In this study, we investigated the influence of soil cultivation method on the productivity and quality of pasture grass fodder. We found that increasing the depth of cultivation from 8–10 cm to 20–22 cm (using surface tillage with disk implements) improved the productivity of all the grass species studied – <em>Phleum pratense</em>, <em>Lolium perenne</em>, <em>Festuca </em><em>orientalis</em>, <em>Dactylis glomerata</em>, <em>Bromus </em><em>inermis</em>, <em>Phalaris arundinacea</em>, <em>Festuca</em><em> </em><em>rubra </em>– by an average of 2%–3% at an LSD<sub>05</sub> of 0.30 t ha<sup>−1</sup>, over a period of 3 years. On average, the most important factor influencing the production of 1 ha of dry mass appeared to be the species of grass, accounting for 57% of the variation. The depth of soil tillage was also important, accounting for 43% of the variation. Of all the species studied, the highest productivity was exhibited by <em>Lolium perenne </em>(0.35 t ha<sup>−1</sup> of dry weight). Increasing the soil cultivation depth led to an increase in the content of crude protein and albumen (0.9%–1.1%). According to the analysis of organic matter content and digestibility of the fodder, across the different depths of soil cultivation, the early ripening species <em>Dactylis glomerata</em>, and the average ripening species <em>Festuca </em><em>orientalis</em>, <em>Lolium perenne</em>, and <em>Bromus </em><em>inermis</em>, performed best. Considering the different depths of soil cultivation, <em>Lolium perenne </em>[154 g; surface tillage (disking) 8–10 cm] and <em>Festuca</em><em> </em><em>orientalis </em>(152 g; ploughing 20–22 cm) provided the most fodder units with digestible protein.
The problem of post-harvest winter rapeseed crops usage influencing siderate and green fodder, oil radish impacting siderate and forage, root and post-harvest remains of winter wheat, and also cattle manure (40 t/ha) influencing the weed littering of maize and grain under conditions of grain-cultivated crop rotation has been revealed by PS of NUBiP of Ukraine - Agronomic research station. It has been proved that the cleanest crops of maize on the typical low-humus and light-loamy black soils remained in the variants where its predecessors were oil radish and winter rape on green fertilizer. Compared to control (root and post-harvest remains of winter wheat), weed amount decreased by 54 and 37% accordingly. Oil radish had a sufficient toxic effect on weeds as it was evidenced by their weight which in this variant decreased under shelf cultivation by 72% and under chisel cultivation - by 61%. Higher yield of maize for both chisel and shelf cultivation was forming in variants with oil radish for siderate and green fodder. The yield increase was 0.3-1.0 under shelf cultivation and 0.7-1.2 t/ha under chisel cultivation.
The results of studying the influence of different systems of agriculture and measures of basic tillage on the number of microorganisms and its phytotoxicity in the field of winter wheat are presented. It is proved that different systems of agriculture and measures of basic tillage do not equally affect the microbiological activity of the rhizosphere of winter wheat in the number and species composition of microorganisms. As a result, the variants created different conditions for the course of biochemical processes in the soil and the formation of crop yields. Moldboard-boardless tillage and the ecological system of agriculture proved to be more promising.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
