Analýza herního výkonu ve vztahu k různým způsobům realizace utkání basketbalu minižáků / Analysis of the game performance in relation to different types of the match mini-basketball players.

Dvořáková, Pavla January 2015 (has links)
Title: Analysis of the game performance in relation to different types of the match mini-basketball players. Objectives: The objective of this study is analysis and comparison of the selected performance indicators of the player in relation to the current competiton system in the Czech minibasketball (5x5 vs 3x3 with one basket). Methods: As a research method, the method of observation of the video recordings. Using the basic statistic and arithmetic methods, the measured data were processed statistically and consequently, graphically also. Results: It was discovered that frequency of selected performance indicators is higher , for the whole team as well as individual players in form of modified minibasketball 3x3, in most cases. Key words: 5x5, 3x3, performance indicators, modification, U11, U12, Baskeťáci TJ Sokol Josefov

INVESTIGATION OF CORN YIELD IMPROVEMENT FOLLOWING CEREAL RYE USING STARTER NITROGEN FERTILIZER

Houston L Miller (7830965) 20 November 2019 (has links)
Cereal rye (CR), the most common and effective nitrogen (N) scavenging cover crop option in the Midwest, is often utilized in cropping systems to reduce nitrate loss for environmental benefits. To increase environmental efficiency in Midwest corn cropping systems, we must increase the overall adoption of CR. However, due to the yield reduction potential (6%) for corn planted after CR termination, CR is primarily recommended before soybean. To increase CR adoption, we must develop adaptive fertilizer management practices that achieve competitive grain yields relative to cropping systems where CR is not adopted. Therefore, the objectives of this study are to determine (1) the effect of CR and starter nitrogen rate on corn growth and nitrogen content. (2) the optimum starter nitrogen rate to achieve agronomic optimum corn yield following CR. (3) the impact of phosphorus (P) at starter on plant growth, nitrogen content, and yield with the inclusion of CR. For our study, five starter N rates were applied in a 5x5 cm band to both CR and non-CR plots, concentrations ranged from 0-84 kg N ha<sup>-1 </sup>in 28 kg N ha<sup>-1</sup> intervals. Total N applied was the same for each treatment, relative to its location, and was split between starter N at planting and sidedress applied at growth stage V6 relatively. Although CR termination took place at least two weeks before planting, CR decreased corn grain yield at one of three locations by an average of 8%, nitrogen recovery efficiency (NRE) by 27%, and R6 total N content by 23%, relative to the conventional control (non-CR 0N), when no starter N was applied. At one of three locations, starter N rates of 56 kg N ha<sup>-1</sup>, 56 kg N ha<sup>-1 </sup>plus 17 kg P ha<sup>-1</sup>, and 84 kg N ha<sup>-1</sup> increased corn grain yield, in CR plots, and 56 kg N ha<sup>-1</sup> plus 17 kg P ha<sup>-1</sup> increased corn grain yield in non-CR plots. Phosphorus increased corn grain N content at growth stage R6 in one of three locations and did not impact corn grain yield at all locations. We conclude that the inclusion of starter N at planting has the potential to increase agronomic productivity in CR corn cropping systems in soil environments with a high capacity to mineralize soil N. However, further research is required to refine our starter N results to find an optimum starter N rate to apply before planting corn following CR.
