The article presents the question of the effect of the effectiveness of various elements of cultivation technologies on the competitiveness of Camelina sativa and the profitability of its cultivation on acidic, low-fertility sod-podzolic soils. Fertilizers are one of the fast-acting and effective factors in increasing the yield of Camelina sativa. It was established that introduction of mineral fertilizers had a significant impact on competitiveness of Camelina sativa seeds. Dependence of productivity elements and yielding capacity on crops has been determined. It was established that spring cruciferous crops had different seed productivity. According to the results of conducted research, it was found that the highest seed yielding capacity among spring cruciferous crops had spring Brassica napus L., but the oil content in Camelina sativa seeds was 46.53%, which is 4.08% more than in Brassica napus L. Therefore, oil outcome from the yield of Brassica napus L. and Camelina sativa was almost the same.
The results of research on the influence of growing technology and its individual elements on the growth, development and photosynthetic activity of corn plants hybrid Moreland F 1 under conditions of Western region of Ukraine are presented. The purpose of the research was to determine influence of cultivation technology elements on the formation and efficiency of assimilation apparatus of sweet corn plants. Research was conducted during 2019-2021 on sod-podzolic soil using field, calculation-weighting, and mathematical-statistical methods. Dynamics peculiarities of individual leaf surface area of the plant and agrocenosis of corn as a whole by the stages of crop development have been determined. Based on the results of statistical and correlation analyses, dependences between main indices of photosynthetic activity and corn yielding capacity, as well as those that change the most under influence of agrotechnology elements, were determined. Reaction of the crop on the change in intensity level of cultivation technology has been established, which is manifested through the functional response of individual photosynthetic plant system and the crop as a whole and is expressed in strengthening of their assimilation activity. Optimal limits of biometric indices of photosynthetic activity of sweet corn plants in crops when being reached, a productive grain yield is formed, have been presented.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
