Abstract
With respect to the important effects of nitrogen (N) on plant growth and fruit production, a five-year experiment was performed to evaluate the effects of different sources of N fertilization including chemical and organic on the quantity and quality of citrus fruit. Using five-year old trees, different types of fertilization including ammonium sulfate, urea coated with sulfur, ammonium nitrate and manure were tested using seven treatments in five replicates from 2002 to 2007. Different plant quantitative and qualitative parameters were determined. The most effective strategy on fruit yield production was the use of urea coated with sulfur and manure with 92.46 kg ha−1 fruit yield followed by ammonium sulfate and manure (87.06 kg ha−1) and ammonium sulfate (86.43 kg ha−1). The combination of mineral and organic fertilization may be the most suitable fertilization strategy for citrus production.
