ABSTRACT
Spring maize has become popular owing to higher yields. Besides, their sowing periods are flexible and thus can be fitted in any cropping system. The spring crop is sown during late January to end of February. The productivity of maize is largely dependent on its nutrient management particularly that of nitrogen as maize is a heavy feeder of nitrogen. Crops like soybean, black gram, green gram and cowpea are raised mixed with maize. These legume crops are grown in space between 2 rows of maize. In Bihar, mixed cropping of groundnut with maize is quite profitable. In certain areas, maize is intercropped with pigeon pea. Maize is harvested when husk is turned yellow and grains are hard enough with about 30 % moisture. There is no need to wait for stalks and leaves to dry, because they remain green in most of the hybrids and composites.
