Abstract:
The present investigation entitled “Impact of foliar spray of nutrients and fruit bagging on growth yield and quality of guava (Psidium guajava L.) cv. Allahabad safeda was conducted at guava orchard of Horticulture Research Farm^-I, Babasaheb Bhimrao Ambedkar University Lucknow (U.P.), during rainy season of 2020-21 and 2021-22. Among the 51 guava trees with even size and vigour were selected and were sprayed with various concentrations of different nutrients (Borax @ 0.1% and 0.2%), (ZnSO₄ @ 0.2% and 0.4%) with and without borax (1.0%). The study was conducted in RBD (Randomised Block Design) with 17 treatments which replicated thrice. Fruits were analysed for their physical and chemical characteristics in the laboratory of Department of Horticulture. The results of present study revealed that the fruit’s physical characters i.e. fruit weight 128.96 g., total soluble solids 11.30 Brix. vitamin C 200.67 100 mg g^-1, and pectin percentage 1.256 5 were improved significantly with the use of Borax 0.2% + Zn 0.4% (T₉) and fruit were bagged/covered with Foam bag + Brown paper + Blue polythene. While maximum acidity percentage were recorded 0.453% under controlled (T₁)
