Abstract:

An experiment was carried out in Kittur Rani Channamma College of Horticulture, Arabhavi, Belgaum District, Karnataka state to know the response of soil application of diatomaceous earth (DE) as a source of silicon on leaf nutrient status of guava. Leaf sample under different treatment were collected and utilized for analysis of nutrient status. The highest macronutrient viz., Nitrogen (2.13%), Phosphorous (0.32%) and Potassium (0.65 %) were recorded in plants applied with Half of RDF, Recommended dose of fertilizer (RDF), Half of RDF,RDF + 1kg/plant of DE, and RDF + 3kg/ plant of DE and RDF + 3kg/ plant of DE respectively. The Micronutrients of guava leaves viz., Calcium (1.39%), Magnesium (0.44%), Zinc (77.55 ppm), Iron(136.58), Silicon (0.45%), manganese (260.53), and Copper (67.45 ppm) were also recorded in plants applied with RDF + 3kg/plant DE.


Keywords: Diatomaceous Earth (DE), Silicon, Macro nutrient, Micronutrient.
