Soybean (Glycine max (L.) Merr.) is the most important protein crop globally, with its cultivation area in Europe on the increase. To investigate how alternative tillage systems affect soybean growth, yield performance, and nitrogen fixation capacity in the early conversion period from conventional tillage to conservation and no-tillage practices, a field study was conducted in 2020 under the humid central European climatic conditions of Slovenia. A complete randomized block design with four repetitions was used for the three different tillage systems (conventional, conservation, and no-tillage). The results show that the majority of the studied soybean growth parameters (e.g., plant density, nodes per plant, and shoot and root dry matter) and the yield components (e.g., pods per plant, and 100-seed mass) were greatest for the reference conventional tillage system. The conventional system also showed significantly greater dry nodule mass (p < 0.01) and proportion of large-sized nodules (>4 mm) on both the tap root (p < 0.05) and the lateral roots (p < 0.001). A positive linear correlation between nitrogen content and nodule production in the roots also suggested increased nitrogen fixation for the conventional system. The less intensive conservation and no-tillage systems resulted in significantly greater soil compaction, which negatively affected early plant establishment and resulted in significantly decreased plant densities. Despite the large differences in plant stands and individual plant performances, no significant differences were seen for dry seed yields between these tillage systems. Dry seed yields for the conventional and conservation systems were 4.54 and 4.48 t ha−1, respectively, with only minor (non-significant) yield reduction for the no-tillage system, at 4.0 t ha−1. These data show that soybean cultivation in the early transition period to less intensive tillage systems have no major yield losses under these less suitable agro-climatic conditions if correct crop and weed management measures are implemented.

The objective of this work was to evaluate changes in the photosynthetic photon flux density (PPFD) interception efficiency and PPFD extinction coefficient for maize crop subjected to different soil tillage systems and water availability levels. Crops were subjected to no-tillage and conventional tillage systems combined with full irrigation and non-irrigation treatments. Continuous measurements of transmitted PPFD on the soil surface and incoming PPFD over the canopy were taken throughout the crop cycle. Leaf area index and soil water potential were also measured during the whole period. Considering a mean value over the maize cycle, intercepted PPFD was higher in the conventional tillage than in the no-tillage system. During the initial stages of plants, intercepted PPFD in the conventional tillage was double the PPFD interception in the no-tillage treatment. However, those differences were reduced up to the maximum leaf area index, close to tasseling stage. The lowest interception of PPFD occurred in the conventional tillage during the reproductive period, as leaf senescence progressed. Over the entire crop cycle, the interception of PPFD by the non-irrigated plants was about 20% lower than by the irrigated plants. The no-tillage system reduced the extinction coefficient for PPFD, which may have allowed a higher penetration of solar radiation into the canopy

In a semiarid Mediterranean site in central Spain, field experiments were conducted on a Calcic Haploxeralf (noncalcic brown soil), which had been managed with three crop rotations and two tillage systems (no-tillage and conventional tillage) since 1987. The crop rotations consisted of barley→vetch, barley→sunflower, and a barley monoculture. The study took place in two growing seasons (1992–1994) to assess the effects of management practices on the weed seedbank. During this period, spring weed control was not carried out in winter crops. In the no-tillage system, there was a significant increase in the number of seeds of different weed species: anacyclus, common purslane, corn poppy, knotted hedge-parsley, mouse-ear cress, spring whitlowgrass, tumble pigweed, venus-comb, andVeronica triphyllos.Conversely, the presence of prostrate knotweed and wild radish was highest in plots under conventional tillage. These results suggest large differences in the weed seedbank as a consequence of different soil conditions among tillage systems, but also the necessity of spring weed control when a no-tillage system is used. With regard to crop rotations, the number of seeds of knotted hedge-parsley, mouse-ear cress, and spring whitlowgrass was greater in the plots under the barley→vetch rotation. Common lambsquarters dominated in the plots under the barley→sunflower rotation, whereas venus-comb was the most frequent weed in the barley monoculture. Larger and more diverse weed populations developed in the barley→vetch rotation rather than in the barley→sunflower rotation or the barley monoculture.

