Effect of foliar spray of macro and micro nutrients on growth and establishment of grape (Vitis vinifera L.) cv. Thompson Seedless under Prayagraj agro climatic condition

Abstract

Grapes (Vitis vinifera. L) is one of the important commercial subtropical crops which is a good source of vitamins and minerals. It is grown throughout the world except the places with extreme temperature and high altitude. So, to find out Effect of foliar spray of macro and micro nutrients on growth and establishment of grapes cv. Thompson Seedless under Prayagraj agro climatic condition; a field experiment was conducted at Horticulture Research Farm, Department of Horticulture, Sam Higginbottom university of Agriculture, technology and science, Prayagraj, U.P-211007 during the year 2023-2024. The experiment comprised of 8 different treatment of three different micro nutrients comprising of Fe @ 0.2%, Zn @ 0.4% and Mg @ 0.02% respectively. The main objective of the experiment was to evaluate the root and vegetative growth of grapes plant with their success and survival in the Prayagraj agro-climatic zone. From the present investigation concluded, the application of T5 (NPK + Fe @ 0.2% + Zn @ 0.4% + Mg @ 0.02%) was found growth of grape plant in terms of plant height, survival percentage, root length, number of leaves and leaf area etc. It also showed the best root growth parameters with maximum root length 9.71cm @ 120 DAP and maximum root thickness 4.17 mm @120DAP. It also showed best vegetative growth parameters with maximum new shoot length 9.48 cm @ 120DAP, maximum Number of new sprouts 10.56 @ 120 DAP, highest number of leaves with 14.22 @ 120 DAP, maximum leaf area 66.17 cm2, maximum plant height after transplanting 15.67 cm and highest survival percentage 73.44% of grapes plant.
