Abstract:
A field experiment was conducted to study the effect of silicon (diatomaceous earth) on chlorophyll content, net return and BC ratio of wheat during rabi 2017-18 at Instructional Farm, Rajasthan College of Agriculture, Udaipur on clay loam soils having medium fertility status. Results showed that application of silicon significantly increased chlorophyll content at 60, 75, 90 DAS and at harvest of wheat under organic farming. Amongst stage of silicon application, tillering stage registered significant improvement in chlorophyll content. It was also reported that net return was maximum at 8g/liter Si application at tillering stage. It was concluded that application of 8 g silicon/litre of water at tillering stage resulted increased chlorophyll at all stages and economics wheat.
