Sulphate Mn granules (Microman ®) and chelated Mn (MF-Mn®) were used as sources. We used a split-plot, randomized complete block design with four replications per treatment. The variables studied were: weight and number of tubers per category. The results show that the application of both soil and foliar Mn exerts a positive response in the criolla potato, with increases of 52% in commercial yield and more than 100% in first category yield with respect to traditional fertilization. The optimal dose is between 1.5 to 2.0 kg ha-1 for both soil and foliar Mn, with an economic optimum between 0.8 to 1 kg ha-1 Mn, edaphically applied. The results showed no differences between the techniques of foliar and soil application for yield potential, but did for number of tubers.</span></span></span></p></span>http://www.revistas.unal.edu.co/index.php/agrocol/article/view/29782 |
