Effect of foliar application of micronutrients on yield and economics of guava (Psidium GuajavaL.) CV. L-49

Abstract

A field study was carried out at the Fruit Research Station, Himayatbagh, Aurangabad, Vasantrao Naik Marathwada Krishi Vidyapeeth, Parbhani, during 2014–2015. The experiment was laid out in Randomized Block Design (RBD) with 12 treatments and three replications. Observations were recorded on growth, physical and quality characters of guava. The maximum number of fruits per plant and B: C ratio were recorded under treatment T10 (boric acid @ 0.3% + ferrous sulphate @ 0.4% + magnesium sulphate @ 0.7% + manganese sulphate @ 0.5% + zinc sulphate @ 0.5%) while highest yield/tree kg and yield/ha (Mt), highest GMR, NMR and EIOC (./ha), were recorded under treatment T11 (boric acid @ 0.3% + ferrous sulphate @ 0.4% + magnesium sulphate @ 0.7% + manganese sulphate @ 0.5% + zinc sulphate @ 0.5% + copper sulphate @ 0.4%).
