Effect of foliar application of micronutrients on chemical composition, plw and keeping quality of guava(Psidium guajava L.) CV. sardar

Foliar application of micronutrients showed positive response on quality attributes of guava fruits maximum value of TSS (11.80 Btix), reducing sugar (4.52%) and total sugar (7.40%) was observed due to the foliar application of Zinc sulphate @ 1%. Minimum acidity (0.35%) was observed due to the treatment with 1 percent Ferrous sulphate, while minimum physiological weight loss (3.10, 7.60, 8.00 13.14 respectively) was recorded on 2^nd, 4^th, 6^th and 8^th days of storage, due to the treatment with Cuso₄@1%+Feso₄@1%+Znso₄@1% + Borax @ 0.50%. This treatment recorded good keeping quality of fruits (7.10 days). Maximum physiological loss in weight and minimum keeping quality was observed in control treatment.
