Abstract
SummaryThe effects of four soil bulk densities (1.25, 1.40, 1.55, 1.70 Mg m−3) and two water regimes (high and low) were studied in the glasshouse at three different carrot growth stages (68,103,153 days after planting). The fresh weights of storage roots and tops, the ratio of these weights, the length of storage and lateral roots, and carrot shape were measured and statistically analysed. Soil bulk density had a significant effect on carrot yield and shape. All characteristics measured were significantly decreased at 1.70 Mg m−3. At this bulk density, 0.91 to 1.56 cm of storage root length was above the soil surface. In both watering regimes, the effect of bulk density was generally consistent at each growth stage. The yield was always higher in the high than in the low water treatment. The highest yield of 92.3 g plant−1 was recorded at 1.40 Mg m−3 in the high water regime. Carrot shape was more conical at high bulk density under low moisture conditions.
