Productivity of white mustard in the forest-steppe zone Middle Volga region

The experimental work has been carried out in 2020-2021 under sufficient (HTI-1.30) and insufficient (HTI - 0.87) moisture conditions, respectively to the years of research, on the meadow-chernozem soil of the collection plot in the FSBEI HE Penza State Agrarian University. Lucia variety has been sown at the seeding rate from 1.5 to 3.0 million pcs/ha of germinating seeds with 0.5 million interval in rows and in skip-rows. An increase in the seeding rate from 1.5 to 3.0 million pcs/ha has not had a significant effect on the volume of seedlings, which, on average, has been 81.0...82.0% in row sowing and 72.0...73.0% in a thirty-centimeter-interrow sowing over the two years of research. The highest yield of mustard 1.93…2.04 t/ha was obtained at seeding rates of 2.0 and 2.5 million germinating seeds in row sowing. A decrease or increase in the sowing rate, as well as a change in row spacing up to 30 cm, results in a significant decrease in seed yield (up to 1.81 and 1.88 t/ha).
