Abstract
The spectrum of materials known to be absorbed by plant foliage has become exceedingly broad. To determine, the effect of different levels of nitrogen and potassium solution on the yield and quality of tomato, a two factor completely randomized experimental design (CRD) with three replications was conducted with `Maha` cultivar in an unheated plastic tunnel. Nitrogen and potassium solution from the source calcium nitrate and potassium phosphate were used with an amount of 4, 6 and 8 and 2, 4 and 6 mmolL-1 respectively. Results of presented experiment revealed different effects of calcium nitrate and potassium phosphate as foliar nutrition and the interaction of these fertilizers on the yield and quality of tomato. The results of this experiment demonstrated that tomato crops fertilized with 6 mmolL-1 calcium nitrate and 4 mmolL-1 potassium phosphate contained greater quality.
Key words: Nitrogen, potassium, foliar nutrition, yield, quality, tomato.
