AB  - Weed seed banks are an inexhaustible and permanent source of weeds, but they also have a stabilizing effect on the ecosystem and biodiversity in plant production systems. Scarce rese-arch on this topic has shown great variability in results, in part, due to different methodology of the seedbank estimation. The aim of this research was to compare two methods of estimating weed seed bank: 1) physical extraction of seeds, and 2) seedling emergence method. The plo¬ts of the stationary experiment "Plodoredi", Institute of Field and Vegetable Crops, Novi Sad, Serbia (N 45° 19', E 19° 50') were used for these research. Soil samples were taken from two experiments, a 50-year winter wheat monoculture, and from a three-year crop rotation (winter wheat-maize-soybean), over the course of three years (2014-2017). The method of physical extraction, although longer and physically more exhaustive, showed better results. In winter wheat monoculture 12 weed species were recorded, with a total of 21575 seeds m-2, while in the three-year crop rotation 25 weed species were detected, with a total of 16300 seeds m-2. Using the seedling emergence method only five weed species and 8500 seeds m-2 were estimated in monoculture, while in crop rotation five weed species and 4500 seed m-2 were estimated. This indicates that the entire weed seed bank is not active: some seeds are not able to germinate, while others are dormant, but present a potential danger. The estimated number of seeds per m-2 by the more efficient method of physical extraction was used to create the “Artificial Neural Network’’ model which had been previously tested using the Random-Holback method. The model answered the key question: how monoculture and crop rotations can change the soil weed-seed bank and diversity in a long-term cropping system.

AB  - Crop rotation is known as an eco-friendlier approach, as provides diversification in crop management systems, modifies intensive pressure on the agricultural ecosystem, utilizes various soil horizons, and prevents the establishment of specific pests and weeds. We set out here a study on the farms that have been managed over 50 years of specific continuous crop management programs. The experimental treatments were in a different management system: monoculture of maize, winter wheat, and soybean, 2-year crop rotation (winter wheat–maize) with and without chemical fertilizer, and 3-year crop rotation (winter wheat–soybean–maize) with and without chemical fertilizer and manure. We took soil samples six times from 2014 to 2017 prior to sowing and after harvesting each year. Weed seeds were extracted from soils and identified and counted by species. We, upon the data of a long term experiment of crop rotation, could conclude that crop rotations with more crops in the sequence are significantly effective in maintaining weed populations, a low-input crop production could reach a constant low population below an important damaging density, and therefore will be a more sustainable crop production while chemical fertilizers would change the soil’s chemical and structure and imbalance the plant population diversity and manures with high weed seed infestations have the potential to totally eradicate crop rotation effects, Therefore, clean manures or compost are highly recommended.

AB  - Long-term monoculture has a de-stroying impact on plant production, while crop rotation is known as a more eco-friendly approach as provides diversification in crop management systems, modifies intensive pressure on the agricultural ecosystem, utilizes various soil horizons, and prevents the establishment of specific pests and weeds. The aim of his research was to answer: How management system over 50 years of specific continuous crop management programs (crop rotation and fertilization) effect on weed populations? This study was conducted in the experimental site of the Institute of Field and Vegetable Crops of “Plodoredi”, Rimski Šančevi, Novi Sad, Serbia. It has been estimated three monocultures of maize, wheat and soybean, 2-year crop rotation (winter wheat-maize) with and without chemical fertilizer and 3–year crop rotation (winter wheat-soybean-maize) with and without chemical fertilizer and manure. Soil samples were taken six times from 2014 to 2017 prior to sowing and after harvesting each year. Weed seeds were extracted from soils and identified and counted by species. Mixed model analysis was used to determine the effect of the crop sequence and fertilizers on weed seed bank. To compare the strength of the treatment, it calculated the log-worth with their P-values. Upon the data of a long term experiment of crop rotation, could approve that crop rotations with more crops in the sequence are significantly effective in maintaining weed population. Therefore, will be a more sustainable crop production, chemical fertilizers would imbalance the plant population diversity and manures with high number of weed seeds have potentials to totally vanish crop rotation effects. Mixed model analysis suggests that on over 50 years of the management practices crop sequence × fertilizer interaction had the highest effect (log-worth = 64.7), followed by the triple interactions between crop sequence × fertilizer × soil depth (log-worth = 30.5). The number of seeds in soil significantly decreased from surface layer to deep soil. The crop sequence efficiency in decreasing weed seed bank was highly dependent on the fertilizer management, as with chemical fertilizer, the three years crop rotations had significantly lower seed bank, while with manure, the effect of crop rotations was eliminated.
