The effects of leaf removal and of modifying temperature set-points with solar radiation on tomato yields. Therefore, the optimal leaf removal method is to remove all leaves until only one leaf remains above the truss where harvesting begins during either the hot or winter season.Īdams, S.R., G.C. Similar to the hot season experiment, the Start-H treatment had the best results in respect to yield and harvest rates. In the winter experiment, only three of the methods of leaf removal were tested: Leaf-14, Start-H, and End-H. The 7-Weeks method had results similar to those of Start-H, but its application was inconvenient. The Start-H method was the optimal leaf removal method. Thus, leaves must not be removed if the harvest rate is fast.
Total yields decreased following leaf removal when the harvest rate was fast (3–4 days per truss). The desirable harvest rate was 6–7 days per truss. Leaf removal did not affect the flowering rates very much, but influenced the harvest rates and yields greatly.
In the hot season experiment, four methods of leaf removal were tested: removal of all leaves more than 14 from the growing tip (Leaf-14), removal of leaves until only one leaf remained above the truss where harvesting begins (Start-H), removal of all leaves below the truss 7 weeks after flowers bloomed (7-Weeks), and removal of all leaves below the truss where harvesting was completed (End-H). We investigated removal methods that are easily applicable to tomato cultivation during summer and winter harvesting periods. The optimal degree of leaf removal varies based on environmental conditions, such as seasons. Tomato yields and quality can be improved by the removal of some leaves attached to the tomato vine.
