Analysis of agricultural production systems of hydroponic tomato in Morelos state of Mexico, through a systematic approach, called systems development of life cycle （SDLC） was performed by comparing this with the methodology known as life cycle assessment （LCA）. This permits to analyze the differences in approaches of all these methodologies to propose improvements in the current system, which can allow an improved assessment of the environmental quality of agricultural products, which often is subject to confusion. That due to measurement parameters are not generally accepted by society, producers and consumers, may ensure that the process is fully sustainable and is considered quite as a green technology processes towards an ecological benefit and therefore for the humanity.

The tomato is one of the horticultural crops of the greatest economic value;for this reason, flexibility of management is usable. The population density in a crop of vegetables is determined by the distance between the plants and so it is necessary to choose the number of plants per square meter since the saturation of plants will lead to competition between sunlight, nutrients and weed. The objective of this work is to make the appropriate investigation for the use of the model proposed in order to describe the growth of tomato in greenhouse to high density of two plants per container to two bunches per plant, resulting in eight plants per square meter to grow, by means of a simulator of growth by computer. Of this work, it is concluded that it is possible to use the model to describe the growth of plants, and in the near future it will be possible to develop a simulator by computer of the growth of these crops in order to improve their quality and increase their production.

Life Cycle Assessment of Hydrogel Used in Hydroponics for the Impatiens New Guinea Production

The environmental impact on the planet leads to the search of new processes that are friendly with the environment and obtaining high quality products. In this sense, green chemistry is used in the generation of products through processes that do not affect the planet. In many of these processes and in general, the use of water has been depleted this resource of vital importance for the survival of living things. In Mexico, 77% of water is used in agriculture;14% in the public supply;5% in the thermoelectric plants and 4% in the industry. In research presented, hydroponics is essential in the process and is defined as a technique used to reduce excessive water consumption, by providing the necessary nutrients, in addition to preventing soil erosion by allowing the growth of plants without use of ground. The potassium polyacrylate is a super-absorbent polymer (Hydrogel) capable of absorbing water up to 500 times of its weight and has a life span of 10 years. When mixed with a substrate, the required nutrient solution potassium polyacrylate allows to lengthen the interval watering and thus reducing the consumption of water from plants. Morelos is the largest producer of ornamental plants in the country, due to its privileged climate and location. In the present work using the hydroponic methodology, we planted cuttings of Bethlehem New Guinea (Impatiens New Guinea) in a substrate made by 60% of coconut fiber, 20% tepojal, 20% ground sheet mixed with polymer of potassium (20 g per litre), 400 ml of Steiner nutrient solution in concentrations of 40%, 60%, 80% and 100%, varying the interval of 3-, 6-, 8- and 10-day watering. The variables considered are: concentration of chlorophyll, the plant height, leaf area, number of stems and weight dry total. The 12 principles of green chemistry applied to hydroponics using polyacrylate of potassium as part of the substrate in Bethlehem New Guinea (Impatiens New Guinea) to determine the analysis of life cycle (LCA), doing the bala
