Abstract
An experiment was conducted during 2021–22 to study the “Impact of foliar application of NAA, zinc and boron on growth, yield and quality parameters of guava (Psidium guajava L.)”. For this thirteen-year-old uniform in growth 30 plants of guava planted at 6 x 6m apart were selected for this experimentation work in the garden, Department of Fruit Science, C.S. Azad University of Agriculture and Technology, Kanpur-208 002 (U.P.), India. There were in all ten treatments viz. three levels each of NAA (25, 50 and 75 ppm), ZnSO4 (0.5, 0.75 and 1.0%) and borax (0.4, 0.6 and 0.8%) along with one control, replicated thrice in RBD were used for the experimentation work. The recommended dose of fertilizers along with uniform horticultural were applied in cultural practices all treatments including control. The plant growth regulator and mineral nutrients were sprayed on the plants before flowering on 11/08/2021 and the second spraying in the third week of September after fruit setting on 17-09-2021 with a sprayer having a very fine nozzle from the exiperiment in seprated that the spraying of zinc sulphate @ 1% results in minimum fruit drop (40.87%) and maximum number of flowers per shoot (54.66), fruit set (56.89%), fruit retention (59.13%), fruit length (7.23cm) and width (6.77cm), weight (125.57g g), and volume (131.71cc), fruit yield (46.95kg/plant), total soluble solids (11.55°Brix), total sugars (6.41%) reducing sugar (3.10%) and non-reducing sugar (3.31%) with minimum percentage of titratable acidity (0.43%) under plains of central Uttar Pradesh.
