A field experiment entitled Influence of chemical fertilizers and micronutrients on nutrient uptake and quality parameter under maize-wheat cropping system was conducted at Pot house of the Department of Soil Science and Agricultural Chemistry, Chandra Shekhar Azad University of Agriculture and Technology, Kanpur for two consecutive year of 2016-17 in kharif season and 2017-18 in rabi seasons in micro plots. The experiment consisted of 9 treatments viz. Control, N(150), N(150) + P (75), N (150) + P(75) + K (75), N (150)+P (75)+K (75) +S (60), N (150)+P (75)+K (75)+Zn (5), N(150) + P(75) + K(75) + S(60)+ Zn (5), N (150)+P (75)+K (75)+S (60)+Zn (5)+Fe (10) and N (150)+P (75)+K(75) +S (60)+Zn (50)+Fe (10)+Az which were replicated four times in randomised block design (RBD). Maize (cv-Azad Kamal) and wheat (cv. PBW-343) were taken as trail basis on maize-wheat cropping system. The results revealed that the significant improvement in the physical properties (Bulk density, Hydraulic conductivity and Water stable aggregates) and chemical properties like cation exchange capacity and total organic carbon content of the soil were recorded by silty clay loam in texture, acidic in reaction (pH 7.8), medium in organic carbon (4.0 g kg-1) with 180, 10.11 and 170.0 kg ha-1 of available N, P and K, respectively. Nine treatment combinations were replicated four times in RBD. Surface (0-15 cm) and subsurface (15-30 cm) soil samples taken after the harvest of wheat (rabi, 2017-18) were analysed for pH, organic carbon, available N, P and K using standard analytical methods. Besides, different fractions of N, P, K, S, Zn and Fe were also determined in the soil samples taken after the wheat harvest (2017-18) and the composite soil samples drawn from adjacent fallow plots. The results revealed that the nutrient uptake in grain and stalk/stover of wheat and maize were analysed highest with the application of N(150)+P (75)+K(75) +S (60)+Zn (50)+Fe (10)+Az while lowest were found in control treatment. All the application with or without S, Zn and Fe along with NPK were also recorded higher nutrients uptake over control treatment during both of the year. Quality parameter (protein) in maize and wheat was recorded significantly highest with the application of N(150)+P (75)+K(75) +S (60)+Zn (50)+Fe (10)+Az. while lowest were found in control treatment. All the application with or without S, Zn and Fe along with NPK were also recorded higher nutrients uptake over control treatment during both of the year.
