Wide-bed cotton planting under irrigation

Ivan Saldziev, Svilen Raykov

Abstract: The aim of this study was to make a comparative assessment on Bulgarian condition of cotton irrigation regime under tree norms – 1200, 900 and 600 mm/ha. The cotton was cultivated on two systems: the first one on interrow-spase 60 cm, and new system – under 80 cm interrow-spase. It was determined that the cotton planted under 60 cm interrow-spase on 1200 and 900 mm/ha showed better yields and the best economical results. Irrigation norm of 600 mm/ha under wide-bed system realized bed yield and low economical effects.
