A well written case study will follow a customer as they define a problem, determine a solution, implement it, and reap the benefits. Therefore, the objective of this study was to evaluate the growth and development of lettuce seedlings produced in granular rockwool, expanded per-lite and mixtures of both substrates during the The objective of this study was to determine whether hydroponically- grown lettuce contains as much ascorbic acid and tocopherol as soil-grown lettuce. monocytogenes in the field. The objective of this study was to evaluate the efficacy of Sanitization of Lettuce according to the protocols set forth by Iranian Ministry of Health and Medical Education for reducing populations of total coliform, fecal coliform, and helminth eggs present on lettuce.
