2. METHODOLOGY FOR DIMENSIONING OF A CENTER PIVOT IRRIGATION SYSTEM OPERATING WITH DRIPPER TYPE EMITTER
ABSTRACT: In Brazil, the conventional center pivot is widely used for irrigation of agricultural crops and its use has grown continuously. However, when improperly managed, it facilitates the development of diseases in all parts of the plant, with a direct effect on productivity, besides favoring losses of water by evaporation. The drip may be an alternative

4. Método do tanque Classe A para irrigação da soja, cultivar Sambaíba, no Cerrado.
ABSTRACT: Efficient use of water resources is the key to guarantee suply for future human consumption and irrigation. In the irrigated areas of the Cerrado region pressurized irrigation systems allow high efficiency in water conduction. However, lack of knowledge in crop water requirement determine inadequated crop water management. Negative effect on crop d

6. Energy economy in a center pivot irrigation system according to the improvement in the uniformity of water distribution / Economia de energia em irrigação por pivô central em função da melhoria na uniformidade da distribuição de água
In irrigation systems by center pivot, the efficiency of applying in field is directly related to distribution uniformity, influencing in energy saving inside an appropriate irrigation management program. Were used data from applied layer, average layer, flow, and central pivot length, from Guairá SP, determined by IDE (1989) by a performance assessment. By

8. Modelo computacional para determinação do risco econômico em culturas irrigadas / Computational model for economical risk determination in irrigated cultures
The agricultural companies were submitted to risky conditions, so the utility of deterministic models to planning is relatively limited. That implies in not despise the randomness of some coefficients and to introduce them in the project analysis. As a proposal of this work a Computational model for risk determination in irrigated cultures was elaborated for
