Abstract
Rice cultivation in a continuous flooding system is common practice. However, due to the scarcity of continuous irrigation alternate water management strategies are being explored for rice cultivation. The objective of this study was to evaluate the effects of alternative water management strategies and nitrogen fertilizer on rice yield grown on highly organic (histosol) soils.
Highlights
Rice is traditionally grown under continuous flooding (CF) conditions
The objective of this study was to evaluate the effect of alternative water management strategies and N on rice grown on organic soil in the Everglades Agricultural Area (EAA) of South Florida
Neither of the treatments affected rice yield cultivated on Histosols
Summary
Water scarcity in recent years has increased the restriction of agriculture production, and there is need to developed alternative systems that required less water [1]. Several studies reported resource conservation technologies can be used to grow rice under less water [3,4,5,6]. Alternative wetting and drying (AWD) [4,7,8,9] and single mid-season drying (SMD) [10,11] are commonly practiced alternative water-saving practices adopted in the rice production system. Under AWD, fields are subjected to alternate wet and dry rather than continuous flooding. The field is allowed to dry for 1 or 2 days and re-flooded. The success of AWD and SMD depends on climatic conditions, rainfall, and soil types [12]
