Water productivity associated to the planting system in young Nadorcott mandarin plants





citrus, mulching, planting system, water productivity


The main goal of citriculture in Uruguay is to increase yield, quality, and improve sustainability and efficiency of natural resources. Today, it is not possible to conceive an efficient citrus production system without the use of irrigation technologies. The aim of this work was to evaluate the irrigation water efficiency and growth conditions of different plantation systems focused on speeding up production and the improvement of water use efficiency. An experiment was installed in Nadorcott mandarin with two planting densities (909 and 1220 pl. ha-1), and three plantation designs: ridges covered with white plastic cloth; uncovered ridges, and flat planting at ground level. At the end of the evaluation period, the volume of the trees planted in the covered ridges doubled those in the flat (1 m3). The trees on the flat design consistently produced fewer fruits and lower yield than those on ridges. Covered ridge showed the best performance. Soil water content remained higher and soil temperature lower in covered ridges. Overall, trees planted on ridges with or without plastic mulch allowed a better water use efficiency, and the lower soil temperature promoted a better environment for tree growth.
