Green leafy vegetables, Aoba-type dishes in Japan, which is important, the more the country Thailand. Make the demand even more OBA. Price sold a 0.5 – 1 baht, but in the winter season, with short day length, the price will be higher, since OBA prototype from Aoba will bloom yield decreased OBA price is higher. Solution implemented by Aoba planted in conjunction with the use of light to increase the length of a day on which to grow plants in a greenhouse so popular, how to grow plants in the planting material. Provide water and nutrients in nutrient solution format because it offers greater than operating plants in the soil. Therefore, it has made an experiment to study the effect of concentration of nutrient solution formula Enshi on growth and yield of Aoba Aoba seeds by presenting green cards came to planting a seedling until the age of 1 month, and then move the planting material planted saplings, lint-free cloth, coconut. Inside the House, then let the nutrient solution formula, Enshi, different concentrations of 5 level is 2.4 1.8 3.6 3.0 and 1.2 mS/cm, respectively. It found that concentration 2.4 3.0 and 3.6 mS/cm, the height of most statistically significant. Concentration and 2.4 1.8 mS/cm, width canopy most statistically significant. Section 2.4 and 3.0 concentration mS/cm yield (the number of) the most statistically significant, but all levels of concentration, rate per day, OBA, the width is not statistically different.
