“…In arid and semiarid regions, growing season precipitation and weather extremes mostly affect the cash crop biomass yield (Acharya et al., 2022; Sainju et al., 2018; Vujić et al., 2021). In this study, sorghum received 573, 708, and 678 mm of total irrigation + precipitation in the 2018–2019, 2019–2020, and 2020–2021 cropping years, respectively, and had similar monthly average air temperatures.…”

Achieving high forage production—quantity and quality—could be challenging, specifically in water‐limited areas. Intensifying cropping systems with cover crops can provide agronomic and ecosystem service benefits. However, the impacts of cover crops on forage production have not been well studied. This study evaluated the effects of cover crops (grasses + brassicas + legumes [GBL], grasses + brassicas [GB], grasses + legumes [GL], and no cover crop [NCC] control) on sorghum silage [Sorghum bicolor (L.) Moench] yield and nutritive value over 3 years in a semiarid irrigated condition. Cover crops produced 2.1–6.0 Mg ha−1 of annual average harvestable biomass with similar forage nutritive value among treatments. In 2018–2019, sorghum silage yield was 38%–43% greater with all cover crops than with NCC. However, in 2019–2020, only GB had a 23% greater sorghum silage yield than NCC. The neutral detergent fiber content in sorghum silage was 4.8%–5.1% greater with all cover crops, and crude protein was 3%–8% lower with GL and GBL compared to NCC. Therefore, total digestible nutrients, relative forage quality, and milk production potential of sorghum silage were 5%–8%, 11%–19%, and 8%–16% greater, respectively, with NCC than with cover crops. This study demonstrates that replacing fallow with winter cover crops in irrigated silage production systems could provide good quality forage from cover crops without a decrease in subsequent sorghum silage yield. Sorghum silage quality slightly decreased with cover cropping. Nevertheless, cover crop integrated systems could be an alternative for farmers facing declining water availability for irrigated crop production.

“…Therefore, predicting optimal plant density represents a challenging task. The maize yield in the subsequent sowing directly depends on the water spent by the winter CCs and precipitation distribution during subsequent crop cultivation [80,81]. According to [82], CCs may have a more significant potential to reduce drought stress in maize after longterm use in systems with less soil disturbance.…”

Maize is the most widespread and, along with wheat, the most important staple crop in the Republic of Serbia, which is of great significance for ensuring national food security. With the increasing demand for food and forage, intensive agricultural practices have been adopted in the maize production systems. In this direction, considerable research efforts have been made to examine the effects of different types of cover crops as a green manure on maize productivity; however, no consistent conclusions have been reached so far. Therefore, the objective of the present study is to examine the possibility of predicting the effects of winter cover crops (CC) integrated with different management practices on the morphological traits, yield, and yield components of maize. The experiment was carried out on chernozem soil from 2016 to 2020 as a randomized complete block design arranged as a split-split-plot with three replicates. The pea as a sole crop (P) and the mixture of pea and triticale (PT) are sown as winter CC with the following subplots: (i) CC used as green manure, and (ii) CC used as forage and removed before maize sowing. The artificial neural network is used for exploring nonlinear functions of the tested parameters and 13 categorical input variables for modeling according to the following factors: CC, way of using CC, N fertilization, and year. The computed maximums of plant height, number of leaves, number of internodes, plant density, number of ears, grain yield, 1000-grain weight, hectolitre weight, dry matter harvest residue, harvest index, leaves percentage, stems percentage, and ears percentage are as follows: 232.3 cm; 9.7; 10.2; 54,340 plants ha−1; 0.9; 9.8 t ha−1; 272.4 g; 67.0 kg HL−1; 9.2 t ha−1; 0.52; 18.9%; 36.0%, and 45.1%, respectively. The optimal result is obtained with peas used as green manure, with 50 kg N ha−1 and in the climatic conditions of 2018. Consequently, maize production under subsequent sowing periods can be successfully optimized by adapting selected management options for higher yield accomplishment.

“…In Serbia, organic farming has been practiced since the early 1990s [13] and has developed further since then. Studies in Serbia have shown that the use of cover crops has many positive effects on soil and plant quality as well as on the environment [14][15][16][17][18][19]. However, there are still many questions that need to be investigated and verified for the region.…”

Sustainable farming is one of the priority goals of the “4 per 1000” concept with regard to the preservation of soil fertility and carbon sequestration. This paper presents a study on the use of a mixture of cover crops of self-grown oats (Avena sativa L.) and sown white mustard (Sinapis alba L.) in organic farming under the agroecological conditions of Serbia. The main objective was to identify sensitive carbon pools (microbial carbon and nitrogen, basal respiration and a number of specific groups of soil microorganisms) in organic farming with and without cover crops. The inclusion of a mixture of white mustard and self-grown oats as a cover crop led to a significantly increased biogenity of the soil compared to a control after only a few years of investigation. The number of microorganisms, soil respiration and microbial biomass carbon were significantly higher in the cover crop treatment compared to the control soil on an organic farm in Serbia. This is the first study in Serbia to investigate the effect of self-grown oats as a cover crop. Further research will incorporate a wider range of variables and factors in order to develop a sustainable and effective site-specific system for organic crop production in Serbia.
