Abstract: A harvesting method for plants provides for harvesting one portion of the plant having a first nutritional content separately from the second portion of the plant having a second nutritional content. Desired nutritional contents may be achieved by varying the ratio of the two plant portions. The leaves of the plant often have higher protein content than the stems and may be stripped from the stems and harvested separately from the stems. Leaves may be allowed to regrow or the stems may be harvested at the same time. The mixing and matching of times of harvested leaves and stems, various ratios may be achieved. In addition, a percentage of the leaves may be removed and or the time that the leaves regrow may be varied to achieve the desired characteristics.

Abstract: A programmable viticulture management system includes a mechanized device for removing excess undesired portions of plants advances through a vineyard to perform control operations on two rows or half-rows of grape vines simultaneously. Accessories mount to the mechanized device and include various engagement members for engaging the vines. A control system automatically varies the velocity of the engagement members in relation to the vehicle speed. The control system also receives various inputs and provides information on multiple growth control practices.
