The present investigation entitled “Integrated nutrient management approach on wheat (Trilicum aestivum L.) in vertisols” was carried out with the objective to evaluate the effective nutrient management for maximizing productivity of wheat. A field experiment was conducted during winter season of 2006-07 at College of Agriculture, Indore. The soil of the experimental field was sandy clay loam, slightly alkaline in reaction analyzing low in organic carbon available P, S and Zn as well as medium in available N and K contents. A set of ten treatments of nutrient management were tested in a randomized block design with four replications. The wheat variety Hl-8498 (Malwa Shakti) was sown on November 21, 2008 by drilling the seeds in rows at 28.5 cm apart. The crop was given N, P, K, S, Zn, B and Mn nutrient as per treatments through urea, single super phosphate, murate of potash, zinc sulphate, Borax and ammonium, manganese, respectively. In addition to these nutrients, farmyard manure and Azotobacter in respective treatments were also given with recommended dose of NPK. Five irrigations were given at different critical stages of the crop. Weed control was adopted for all the treatments and there were need of any plant production measures. The observations on growth parameters (plant height, number tillers/m row length, leaf area index, yield attributes (viz. effective tillers/m row length, characteristic of earhead, 1000-grain weight) and grain as well as straw yields were recorded. Nutrient (NPK) content and their uptake in grain and straw were also analyzed under all the treatments. The economic analysis (cost of cultivation, gross and net monetary returns and profitability of the treatments) on per hectare basis was circulated. After harvest of the crop soil samples from each plot were taken and analyzed to know the changes in chemical properties of the post-harvest soil. Finally, the data were statistically analyzed.
