THE QUALITY OF MIXTURES OF PERENNIAL GRASSES AND LEGUMES EXPLOITED IN HAY REGIME UNDER CENTRAL OF MOLDOVA CONDITIONS.

The study was conducted during 2017-2019, within ARDS Secuieni and aimed to analyse the influence of fertilization and species mixture on fodder quality, as well as the determination of fodder content in crude protein (CP), NDF (neutral detergent fiber), ADF (acid detergent fiber) and calculation of relative forage quality (RFQ). Experimental factors were represented by fertilization (factor A), with four graduations: a1-N0P0; a2-N40P40; a3-N80P40; a4-N80+40P40, and by the mixture of perennial grasses and perennial legumes (factor B), with five graduations: b1 - 20% perennial grasses + 80% legumes; b2 - 65% perennial grasses + 35% legumes; b3 - 70% perennial grasses + 30% legumes; b4 - 70% perennial grasses + 30% legumes; b5 - 80% perennial grasses + 20% legumes. The results showed that the lowest content in crude protein, of 15.24 g/100 g d. s. was achieved in the variant fertilized with N40P40 and the highest value of CP (15.94 g/100 g d. s.) was obtained in the non-fertilized variant (control). The applied fertilizers influenced the crude protein content of each of the studied mixtures, the differences obtained being statistically assured. [ABSTRACT FROM AUTHOR]
