Responses of two lowland: rice cultivars to the different sources and levels of nitrogen

Responses of two lowland: rice cultivars to the different sources and levels of nitrogen

Agrochimica 50(3/4): 158-164

In this investigation conducted during 2001 and 2002 in Shiraz, Iran, the yield and yield components of two lowland rice cultivars (G3, indica; and Dorudzan, japonica) were affected by different rates (0, 50, 100 and 200 kg ha-1) and sources of N (sulphur-coated urea, SCU; ammonium chloride, AC; and urea, U). Each successive rate of N increased the grain yield significantly up to 100 kg N ha-1, regardless of N sources and cultivars.
