Agricultural production begins with photosynthesis in green plants, which require water, solar energy, and carbon dioxide. It happens through the plant's ability to utilize of solar energy In the fixating carbon dioxide in the atmosphere into carbohydrates. The energy obtained used to biosynthesis, including essential amino acids and proteins. The materials used for agricultural production with little initial cost. However, when observed as an economic activity, carbon dioxide fixation, photosynthetic efficiency was very low, mainly because usage solar energy in green plants of the low utilization rate. Therefore, an integrated approach there is a need to increase the level of solar energy use by plants as the largest amounts of carbon dioxide into the atmosphere and converted into useful substrates.
Although utilization rate of solar energy by plants have been estimated theoretically between 10%-20%, the actual rate is usually less than 1%. C4 and some plants, such as sugarcane, with very high photosynthetic efficiency, and rarely exceed the utilization rate of 6 or 7 percent during the maximum growth period. The utilization rate is typically less than 3% even for crop yield optimization.

"An ideal agricultural system is sustainable, maintains and improves human health, benefits producers and consumers both economically and spiritually, protects the environment, and
produces enough food for an increasing world population."- Dr. Teruo Higa
The photosynthesis efficiency of the chloroplasts cannot increase the host crop plants any other; this means that biomass production has reached maximum leve1. Therefore, a better chance increased production of biomass somehow using visible light, which you cannot currently use chloroplasts, infrared radiation; together, these include about 80% of total solar energy. Also, you should explore ways of recycling organic energy contained in plant and animal waste through the direct use of organic molecules by plants.

Thus, it's hard to go beyond current limits for crop production only if efficient use of solar energy further, the potential energy in the current organic molecules (the amino acids, peptides, carbohydrates) is used either directly or indirectly by the plant. This approach can help to solve problems of environmental pollution and deterioration due to misuse and excessive application of pesticides and chemical fertilizers to soil. Therefore, new technologies that can enhance the economic viability of farming systems with little or no use of pesticides and fertilizers are sorely needed, and It should be a high priority for agriculture research both now and shortly the future.
