The implementation of conservation agriculture (CA) remains crucial for facing interannual variability in climatic conditions that impact durum wheat production and food security. The current work was conducted to assess the effects of the tillage practice, previous crop, and nitrogen (N) fertilization rate on the agronomic and economic performances of rainfed durum wheat in a semi-arid environment in Tunisia. Tillage practices included no-tillage (NT) and conventional tillage (CT). Preceding crops were either a common vetch or a bread wheat. The N rates applied were: 0, 75, 100, 120, and 140 kg N ha−1. Our results show that, based on a 2-year experiment, tillage practices are not affecting grain yield, grain N, and gross margins. However, the N-use efficiency of durum wheat was significantly higher when wheat was grown using NT. Grain yield and N content in grain were 340 kg ha−1 and 0.34%; much higher after vetch than after bread wheat. For both tillage practices, the merit of 75 kg N ha−1 is paramount to maximize yield through a more efficient use of available N. Our results highlight the importance of no-tillage-based CA combined with rotation, including vetch, on enhanced yields, N-use efficiency, and gross margins. These findings provide the evidence of the positive impact of CA for rainfed durum wheat under semi-arid Mediterranean conditions.

Agricultural production is a crucial part of policy issue in preventing depopulation of mountainous areas across Europe. However, soil and climate conditions are limiting yields and profitability of crop production in these regions. The European Union (EU) subsidizes agriculture in mountains by special payments (Less Favoured Area (LFA) subsidy) when areas match law-specified natural handicaps. This study aims to assess whether LFA subsidy in Poland is sufficient to cover losses caused by lower yields of crops cultivated in a mountainous region of Poland (Low Beskid Mountains in Carpathians) compared to lowland regions (non-LFA areas). The results indicated that LFA subsidy was adequate for crops (facultative wheat, winter wheat, field bean and spring barley) grown in the years 2015–2018.

The study aimed to evaluate the changes in the quantitative composition of a soil bacterial community near a municipal waste landfill, and attempted to use a bacteriological coefficient to assess the degree of soil degradation. The research was carried out near a landfill site located in southern Poland. Soil samples were collected from plots on which spring wheat, field bean and potato were cultivated. Microbiological analyses included the determination of the total number of bacteria in active and dormant (sporulating) stages. The highest ratio of sporulating bacteria in relation to vegetative bacteria was found in the reclaimed sector of the landfill site. The proposed bacteriological indicator of soil quality (i.e., the ratio of the number of sporulating bacteria to the number of vegetative forms) seems to be a good index for the assessment of soil quality near the landfill site.

Abstract Interseeding a legume, such as alfalfa (Medicago sativa), into bermudagrass (Cynodon dactylon) for baleage production can improve forage quality, reduce supplementation needs, and minimize production losses. The objective of this research was to compare the nutritive value and yield of bermudagrass with and without interseeded alfalfa when produced as baleage. This study was conducted at the University of Georgia Coastal Plain Experiment Station in Tifton, GA, on an established field of ‘Tifton 85’ (T85) bermudagrass. Ten 0.2-ha plots were randomly assigned to either T85+N or T85 interseeded with ‘Bulldog 805’ alfalfa (T85+Alf). T85+N received N fertilization (84 kg N/ ha) four times each growing season. Plots were harvested at early bloom stage every 28 to 35 days from 2016 to 2018, baled at 40–60% moisture, and individually wrapped. At each harvest, plots were evaluated for botanical composition and forage yield, and bales were sampled prior to wrapping for nutritive value analysis. Plots were also evaluated for botanical composition using the point-transect method 10 days post-harvest. Data were analyzed using mixed models and least significant differences at α = 0.05. Although seasonal yields were greater in the T85+N during year 1, alfalfa-bermudagrass plots produced at least one additional harvest each season of the study, and on average 8 cuttings per season each year following establishment. Ultimately this contributed to greater (P < 0.0001) cumulative yield in the alfalfa-bermudagrass treatment (34,783 vs. 25,608 kg/ha, respectively). Analyses of nutritive value through near-infrared spectroscopy (NIR) show that CP and in-vitro true digestibility (IVTD) were greater (P = 0.005 and P = 0.034, respectively) in the alfalfa-bermudagrass treatment than the bermudagrass-only treatment (14.0 vs 11.4% CP and 66.7 vs. 60.2% IVTD, respectively). Improvements in seasonal yield and nutritive value makes bermudagrass interseeded with alfalfa a viable option for baleage producers in the Southeast.

Species in the Brassicaceae family, hence forth brassicas, such as forage kale [Brassica. oleracea L. convar acephala (DC)], swede (B. napus L. var. napobrassica), turnip [Brassica rapa L. var. rapa (L.) Thell], and hybrids (B. rapa L. × B. pekinensis L. or B. rapa L. × B. oleracea L.), have become an important source of forage for grazing worldwide. One of the limitations of forage brassicas is the relatively higher water content and low forage yield in rain-fed environments. The objective of this study was to determine swede and kale forage yield and nutritive value response to various nitrogen (N) and sulfur (S) fertilization rates. The study was conducted at two experimental field sites in North Dakota in 2012 and 2014. Kale cv. Maris Kestrel and swede cv. Major Plus and five N rates (0, 50, 100, 150, and 200 kg N ha−1) and two rates of S (0 and 40 kg S ha−1) were evaluated. Swede total forage yield was greater than kale across all nitrogen and sulfur rates. Compared with no N fertilization, N fertilization increased total leaf and root/stems yield and nitrogen accumulation in leaves, roots, and stems. Sulfur did not affect forage yield. Forage nutritive value was greater in swede than kale due to a higher proportion of edible root compared with kale’s higher proportion of fibrous stems. Nitrogen and sulfur interacted with some forage nutritive components. This study results suggest that growers will benefit from greater forage yield in kale and swede if they fertilize with N up to 200 kg N ha−1. Forage yield and nutritive value of swede and kale in the northern Great Plains are novel results, since these crops are not grown for forage and represent an interesting and valuable new alternative for beef cattle growers.
