Economic questions of precision maize production on chernozem soil
293-296Views:224It is one of the main topical objective to establish the conditions of sustainable farming. The sustainable development in crop production also calls for the harmony of satisfying human needs and providing the protection of environmental and natural resources; therefore, the maximum consideratio of production site endowments, the common implementation of production needs and environmental protection aims, the minimum load on the environment and economicalness. Precision farmin encompasses the farming method which is adjusted to the given production site, the changing technology in a given plot, the integrated crop protection, cutting edge technologies, remote sensing, GIS, geostatistics, the change
of the mechanisation of crop production, and the application of information technology novelties in crop production. Modern technology increases efficiency and reduces costs. The efficiency of crop production increases by reducing losses and the farmer has access to a better decision support information technology system. In addition, we consider it necessary to examine the two currently most important economic issues: “is it worth it?” and “how much does it cost?”. During the analysis of agricultural technologies, we used the precision crop production experiment database of KITE Zrt. and the Institute for Land Utilisation, Regional Development and Technology of the Centre for Agricultural and Applied Economic Sciences of the University of Debrecen.
During our analytical work, we examined three technological alternatives on two soil types (chernozem and meadow). The first technology is the currently used autumn ploughing cultivation. We extended our analyses to the economic evaluation of satellite navigationassisted ploughing and strip till systems which prefer moisture saving. On chernozem soil, of the satellite-based technological alternatives, the autumn ploughing cultivation provided higher income than strip till. In years with average precipitation supply, we recommend the precision autumn ploughing technological alternative on chernozem soils in the future. On meadow soil, the strip till cultivation technology has more favourable economical results than the autumn ploughing. On soils with high plasticity – considering the high time and energy demand of cultivation and the short amoung of time available for cultivation – we recommend to use strip till technologies. -
Effects of cultivation practices and hybrid selection on endofusariosis and mycotoxin contamination in maize
69-78Views:386The aim of this study was to determine the levels of deoxynivalenol (DON) and fumonisin mycotoxins in tillage and no-till systems in 2020 and 2021. Additionally, we sought to establish the levels of internal Fusarium infection in different tillage systems. We examined four tillage systems for two years (conventional tillage (plowing), conservation tillage, reduced tillage, and strip-till). The results indicate that toxin levels varied between the two years, with fumonisin production dominant in 2021, while DON toxin production was dominant in 2020. Regarding internal Fusarium infection, the lowest levels were observed in the plowing system in 2020, whereas in 2021, the lowest levels were measured in the reduced tillage system. Like the low DON levels in 2020, the plowing-based tillage system resulted in the lowest fumonisin levels in 2021. Throughout our experiment, the toxin levels were below the permissible limits for unprocessed corn, with DON levels under 1750 μg kg-1 and combined fumonisin B1 and B2 levels under 4000 μg kg-1. However, in areas where toxin contamination is typically problematic, considering the beneficial impact of plowing on reducing toxin contamination might be advisable when planning tillage.
