Cultivation of sudanese grass on sod-podzolic sandy soils under conditions of radioactive contamination
Abstract and keywords
Abstract (English):
The results of three years of field research on the effect of potash fertilizers on the yield of green and haylage and the quality indicators of Sudanese grass are presented. The yield of green mass of Sudanese grass in the experiment was 10.3–12.2 t/ha, grain haylage — 9.4–11.0 t/ha, depending on the dose of potassium fertilizers. The maximum yield of green mass and grain haylage of Sudanese grass was noted in the variant with the addition of K240. The highest collection of crude protein (214.1 kg/ha), feed units (1.37 thousand) and metabolizable energy (21.3 GJ/ha) and the content of metabolizable energy per 1 kg of feed (8.0 MJ) were noted in the variant with the addition of potassium at a dose of 240 kg/ha. The content of crude protein in green mass increased with increasing potassium dose. The highest content of 137Cs (224 Bq/kg) was observed in the control variant. Potassium fertilizers reduced the entry of radionuclide into the crop. In general, according to the experiment, the content of 137Cs in the feed did not exceed the permissible level (400 Bq/kg).
