Abstract
The effect of inoculation with two strains of Rhizobium (ISO3 and ISO12) on seed of a sainfoin type ‘two cuts’ from Reznos (Soria) on forage yield and nutritive value was studied in Asturias during 2014-2015. Field experiments were conducted in spring sowing in 2014 in Candás (Asturias). Five treatments were set up: 1: inoculation with ISO3 strain; 2: inoculation with ISO12 strain; 3: un-inoculated control; 4: un-inoculated plus N-fertilization (50 kg N/ha) and 5: Trifolium pratense cv AltasWede. The largest annual production of dry matter were found in treatments with sainfoin (8989-13 484 kg DM/ha) compared to red clover (7444-8945 kg DM/ha), not having a clear effect of inoculation. Sainfoin treatments had lower crude protein content (14.6 to 19.2%) than red clover (22.5%) being the values of the protein in the inoculated treatments (16.8 to 19.2%) higher than the in the un-inoculated (14.6 to 16.4%), with no differences between the two strains used. An observation of two samples taken per plot at the end of 2014 and 2015 showed that all sainfoin treatment plants had Rhizobium nodules, but there were significant differences between treatments inoculated (greater number of nodules) and un-inoculated.
