1998
Satugaitis, G. (Lithuanian Institute of Horticulture, Babtai (Lithuania))
In unheated glass greenhouses of Lithuanian Institute of Horticulture paprika was fertilized by different rates of nitrogen, phosphorus, potassium and magnesium. Nitrogen and phosphorus fertilizers increased productivity of paprika while potassium and magnesium fertilizers did not produce any effect on it. Impact of fertilizers was mainly determined by nutrients content in the soil of greenhouse. It was established in water extract by volume method at the ratio 1:2. The highest yield of paprika was obtained when after fertilization in water there were found soluble nitrogen (N) 40-60 mg/l, phosphorus (P) 15-20 mg/l, potassium (K) 80-120 mg/l and magnesium (Mg) 20-40 mg/l. Higher nutrients contents in the soil did not increase paprika yield.
