Abstract: A computer controlled environment system and method are used to provide the optimum environmental and nutritional conditions for the growth and development of seed potato cuttings for the initiation and development of tubers that can be used as the seed source for further multiplication under field conditions as seed potato stock. Use of a controlled environment system and method that provides optimum cultural conditions results in rapid growth and development of the potato cutting so as up to six crops of tubers can be harvested in a calendar year.

Abstract: Disclosed are a method and an apparatus for irradiation of plants using optoelectronic devices. In accordance with this invention, optoelectronic devices that emit radiant energy at the appropriate wavelength are operated in a continuous mode or pulsed asymmetrically at a frequency and level of electrical power that results in sufficient irradiance to support plant growth and development. The apparatus consists of: (1) an array of optoelectronic devices, primarily light emitting diodes, for producing irradiance in each of three different wavelength regions necessary for specific plant photobiological reactions, (2) a pulse generator and associated electric power driving components, and (3) an electric direct current (D.C.) power supply.
