A soya – the good predecessor of rice
Soya – the good predecessor of fig. According to experiences of all-union scientific research institute of rice, on the average in three years the crop of white grain after a soya was same, as well as after a lucerne. In a number of risoseyushchy regions of Odessa region a soya started to cultivate in rice checks.
In KSP "Frontier guard" of the Kiliysky area in separate checks the crop of a soya of Arcady the Odessa reached 35 c/hectares. Place it in those checks where level of ground waters isn’t higher than 40-50 cm from a surface of the soil and there is no flooding. In rice crop rotations it is necessary to cultivate Arcady’s early riper grades Odessa and Altair.
Because of strong distribution of cereal weeds (a prosyanka, klubnekamysh) their suppression on crops of a soya takes on special significance. The excellent effect here gives pivot which bring after emergence of shoots of a soya in mass emergence of weed plants. In JSC Mayak of the Kiliysky area during this period successfully apply new herbicide galaksi a top in a dose of 2,5 l/hectares.
As soils of rice checks differ low fertility, a nitraginizatsiya of seeds – an indispensable condition of receiving big crops. Productivity of a soya on rice checks when using nitragina increases on 5,0-8,4 c/hectares. Application of one fertilizers, even in high doses, was less effective, than an inokulyatsiya of seeds (productivity of 20-22 c/hectares). Phosphoric fertilizers should be brought in the autumn under plowing.
