Resumo: This work is a preliminary study on the development and yield of the peanut crop in an adaptation experiment at industrial scale, run in 17 plots in Ribatejo, using a variety type runner. The weeds were one of the most serious problems to solve, as a result of the absence of register pesticides in Portugal. The most important species were Amaranthus albus L., Amaranthus retroflexus L., Datura stramonium L. and Cyperus rotundus L. The most appropriate irrigation scheme involving intense irrigation (about 555 mm / cycle) every 2 days. The evaluation of the degree of maturity by the color of the pod exocarpo after scaling and the huge machines used to harvesting the crop are not suitable for our country without adaptation Crop yield ranged from 0.2 to 5 t / ha. A Principal Component Analysis showed that the planting date was the main yield determining factor (r = -0.62). The planting delay resulted that harvest occurred during the rainy season with losses of pods. Weeds also affect yield. The ideal planting date (yield> 3.5 t / ha, cycle of ≈ 150 days) was between April 29 and May 16. Future trials should be able to locate more precisely the sowing date in view of the normal rainfall in the region and will also be able to control weeds more effectively
