Influence of Foliar Application of Secondary and Micronutrient Combinations on Plant Height and Plant Canopy Spread Attributes Pertaining to Guava cv. Allahabad Safeda

Abstract

In recent years, a large number of guava orchards have become chronically affected by bronzing because of imbalanced nutrient management. Hence, the experiment on effect of foliar application of secondary and micronutrients on major growth parameters viz., plant height (cm) and plant canopy spread (m2) of Guava cv. Allahabad Safeda is carried out at Regional Horticultural Research and Extension Centre, Bengaluru during August 2014 to March 2015 with fourteen treatment combinations which are replicated thrice. The results showed that the application of RDF + foliar spray of Zn + Mg + Mn @ 0.75 % + Cu +Fe @ 0.5% + MAP 0.5% recorded the maximum plant height (238.20 cm) and plant canopy spread (5.01 m2) where as minimum plant height (199.03 cm) and plant canopy spread (3.05 m2) was recorded in RDF+ foliar spray of Zn + DAP @ 0.5%.
