摘要

This?research?was?aimed to assess the?influence of?density with different?row spacingon sunflower?crop in?two?different locations?in southern?Italy.?The experiment was laid out in a randomized block design with four replicates. It involved the comparison of sunflower grown in the field on 25 m2?(5 x 5 m) plots at three plant densities (7.5, 5.0 and 3.75 plants m-2), obtained by keeping a constant number of plants within the row (3 plants m-1) and varying the spacing between rows (0.4, 0.6 and 0.8 m).?In the cropsgrown?at the?density?of 7.5?plants?m-2?(0.4?m row spacing) achene and oil?yields were significantly?lower as compared to the other treatments.?Therefore,?the?mean valuesof the two trials?did not show?any?statistical difference?between the two densities?of 3.75?and?5 plants?m-2?(0.8?and?0.6?m row spacing,?respectively).?However,?thesuperiority?in the quality?of the?fatty acid composition?was observed in the crops grown at lower density.?Therefore,?the row spacing of?0.8 m?seems to be?a?good compromise?between achene production and good?acid composition?of oil.