Tillage System

Sugarbeets (Beta vulgaris L.) are grown on intensively tilled-irrigated land in southern Alberta, which is subject to soil erosion by wind. Experiments were conducted on commercial fields near Burdett, AB, to determine the effect of the tillage system and previous crops on sugarbeet production. The previous crops were dry bean (Phaseolus vulgaris L.) or wheat (Triticum aestivium L.) and the tillage systems were conventional (moldboard plow, vibrashank cultivator, harrow, packer), minimum (double disc, self-cleaning harrow, glyphosate) or no tillage (glyphosate). After dry beans, sugarbeet fresh weight and extractable sugar yields were similar with all tillage systems. All of the tillage systems left less than 100 g m-2 of plant residue on the soil surface in the spring following dry beans, which is insufficient to protect the soil from wind erosion. After wheat, sugarbeet yields were similar with minimum and conventional tillage but lower with no tillage. Both minimum and no-tillage systems left sufficient plant residue on the soil surface to protect the soil from erosion (> 200 g m-2). Sugarbeet stand density following wheat was lower with no tillage than conventional or minimum tillage, reflecting poor seed placement and daily maximum soil temperature (5 cm depth) of up to 10°C lower under no tillage than conventional tillage. After wheat, there was a trend toward lower densities of hard-seeded annuals, such as redroot pigweed (Amaranthus retroflexus L.), after no tillage than conventional tillage. Of the cropping systems tested in this study, only the minimum tillage system after wheat provided optimum sugarbeet yield and left enough plant residue to protect the soil from wind erosion. Key words: Crop rotation, bean, wheat, sugarbeet, no-tillage

A field study was carried out to determine the effects of tillage systems on sunflower yield over 9 years, and the effects of tillage systems and residual N on sunflower yield and yield components over 4 years, in a wheat–sunflower rotation under rainfed Mediterranean conditions. Tillage treatments included no tillage (NT) and conventional tillage (CT). Nitrogen fertiliser rates were 0, 50, 100, and 150 kg N/ha, applied only to wheat. A split-plot design with 4 replications was used. The weather had a marked influence on sunflower biomass and seed yield. Rainfall over October–May was directly related to seed yield. In contrast, seed oil content was inversely related to mean temperature during the flowering season (June). Sunflower yield displayed no significant reponse to residual N derived from the fertiliser N applied to the preceding wheat crop. The tillage system did not exert a consistent influence on sunflower yield; thus, continuous no-tillage may represent an economically and environmentally viable alternative to conventional tillage for sunflower production under rainfed Mediterranean conditions.

O experimento, conduzido entre 01/10/2019 a 10/02/2020, foi estabelecido em faixas, com parcelas subdivididas, quatro repetições e dois tratamentos (sistemas de cultivo e lâminas de irrigação). Nas parcelas, os sistemas de cultivo foram: semeadura convencional e semeadura direta. Nas subparcelas, as lâminas de irrigação (percentual da lâmina líquida - %IL) foram: 0, 30, 63, 100 e 193%. Após a colheita, a produtividade de espigas (com e sem palha) e de grãos na umidade de 20,5 e 13% foram avaliadas. Os resultados mostraram que: 1) o sistema de cultivo não influenciou na produtividade; 2) a produtividade respondeu de forma quadrática às lâminas de irrigação; 3) lâminas próximas a 100% da IL resultaram em produtividades máximas e; 4) a sensibilidade ao déficit hídrico promoveu decréscimos de 20,4% na produtividade. Quando o custo do milímetro de água for 10 vezes maior que o custo do quilograma do milho (umidade 13%), economicamente é mais viável produzir 7.957 kg ha-1 com 60% da IL do que alcançar a produtividade máxima (8.283 kg ha-1).   Palavras-chave: lâminas de irrigação, sistemas de cultivo, déficit hídrico.     Prado, G; Tinos, A.

