IMPROVING PRODUCTION YIELD OF LONG PEPPER CROP GROWN IN UNHEATED SOLAR THROUGH SUSTAINABLE FERTILIZATION

Abstract

Pepper (Capsicum annum L.) is a cultivated legume species belonging to the Solanaceae family, widely cultivated in many regions of the world, due to its important nutritional and economic qualities. Adequate plant nutrition plays an important role for vigorous growth, increased production yield and fruit quality. This study aimed to identify essential elements for the nutrition of a long pepper crop established in an unheated solar, in the Dobreni locality, Giurgiu county. In this regard, soil samples were taken both before the establishment of the crop and after its dismantling. The analysis of the first soil sample recorded a low ammonium content, high amounts of sodium, calcium, phosphorus, nitrates and nitrites. Fertilization recommendations were made to correct the amounts of the main nutrients analyzed. After applying the recommended fertilizers, a soil sample was taken again to compare the results with the first sample.
