Abstract
The research was carried out in 9 sites (5 in 1999-00 and 4 in 2000-01) of a inner area of Sicily different for soil type, slope, exposure and preceding crop.The following treatments were studied: (i) conventional tillage and sowing at conventional time (CT); (ii) no tillage and sowing at conventional time (NTc); and (iii) no tillage and early sowing (NTe).In 2000-01 the effects of three nitrogen fertilization treatments (single application at planting, P, and split dressing at two different rates, S and S+) were also evaluated.No tillage systems (NTc and NTe) significantly increased grain yield compared to CT treatment; no differences were observed between the two sowing dates.The productive benefits of no tillage were associated with a decrease of grain protein content that was heavier with early sowing.Regarding N fertilization treatments, S compared with P allowed a significant yield increase; no interaction with tillage technique was found.At the lowest fertilizer rate, split fertilization allowed a significant increase of grain protein content only in NTe.
