The issue of herbicide influence on the basic sowing qualities of soybean seeds grown with their application is topical.
The aim and tasks of the study. Offering of soil and post-emergence herbicides permitted for use in soybean crops has grown in recent years. However, effects of these herbicides on the basic sowing qualities of soybean seeds grown with their application have not been studied. To establish productivity parameters, germination energy and laboratory germination capacity of soybean seeds grown with application of soil and post-emergence herbicides.
Material and methods. The experiment was laid out on typical black soil. Soil herbicides were applied before sprouting, and post-emergence ones - after soybean sprouting. The size of the registration plot was 36 m2; the experiment was repeated in three replicas. Soybean was harvested wit a harvester «Sampo-130." Sowing qualities of soybean seeds were evaluated by specialists from the Laboratory Seed Production and Seed Investigations of the Plant Production Institute nd. a V. Ya. Yuriev of NAAS of Ukraine.
Results and Discussion. Pre-emergence application of Harness herbicide and post-emergence application of tank mixtures from agents Nabob (1.0 L / ha) + Fabian (50 g / ha) + Miura (0.6 L / ha) and Nabob (1.5 L / ha) + Fusilade Forte 150 EC (0.8 L / ha) provided the highest soybean yields. Moisture regimen in some study years influenced the yield capacity and sowing qualities of soybean seeds. Soybean seeds grown with pre-emergence (100 g / ha) and post-emergence (70 g / ha) application of Fabian herbicide in tank mixture with graminicides Fusilade Forte 150 EC (0.6 L / ha), Panther (0.8 L / ha) and Miura (0.4 L / ha) had low germination energy. Soil and post-emergence herbicides did not significantly affect the laboratory germination capacity of soybean seeds.
Conclusions. Among soil herbicides, Harness agent provided the maximum soybean yield, and among post-emergence ones tank mixtures from agents Nabob + Fabian + Miura and Nabob + Fusilade Forte 150 EC stood out. Pre-emergence and post-emergence application of Fabian in tank mixture with graminicides reduced germination energy of soybean seeds. No significant effect of herbicides on the laboratory germination capacity of soybean seeds was found.
