Effect of Different Level of Nano Urea on Yield, Quality and Shelf life of Strawberry (Fragaria X ananassa) cv. Winter Dawn under Prayagraj Agro Climatic Condition, India

Abstract

Nano fertilizers are the modern day concept of fertilizers and possess several benefits over conventional fertilizers. In very small quantity nano fertilizers have significant impact on the growth of crop. The present study consisted of 11 treatments utilising various combinations of conventional urea and nano urea, administered at varied doses 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 yield and quality characteristics along with shelf life 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 [15.69 (2022-23), 16.23 (2023-24) and 15.96 (Pooled)] number of fruits per plant, [168.57 (2022-23), 177.28 (2023-24) and 172.92 (Pooled)] g yield per plant, [55.07 (2022-23), 57.92 (2023-24) and 56.49 (Pooled)] q/ha yield per hectare, ) [11.21 (2022-23), 11.54 (2023-24) and 11.38 (Pooled)] °Brix TSS, [0.60 (2022-23), 0.49 (2023-24) and 0.55 (Pooled)] % titrable acidity, [55.14 (2022-23), 56.86 (2023-24) and 56.00 (Pooled)] mg/100g ascorbic acid, [5.80 (2022-23), 6.00 (2023-24) and 5.90 (Pooled)] % total sugar, [4.17 (2022-23), 4.26 (2023-24) and 4.22 (Pooled)] % reducing sugar, [1.54 (2022-23), 1.65 (2023-24) and 1.60 (Pooled)] % non-reducing sugar and [4.34 (2022-23), 4.38 (2023-24) and 4.36 (Pooled)] days shelf life.
