| contents | Effect of edaphic and foliar applications of different doses of zinc on the yield of the Criolla Colombia cultivar Andrés López Manuel Iván Gómez Luis Ernesto Rodríguez Agrociencias tubers Andean crops Fertilization diploid potato micronutrients The present study was carried out in a Typic Hapludand soil in the municipality of ‘El Rosal’ (Colombia) and aimed to compare the yield performance of the cultivar Criolla Colombia under foliar applications of Zn chelate (0, 1, 2 and 3 kg ha-1) and edaphic applications of granulated Zn sulfated (0, 1, 2 and 3 kg ha-1). A split-plot, randomized complete block design, with four repetitions per treatment, was employed. In each category, the evaluated variables were: tuber weight and number of tubers. The results revealed that the 3.0 kg ha-1 edaphic application rendered a quadratic yield behavior with a relative increase of 7.9 t ha-1 (136%) for the first category tuber weight and 9.5 t ha-1 (68%) for total weight. In turn, the foliar application of the same dose resulted in a 5.8 t ha-1 (93%) relative increase and a first category tuber total weight increase of 3.8 t ha-1 (24%). Under the edaphic and foliar Zn applications, the number of tubers underwent 77 and 86% increases, respectively, with respect to the control. These results show the importance of Zn in photoassimilate accumulation efficiency, structure differentiation and tuber quality in this short-cycle crop. 2014 artículo científico 0120-9965 https://www.redalyc.org/articulo.oa?id=180330697010 es http://www.redalyc.org/revista.oa?id=1803 Agronomía Colombiana application/pdf Universidad Nacional de Colombia Agronomía Colombiana (Colombia) Num.1 Vol.32 |
