The aim of this research was to develop suitable machines for no-till sowing of sunflower and to evaluate the efficacy of different cultural practices in different sowing systems. During two-year trials a conventional sunflower sowing system, based on ploughing followed by some secondary soil tillage practices, was compared with a no-till sowing technique performed with a precision no-till planter developed and set up by the MAMA Division of DAGA at the University of Pisa. The efficacy of hoeing in combination with the two sowing systems was also evaluated. The no-till sowing technique performed with the no-till planter allowed a substantial saving on working times and fuel consumption as compared to the conventional system. In the first trial year productions were low in both systems and differences among treatments were not obtained, due to unfavorable climatic conditions that compromised crop development. But in the second trial year, productions were decidedly higher, the best results being achieved by adopting the no-till technique combined with hoeing. Use of the no-till planter allowed a substantial reduction in energy input and the no-till technique combined with hoeing gave the best energy productivity.

Abstract
The aim of this research was to develop suitable machines for no-till sowing of sunflower and to evaluate the efficacy of different cultural practices in different sowing systems. During two-year trials a conventional sunflower sowing system, based on ploughing followed by some secondary soil tillage practices, was compared with a no-till sowing technique performed with a precision no-till planter developed and set up by the MAMA Division of DAGA at the University of Pisa. The efficacy of hoeing in combination with the two sowing systems was also evaluated. The no-till sowing technique performed with the no-till planter allowed a substantial saving on working times and fuel consumption as compared to the conventional system. In the first trial year productions were low in both systems and differences among treatments were not obtained, due to unfavorable climatic conditions that compromised crop development. But in the second trial year, productions were decidedly higher, the best results being achieved by adopting the no-till technique combined with hoeing. Use of the no-till planter allowed a substantial reduction in energy input and the no-till technique combined with hoeing gave the best energy productivity.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
