| Summary: | PURPOSE of the experiment was the impact of biofertilizers, such as boron and molybdenum humate on the chemical composition of grass biomass of bird's-foot trefoil, red clover and sainfoin.
METHODS: The treatment of bird's feet, red clover, sainfoin with boron and molybdenum humate was studied at a dose of 1600 ml/ha.
RESULTS: Boron humate had a positive impact on crude protein content in sainfoin. Molybdenum humate increased crude fats of bird's-foot-trefoil forage. Biofertilizers decreased crude fiber in sainfoin. Boron humate increased crude ash in red clover, while NFE had the highest values in bird's-foot-trefoil.
Boron humate led to an increase in calcium content in bird's-foot-trefoil and sainfoin star, and decreased it in red clover. The developed graphical regression models: between plant height and the share of legumes in the
grassland is y = 0.3232x + 17.709; crude protein and leaves y = 0. 1036x + 12.514; NFE and stems y = 0.1547x + 29.11; crude protein and calcium y = 2.9505x + 8.8375 allow the nutritional value of the feed to be predicted.
CONCLUSIONS: Biofertilizers, such as boron and molybdenum humate (160 ml/da) can be recommended for inclusion in the growing technology for bird's-foot-trefoil, red clover and sainfoins, in order to improve forage quality. |
