| Summary: | Sugarcane (Saccharum officinarum L.) is a primary carbo-hydrates source for panela; in Colombia the main panela re-gion is located in the Hoya del Rio Suarez, however, it has not been consolidated a production sufficiently profitable, com-petitive and environmentally friendly production. One of the most decisive aspects in the production of panela is mineral nutrition, due to the fact that it is currently done in a con-ventional way without knowing the levels of extraction of the genetic materials used. The objective was to determine the nutritional requirement, production of biomass and produc-tivity in second cut in the municipality of Suaita (Santander), the design used was blocks at random, with 3 treatments (the varieties CC 93-7711, CC 93-7510 and RD 75-11) and 5 repetitions, 4 samplings were made at 118, 252, 335 and 392 days after cutting (ddc). It was observed that the highest absorption of N, Ca and Mg occurred at 335 ddc, while for P and K, occurred at 392 ddc; nutrients accumulated es-pecially in the stems; CC 93-7711 outperformed the other varieties with a total absorption in kilograms per hectare of 448 N, 296 K, 85 Ca, 43 P and 40 Mg, followed by RD 75-11 that presented approximately 16% less in N-K-Ca-P-Mg, the nutrient absorption pattern was N>K>Ca>P>Mg and as for productivity, RD 75-11 stood out, then CC 93-7711 and CC 93-7510 with 172.6, 171,1 and 159.9 tons of cane per hec-tare, respectively. |
