Abstract: A field experiment was conducted to study the effect of silicon (diatomaceous earth) on growth, yield and nutrient uptake 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 grain and straw yield as well as yield-attributing parameters such as plant height, number of effective tillers/meter row length, number of spikelet’s/ear, number of grains/ear, ear length and grain weight/ear at harvest of wheat under organic farming. The greatest grain and straw yields were observed with the application of silicon 8 g/litre as compared to 2, 4 g/litre and control. The concentration and uptake of silicon, nitrogen, phosphorus and potassium in grain and straw were also greater under this treatment compared to others. Amongst stage of silicon application, tillering stage registered significant improvement in most of the yield attributes, consequently grain, straw and biological yields over CRI and jointing stages. It was concluded that application of 8 g silicon/litre of water at tillering stage resulted increased grain, straw yield, nutrient uptake and economics of NPK and silicon.
