The effect of water logging duration and nitrogen levels on performance of maize and nutrient uptake were studied in field at Pantnagar using a maize variety D-822 in split plot design with four replications in two cropping seasons. The main plot treatment consisted of four duration of water logging (0, 24, 48 and 72 hours) and subplot, three levels of nitrogen (60, 120 and 180 kg ha−1). The cob length, cob diameter, number of grain rows per cob, number of grains per row, 100 grain weight, and grain and stover yield were significantly decreased with increasing duration of water logging as compared to control (non-waterlogged) treatment, however, these were significantly increased with increase in nitrogen levels. The increase in nitrogen application from 60 to 180 kg ha−1, significantly increased nitrogen, phosphorus, potassium, iron and manganese uptake by maize. However, these were significantly decreased with increasing water logging duration from 0 to 72 hours.
