Abstract: Guava is one of the important fruit crop cultivated all over India. A guava plant shows micronutrient deficiency which could be responsible for lesser yield and quality. Foliar feeding of nutrients to fruit plants has gained much importance in recent years which is quite economical and obviously an ideal way of evading the problems of micronutrients availability and supplementing the fertilizers to the soil. The present investigation was conducted at Horticultural College & Research Institute, Periyakulam during 2018-2019. The experiment was raised on well-established orchard of 3 years old Lucknow -49 guava trees which are planted at 3.0 x 1.5m spacing. The experiment was laid out in Factorial Randomized Block Design (FRBD) with five treatments replicated four times with two different grades. The results revealed that the application of RDF + Enriched MN Mixture (Soil)@2kg/tree + Foliar spray of [email protected]% (T3) recorded highest fruit yield of 47.90 t ha-1 , followed by T1 recorded next highest fruit yield of 37.60 t ha-1while the control (T4) recorded the lowest of 19.60 t ha-1 , The treatment T3 recorded the highest in quality parameters with reducing sugar(8.02%), non-reducing sugar(6.93%) and lowest acidity(0.42%) Hence application of grade I RDF + Enriched MN Mixture (Soil)@2kg/tree + Foliar spray of [email protected]% can be advocated in increasing the yield and quality of Guava
