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.

In a factorial fertilizer trial with 3 levels of N, P and K on pot-grown 1-year-old Golden Delicious apple trees, correlations were found between the N and K contents of the leaves and the soil. There was also a positive correlation between the N...

In pot experiments using an alluvial meadow soil, 40, 80 and 120 mg N, P2O5 and K2O/g soil were applied to 1-year old apple trees. Analysis of leaf samples taken from early to mid-August indicated a positive correlation between leaf N content and...
