- Abstract
This essay compared development and fruit production of Jatropha curcas L. in relation to growing space and presence of an herbaceous competitor. The essay was composed by two circular plots with four plant growing areas (1.57 m², 3.92 m², 6.28 m², and 8.63 m²) with eight replications for plot intercropped or not with Tifton 85. The cultivation of physic nut in the spacing of 6.28 m²resulted in lower plant height and higher levels of leaf nitrogen and phosphorus, while the 1,57 m²spacing resulted in increased plant height. The lowest values for plant height, number of leaves, number of fruits, SPAD index, and levels of nitrogen and phosphorus resulted in the intercropped plot. However, the 1.57 m²spacing yelded higher stem diameter. Crown diameter presented the highest values in the 3.92 m²spacing while the 1.57m² limited the crown expansion. Maximum fruit production in monocrop plot was reached 18 months after planting date, which corresponded to the warmest season independently of planting space.
