Efficiency of application of agrochemicals when growing soybeans no-till technology in conditions of central black earth region of Russia
Bibliographic record
Abstract
Field experiments to study the effectiveness of the use of mineral fertilizers, a fungicidal seed disinfectant and an inoculant on soy were conducted in 2018-2020 on a typical heavy-loamy chernozem of the production farm "Levoberezhnoye" LLC "EkoNivaAgro", which is in the central part of the Voronezh region. The objects of research were soybean variety OAK Prudence (originator of the University of Guelph, Canada), inoculant Nitragin Zh (Fragaria, Argentina), fungicidal seed disinfectant Delit Pro, CS, pyraclostrobin 200 g/l (BASF, Germany). Mineral fertilizers were represented by ammonium nitrate (34.4%), ammophos (12:52) and diammophos (10:26:26). Soybeans were cultivated using the No-Till direct seeding technology. The sowing of soybeans was carried out with an Amity Single Disc Drill equipped with single-disc coulters with a row spacing of 38 cm. The forecrop of soy was corn for grain. The application of mineral fertilizers was carried out simultaneously with sowing in the row spacing. The yield of soybean grain in the control variant (without the use of agrochemicals) was the highest in the favorable moisture content of 2018, 1.50 t / ha, and almost the same in 2019 and 2020 – 1.24 and 1.23 t/ha, respectively. Average for 2018-2020 the yield of soybean grain in the control variant was 1.32 t / ha. The maximum grain yield was obtained on the variant with the combined use of the inoculant Nitragin Zh and ammonium nitrate at a dose of 200 kg / ha – 2.08 t / ha. The increase compared to the control variant was 0.76 t/ha or 57.0%. The greatest influence on the technological parameters of soybean seeds was exerted by pre-sowing inoculation of seeds and post-sowing application of nitrogen fertilizers at a dose of N70. Inoculation provided an increase in the protein content in soy seeds by 4.1%, and the application of N70 by 4.3% in absolute terms compared to the control.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
