ZAMORA, Frank R; SANCHEZ GUTIERREZ, Alexander  e  TUA, Domingo. Biometric evolution of two potato varieties, in the high zone of the state  Falcon, Venezuela. Agronomía Trop. [online]. 2008, vol.58, n.1, pp.41-43. ISSN 0002-192X.

In order to offer agronomic alternative to the small farmers of the Federation council, Falcon State, two varieties of potato were evaluated, S. tuberosum L.; Kennebec (VK) and Atlantic (VA), in the Sabanita area, located to 800 meters up sea level, characterized as premontain humid forest, with precipitations of 1000 mm per year and structured soils with mean levels of organic matter. The experimental design used was random blocks with three repetitions, the variable evaluated were: plant height (PH), stem thickness (ST), stem number (SN); also biometric parameters were evaluates such as: tuber number (TN), plants weight (PW), fresh weight (FW) and dry matter (DM), yield by plant (YP) and yield by hectare (kg ha-1). For both varieties the (TS) was similar (P>0,01), while the parameters; NTP, PTP, RP and Rha showed significant differences (P<0,01) between the varieties evaluated, being superior VK. A high productive potential demonstrated by VK, suggest that this variety is an alternative in the diversification of the traditional production systems of the high zone of the state Falcon.
