As the synthesis or absorption of many nutrients is light dependent, the lower nutritional value of crisphead lettuce is due to the enclosure of its leaves in a head structure. In addition to varietal differences, nutritional quality of lettuce may be influenced by environmental factors such as ...
Introduction California ranks first among the states in the commercial production of lettuce (Lactuca sativa L.), averaging slightly over 60 per cent of the national monetary value (Dean and McCorkle, 1960); (Hoos and Phelps, 1948).4 Spring, summer, and fall production is concentrated in the...
However, growth responses of lettuce to single addition of P or Fe into diluted biogas slurry were not significant. In addition, supplementation of P and Fe improved leaf chlorophyll content (determined as SPAD value), nitrate concentration significantly or slightly of the lettuces but not vitamin...
Maintaining AMF and rhizobial symbioses are expensive to the plant in terms of supplying sources of carbon from photosynthesis, and as such the symbioses are tightly regulated by the availability of nutrients, particularly N-availability in the regulation of nodulation and P-availability in the regula...
some vegetables need higher concentrations. For example, kale and spinach are relatively “heavy feeders” compared to lettuce. The optimal nutrient formula and concentration also vary among cultivars of the same crop, such as lettuce with its different and distinct genetic variability and nutritional ...
For some people, this may be easy to accomplish–for example, by switching from iceberg lettuce to romaine lettuce, or increasing the relative proportion of vegetables and fruits in the diet compared to traditional snack foods. For other people, this may necessitate reversing prior lifelong trends...
Leafy greens include spinach, kale, micro greens, collard greens, Swiss chard, arugula, watercress, romaine lettuce, and more. Leafy greens are a nutrient powerhouse, full of a variety of nutrients like folate, iron, lutein, vitamin K, and beta-carotene. ...
In the Beijing area, some people have tried to rely on calcium in hard water to satisfy the growth requirements of lettuce. In general, the use of hard water below 15 degrees for soilless cultivation, better hardness of hard water can not be used as soilless cultivation of water, especially...

Vegetables, both unsweetened and unflavored, included fresh or refrigerated vegetables, such as bagged or packaged lettuce and salad blends, fresh baby carrots, carrot sticks, whole carrots, celery, heads of lettuce, tomatoes, or mushrooms; frozen vegetables, such as, e.g., broccoli, carrots, ...
