Impact of integrated nutrient management on growth, yield and nutrient uptake by wheat (Triticum aestivum L.)

Abstract

A field experiment was conducted during rabi season of 2005-06 at the Agricultural Research Farm, T.D. College Jaunpur, in randomized block design with three replications to assess the effect various types of organic and inorganic fertilizers on growth, yield attributes and NPK acquisition. The results revealed that growth attributes viz. number of tillers hill-1 and plant height significantly increased due to presence of nitrification inhibitors in nimco fertilizer, they slowly supplied nitrogen to plant and decreased the looses of nutrients resulting more nitrogen available to plant. Combined application of organic manures and inorganic fertilizers increased the dry matter accumulation, number of grains spike-1, grain yield, straw yield and NPK uptake by wheat crop compare to treatment T2 where full dose of NPK applied through urea, single superphosphate and murate of potash. Application of 50% N through nimco and 50% through Bhu amrit showed maximum number of tillers hill-1, plant height, number of grains spike-1, dry matter accumulation and test weight. The highest grain and straw yield of wheat to the extent of 44.9 and 69.56 q ha-1, respectively was obtained where recommended dose of nitrogen was applied in ratio of 1/2:1/2: through nimco and Bhu amrit, respectively. © 2011 Knowledgia Review, Malaysia.
