There is little information on the availability of soil mineral nitrogen (N) in organic greenhouse tomatoes after the application of mobile green manure (MGM) and its effect on plant nutrient status and yield. Taking into account this knowledge gap, the influence of legume biomass from outdoor-grown broad beans (FAB) or two different doses of feed-grade alfalfa pellets (AAL = 330 gm -2; AAH = 660 gm -2) on MGM The nutrition and yield of organic greenhouse tomato crops were evaluated.
Compared with the untreated control, all MGM treatments increased the mineral N concentration in the soil during the entire planting period, as well as the total N concentration in the tomato leaves. Among all measurement parameters, FAB and AAH processing have a stronger influence than AAL processing. In addition, compared with the control, the AAL, AAH, and FAB treatments increased yield by 19%, 33%, and 36%, respectively.
MGM, whether used as a fresh biomass of broad beans or as dried alfalfa pellets, is used in organic greenhouse tomatoes to significantly increase plant soil available nitrogen, improve nitrogen nutrition, and increase fruit yield. However, in the early stage of planting, the nitrogen mineralization rate after applying MGM was too high, and thereafter it decreased significantly. This may cause nitrogen deficiency in the later stages of the crop.
