The aim of the present study was to determine the effect of compost, digestate and PGPB (plant growth-promoting bacteria) on yield forage accumulation curve, growth rate, forage height and SPAD (soil plant analysis development) units in newly established of cocksfood under greenhouse conditions. The treatments were digestate (60%); compost (10% on dry soil based); bacteria: Brevibacterium frigoritolerans, Bacillus simplex and Pseudomonas putida; positive control (triple 17 fertilization) and negative control (soil without fertilization). A completely random experimental design was used, the experimental unit was a pot with ten tillers, with four replicates by treatment. The highest values (p< 0.05) of dry matter yield (6.4 g DM pot), growth rate (0.15 g DM pot d-1) and forage height (18.3 cm) were recorded in treatment with compost, with which the final yield was 200% higher than the negative control. The treatment with digestate showed lower values than those obtained with compost but surpassed the rest of the treatments. The best PGPB were Pseudomonas putida and Bacillus simplex, which outperformed Brevibacterium frigoritolerans and negative control by 25 and 37%, respectively. The PGPB bacteria can be a fertilization alternative since the yield was higher than with the negative control and was equal to the yield with chemical fertilization; however, the two organic fertilizers (compost and digestate) favored the higher yield.
