Abstract
- Glauconite is a potassium (K) bearing mineral, which generally contains 6–10% K<subscript>2</subscript>O and mostly available in various natural deposits in India. Glauconite mineral was converted to nano-particle form by grinding in a high-energy ball mill. The release of K from glauconite nano-particle in soil was studied in a pot culture experiment. Five different treatments viz., 0 mg K<subscript>2</subscript>O kg<superscript>−1</superscript>, 100 mg K<subscript>2</subscript>O kg<superscript>−1</superscript>, 150 mg K<subscript>2</subscript>O kg<superscript>−1</superscript>, 200 mg K<subscript>2</subscript>O kg<superscript>−1</superscript> used glauconite nano-particle (GNP) as a K source and 100 mg K<subscript>2</subscript>O kg<superscript>−1</superscript> from muriate of potash (MOP), were applied in soil to grow maize (Zea mays L.) plant. The highest K<superscript>+</superscript> concentration was observed in shoot at the application of 200 mg K<subscript>2</subscript>O kg<superscript>−1</superscript> through GNP and recorded 2 times more K<superscript>+</superscript> concentration in shoots as compared to 0 mg K<subscript>2</subscript>O kg<superscript>−1</superscript> treatment whereas 1.1 times more than the MOP treated soil at 5<superscript>th</superscript> harvesting stage. Selected plant physiological parameters namely electrical conductivity of plant cell, height, leaf area and nitrate reductase activity were also recorded maximum at 200 mg K<subscript>2</subscript>O kg<superscript>−1</superscript> GNP treated soil. Overall, glauconite nano-particle could supply K throughout the growth period and enhanced biomass yield of maize plant without showing any K deficiency symptom. [ABSTRACT FROM AUTHOR]
