Effect of Planting Density in Two Thistle Species Used for Vegetable Rennet Production in Marginal Mediterranean Areas

In Mediterranean cropping systems, it is important to utilize marginal lands for the cultivation of non-food crops. Spontaneous thistle genera such as Cynara cardunculus L. and Onopordum tauricum Willd. are native southern Europe. Previous research has focused on their spontaneous growth in environment or ability supply biofuel. The aim this study was identify effect two different planting densities flower differentiation, vegetable rennet production weed control O. C. rainfed unfertilized systems. results showed that plant density influenced most biomass parameters but no significant differences were observed Higher both species beneficial control. We recommend use suitable organic
