| Abstract | ||
| Field experiments were conducted for two seasons, Spring and Autumn of year 2011 at Basrah town in order to study the effect of foliar application of Fe (0,50 and 100 ppm) and four levels of Nitrogen (60,100,140 and 180) tan ha-1) which namely: N1,N2,N3 and N4 respective on growth and development of corn crop using RCBD with three replicates, treatments were arranged with factorial layout. The results showed that there were a significant variations for all traits under study which are plant height, LAI, 50% male and female flowering, Number of seed ear and weight of 100 seeds and this led to give higher grain yield of 5.543 and 4.938 tan ha-1 for spring and Autumn seasons respectively. Also the study showed that Autumn season gave higher grain yield than Spring season of year 2011. | ||
