Due to poor soils and high minimum temperature (above 20.5o C), the ‘Sertão’ region, located in the Brazilian Semi-arid Northeast, is probably one of the harshest cropping environments in the world, in which nopal i s grown for f odder production. Recently, another problem appeared, the armored scale insect (Diaspis echinocacti - Bouchè). A field trial with twenty varieties was started in April 2000 in Petrolina, Pernambuco, (average rainfall 552.2 mm, 80% available in December through April). The varieties tested were: three local cultivars, ‘Gigante’, the most cultivated, ‘Redonda’ (both Opuntia ficus-indica) and ‘Doce’ nopal (Nopalea cochenillifera) and Clone IPA- 20, eight varieties of highest performance in a preliminary evaluation2, that are identified by a number such as, 1258 - Additional Cv.; eight varieties provided by IPA, and identified by a number such as, IPA-90-73, and n ever tested in the region.. The e xperimental design was, a randomized complete block, with four replications, in p lots of 3.5 m2, made up o f one seven-plant li ne, for evaluation, on ly five plants/line were c onsidered. Planting density was 20.000 p lants/ha. Manure was applied on biannual basis at the rate of 2.86 kg/m.. Weeding was done with hoes. In May 2004, the first harvest was done, collecting all fresh material except t he basal pad and the first l ayer of pads. Annual fresh matter (FM) production was calculated d ividing total yield by four. Mean production was 75.24 ± 33.61 ton FM/ha/year (CV = 44.7 %). The eight most productive varieties, with FM production/ha/year, h eight and transversal canopy diameter in p arenthesis were: 1258 - Additional cv. (115.25 ton; 1.50 and 0.96 m); IPA-90-73 (106.75 ton; 1.53 and 1.16 m); Clone IPA-20 (101.12 ton; 1.46 and 1.09 m); 1278 - Mexico Fodder (99.00 ton; 1.68 and 0.88 m); IPA- 90-155 (96.75 ton; 1.50 and 1.05 m); IPA-90-75 (86.92 ton; 1.32 and 1.00 m); 1311 - Marmillon Fodder (85.55 ton; 1.64 and 0.78 m); 1267 - Algeria Fodder (85.25 ton; 1.18 and 1.18 m). ‘Gigante’ nopal (68.00 ton; 1.43 and 1.05 m) stayed in 13 o position, as in research cited b elow. There was no d ifference (P<0.05) among these treatments, du e to h igh CV. Other data, such as, protein and fiber levels, that are still under analysis, might indicate that highest production does not assure the best variety for the region.
