Experiments were conducted in 1999 and 2000 to determine the effects of plant density (intra-row spacing) and planting dates on yield and quality characters of sugar beet. Root yield was affected by plant spacing, sowing dates, and plant spacing x sowing dates in 2000. The 15 and 20 cm intra-row spacing produced higher root yield than the 35 cm intra-row spacing. Mean yields of plant spacing for the 5 May sowing date were less than of the 5 February or March sowings. The plant spacing x sowing date interaction was large for sugar yield in 2000. Sugar yield was significantly higher for the February and March sowing dates compared to 5 May. Date of sowing did not significantly affect purity, but percentage of dry matter was reduced from 27.24% for the 20 February sowing date to 24.78% for the 5 May sown plots in 1999. Ash content and noxious nitrogen were affected by sowing dates only in, 1999.
