Abstract A method and apparatus for increasing the production of tuber-producing plants per unit area is disclosed. In accordance with this invention, a seed-tuber is planted in soil that is contained in a first box or frame unit. As the plant grows it develops new leaves and axil-buds. When the plant reaches a given height, which is different for different plants, a new layer of soil is added to the first box or frame unit. The new layer of soil does not completely cover the plant. Instead, a layer of soil is added such that the apical meristem is located at the soil surface or about one cm. below the soil surface. As the plant continues to grow another new layer of soil is again added in the manner described. When the level of the soil approaches the top of the first box or frame unit, a second box or frame unit designed to fit on top of the first box or frame unit is placed on top of the first box or frame unit. This second box or frame unit is open at the top and bottom, whereas the first box or frame unit may have a bottom plate. New layers of soil are then added in the second box or frame unit in the manner and at the times described above with reference to the first box or frame unit. This process is repeated with additional boxes or frame units being piled one on top of the other and new layers of soil added. After the last layer of soil has been added the plant is allowed to grow until it is ready for harvesting. Various different embodiments of the box or frame units of this invention are disclosed.
A method for increasing the yield in the cultivation of tuber-producing plants comprising the steps of: (a) planting a seed-tuber in a first box-like frame unit; (b) adding a new layer of soil in said first frame unit to cover the embryonal axil buds formed as the plant grows from the seed-tuber; (c) placing a second box-like frame unit on top of said first box-like frame unit when the soil added to said first box-like frame unit reaches the top of said first box-like frame unit; (d) adding layers of soil in said second box-like frame unit to cover the embryonal axil buds formed as the plant grows; and (e) adding additional box-like frame units one on top of the other as the plant grows, each time covering the embryonal axil buds with new layers of soil in said frame units as said plant grows until the pile of soil formed reaches a given height.
