- Abstract
The objective was to evaluate the growth of clones of forage cactus, subjected to different conditions of water availability in the Brazilian Semiarid, during a year of climate anomaly (biennium 2012-2013). The experiment was carried out in the first production year of the second crop cycle (March 2012 to February 2013), in the district of Serra Talhada, State of Pernambuco. The experiment was carried out in a randomized block design using a factorial arrangement 3x3 with three replications, being used three intervals of application of a fixed irrigation depth (7.5 mm), (7, 14 and 28 days), and three forage cactus clones (IPA: IPA Sertânia; MIU: Míuda and, OEM: Orelha de Elefante Mexicana). Eight biometric campaigns were performed during the experiment period for morphological analysis of the plants and cladodes along the time. It was found that water availability conditions showed no significant influence (P>0.05) on the majority of the absolute and relative values of the growth variables of the three forage cactus clones. However, when comparisons were performed among different clones, regardless of the water availability conditions, it was observed that, in terms of absolute values, the OEM had the highest means, differing only from the MIU clone. Regarding evaluations over time, there were increased growth rates in the last months of the crop cycle because of the occurrence of rainfall, which in conjunction with the application of the irrigation treatments promoted the best biometric increments for the OEM and IPA Sertânia clones.