Irrigated corn yield at the Arenito Caiuá region in Northwest of Paraná State, Brazil     2 ABSTRACT   This work was performed at Universidade Estadual de Maringá, in Cidade Gaúcha/PR city, Brazil, and aimed to evaluate the corn variety IPR-164 yield, in different tillage systems and irrigation depths. The experiment, carried out from 10/01/2019 to 10/02/2020, was set in strips design, with subdivided plots, four replications, and two treatments (tillage systems and irrigation depths). In the plots, the tillage systems were: conventional-tillage and no-tillage. In the subplots, the irrigation depths (percentage of the net irrigation depth - %NID), were: 0, 30, 63, 100, and 193%. After harvesting, the data corn ear yield (in-husk and unhusked) and the grain yield with the moisture of 20.5 and 13% were evaluated. The results showed that: 1) the tillage system did not influence the corn yield; 2) corn yield presented a quadratic response to the irrigation depths; 3) irrigation depths close to 100% of NID provided maximum yield; 4) the sensitivity to water deficit led to a 20.4% decrease in corn yield. When the millimeter water cost is 10 times greater than the corn kilogram cost (moisture 13%), it is economically more profitable to produce 7,957 kg ha-1 with 60% of NID than to reach  the maximum yield (8,283 kg ha-1).   Keywords: irrigation depths, tillage systems, water deficit.

A field study was conducted in 2014 and 2015 in Arkansas, Illinois, Indiana, Ohio, Tennessee, Wisconsin, and Missouri to determine the effects of tillage system and herbicide program on season-long emergence ofAmaranthusspecies in glufosinate-resistant soybean. The tillage systems evaluated were deep tillage (fall moldboard plow followed by (fb) one pass with a field cultivator in the spring), conventional tillage (fall chisel plow fb one pass with a field cultivator in the spring), minimum tillage (one pass of a vertical tillage tool in the spring), and no-tillage (PRE application of paraquat). Each tillage system also received one of two herbicide programs; PRE application of flumioxazin (0.09 kg ai ha–1) fb a POST application of glufosinate (0.59 kg ai ha−1) plusS-metolachlor (1.39 kg ai ha–1), or POST-only applications of glufosinate (0.59 kg ha−1). The deep tillage system resulted in a 62, 67, and 73% reduction inAmaranthusemergence when compared to the conventional, minimum, and no-tillage systems, respectively. The residual herbicide program also resulted in an 87% reduction inAmaranthusspecies emergence compared to the POST-only program. The deep tillage system, combined with the residual program, resulted in a 97% reduction inAmaranthusspecies emergence when compared to the minimum tillage system combined with the POST-only program, which had the highestAmaranthusemergence. Soil cores taken prior to planting and herbicide application revealed that only 28% of theAmaranthusseed in the deep tillage system was placed within the top 5-cm of the soil profile compared to 79, 81, and 77% in the conventional, minimum, and no-tillage systems. Overall, the use of deep tillage with a residual herbicide program provided the greatest reduction inAmaranthusspecies emergence, thus providing a useful tool in managing herbicide-resistantAmaranthusspecies where appropriate.

Roots may respond to restrictive soil physical conditions and send signals to shoots to control plant growth. Soil mechanical resistance and aeration can be managed to improve the soil physical conditions for plant growth by using different tillage systems. The objective of this study was to quantify the influence of no-tillage and conventional-tillage systems on plant response to soil mechanical resistance and aeration. The study was carried out on a farm, cultivated with corn, with a side-by-side comparison of no-tillage and conventional-tillage systems. Thirty-two paired sampling sites were located along two transects, located one in each treatment. Soil water content, bulk density, and plant growth were measured in each treatment. Based on the soil water and bulk density measurements, the air-filled porosity values were computed for each treatment. Soil water contents and bulk density values were converted to soil mechanical resistance by using the soil resistance curve. Plant growth varied positively with soil air-filled porosity, and negatively with soil mechanical resistance in both tillage systems. However, the decrease rates/increase rates were dependent on the tillage system. The no-tillage system somehow improved the soil physical conditions for the plants, especially when they were more restrictive, allowing them to attain greater values of growth.

