The effect of water table depth on yield of sugarcane varieties PR 980, PR 1028, PR 1059, PR 1141, PR 64-610, PR 61-632 and PR 64-2705 was studied in lysimeter tanks in the field. Using plastic drains at varying distances and depths, variety PR 980 was studied on a 5-ha farm. Results obtained show that varieties differ in their response to water table conditions. Varieties PR 980, PR 1059, PR 64-610, PR 61-632 and PR 64-2705 yielded significantly more cane and sugar when the water table was lowered. Varieties PR 1028 and PR 1141 did not show statistically significant differences among treatment differentials. Under actual field conditions, using perforated plastic drains, variety PR 980 yielded significantly more sugar than in undrained plots. The results obtained in the lysimeter tanks are in accord with those observed under commercial production.

The effects of two water table depths (WTD), 0.6 and 0.9 m below the soil surface on subsidence, subsidence rate and swelling of an organic soil were observed in large undisturbed cores under greenhouse conditions. Measurements were made in two tiers, 0–0.3 m (top tier) and 0.3 m to WTD (bottom tier) during the growth of a carrot crop with WTD as above, and continued following a rise in the water table. The WTD of 0.9 m caused the top tier to subside twice as much as the same tier in the 0.6 m WTD. Top tier subsidence seemed irreversible in both WTD because minor swelling was observed following a rise in the water table. Most of the reversible subsidence occurred in the bottom tier. Raising the water table reduced the total profile subsidence by 36 and 24% for the 0.6 and 0.9 m WTD, respectively. After correction for oxidation, subsidence accounted for 3.2 and 5.9% of the 0.6- and 0.9-m profiles, respectively. The bulk density increase in the 0.6-m profile before and after the end of the experiment was not significant but a significant increase of 11% was measured in the 0.9-m profile. Subsidence rates decreased in both tiers during the growing period reaching a minimum in both WTD at harvest time. The subsidence rate in 0.9-m profile at 100 days after seeding was 2.5 times the rate in the 0.6-m profile. Key words: Organic soil, subsidence, swelling, water table

A study was conducted to determine the effect of water table depth on water use and tuber yields for subirrigated caladium (Caladium × hortulanum) production. A field-situated drainage lysimeter system was used to control water table depths at 30, 45 and 60 cm (11.8, 17.7, and 23.6 inches). Water use was estimated by accounting for water added or removed (after rain events) to maintain the desired water table depth treatments. In 1998, tuber weights, the number of Jumbo grade tubers, and the production index (tuber value index) of `White Christmas' were greater when plants were grown with the water table maintained at 30 or 45 cm compared to 60 cm. In 1999, tuber weights, the number of Mammoth grade tubers, and the production index, also were greater when plants were grown at water table depths of 30 or 45 cm compared to 60 cm. The average estimated daily water use was 6.6, 5.1, and 3.3 mm (0.26, 0.20, and 0.13 inch) for plants grown at water table depths of 30, 45, and 60 cm, respectively, indicating an inverse relationship with water table depth. While current water management practices in the caladium industry attempt to maintain a 60-cm water table, results from this study indicate that, for subirrigated caladium tuber production, the water table should be maintained in at 30 to 45 cm for maximum production on an organic soil.

In the northern hemisphere, variability in hydrological conditions was suggested to increase as a consequence of climate warming, which may result in longer droughts than the area has experienced before. Due to their predominately anoxic conditions, peatlands are expected to respond to changes in hydrological conditions, such as successive drying and rewetting periods. As peatlands are rich in organic matter, any major changes in water table may influence the decomposition of it. The hydrological conditions may also influence release of nutrients from peat profiles as well as affect their transport to downstream ecosystems. In our mesocosm experiment, artificial water table fluctuations in pristine peat profiles caused an increase in dissolved organic nitrogen (DON) and ammonium(NH4+-N)concentrations, while no response was found in drained peat profiles, although originating from the same peatland complex.

Two Peaks

Carrots and onions were grown on organic soil in a greenhouse over four water table levels, 10, 20, 40, 70 cm from the soil surface. Carrot yields were reduced over the shallowest water table level only, whereas the onion yields were depressed by the 10-, 20-, and 40-cm water table levels. The longest carrots were produced in the 40- and 70-cm water table levels. Evapotranspiration for the carrots was the same in all treatments but the water use efficiency was greatest in the 40- and 70-cm water table levels. Evapotranspiration for the onions and water use efficiency were the greatest in the 70-cm water table level. The evapotranspiration curves for the carrots showed two peaks, the second one corresponding to a rapid growth from the 50th day after seeding. The evapotranspiration curves for the onions showed one peak following the 70th day after seeding. Onions appear to be much more sensitive than carrots to high soil water content.Key words: Carrot, onion, water table, organic soil, vegetables
