Substandard and Semi-Dwarfing Citrus Rootstocks for More Intensive, Higher-Density, and Sustainable Plantation Systems

An increasing number of intensive, dense, and sustainable citrus plantations have fostered a growing interest in addressing the future challenges crops: increase world’s population, climate change, globalization. Nutrient efficiency absence vigorous rootstocks are required for success these plantation systems. The agronomic performances ‘Lane Late’ orange cultivar on three substandard or semi-dwarfing (Forner-Alcaide no.5 (FA5), Forner-Alcaide no.13 (FA13), no.41 (FA41)) were evaluated Spain comparison with more traditional Mediterranean (Carrizo citrange (CA), Citrus macrophylla (MP), ‘Cleopatra’ mandarin (CL)) under poor mineral fertilization program over six seasons. FA13 FA41 induced smallest trees. Although rootstock did not induce significant effect yield (kg m−3), highest values recorded MP, CL FA13. In this sense, showed high productive potential ha−1), given possibility narrowing tree spacing (smaller size). Regarding use soil nutrients, was most efficient rootstock. Thus, stands out as suitable intensive systems conditions similar to those study.
