Formation of productivity of any agricultural crop depends on many factors. First of all, the soil and climatic conditions of the crop growing area, varietal or hybrid composition, seed quality, sowing dates and plant density, and strict adherence to all methods of cultivation technology are important. Corn hybrids of different maturity groups differ in morphological and biological properties. Thus, obtaining the potential yield of an individual genotype is possible under favorable conditions for the growth and development of plants, including high-variety agricultural machinery and natural conditions. The maximum yield of high-quality corn grain is formed under the condition of the optimal ratio of all structural elements: weight of 1,000 grains, number of rows of grains in an ear, number of grains in a row, number of grains on one ear, length and diameter of an ear. If one structural element is insufficiently developed, the yield can be compensated by other components. Since individual elements of the structure are formed at different stages of organogenesis, different conditions are necessary for their successful development. The hybrids used in our research revealed peculiarities in the formation of elements of the crop structure, depending on the timing of sowing and stand density. The sizes of the cobs that formed on the corn plants varied little under the influence of sowing dates and plant stand density, but were characteristic of a certain biotype. Studies have shown that all factors of the experiment affect the growth, development of plants and the formation of elements of the structure of the corn grain crop. According to the results of the measurements, it was established that the best indicators of all structural elements were observed for sowing hybrids of different maturity groups in the optimal period - the third decade of April. The highest values of all indicators were observed in the Olkani hybrid, which is explained by the genotypic features of this hybrid.

Actuality. Today, landscape designers are required to introduce a new assortment of plants into culture, in particular annual ornamental crops. The purpose of the study is to investigate the manifestation and relationships of morphometric indicators and varietal characteristics of plants of the genus Tagetes L. Materials and methods. The research material was 10 varieties of marigolds: Orange Prince, Sugar and Spices, Moonlight, Hawaii, Red Brocade, Cupid Lemon, Bolero, Mandarin, Marietta and Manjestik. The following research methods were used: field – determination of morphometric indicators and varietal characteristics of plants and the duration of the flowering phase of marigolds; laboratory – determination of varietal characteristics of the plant, leaves and inflorescences; statistical – identification of relationships between the studied indicators. Research results. The longest period of “beginning-mass flowering” was established in the varieties Red Brocade and Marietta (over 30 days). Medium-sized varieties were distinguished: Orange Prince, Moonlight, Hawaii and Manjestik. The Manjestik variety was noted for the number of inflorescences on the plant (97 pcs.). A semi-spreading plant habit and moderate branching of the plant were revealed in most varieties. The Hawaii variety was distinguished for leaf size. The largest baskets were noted in the varieties Orange Prince, Moonlight, Hawaii, Sugar and Spices. The type of flowers in the inflorescence of marigolds was established: tubular-reed, tubular and reed. The Marietta and Manjestik varieties were distinguished for the presence of a two-color basket. A strong relationship was established between the indicators: diameter and length of the basket with a peduncle, the indicator of plant height at the beginning of flowering and during full flowering; correlations of medium strength between the indicators: length of the basket with a peduncle and length of the peduncle; length and width of the leaf; as well as the inverse relationship between the number of inflorescences on the plant and the length and diameter of the basket. Conclusions. The duration of the period “beginning-mass flowering” in varieties of marigolds of the genus Tagetes L. was established. Morphometric indicators of the plant in the flowering phase and the manifestation of varietal characteristics of the plant, leaf and inflorescences in varieties of marigolds were determined. Relationships between the studied indicators were noted.

Seed productivity of mustard varieties depending on sowing rate
(2025) Shakalii, S. M.; Bahan, A. V.; Шакалій, Світлана Миколаївна; Баган, Алла Василівна
Fluctuations in climatic resources, with a tendency to increase temperature, today require an expansion of the range of agricultural crops, including oilseeds. This is possible by introducing more drought-resistant crops into the crop rotation, which are able to easily adapt to different growing conditions. One of such crops is white mustard1/2/3.

In organic farming, the use of plant growth biostimulants in crop cultivation technologies, including chickpea, has become widespread. The purpose of this study: to investigate the manifestation of productivity elements and the yield of chickpea varieties depending on the treatment with an organic growth stimulator. The study employed the following methods: field – to determine the level of yield, laboratory – to investigate the elements of productivity of chickpea, and statistical – to assess the reliability of experimental studies. By treatment options, the complex application of the product during pre-sowing seed treatment and foliar feeding of plants during the growing season was distinguished. The effect of organic growth stimulant on the increase of productivity elements of chickpea in this variant of the experiment was noted by an average of 10.0%. The greatest effect of the preparation was found in the complex treatment of seeds and plants of common chickpea in terms of seed weight per plant (24.0%). They were identified by the influence of varietal properties on the productivity elements of common chickpea varieties Triumf and Pamiat. The Pamiat variety with the seed treatment + foliar dressing variant was the best in terms of chickpea yield, but the Triumf variety had the greatest effect of the growth stimulator on the yield increase. Close correlations were found between seed weight per plant and thousand-kernel weight, number of beans per plant and number of seeds per plant, and yield with plant productivity and thousand-kernel weight. The findings of the study are recommended to be used to adjust the elements of chickpea cultivation technology to increase productivity in production conditions.
