Resumo: |
The latosolic Concretionary Petric Plintosol is the less fertile soil in the bioma Cerrado. Making it to produce food in order to contribute to the Brazilian agribusiness, turns into a great challenge for Science. In addition to this fact, the\pineapple fruits exports are important incomes sources for our Country. For this reason, the present work aimed to assess effects of application, on soil, of calcium carbonate, calcium & magnesium carbonate and calcium sulfate, on productivity of pineapple plant (Ananas comosus L. Merril) var. Pérola cultivated in typical Distrocohesive Yellow Latosol and latosolic Concretionary Petric Plintosol on a same topossequence of Cerrado bioma. Soon after planting, it were applied on both soils, the following equivalent doses\(kg ha-1): on the latossol area – 2000, 2000 and 1000; and on the plintossol area – 3000, 3000 and 1500; of calcium carbonate, calcium & magnesium carbonate and calcium sulfate, respectively. As effects, the fruits production averages (t ha-1), in both soils were: 8,32; 12,94; 13,82; 15,09; 5,02; 12,60; 14,11; e 14,82, respectively, in the same sequence above. The essays were set up in 2010, in a region of Anápolis, Goiás State, latitude 16º19ˈ 36 ̎ S, longitude 48º57ˈ 10 ̎ W and altitude 1017 m. The yearly pluviosity average is 1.200 mm, and the temperature oscillates between 21 and 35ºC; the climate is classified as Aw according to Köppen system. The harvest was achieved in 2012. The experimental design was in randomized blocks. Each plot measured 1,20 x 6,60 m and were four the number of treatments with five replications. The three products, in the mentioned equivalent doses, induced the latosolic Concretionary Petric Plintosol studied to reach a pineapple Pérola production capacity equivalent to the typical Distrocohesive Yellow Latosol. Calcium sulfate, calcium carbonate and calcium & magnesium carbonate, individually, increased the tenor of changeable bases in the upper layers of both soils, wich made it possible to obtain greater pineapple Pérola yielding. |
