Confronto fra cultivar di soia: un biennio di sperimentazione in Sardegna

During the years 1981 and 1982 a comparison trial among different late planted soybean cultivars has
been carried out in the experimental field of «S. Lucia» (OR).
Two sowings took place: the first one within the end of May and the second one in the end of June.
Fourteen cultivars belonging to the I, II, III and IV ripeness groups have been used in the first sowing,
whereas in the second sowing the cultivars were eleven and they belonged to the I, II and III groups.
Variable grain yields (tram 30 up to 41 q/ha) have been provided by the I, II and III maturation groups in
both sowings.
A drying process of grain could be avoided because of the low humidity at the harvesting of the varieties
belonging to the I and II groups.
The achievements show the real possibility to insert soybean instead of summer sowing cultivation of
maize because of maize sensitivity to insects.
