Improvement of Vegetable Crops Cultivation Technology by Applying Biostimulant in Protected Area

Abstract

In 2017-2019, during the winter-spring crop rotation period the effect of organic biostimulant Fulvit on the tomato variety “Lusarpi F1”, cucumber varieties “Nazrvan 45”, “Nare” and on the sweet pepper varieties “Loshtak” and “Narinj” have been studied in greenhouse conditions. The fertilizer was introduced through foliar application method in nutritional form with 1/100 dosage, 3 times with 10-15 days’ intervals. The research results have revealed that in comparison with the control variant in the rest investigated varieties Fulvit fertizer has promoted the plants growth and development; it has also improved the fruit and seed quality as well as yield capacity and profitability.
