calcium chloride @ 0.4% + boric acid @ 0.2%). Result of present investigation revealed that foliar application of calcium chloride combination with boric acid was found to be superior for improving yield, quality and shelf life of guava fruits. | en_US |
