Hochmuth (1998) reported that Megafol spray treatments had not effect on lettuce yields, head size, firmness, tip burn and internal stem length.Also early lettuce growth, early plant vigor and lettuce leaf nutrient concentration at harvest were not affected by Megafol sprays.Masarirambi et al. (2010) studied on effect of organic fertilizer (bounce back compost, cattle manure and chicken manure)and inorganic fertilizer on lettuce yield and quality. They found that type of fertilizer significantly affected growth, yield and nutritional quality of lettuce. The chicken manure exhibited relatively higher values on number of leaves, plant height, marketable yield and mean leaf dry mass.
