Influence of different moisture levels in soil, on the preservation of three potato varieties.

Chao R., Roque R., Alvarez P. Influence of different moisture levels in soil, on the preservation of three potato varieties.

Science of Soil, Irrigation and Mechanization, Volume 2, No. 1: 51-58, 1992, Cuba.

In the Potato Experimental Station in Havana it was carried out an experiment, with the purpose of knowing the behaviour of the potato for their preservation with respect to the vegetative resting, the loss of weight by sprouting, rot losses as well as the total loss of weight. It was evaluated 3 potato varieties: Desiree, Baraka and Spunta, which applied different amounts of water during its total crop, by the design of the centre line of sprinklers. The total water in these areas or levels of humidity was: Zone 1 – 4706 m3/hectare, Zone 2 – 4363 m3/hectare and Zone 3-3242 m3/hectare.

After the retention time finish, it was found that the moisture levels of Zones 1 and 2 were the best for the different indices studied, it was found no differences for these two levels of humidity. It is recommended that the humidity levels 1 and 2 in the varieties studied when the tubers are kept for seed or for consumption in the long term.
