RESUMO: O experimento , instalado em um Latossolo Vermelho-Amarelo muito argiloso, teve o objetivo de obter melhor alternativa para o cultivo do algodoeiro herbáceo (Gossypium hirsutum L. r. latifolium Hutch) em plantio direto em condições de sequeiro no Cerrado. O delineamento experimental foi o de blocos casualizados com quinze tratamentos e quatro repetições. Os tratamentos foram os seguintes: soja-milheto-soja-milheto-algodoeiro (T1); soja-amaranto-soja-nabo-forrageiro-algodoeiro (T2); soja-sorgo granífero-soja-sorgo granífero-algodoeiro (T3); soja-aveia-preta-algodoeiro (T4); feijão-milheto-feijão-milheto-algodoeiro (T5); feijão-amaranto-feijão-nabo-forrageiro-algodoeiro (T6); feijão-sorgo-granífero-feijão-sorgo-granífero-algodoeiro (T7); feijão-aveia-preta-feijão-aveia-preta-feijão-algodoeiro (T8); milho-milheto-milho-milheto-algodoeiro (T9); milho-amaranto-milho-nabo-forrageiro-algodoeiro (T10); milho-sorgo-granífero-milho-sorgo-granífero-algodoeiro (T11); milho-aveia-preta-milho-aveia-preta-algodoeiro (T12); soja-soja-algodoeiro (T13); feijão-feijão-algodoeiro (T14) e milho-milho-algodoeiro (T15). O maior rendimento do algodoeiro foi obtido com a rotação soja-milheto-algodoeiro em que houve melhor controle de plantas daninhas; entretanto, o maior desempenho econômico ocorreu na rotação com feijão. ABSTRACT: The experiment carried out in a heavy red yellow latosol was aimed at obtaining alternative cultivation strategy to render higher soybean and herbaceous cotton yields in no-till system under rainfed Savannah conditions. The experimental designed used was a completely randomized with fifteen treatments: soybean-millet-soybean-millet-cotton (T1); soybean-amaranth-soybean-forage radish-cotton (T2); soybean-grain sorghum-soybean-grain-sorghum-cotton (T3); soybean-black rye-soybean-black rye-cotton (T4); bean-millet-bean-millet-cotton (T5); bean-amaranth-bean-forage radish-cotton (T6); bean-grain sorghum-bean-grain sorghum-cotton (T7); bean-black rye-bean-black rye-bean-cotton (T8); maize-millet-maize-millet-cotton (T9); maize-amaranth-maize-forage radish-cotton (T10); maize-grain sorghum-maize-grain sorghum-cotton (T11); maize-black rye-maize-black rye-cotton (T12); soybean-soybean-cotton (T13); bean-bean-cotton (T14); maize-maize-cotton (T15) and four replications. The highest cotton seed yield between treatments was obtained in the following sequence soybean-millet-soybean-millet-cotton where best weed control occurred too.

The design and management of drip irrigation systems requires understanding of water distribution and dynamics within the wetted soil volume. The information can be obtained by means of analytical or numerical solutions of the multidimensional Richards equation. Though steady-state sulutions have bean advocated as design tools for drip irrigation, very little information about their performance under practical field conditions is available. The objective of this study was to evaluate the applicability of analytical solutions for steady and transient flows from point sources to practical drip irrigation management. The emphasis was the adaptive and dynamic aspects of managemente vs. conservative disegn considerations. Experiments were carried out in containers and in the field to determine steady-state attainment rates and to provide information on spatial and temporal dynamics of water content and matric potential during irrigationcycles. The main results were:(i) analytical solutions for steady and transient flow conditions predicted reasonably well measured distributions of water content and matric potential in the absence of plants; (ii) steady flow conditions were seldom realized under practical drip irrigation; (iii) transient flow solutions provided a more realistic description of soil water dynamics; and (iv) introducing uptake termsinto transient analytical solutions provided a simple and effective framework for capturing soil water dynamics in the presence of plant roots.
