Resumen
CASTRO NAVA, Sergio y HUERTA, Alfredo J.. Response of sugarcane varieties (Saccharum officinarum L.) to NPK fertilization on dry land in southern Tamaulipas, Mexico. Rev. Mex. Cienc. Agríc [online]. 2015, vol.6, n.spe11, pp.2225-2232. ISSN 2007-0934. https://doi.org/10.29312/remexca.v0i11.804.
The aim of this study was to identify the optimal economic dose for NPK that optimizes yield in the field and juice quality of sugarcane in the area of influence of the engenho San Miguel del Naranjo in Tamaulipas, Mexico under dryland conditions. The varieties CP 72-2086 and Mex 79-431 in “soca” cycle were evaluated during the 2010-2011 in two locations under dryland. For generating the treatments, we used the San Cristobal design (41, 51, 60 and 69; K: P 103, 112, 120 and 128 N 46, 58, 70 and 82 kg ha-1), in addition of the unfertilized control. The 13 treatments were distributed in field, in accordance under a randomized complete block with four replications. The 103-41-46 dose was sufficient to meet the nutritional requirements of the two varieties with an average yield of 112.2 Mg ha-1, since higher N yields were shot down. Fertilization doses recommended by the engenho (120-60-70) is not adequate for the studied varieties and soil type, suggesting further research in the area. The fertilization did not change the °Brix of the juice of the cane, indicating that the dose 103-41-46 allows increased throughput and maintain the quality of the juice.
