Nitrogen, potash and magnesium nutrition of some vegetable fruit crops under glass.

Abstract

Different concentrations and proportions of N, K and Mg were applied as supplementary fertilizers to various crops through the irrigation system (strip spraying). Fertilizer containing 9 mol N, 4 mol K and 1.6 mol Mg/kg applied at electrical conductivities between 0.45 and 0.9 mS/cm at 25 deg C produced yields of up to 15.6, 19.7, 9.5 and 20.2 kg/m2 of tomatoes, cucumbers, sweet peppers and eggplants, respectively.
