Effect of Drip Irrigation, N-Fertigation and Cultivation Methods on the Yield and Quality of Carrot
2007
Dyśko, Jacek | Kaniszewski, Stanisław
In the years of 2004-2006 research on influence of surface and subsurface drip irrigation on yield and quality of carrot grown on ridges and on the flat ground was investigated. Irrigation was started at soil water potential of 30-40 kPa. Nitrogen fertilizers (100 kg.ha⁻¹) were applied in two rates. The first rate was preplant applied, the second was used by fertigation. In the control treatment without irrigation, the second rate of nitrogen was applied by broadcasting. Surface and subsurface drip irrigation significantly increased the yield of carrot. In cultivation on ridges higher yield of the carrot was obtained when surface drip irrigation was applied as compare to subsurface method. Carrot cultivated on ridges produced significantly longer roots than cultivated on flat ground. Generally the surface and subsurface drip irrigation decreased dry matter content and total N content in carrot roots. Drip irrigation at both cultivation methods increased pH and decreased the salt concentration of the soil.
