The effectiveness of the methods of basic processing of gray forest soil in the link of crop rotation in the production of spring rapeseed and surepitsa seeds

Abstract

The article offers studies to determine the effectiveness of processing methods for the productivity of spring rapeseed and surepitsa on the dark gray forest soil of the Ryazan region. As a result, it was revealed that the maximum intensity of decomposition of flax tissue was recorded in the steam link of the crop rotation using the dump method of basic tillage for oilseed cabbage crops. The maximum yield of rapeseed was observed on the variant of the steam link of crop rotation + dump processing (31.3 c / ha), in the surepitsa (25.6 c/ha). A high increase in oilseeds in this variant is 4.7 c / ha, where the NSR05 factor with 0.97 c / ha relative to the minimum basic tillage was recorded in 2015. In the experiment, the trends of increasing the yield of oilseeds of spring rapeseed and surepitsa in the fallow link of the crop rotation relative to the row crop are revealed. The maximum oil content of rapeseed was noted in the rowed link of crop rotation during milling tillage (47.6%); in surepitsa – in the rowed link of crop rotation also during milling (45.1%).

“…В среднем максимальная урожайность у рапса отмечалась на варианте парового звена севооборота + отвальная обработка -31,3 ц/га, у сурепицы -25,6 ц/га. Фрезерование во все годы опытов дало средние показатели продуктивности яровых масличных культур по фактору С: от 20,5 ц/га (2019 год) до 29,0 ц/га (2020 год).Отметим, что в среднем по годам опытов[26] масличность ярового рапса сорта Ратник варьировала в пределах 43,4-47,6 %, яровой сурепицы сорта Липчанка -42,0-45,1 %, и существенных зависимостей от вариантов звена севооборота и интенсивности обработки не обнаружено (рис. 2).…”
