This field experiment was conducted during the kharif season of 2014 and 2015 at the Indira Gandhi Krishi Vishwavidyalaya, Raipur (C.G) to find out the effect of crop arrangement and nutrient management on availability of nutrients under maize and soybean intercropping system. Treatments comprised of six cropping arrangements viz. sole maize (C1), sole soybean (C2), two replacement series of maize + soybean (2:2, C3 and 2:4, C4), two additive series in which two rows (C5) and one row (C6) of soybean were added in-between two rows of maize and four fertility levels viz. 125% recommended dose of fertilizer (RDF) (F1), 100% RDF (F2), 75% RDF (F3) and 50% RDF (F4). Uptake of N and P was higher in grain than stover but in case of K uptake reverse trend was recorded. Maize under intercropping system performed better than sole maize. Replacement series 2:4 maize: soybean recorded highest uptake of NPK over remaining treatments. Uptake of nutrients followed an increasing trend with increase in NPK dose under nutrient management. 125% RDF performed better than other fertility levels.
