Integrated Crop-Nitrogen Management Improves Tomato Yield and Root Architecture and Minimizes Soil Residual N

Sustainable intensification of protected vegetable crops entails increasing yield while reducing environmental impact and labor input. To explore a comprehensive strategy for high yielding, highly efficient quality production greenhouse tomato (Solanum lycopersicum L.), an integrated crop-nitrogen management (ICNM) was compared to farmers’ traditional (TM) in field experiment solar greenhouse. A split-plot block design used. The main factor the ICNM TM. secondary four different basal fertilizer treatments, being control (CK; 0 kg N ha?1), carbon-based urea (BU; 100 controlled release (CU; conventional compound (CF; ha?1). An additional 200 ha?1 through drip irrigation as topdressing Tomato fruit yield, uptake, partial productivity with were significantly higher than TM, by 32.1%, 39.7%, 31.1%, respectively. proportion fine roots increased ICNM, average diameter decreased 10.7% There significant negative correlation between mean root uptake. In conclusion, beneficial form good system configuration, promote development shoot biological potential, increase maintain quality, reduce risks.
