Abstract

  Silica performs like a super growth supplement advised for use throughout the lifecycle of plant. Silica creates strong cell wall which leads to stronger and bigger branches and stem. This uptakes and transport more water, nutrients and plant secretions throughout the plant body, facilitating faster growth rate and stronger plant. This also helps the plant bear the load of the fruits at later stage. Silica enables enhanced metabolic function, showing higher concentration of chlorophyll in leafy tissues. It also enables better use of CO2 and higher rate of photosynthesis. Silica accelerates synthesis of protein and starch, increasing brix level in plants. Silica activates at least 60 different enzymes involved in plant growth. In the present investigation, Silica nano-composites were prepared by the use of silica solubilizing bacteria in silica derived potassium silicate. The results were found to be very significant as silica nano-composites increases the plant height of brinjal, number of leaves, number of new shoots and number of flowers in comparison to control. The silica nano- composites also showed reduction of the wide spread of insects and pests in brinjal crop. After 7 days of spray there was remarkable glow in the plant and vibrant vegetative growth. This leads to higher yield, better quality, weight, color, taste and longer shelf life.

Keywords: Silica; Agricultural Productivity; Plant Height; Leaves; Shoots; Flowers; Growth of Brinjal Crop
