Effect of Different Level of Nano Urea on Growth of Strawberry (Fragaria X ananassa) cv. Winter Dawn, under Prayagraj Agro Climatic Conditions

Abstract

A research study was carried out at the Horticulture Research Farm, Department of Horticulture, NAI, SHUATS, located in Prayagraj, Uttar Pradesh, during the academic years 2022-23 and 2023-2024. The experiment comprised 11 treatments involving various combinations of conventional urea and nano urea, applied at different levels and concentrations, with each treatment replicated three times in a Randomised Block Design. The main objective of the experiment was to assess the impact of varying concentrations of nano urea on the growth characteristics of Strawberry (Fragaria X ananassa) cv. Winter Dawn. Treatment T7 [100% PK + 60% RDN + 0.8% Nano urea (8 ml/l)] was found best with [9.78 (2022-23), 10.05 (2023-24) and 9.91 (Pooled)] days to new growth, [31.11 (2022-23), 32.32 (2023-24) and 31.71 (Pooled)] days to runner formation after planting, [17.11 (2022-23), 17.79 (2023-24) and 17.45 (Pooled)] cm plant height, [17.62 (2022-23), 17.86 (2023-24) and 17.74 (Pooled)] number of leaves per plant, [66.21 (2022-23), 68.45 (2023-24) and 67.33 (Pooled)] cm2 leaf area, [5.27 (2022-23), 5.59 (2023-24) and 5.43 (Pooled)] number of runners per plant, [22.02 (2022-23), 22.33 (2023-24) and 22.19 (Pooled)] number of flower per plant, [71.13 (2022-23), 72.64 (2023-24) and 71.89 (Pooled)] % percentage of fruit setting (%) and [67.06 (2022-23), 69.07 (2023-24) and 68.07 (Pooled)] days taken to harvesting maturity.
