Lettuce is a fast-growing crop, which means you cannot afford any delay or mismanagement. Any stress or lack of nutrients will change the plant’s physiology and there will not be enough time for recovery. As a result, both yield and uniformity will suffer. A common problem is a lack of nitrogen (N) in the early growth phase. Because the lettuce seedlings are planted in moist soil and thereafter irrigated frequently to get them established, there is plenty of water in the soil and this causes the available nitrate to leach away below the roots, which are very shallow at this stage. This problem is compounded by rain.