Eight different tillage systems were compared in soybean production on one experimental field (chernozem) located in the Baranya region of Croatia over a 4-year period (2001/2002, 2002/2003, 2003/2004, 2004/2005). The dry conditions experienced in 2003 exacerbated the effects of NT and CWNS on the soybean yield. The most stable grain yield was obtained using CSNW and CSDW in all four experimental years. DH, CH and CWDS did not result in any significant reduction in crop yield compared to CT. There was no clear trend regarding the applied tillage systems and grain yield components. The greatest effects on soybean yield and yield components were due to climatic conditions. Different tillage systems had a significant effect on the soybean grain yield and yield components in the four experimental years. The largest differences in stem height were determined between CSNW and NT. The number of pods per plant, the hectolitre mass and the grain yield were significantly lower under NT than under the other tillage systems. The number of fertile nodes of soybean and the number of branches per plant in the experimental years had approximately the same values for all the tillage systems. To sum up, the results achieved with DH, CH, CSDW, CWDS and CSNW were on par with each other and slightly better than CT, and these systems could represent adequate replacements for conventional tillage. No tillage could not be considered as the most favourable for soybean growing.

Postemergence and commonly used preemergence plus postemergence herbicide programs were evaluated for weed control in conventional and no-tillage soybeans double cropped after winter wheat in the northern Mississippi River Delta. Broadleaf weed species present varied with tillage, location, and year. Large crabgrass was present in both tillage systems for all locations and years. Conventional tillage usually resulted in higher densities of large crabgrass, common cocklebur, and smooth pigweed. Soil-applied preemergence herbicides alone did not provide season-long ivyleaf and entireleaf morningglory or common cocklebur control in either tillage system. For weed control and soybean yields comparable to weed-free controls, postemergence broadleaf herbicides were required in both tillage systems following the soil-applied herbicide programs, alachlor plus linuron and alachlor plus metribuzin. Postemergence herbicide programs provided excellent season-long annual grass and broadleaf weed control when sethoxydim was applied separately from the broadleaf herbicides. Antagonism of large crabgrass control resulted when sethoxydim was tank mixed with postemergence broadleaf herbicides, compared to separate applications of the postemergence grass and broadleaf herbicides. In three out of four studies, soybean yields in handweeded controls were similar between tillage systems.

Tillage System

Tillage system is one of the factors that influences crop yield. The aim of the research was to determine the influence of the basic tillage systems on the change in soil fertility, yield and quality of corn grain in the soil and climatic conditions of the central zone of the Krasnodar Territory. The surveys were conducted in 2018–2020 on the experimental fields of the FSBSO “National Center of Grain named after P. P. Lukyanenko”. Soil – chernozems leached. All the experiments were carried out according to the standard methodology. In a stationary experiment, observations were performed to study several tillage practices: conventional tillage (25 cm depth plowing), mulch tillage with soil decompaction (reduced tillage done with a chisel plow to a depth of 32 cm for row crops), mulch tillage (deep tillage is excluded, disking to a depth of 10 cm twice or thrice is used instead). Plowing to a 25 cm depth improves the bulk of the soil in the 0–30 cm layer. However, chiseling to a depth of 32 cm and disking to a depth of 10 cm twice or thrice caused soil compaction. Standard tillage practice led to a decrease in the number of agronomically valuable aggregates (61.1 %) and their water resistance (59.4 %) compared to soil decompaction and minimum-tillage systems. The highest rates of productive moisture reserves were on the plots with traditional tillage and decompaction (140.6 and 141.5 mm, respectively, which is 14.7 % higher compared to the minimum mulching). The studied soil cultivation systems did not affect “1000-grain weight” but significantly affected the yield of grain from one ear (124.3 g) and the number of formed ears per one plant (1.04 pcs.). The corn yield on the fields with traditional and decompaction tillage methods was 56.9 and 55.9 c/ha, respectively; on minimum-tillage system, it decreased by 4.8 %. Protein content in grain harvested from the plots with traditional tillage practice was 11.4 %, which is higher compared to the minimum-tillage system. No significant differences were detected for crude ash and dry matter.
