LEAF ANALYSIS AS A MEAN OF DETERMINING THE NUTRIENT REQUIREMENTS OF GREENHOUSE TOMATOES

Early tomatoes are often grown in Poland on benches where the amount of soil for plants is limited.
In recent years sphagnum peat moss is commonly used as a substrate for greenhouse tomatoes.
Growing tomatoes in sphagnum peat moss, Pudelski (1967) obtained the highest yields when N:P₂O₅:K₂O ratio was 1:2:2.

The paper presents the data on the effects of different doses of macronutrients added as mixed MIS-2 fertilizer on tomato yields and nitrogen, phosphorus and potassium content in tomato leaves.
