description The objective of this research was to evaluate the effect of different spacing plantings and intercropping models on physic nut trees yield in two harvest seasons. The experimental trial was carried out in Coronel Pacheco, Minas Gerais, in a randomized complete bocks design, in a split-plotted scheme. The experimental unit was represented by 5 different spacing plantings 6x3m (555 pl [ha.sup.-1]); 12x(2x2)m (714 pl [ha.sup.-1]); 10x(2x2)m (833 pl [ha.sup.-1]); 8x(2x2)m (1,000 pl [ha.sup.-1]); 6x1,5m (1.111 pl [ha.sup.-1]) and the subunit by two intercropping models (crop-livestock-forestry--iLPF, and livestock-forestry--SSP). The evaluation period contemplated 2010/2011 and 2011/2012 harvest seasons. The results showed that the higher spacing planting (6x3m) had a positive effect on individual tree yield, overcoming the others. No effect was observed for number of seeds per fruit and seed weight. The yield per hectare was higher in the closest spacing planting (6x1.5m), however it did not follow a linear trend. The iLPF system affected yield positively, overcoming the SSP system. Key words: agroforestry, biodiesel, Jatropha curcas. O objetivo deste trabalho foi avaliar o efeito de diferentes arranjos de plantio proprios para o consorcio com a atividade agricola e pecuaria, bem como tipos de consorcio na producao de plantas de pinhao manso em duas safras. O experimento foi realizado no municipio de Coronel Pacheco, Minas Gerais, em delineamento em blocos ao acaso, em esquema de parcelas subdivididas, sendo a parcela representada por 5 espacamentos: 6x3m (555pl [ha.sup.-1]); 12x(2x2)m (714pl [ha.sup.-1]); 10x(2x2) m (833 pl [ha.sup.-1]); 8x(2x2)m (1.000pl [ha.sup.-1]); 6x1,5m (1.111 pl [ha.sup.-1]) e a subparcela representada por dois tipos de consorcio (integracao lavoura-pecuaria-pinhao manso--iLPF, e integracao pecuaria pinhao manso--SSP). As avalicoes contemplaram as safras 2010/2011 e 2011/2012. Os resultados demonstraram que o maior espacamento de plantio (6x3m) apresentou efeito positivo na producao por planta, superando os demais tratamentos. Nao foram observados efeitos significativos no numero de sementes por fruto, bem como no peso da semente. A producao por hectare, foi maior no espacamento 6x1,5m (maior densidade populacional), entretanto nao seguiu uma tendencia linear. O sistema iLPF apresentou efeito significativo na producao, superando o sistema SSP. Palavras-chave: agrossilvicultura, biodiesel, Jatropha curcas L.
