Abstract
This study was carried out to determine the most suitable irrigation schedules and sources of manure for maize under Mardin ecological conditions. Four sources of fertilizer and three irrigation schedules were applied in hybrid maize cultivar to find out their effects on the yield and yield components in 2014 and 2015 years. The study was conducted in the fields of Kiziltepe Vocational High School of Mardin by using randomized complete block with split block design with three replications. The plant height, first cob height, cob length, number of seeds per cob, cob yield, 1000 seed weight, seed yield per unit, hectoliter, protein and oil ratio in seed, Mg, K, Fe, Ni, Cu, Zn, Mn, Na, Ca content seed were significantly affected by irrigation schedules and sources of fertilizer levels during both years. While the highest values were obtained from chicken manure with 9646 kg ha-1 and 11019 kg ha-1 for first and second years, the lowest values were obtained from control with 6363 and 6662 kg ha-1 for years, respectively. But the difference between 180-80 kg N-P2O5- ha-1 and chicken manure was not statistically significant in the second year. According to the irrigation schedules the grain yield ranged between 6386-10678 hg/ha in the first year and 7575-12133 kg ha-1 in the second year. The lowest grain yield was obtained from the four irrigations application, whereas the highest values were obtained from the six irrigations application
