Abstract

An investigation was conducted at Horticulture Research Farm, Department of Horticulture, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj during 2021-22 and 2022-23. The experiment consisted of sixteen treatments viz T0- Control, T1- Ca(NO3)2 (2%), T2- K2SO4 (2%), T3- Ca(NO3)2 (2%) + K2SO4 (2%), T4- Ca(NO3)2 (2%) + Bagging (Red colour polythene), T5- Ca(NO3)2 (2%) + Bagging (Green colour polythene). T6- Ca(NO3)2 (2%) + Bagging (Yellow colour polythene), T7- Ca(NO3)2 (2%) + Bagging (Silver colour polythene), T8- K2SO4 (2%) + Bagging (Red colour polythene), T9- K2SO4 (2%) + Bagging (Green colour polythene), T10- K2SO4 (2%) + Bagging (Yellow colour polythene), T11- K2SO4 2% + Bagging (Silver colour polythene), T12- Ca(NO3)2 (2%) + K2SO4 (2%) + Bagging (Red colour polythene), T13- Ca(NO3)2 (2%) + K2SO4 (2%) + Bagging (Green colour polythene), T14- Ca(NO3)2 (2%) + K2SO4 (2%) + Bagging (Yellow colour polythene), T15- Ca(NO3)2 (2%) + K2SO4 (2%) + Bagging (Silver colour polythene) which were arranged in Randomized Block Design (RBD) with three replications. The foliar application of nutrients was done twice at ten days interval. The foliar application of nutrients was done twice at ten days interval days before Fifty-five days harvesting whereas Bagging of fruits was employed approximately at 30 days before harvesting of fruits using red, yellow, silver and green colours polythene bags. Analysis of the data indicated that treatment T14- Ca(NO3)2 (2%) + K2SO4 (2%) + Bagging (Yellow colour polythene) reported to be best for parameters namely Average fruit weight (163.88), Fruit width (cm) (8.37), Fruit length (cm) (6.17),Volume of fruits (cm3) (172.03) Yield/plant (kg) (5.49), Insect damage fruits (%) (0.68), Organoleptic quality (9.78).

8 of 11 groups shown: named compounds and organisms first, then groups whose results differ (checked claim by claim), then those with positive and negative results, then the smaller groups.

Claims are grouped by organism, treatment and what was measured or targeted. A paper counts as positive when any of its claims in the group is positive.
