Abstract

Crambe (Crambe abyssinica Hochst) is an alternative raw material for biodiesel production. It is highly resistant to drought and has short growing cycle of 90 to 100 days. This work was conducted in Umuarama city, Parana State, Brazil, in Haplortox typical and aimed to study the effect of row spacing and population densities in the development of crambe in two growing seasons. The experimental design was a randomized block in a 3x3 factorial scheme with four replications. The treatments consisted of three row spacing (15, 30 and 45 cm) and three population densities (500 thousand, 750 thousand and 1 million plants per hectare). It was evaluated the thousand grain weight, oil content and grain yield. It can be concluded that high and low spacing plant population lead to smaller yields.
