Abstract

In this research, using a split-block design and implementing two single-line source sprinkler systems, effects of 0, 90, 180 and 270 kg N/ha as urea source and 9600, 8550, 7500 and 6400 m3/ha of Irrigation water on silage Corn (Zea Mays L. ), S. C. 704 variety in two conventional and minimum-Tillage systems were studied. The results showed that there was not a significant difference between water use efficiency, phosphorous uptake and foliages yield of two Tillage systems. The main effects of water and Nitrogen on the stems height and diameter, fresh foliage yield, Nitrogen, phosphorus and zinc uptake and the amounts of soil organic carbon were significant at 1% level and on the dry foliage yield and water use efficiency were significant at 0. 05% level. At all levels of Nitrogen, agronomic and physiological efficiencies in conventional Tillage were higher than those in minimum-Tillage system. The optimum amount of foliage yield in conventional Tillage system was obtained from combined application of 8550 m3/ha water and 90 kg N/ha and in minimum Tillage was obtained from combined application of 7500 m3/ha Irrigation water and 270 kg N/ha. In terms of water use efficiency, in conventional Tillage, combined application of 180 kg N/ha and 7500 m3/ha of water and in minimum Tillage combined application of 180 kg N/ha and 6400 m3/ha of Irrigation water were superior treatments. Based on obtained results, minimum-Tillage system can be used instead of the conventional system in the similar Corn fields but more Nitrogen and less water is required.
