Background: Numerous experiments in Russia and abroad indicate that the productivity of natural hayfields and pastures is high enough only if legumes are present in the herbage. It is also of great importance to increase their productivity by applying mineral fertilizers, which often define the final productivity of the herbage. To determine the effect of organic and mineral fertilizers on the productivity of sainfoin. Methods: The main method used in the study was a field experiment combined with laboratory analysis. Measurements of plant density were carried out in the spring before each harvesting of cover crops and sainfoin. In the course of the study, phenological and morphological observations, accounting, and evaluation of the quality of sainfoin were carried out. The structure of the herbage was evaluated according to the following indicators: plant density, plant height, leafiness, and the area of the assimilation surface of grasses. Measurements were carried out in spring before each harvesting of grasses. Height measurements were based on the phases of plant development. Results: Final yield data show that fertilizers have a significant impact. Thus, the yield of sainfoin and cover crops in 2019 (in the first year of the experiment) was: 4.7 t/ha for variant 8 and 4.5 t/ha for the control variant. In 2020 and 2021, the yield of experimental variant 8 exceeded that of the control variant. Statistical processing of the results of the experiment confirms the positive effect of fertilizers on the yield. Conclusions: The best results were achieved with the use of 30 t/ha of organic fertilizers + N60 P60 K40. [ABSTRACT FROM AUTHOR] |
