Abstract

The objective of this paper is to evaluate the resistance to soil penetration in an area with six successions of cultures, involving the double cropping cultures and corn, in no-tillage management, carried out for three years in Rio Verde, Goiás. The experiment was conducted in 1995. The used double croppings were: corn (Zea mays L.), soy (Glycine max L.), sunflower (Helianthus annus L.), pearl millet (Pennisetum typhoides), sorghum (Sorghum vulgare Pers) and guandu (Cajanus indicus Spreng). The succession of each double cropping with the culture of corn constituted the treatments, in a total of six, which composed the portions, disposed in independent gleeful, while the depths in the soil of 7,5, 15,0, 22,5 and 30,0 cm constituted the sub-portions. A significant interaction was observed between successions of cultures and depths in the profile of the soils. Statistical differences were not observed. As far as depth to 30 cm is concerned, there was a significant reduction of the resistance to the penetration of soil, even more evident when sorghum and pearl millet were cultivated as double cropping cultures.
