Impact of Integrated Nutrient Management (INM) on Growth Attributes of Strawberry (Fragaria × ananassa Duch.) cv. Winter Dawn

Abstract

A study entitled Impact of Integrated Nutrient Management (INM) on growth attributes of strawberry (Fragaria × ananassa Duch.) in district Banda, Uttar Pradesh was carried out at the "Green shade Net house" located in the Department of Fruit Science, College of Horticulture, Banda University of Agriculture & Technology, Banda (U.P.), during the academic years of 2022-23 and 2023-24. Eleven treatments using various combinations of N, P, K, nano urea, bio fertilizers, and organic manures were tested in a Randomised Block Design with three replicates. The experiment's primary objective was to determine the effect of nano technology on the vegetative growth traits of strawberry cv. Winter Dawn. According to the findings of 2 years study and pooled results, application of treatment T4 [75% N (Nano Urea) + 75% PK (Basal) + 250 kg VC + AZO + PSB] proved to be most effective treatment to increase growth attributes of strawberry i.e., plant height 9.09 cm, 13.61 cm and 17.78 cm at 30, 60 and 90  DAP, respectively; plant spread i.e.,  12.75  cm, 21.32 cm, and 23.44 cm at 30 ,60 and 90 DAP, respectively;number of leaves i.e., 5.75, 13.81 and 17.87 at30, 60 and 90 DAP, respectively; leaf length i.e., 4.70 cm, 5.80 cm and 8.29 cm at 30, 60 and 90 DAP, respectively; leaf width i.e., 5.94 cm, 7.53 cm and 11.60 cm at 30, 60 and 90 DAP, respectively; Leaf area (cm2) i.e., 40.31 cm2, 51.93 cm2,66.38 cm2 number of runners per plant i.e., 5.27, number of crowns per plant i.e., 4.39, biomass of fresh weight (g) i.e., 147.37 g and Biomass of dry weight (g) i.e., 36.84 g. Therefore, application of 75%N (Nano Urea) + 75% PK (Basal) + 250 Kg VC + AZO + PSB] proved to be most effective treatment to increase growth attributes of strawberry and same can be recommended to the growers.
