same sized seedlings will be transplanted to the 6̋˝ round pot filled with peat moss media (MetroMix 360, SunGro Horticulture, Vancouver, Canada). Two different fertilizer regimes will be selected for nutrient sources of lettuce cultivars. The elevating fertilizer regimes will be tested if the nutrient densities of the lettuce crop increases through cultivar selection and nutrient management. Two fertilizer regime will be Jack’s 20-10-10 Peat-Lite commercial fertilizers (Jack’s Professional Fertilizers, J.R. Peters, Inc., Allentown, PA) and organic fertilizer (Pure Blend Pro Grow 3-1.5-4, Botanicare, Tempe, AZ) with varying concentration of Ca for this experiment. The goal of the application of different fertilizer regimes with varying concentration is to determine the nutrient densities of the lettuce through cultivar selection and nutrient management. The lettuces will be grown in the greenhouse for about 4-5 weeks from transplanting to marketable size. Each regime of fertilizer will be divided into three treatment groups based on varying internal nutrient concentration. The first fertilizer regime will be contained N, P, K, and micronutrient composite from a Jack’s 20-10-10 Peat-Lite commercial fertilizers with varying Ca (200, 300, 400 ppm) as CaCl2. Another fertilizer regime will be obtained from organic fertilizer with varying amount of Ca (200, 300, 400 ppm) as CaCl2. Three treatments of each group of fertilizer regime will be tested for this study. Therefore six treatments will be selected in two groups of fertilizer regimes. The treatment will be applied in one day interval at 100 ml/plant for first week then at 200 ml/plant until harvest.
