EFFECT OF INTEGRATED NUTRIENT MANAGEMENT ON YIELD, QUALITY AND ECONOMICS OF GUAVA

The experiment was conducted during 2009-10 at the Fruit Research Station, Kuthulia Farm, College of Agriculture, Rewa (M.P.) to evaluate the effect of integrated nutrient management on yield, quality and economics of guava. Application of 50 % RDF (250:100;250 g NPK)+25 kg FYM+ 5 kg vermicompost/tree (T8 ) and 100% RDF (500:200:500 g NPK) +Zn, B, Mn foliar spray +organic mulching 10 cm thick /tree (T4) were found significantly superior than other INM treatments with respect to yield attributes, yield and economics from guava cv. Allahabad Safeda. Under these treatments, fruit yield ranged from 89.07 to 90.0 qha-1 and economics from Rs.53204 to Rs.53439 ha -1 . Only total soluble solids were found in the higher range (12.23 to 12.430Brix) in T1 and T3 treatments. Other fruit qualities as well as fruit size were not influenced significantly due to INM treatments.
