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

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%).

Highlights

• The highest GMR, NMR and EIOC (./ha), were recorded in guava under treatment with boric acid @ 0.3% + ferrous sulphate @ 0.4% + magnesium sulphate @ 0.7% + manganese sulphate @ 0.5% + zinc sulphate @ 0.5% + copper sulphate @ 0.4%.
