Quantitative and qualitative enhancement in guava (Psidium guajava L.) cv. CHITTIDAR through foliar feeding


Journal Title:International Journal of Agricultural Sciences

The present experiment was conducted at the Department of Fruit Science, K.N.K. College of Horticulture, Mandsaur (M.P.) on six years old guava tree cv. Chittidar during 2011-2012. On the basis of results obtained in present investigation it is concluded that foliar spray of ZnSO4 0.8% + borax 0.4% + NAA 50 ppm + GA3 100 ppm was found best to increase fruit set, fruit retention, volume of fruit, pulp thickness, pulp weight, pulp per cent, length and diameter of fruit at harvest, average fruit weight, and reduced the seed per cent and seed pulp ratio which ultimately increased the yield per tree. Various quality parameters total sugars, reducing sugars, non reducing sugars, TSS, zinc and iron content in fruit pulp were also improved with application of ZnSO4 0.8% + borax 0.4% + NAA 50 ppm + GA3 100 ppm. Same treatment also recorded reduced fruit drop, minimum number of seeds per fruit, maximum TSS/acid ratio and minimum acidity per cent of fruit
