Abstract
Three sources of nitrogen, sulphate of ammonia, calcium nitrate and urea applied at 0, 56 and 112 kg N per ha and at different times (sowing, singling and split?half applied at sowing and half at singling) were compared for sugar beet in 32 experiments conducted in the beet growing areas of Ireland in 1963, 1964 and 1965. In general, the different sources of nitrogen gave similar yields of sugar. Fifty-six kg N per ha gave significant yield responses each year and 112 kg were superior to 56 kg in 2 years. Nitrogen applied at sowing time or as a split dressing gave similar yields and both were significantly better than N applied at singling.
