Leaf analysis as a means of determining the nutrient requirements of greenhouse tomatoes

, : Leaf analysis as a means of determining the nutrient requirements of greenhouse tomatoes. Acta Horticulturae (29): 81-88

Young, fully expanded leaves taken above the 2nd, 3rd, 4th and 5th trusses in March, April, May and June, respectively, were used for sampling and the total N, P and K contents were determined. The data obtained was used to determine the optimum rates of MIS-2 fertilizer (containing N,P,K and Mg) to be used on tomatoes grown on benches in sphagnum peat in quantities of 30 or 50 litres.
