| Abstract An unresolved question about the use of animal waste in agriculture is its effect on the physical and chemical attributes of soil, especially in commercial grain producing areas that have adopted direct seeding system (DSS). Aiming at contributing to the clarification of this question, we conducted a study in the mid-north region of the Mato Grosso state, Brazil, in a soybean and maize commercial area consolidated in DSS. Different doses of liquid swine manure (LSM) were applied and compared with NPK mineral fertilization. The aim of this study was to evaluate the physical and chemical quality of the soil and the productive potential of the soybean and maize crops under LSM doses and NPK fertilizer. Results indicated an increase in levels of K, P,... |

| El presente estudio se dividió en dos etapas, la primera se realizó en verano del 2008, bajo condiciones de temporal y tuvo como objetivo seleccionar dentro de cultivares de diferente hábito de crecimiento, aquellos con mayor producción de biomasa, rendimiento y calidad nutrimental, en dos ambientes Montecillo (clima semiárido, CS) y San Pablo Ixayoc (clima templado, CT). Los resultados encontrados indican que en CS los cultivares de hábito de crecimiento indeterminado (CHCI) presentaron la mayor producción de biomasa, rendimiento y calidad nutrimental del ejote (235 g m-2, 1.38 kg m-2, proteína 22 %, FDA 31 %, grasa 1.9 % y fósforo 0.080 %, respectivamente) y los valores más bajos (86 g m-2, 0.41 kg m-2, proteína 19.5 %, FDA 21.4 %, grasa 1.7 % y fósforo... |

| Transactions among agribusiness agents are not exclusively carried out on the market, being also governed by alternative types of institutional arrangements, some of which determined upon contractual agreement. In the fertilizers sector, the companies intensified the offer of input packages to farmers, more specifically to soybean producers, object of this article. In order to acquire the fertilizers, these producers may choose to use their own financial resources, to obtain resources through financing with third parties, or they may recur to the said packages, which include soybean and financial resources in addition to the fertilizers, referred by the soybean producers to as “exchange”, since they acquire fertilizer paying with soybean for future... |
