A long-term fertilizer experiment initiated in 1997 at Instructional Farm of the Rajasthan College of Agriculture, Udaipur, was selected for this investigation during 2000–01 and 2001–02, to evaluate the effect of integrated nutrient supply on productivity and nutrient uptake of maize (Zea mays L.)–wheat (Triticum aestivum L. emend. Fiori & Paol.) cropping system. Maximum plant height and leaf-area index (LAI) of maize were observed by applying 150% NPK, while dry matter was found maximum with 100% NPK + FYM 10 tonnes/ha. The results of both these treatments were at par in all growth parameters. Highest maize grain and stover yields were obtained by applying 150% NPK, though the results were at par with those obtained with 100% NPK + FYM 10 tonnes/ha. Application of 100% NPK + FYM 10 tonnes/ha showed highest values of growth parameters and grain yield of wheat, while maximum straw yield was recorded with 150% NPK. However, these 2 treatments were found at par. The balanced and integrated nutrient supply to maize and wheat showed significantly higher uptake of primary nutrients.


Key words
