University of Agriculture & Technology, Kumarganj, Faizabad, Uttar Pradesh, India Effect of integrated nutrient management on growth and yield of wheat ( Triticum aestivum L.) RN Maurya, Uday Pratap Singh, Sunil Kumar, AC Yadav and RA Yadav Abstract A field experiment was conducted during rabi season of 2013-14 at N. D. University of Agriculture & Technology, Kumarganj, Faizabad to study the effect of integrated nutrient management on the performance of Wheat (Triticum aestivum L.) variety HUW-234 which maturity period was 120-125 days. Treatments consist of 12 levels of fertility were evaluated in a randomized block design. Under the investigation, significantly highest number of tiller m -2 , leaf area index, length of spike (cm), grain spike - 1 , grain yield and straw yield (kg ha -1 )were found under incorporation of 125% recommended dose of fertilizer + 25% N through vermicompost (T12), however, highest harvest index (%) was recorded under application of 100% RDF + 25% through FYM (T7), while highest net return (Rs.ha -1 )and benefit: cost ratio was observed under 100% RDF + 25% through vermicompost (T9).

Wheat is cultivated globally on an area of 222 million hectares adding 717 million tonnes of grains annually to the world food basket, with an average productivity of 3229 kg ha -1 (FAO, 2015-16). It is the most important Rabi cereal crop of India, cultivated on an area of 29.25 million hectares and 88.89 million tonnes of total production with an average 3039 kg ka -1 . In Uttar Pradesh, wheat is the cultivated in an area of 9.63 million hectare with an annual production of 30.16 million tones with average productivity of 3113 kg ha -1 (Anonymous, 2016) [1] . In an intensively crop growing area of India, a high annual productivity of crops result in removal of nutrients in substantial amounts that after exceed replenishment through chemical fertilizer and manures ultimately leading to poor soil health. Yields decline and increasing production factors have been reported. Growers have started to use of higher doses of fertilizers, to maintain productivity. Such emerging trends of indiscriminate use of fertilizer without use of organic sources of nutrients are also responsible to deterioration of soil health. Imbalance fertilizer use has resulted in multinutrient deficiencyin soils. Therefore, soils encounter a diversity of constraints because of soil quality and ultimately end up with poor functional capacity (Singh and Jat, 2016) [7] . The low recovery of applied plant nutrient by crop raises the question of the fate of the applied fertilizer i.e. not use by crop. This plant nutrient may be lost from the soil-plant system through run-off, fixation, leaching, denitrification and volatilization. Hence the use efficiency of fertilizer needs to be enhanced to maintain the productivity of crops. It can be achieved only if application rates consistently exceed decomposition rates. Apart from this, theconstraints in the fertilizer production, there escalating costs, and low fertilizer use efficiency also call for more attention to the integrated nutrient management system (Singh et al., 2004 and Sharma et al., 2004) [5, 4] . Nutrient schedule along with balanced fertilization using organic manures as considered as promising agro-technique to maintain yield, increase fertilizer use efficiency and to restore soil fertility. The strength of the combined use system also lies in its ability to meet the short-term as well as long-term nutrient requirements of crops through the fast releasing fertilizer nutrient pool and the slow releasing organic nutrient pool respectively. The integrated nutrient supply including the use of chemical fertilizers, organic manures like FYM along with bio-fertilizers helps not only in bridging the existing gap between the nutrient removal and addition but also in ensuring balanced nutrient proportion as well as boost the productivity of wheat. Organic matter is the substrate for a large number of soil living beneficial organisms which are
