Phosphorus nutrition of winter triticale depend of different types and doses of fertilizers
Abstract
Aim. To determine the economic removal of phosphorus and its balance in the soil under different types and doses of fertilizers. Methods. Laboratory, measuring, comparative, analysis, statistical. Results. For the Ajax variety, the control variants had zero values of the balance intensity, which indicates the absence of compensation for the removal of the element. The application of P60K60 provided the highest balance intensity at the level of 115 – 124 %, which confirms the feasibility of using phosphorus-potassium fertilizers. Variants with additional nitrogen had stable indicators within 93 – 107 %, while P60 + N120 was characterized by instability, in particular, a zero value in 2024. For the LP 154 line, the control also had zero values. The most effective was the application of P60K60, which provided 120 – 126 %. Variants with background fertilizer and nitrogen gave 90 – 105 %, while P60 + N 120 in 2024 again showed a zero result. The use of phosphorus-potassium fertilizers provided the highest intensity of the phosphorus balance, while the control variants and separate nitrogen application did not compensate for the removal of the element. Conclusions. Phosphorus nutrition of winter triticale significantly depends on the conditions of nitrogen nutrition. For the Ajax variety, the average removal of economic phosphorus removal in the control was 76.1 kg/ha, while with the application of P60 + N120 the indicator increased to 108.2 kg/ha, and the maximum values of 114.7 kg/ha were observed in the Background + N120 variant. The application of K60 + N 120 provided 93.0 kg/ha, the combined application of P60K60 gave 84.5 kg/ha, and the variants with distributed nitrogen application Background + N60 + N60 and Background + N60 S35 + N60 provided 102.9 and 105.5 kg/ha, respectively. When growing the winter triticale line LP 154, the economic phosphorus removal rate was at the level of the Ajax variety. The control variants were characterized by a significant negative balance, which indicates a phosphorus deficiency. The application of P60K60 provided positive values within 7.9 – 11.6 kg/ha, and it is also advisable to note the variants with retail nitrogen application, where the balance ranged from insignificant negative to positive indicators (-2.6 to 4.0 kg/ha). In the case of P60 + N120 application, a sharp decrease was observed in 2024.
