Özet

A field study was conducted on a sandy loam soil in order to determine the response of tomatoes (H-2274 cv) to nitrogen (N) and potassium (K) applied with irrigation water through drip irrigation system or with conventional furrow irrigation. Treatments tested were as follows: a. Drip-fertigation (DF) : 84 kg N/ha, 105 kg K/ha, 17 kg Mg/ha, and 1.05 kg Fe/ha were applied with irrigation water throughout the growing season via a drip irrigation system. b. Furrow Irrigation (FI1) : In this treatment, the same amount of N and K were applied to the plant as in the DF treatment; (84 kg N/ha - 105 kg K/ha) c. Furrow Irrigation (FI2) : In this treatment, 220 kg N and 270 kg K per ha were applied to the plant.
