HEAD LETTUCE This production summary provides an overview of head lettuce growing, harvesting, and post harvesting practices. Seedlings can be grown in a range of acceptable substrates. Make Nursery beds 100 cm wide and 30 cm in height. Measurements of root length and biomass in cores were used to estimate totals per m2, based on calculations derived for each type of management system. Although lettuce is produced in many states, California and Arizona dominate U.S. production. capitata). About 6 oz of seed and 300 square feet of bed space is needed to grow transplants for 1 acre. The plant is diffic… The focus of this profile is on the key management issues associated with producing and marketing greenhouse vegetables in Alberta. Root characteristics were measured during the pre-harvest period of maximum water and N uptake at the four sites and included root biomass, N allocation and root length density in depth increments to 75cm. Of fundamental importance to hydroponic lettuce production are the physical components of both the germination area and the pond area. Roots were most abundant in the top 50 cm of soil; root length density decreased to < 0.5 cm cm−3 below this depth in all management systems. According to the figures available, millions of tonnes of lettuce are grown annually worldwide. In 2013, 24.9 million tons of lettuce were produced in the world. For growing lettuce,  150-200 q/ ha of farmyard manure add 25 kg of both  Nitrogen and potassium and 90 kg of phosphorus per hectare.

Lettuce is a cool-season crop that grows best with moderate daytime temperatures (73oF) and cool nights (45oF). The application of fertilizers influences the growth and yield of lettuce. Objectives of this study were to describe lettuce (Lactuca sativa L.) rooting patterns under actual management practices in growers' fields and to relate rooting patterns to soil NO3 −-N distribution in lettuce production systems. Image of lettuce, production, manufacture - 9505429 Much of the commercial lettuce breeding is focused on outdoor field production. The response of lettuce root distribution to availability of water and N in the top 50 cm of the profile suggests that lettuce can potentially increase its capacity for N uptake in N3 −-N enriched soil zones. There is no question that the production of greenhouse grown lettuce and greens is evolving as the opportunities and demand expand and mature.
