Within the frame of an experimental project on organic farming, cultivation trials were performed to characterize rice varietal response on farms with expertise in rice organic farming cultivation. Selected varieties included recently developed and traditional ones belonging to all different merceological classes. For the round rice group, varieties chosen were Brio, Cerere and Selenio. For the long A group, varieties were chosen considering the different utilization: Loto and Opale, utilized for the production of parboiled rice while Ulisse and Volano for the national market. For the long B group were finally tested Arsenal, Ellebi and Salvo. The experimentation revealed an average yield of about 6 t/ha, therefore lower than those recorded under conventional farming conditions. The highest yield was observed in Costanzana (VC), where the average yield was above 6 t/ha with Brio, Opale and Volano being the best performing varieties with more than 7 t/ha, while in Mede (PV) average yield was lower (5,9 t/ha) and the varieties with highest yield were Brio, Volano and Salvo. Considering also the availability of data derived from the experimentation of the previous year, data highlighted that within the round group the variety Brio is the most adaptable to organic farming conditions. Within the long A group, Opale for parboiled rice, and Volano for national market demonstrated to provide good yield levels for both years, while within the long B group, Ellebi was the best performing considering the two years of trials.
