Agro-economic yield of taro clones in Brazil, propagated with different types of cuttings, in three crop seasons

Abstract

The experimental studies were conducted in 2007-2008, 2008-2009 and 2009-2010 crop seasons, in order to know the agro-economic yield of 'Chinês' and 'Macaquinho' taro clones, propagated using huge, extra, large, medium, small and tiny cormels. The harvest was done on average on 202 days after planting, in three crop seasons. Based on the joint analysis of variance carried out, it was observed that taro clones showed signifi cant differences in the yield of fresh and dry weight of leaves, cormels, and commercial and non-commercial comels; besides, there were signifi cant differences in yield of a crop season to another and the size of the cuttings induced signifi cant differences in yield. In the conditions that the experiments were conducted, and considering the highest average yield of fresh weight of commercial cormels (28.69 t.ha -1 ) and highest net income (US $14,741.14) correspondent to the three crop seasons, it is recommended to cultivate 'Macaquinho' clone using small cuttings in propagation.

“…Trata-se de uma rizomatosa rica em amido, apresenta grande produção por unidade de área e baixa demanda por mão-de-obra (Heredia Zárate et al, 2009). Destaca-se ainda como uma cultura de baixo custo de produção e pouco exigente em fertilidade do solo e insumos (Heredia Zárate et al, 2013). Além disso, é uma planta tolerante à restrição parcial de luz (Gondim et al, 2007), sendo tradicionalmente cultivada em alguns países em consórcio com coco, milho e com outras culturas (Rubatsky & Yamaguchi, 1997).…”

“…Pesticides application is also affected since some pests are more prevalent in the dry than during the wet season and vice versa, while fertilizer applications are affected by excessive rainfall (loss through runoff and leaching) and drought (less solubility in the soil and limited nutrient availability for the plants). The time of the year or season to plant taro varies from country to country; however, planting taro in the rainy or wet season seems to produce higher yields [17][18][19][20].…”
