Introduction to Banana Water Needs: A Full Analysis of Banana Growth Water Requirements
Bananas are a crop with a very high water content. At harvest, 90% of a plant with a fresh weight of 200 kg is water. For every 1 gram of dry matter assimilated, more than 600 grams of water are consumed, showing that bananas have very high water requirements. When water is lacking, the leaves lose their green color and become thinner, the fingers become shorter, the pseudostem is shorter, growth is delayed, and harvest is postponed by more than 20 days, resulting in reduced yield...
Bananas are a crop with a very high water content. At harvest, 90% of a plant with a fresh weight of 200 kg is water. For every 1 gram of dry matter assimilated, more than 600 grams of water are consumed, showing that bananas have very high water requirements. When water is lacking, the leaves lose their green color and become thinner, the fingers become shorter, the pseudostem is shorter, growth is delayed, and harvest is postponed by more than 20 days, resulting in reduced yield. If the groundwater level in a banana plantation is too high and the plants become waterlogged, the banana roots can also die from lack of oxygen.
In China's banana-producing areas, the annual rainfall before harvest is above 1500 mm, but the rainfall is extremely uneven. In summer there is often excessive rain, while in autumn and winter, when the fruit is developing, there is often drought, which is extremely unfavorable for banana growth. Even in the high-temperature summer season, in banana plantations with a low groundwater level or on hillside land, if there is no rain for a week, irrigation is needed; otherwise growth is affected. Therefore, to obtain high yields, good irrigation conditions are needed as a guarantee.
