Response from wheat (Triticum aestivum L.) cultivars to aluminum content for the soil - DOI: 10.4025/actasciagron.v29i5.746

Abstract

Nine wheat cultivars were carried out under three different soil fertility conditions, without exchangeable aluminum nor fertilizer (I), with exchangeable aluminum but without fertilizer (II), and without exchangeable aluminum plus 250 kg ha^-1 of 4-20-20 fertilizer formula (III) for 2001/2002 harvest. Plants' height, hectolitric weight and productivity were recorded. Significant differences were observed at 5% using the Tukey test, concluding that fertility treatments interfered on the evaluated parameters. For the first treatment, BRS 49 cultivar was recommended. For treatment II, IAPAR 53 cultivar presented better performance. As for the third treatment, CD 105 cultivar was recommended. OR 1 cultivar, on the other hand, was not recommended, since it presented the lowest productivity. Finally, results showed that treatment II presented better productivity than treatment I, probably because of its great percentage of organic matter, which, sometimes, can inhibit aluminum. Average productivity was recorded as the highest in treatment III.
