Effect of Micronutrients on Physico-Chemical Parameters of Fruit and Yield of Guava (Psidium guajava L.) cv. L-49

This research was done to find out the effect of micronutrients on physico-chemical parameters of fruit and yield of guava (Psidium guajava L.). For this purpose, guava var. L-49 was used in this research. The experiment consisted of eight treatment combinations having Zn, Mn and Fe concentrations of 0.5, 0.5 and 0.4 % respectively, in Randomized Block Design with three replications. There was a significant effect of micronutrients (Zn, Mn and Fe). According to the results, significant increases of fruit size (cm), fruit weight (gm), volume of fruit (cm3), specific gravity and chemical parameters are Total soluble solids (TSS 0Brix), acidity (%), ascorbic acid (Vitamin ‘C’) (mg/100gm pulp), of fruit were determined with increasing micronutrients application. This experimental research carried out at Horticulture Research Farm, Department of Horticulture, Babasaheb Bhimrao Ambedkar University, Vidya-Vihar, Rae Bareli Road, Lucknow 226 025 (U.P.) during the summer season of 2019-20.
