Determination of the efficiency of nbpt-coated urea in wheat and corn

This study is placed in two different locations as Aliaga County and Tire County of the city of Izmir with the aim of the trial of efficiency of NBPT-coated urea nitrogen in wheat and corn. In the trial run in Aliaga County, Ziyabey used 98 kinds of bread wheat while in the one run in the village of Derebasi of Tire county, Limagrain used 30,709 kinds of silage corn. The trials are located as 4 repeats according to trial patterns of randomized blocks in the season of 2014-2015. In the study, anther height, anther grain size, nitrogen content and the impacts on total yield by applying NBPT-coated urea nitrogen in the plant of bread wheat in exact and half doses are researched while in the plant of silage corn, stem length, stem thickness, grain size in a stem, nitrogen content and the impacts on total yield in exact doses are analyzed. According to the research results, it has been determined that NBPT-coated urea nitrogen enables dramatic increases in the yield and the elements related to productiveness in bread wheat and silage corn.
