The aim of this study was to determine the effects of the associations pea-barley and pea-wheat in six ratios (0/100, 20/80, 40/60, 60/40, 80/20, 100/0) of hydroponics on the percentage of dry matter, organic matter and crude protein, height of the plant, and on the yield of green fodder, dry matter, organic matter and crude protein. A randomized factorial 2 x 6 (ratio x association) with 5 replicates per treatment was used. The percentage of dry matter and yield of green fodder were statistically similar in pea-barley and pea-wheat associations. The percentages of organic matter and crude protein were affected by the association and the level of legume/grass ratio. The average percentage of crude protein in both associations was 22.37%. The proportion of legume/grass did not affect plant height.

The aim of this study was to determine the degradability of the association of forages and crop residues commonly used to feed cattle in the Huancavelica Region. The forage associations were white clover-Italian ryegrass and red clover-dactylis, while the harvest residues were maize, oat straw, peas, beans and quinoa. For the determination of the degradability of dry matter (DM), crude protein (CP) and neutral detergent fibre (NDF), three rumen fistulated Brown Swiss cattle were used. Samples of forages and harvest residues were placed in nylon bags and incubated for 4, 8, 12, 24, 48, 72 and 96 hours. Time zero (t0) was used for the calculation of the soluble fraction. The DM, CP and NDF degradability were influenced by forages and crop residues (p<0.05). The greater potential degradability of the DM and CP, and effective degradability of the DM, CP and NDF give the white clover-Itali...

The aim of this study was to evaluate the variation of the chemical composition and the performance of the oats-vetch, wheat-vetch and barley-vetch associations in various proportions of sowing in the form of hydroponic crops. The study was carried out in the city of Huancavelica, Peru, at 3690 meters above sea level. In total, 90 trays of 704 cm2 were used, with a density of 2.5 kg of seed/m2. Associations of oats/vetch (O/V), barley/ vetch (B/V) and wheat/vetch (W/V) with six proportions of grass/legume were used: 100/0, 80/20, 60/40, 40/60, 20/80 and 0/100. The fresh biomass production (FBP) and the chemical composition of the percentage fractions of dry matter (DM%), organic matter (OM%), neutral detergent fibre (NDF%), ethereal extract (EE%), crude protein (CP%) and total minerals (TM%) were determined. A completely randomized experimental design was used, with a factorial arrangeme...
