Assessment of the effect of optimised field plot size on the crop yield
Elbl, Jakub; Kintl, Antonín; Brtnický, Martin; Širůček, Petr; Mezera, Jiří; Smutný, Vladimír; Vopravil, Jan; Holátko, Jiří; Huňady, Igor; Lukas, Vojtěch (Česká akademie zemědělských věd, 2023)The presented research deals with the effect of plot size changes on the crop yield. Three plots were chosen in a company engaged in conventional agriculture, on which yields were monitored from 2019 using yield maps. In ... -
Comparison of Proximal and Remote Sensing for the Diagnosis of Crop Status in Site-Specific Crop Management
Mezera, Jiří; Lukas, Vojtěch; Horniaček, Igor; Smutný, Vladimír; Elbl, Jakub (MDPI AG (Multidisciplinary Digital Publishing Institute-MDPI), 2022)The presented paper deals with the issue of selecting a suitable system for monitoring the winter wheat crop in order to determine its condition as a basis for variable applications of nitrogen fertilizers. In a four-year ... -
Effect of Drought on the Development of Deschampsia caespitosa (L.) and Selected Soil Parameters during a Three-Year Lysimetric Experiment
Elbl, Jakub; Lukas, Vojtěch; Sobotková, Julie; Huňady, Igor; Kintl, Antonín (MDPI AG (Multidisciplinary Digital Publishing Institute-MDPI), 2023)This work presents results from a field experiment which was focused on the impact of the drought period on microbial activities in rhizosphere and non-rhizosphere soil. To demonstrate the effect of drought, the pot ... -
Monitoring Drought Tolerance Mechanisms of Sorghum and Maize Under Unevenly Distributed Precipitation
Frantová, Nicole; Rábek, Michal; Porčová, Lenka; Jovanović, Ivana; Širůček, Petr; Lukas, Vojtěch; Hájek, Josef; Elzner, Petr; Holková, Ludmila; Smutná, Pavlína; Smutný, Vladimír; Středa, Tomáš; Cerkal, Radim (Springer Switzerland, 2024)The study examines the morpho-physiological differences in leaf characteristics between two species of C4 plants: sorghum and maize. The research was conducted in field conditions where plants were rainfed. Both species ... -
