Response of foliar feeding of nutrients on quality attribute of guava (Psidium guajava)

The experiment was conducted at Department of Fruit Science. K.N.K. College of Horticulture, Mandsaur,during 2017-18,factorial randomized block design replicated three times. The treatment consisted of two factor (A) variety V₁- Chittidar, V₂-Allahabad Safeda and factor (B) nine levels of nutrients- N_o- control, N₁-zinc sulphate @ 0.3%, N₂- zinc sulphate @ 0.4%,N₃- calcium nitrate @ 1%,N₄- calcium nitrate @ 2%,N₅ -potassium sulphate @ 1%,N₆- potassium sulphate @ 2%,N₇- boron @ 0.2%,N₈- boron @ 0.4%. Among, varieties, maximum TSS (11.59°Brix) and non-reducing sugar (4.39%) were found in Chittidar (V₁) and maximum, TSS/Acid ratio (36.79) , reducing sugar (5.62%) and ascorbic acid (156.84 mg/100 pulp)was recorded in Allahabad Safeda (V₂) and the minimum acidity (0.32%) in Allahabad Safeda (V₂). The maximum, TSS (12.60°Brix), non-reducing sugar (4.56%) and TSS/ acid ratio (43.77)were observed in N₆potassium sulphate @ 2%, maximum reducing sugar (5.74%), ascorbic acid,(170.28mg/100 pulp) and total sugar (9.68%) in N₈ (boron@0.4%) and minimum, acidity (0.28%) was recorded in N₂ (zinc sulphate @0.4%).
