Study of variability of indicators of suitability for mechanized harvesting of lentil (Lens Culinaris Medik) samples

Abstract

The article presents the data of the analysis of the study of the most important parameters of suitability for mechanized harvesting in collection samples of lentils brought from different landscape-geographic regions. It was revealed that under the conditions of 2024 in the Karaganda agricultural production site, the height of large- and small-seeded lentil plants was the same (28.9 and 29.5, respectively), but did not exceed the standard for most variety samples. The height of attachment of the lower bean differed in lentil subspecies by 2 cm (higher in large-seeded lentils). As a result of the correlation analysis of the relationship between biometric indicators and yield, as well as biometric indicators between themselves (height and HFP), a stable positive relationship was established for both subspecies. In terms of productivity, large-seeded lentils revealed samples with significantly higher productivity and equal to the standard (ILL 485, Sakura, PI 468898, PI 451764, PI 435960, Slavyanka), and among small-seeded lentils, the VIR sample, k-192, was identified as the closest to the standard variety Krapinka.
