Abstract
Effects of different levels of N and intra-row plant spacing on yield and yield components of maize cv. "Golden" was studied at the University of Agriculture, Faisalabad during 1998. The nitrogen levels comprised 0-100-140 and 180 kg ha" while the intra-row plant spacing were 10, 20 and 30 cm. Both nitrogen and plant spacing had a significant effect on plant height, number of grains per cob, 1000-grain weight and harvest index. The maximum grain yield (5.7 t ha") was produced when plant spacing was kept 'as 20 cm and N was applied at the rate of 180 kg ha". Key words: Nitrogen, intra-row plant spacing, yield components, maize
