Abstract:
Guava orchard experiment was conducted at Narseedwala village, tehsil Dhampur, district Bijnor (U.P.) during 2020-21. The trail consisting of sixteen treatment viz; T₁ (Borax @ 0.1%), T₂ (Zinc sulphate @ 0.3%), T₃ (Magnesium sulphate @ 0.2%), T₄ (Ferrous sulphate @ 0.2%), T₅ (Borax @ 0.1% + Zinc sulphate @ 0.3%), T₆ (Borax @ 0.1% + Magnesium sulphate @ 0.2%), T₇ (Borax @ 0.1% + Ferrous sulphate @ 0.2%), T₈ (Zinc sulphate @ 0.3% + Magnesium sulphate @ 0.2%), T₉ (Zinc sulphate @ 0.3% + Ferrous sulphate @ 0.2%), T₁₀ (Magnesium sulphate @ 0.2% + Ferrous sulphate @ 0.2%), T₁₁ (Borax @ 0.1% + Zinc sulphate @ 0.3% + Magnesium sulphate @ 0.2% + Ferrous sulphate @ 0.2%), T₁₂ (Borax @ 0.1% + Zinc sulphate @ 0.3% + Ferrous sulphate @ 0.2%), T₁₃ (Borax @ 0.1% + Magnesium sulphate @ 0.2% + Ferrous sulphate @ 0.2%), T₁₄ (Zinc sulphate @ 0.3% + Magnesium sulphate @ 0.2% + Ferrous sulphate @ 0.2%), T₁₅ (Borax @ 0.1% + Zinc sulphate @ 0.3% + Magnesium sulphate @ 0.2%) and T₁₆ control (water spray) sprayed at time of fruit set. Among different treatments, significantly maximum increase in annual shoot growth, plant height, stem girth, plant spread, number of fruit/plant, yield kg/plant and fruit quality of guava in terms were recorded in T₁₁ (Borax @ 0.1% + Zinc sulphate @ 0.3% + Magnesium sulphate @ 0.2% + Ferrous sulphate @ 0.2%).
