Abstract
Brown mustard has a prominent genetic potential for seed productivity, which can be fulfilled by optimising the elements of cultivation technology, namely the nutrition system, which makes research relevant. The purpose of this study was to determine the complex effect of the combination of different variants for pre-sowing mineral feeding and foliar feeding with water-soluble fertilisers on the formation of productivity elements and biological yield of brown mustard seeds. Field, laboratory (for accounting for structural elements of the crop), and statistical (for mathematical processing of materials) research methods were used in the study. The study was conducted in 2020, 2021, and 2023 on the basis of the farm “KYRYCHENKO M” located in the central part of Borivskyi district of Kharkiv region. The experiment compared five variants of pre-sowing mineral feeding and five variants of foliar feeding with various combinations of water-soluble fertilisers. The largest number of seeds on the plant and the largest mass were in the variants of the combination of pre-sowing application of N45P45K45 and carrying out two foliar feedings during microphases 21-23 and 50-53 with a mixture of carbamide and complex fertiliser Quantum technical – 627.3 pcs. and 1.97 g, respectively. However, these indicators did not significantly differ from the variant with a lower dose of presowing fertilisers – N45P30K30. Generally, according to the experiment, the highest biological yield of brown mustard seeds in an average of three years was in the variants of the combination of pre-sowing application of N45P45K45 and N45P30K30 with two foliar top dressings with different mixtures of fertilisers – 2.72-2.79 t/ha. Proceeding from this, the best variant in the experiment was the pre-sowing application of N45P30K30 in combination with two foliar feedings during microphases 21-23 and 50-53 with a mixture of carbamide and the complex watersoluble fertiliser under study in single doses of 10 kg/ha and 2.0 l/ha, respectively. It was established that the highest biological yield of mustard seeds in all years was on the variants of pre-sowing application – N45P45K45 and N45P30K30. There was no significant difference between these variants by year. The findings of this study can be used by agricultural enterprises to adjust the nutrition system (pre-sowing application of complex fertilisers and foliar feeding), which will ensure a more complete fulfilment of the genetic potential of brown mustard productivity
