Abstract

The study was targeted to enhance the physical and visual appearance of rainy season guava which ultimately increasing guava growers’ income. 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 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 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 results revealed that the fruit physical characters i.e. fruit diameter (6.87cm), fruit length (6.39cm), fruit width (6.28cm), fruit weight (129.33g), fruit volume (128.96cc) were improved significantly with the use of Borax 0.2% + Zn 0.4% (T9) bagged with Foam bag + Brown paper + Blue polythene followed by fruits sprayed with (Borax 0.2 + Zinc 0.4% + Foam bag + News Paper + Blue Polyethylene bag) (T13) than the other treatments, while lowest was recorded under control.

Conclusion

Based on the information provided, it can be concluded that foliar spray of borax at a concentration of 0.2% and zinc at a concentration of 0.4% resulted in a significant response in guava plants. Additionally, when fruits were protected using foam bags, followed by yellow polyethylene bags and then brown paper bags, better physical parameters of the guava fruits were observed. Therefore, it is suggested that guava growers consider employing the foliar spray of borax and zinc at the specified concentrations and use foam bags, followed by yellow polyethylene bags and brown paper bags for fruit bagging. These practices may lead to improved fruit quality and overall yield for guava crops.
