Abstarct: In order to study Integrated crop Management (ICM) system the effect of wave-halo hardening priming at different levels of nitrogen on yield and yield components of early corn (Zea mays L.), a field experimental was conducted during growing season of 2013 at farm of faculty of Agricultural Shahrood university . The experiment was a factorial experiment in the baxse of randomized complete blocks design with three replication. Factors included halo hardening at two levels (prime in -6 bar and non-prim), wave priming at two levels (prime for 2 minutes at 42 kHz and not prime) and nitrogen at three levels of dividing(post emergence, 1 week before flowering and filling period). The results suggested significant effect of priming on plant height, ear diameter, the number of kernel per row, kernel rows per ear, chlorophyll, seed yield, 1000 seed weight, biological yield and harvest index. Also results showed that nitrogen dividing in all levels of treatment was a significant. Interaction of halo hardening and wave priming and nitrogen dividing was significant on plant height, ear diameter, kernel rows per ear, chlorophyll , biological yield, 1000 seed weight and RWC. The test showed good growth in corn and weed could overcome.
