“…According to Ghassemi-Golezani and Lotfi [23] drought stress at reproductive stage shortens seed filling period and reduces yield components (NP, number seed per plant, SWP and TSW), thus resulting in SY reduction. The high variability in precipitation distribution and its amount during growing season explained 62% and 36% of inter-annual variability of soybean yield worldwide [24,25], and so in Serbia 57.2% [5]. Besides, soybean is sensitive to lower relative air humidity, which was due to the drought, also present in the first year (data not shown).…”

“…As it was previously mentioned, the growing season is an important factor, which caused variability in examined parameters, particularly its interaction with N fertilization, inducing significant variation of all parameters, as well as interaction with genotype which was important for FPH, NN, SWP, TSW, SY, CPY, COY, and RUE. This is of particular importance, considering early soybean growth, especially during stressful periods, when germination and sprouting are difficult [4,5,21], reflecting further on vegetative growth through low FPH, NN, and NP values, and yield parameters, such as SWP, TSW and SY. This study in parallel showed that observed trend did not affect only growth and yield parameters, but also seed quality, by lower CPY, COY, as it was previously described by Ghassemi-Golezani and Lotfi [23].…”

“…In Serbia, domestic cultivars with a high yield potential of about 6 t ha −1 dominate in the sowing structure [4]. However, average soybean seed yield in Serbia is unstable and could vary between 1.2 t ha −1 (2000) to 3.6 t ha −1 (2014), as a result of insufficient and unequal precipitation during the growing season [5]. The exploitation of genetic potential is possible with cultivation of genotypes suitable to different climatic conditions and application and adoption of modern agro-technology in production.…”

The main nitrogen (N) sources in soybean production originate from soil fixing bacteria Bradyrhizobium spp. and from mineralization of soil organic N. These sources of N are often not sufficient to cover the N needs of the soybean. The present two-year field study aimed to evaluate the effects of soybean genotypes (Valjevka and Galina) and rates of starter fertilizer N (0, 30, 60, and 90 kg ha −1 ) on quantitative and qualitative parameters and on rain use efficiency (RUE) under contrasting weather conditions in the Pannonian region of Serbia. A field study conducted during two different growing seasons: first year with unfavorable weather conditions and second year with favorable weather conditions. As expected, the quantitative parameters, oil content, and RUE were higher in the year with favorable growing season, the second one. According to measured parameters, the genotype Valjevka performed higher yield potential as compared to the genotype Galina. The highest values of quantitative parameters and RUE were recorded at 60 kg N ha −1 , protein content at 90 kg N ha −1 and oil content 0 kg N ha −1 (control). This study suggests that proper genotype selection and application of 60 kg N ha −1 as a starter dose with rhizobial inoculation could contribute to the high yield, while protein could be altered by N amount, independently on genotype.

“…The typical soybean planting date in eastern Germany is from late April to mid-May [8]. However, soybean following crimped rye (system (B)) was planted during late May in this study to allow the cover crops to reach anthesis, thus facilitating better roller-crimper efficacy [17,27,[34][35][36][37][38][39]. This delayed the planting date of soybean and subsequently limited the yield potential [40,41].…”

“…In dry years, the plants were often extremely short, and the lowest pods were very close to the ground, which increased losses during harvesting [37,38,40,42]. Mandić et al [39] pointed out the importance of rainfall for soybean grain yield in north Serbia. Their study concluded that soybean grain yield had a strong positive relationship with the amount of rainfall during the growing season, especially in May, July, and August.…”

Soybean in No-Till Cover-Crop Systems

et al. 2019

Introducing agro-ecological techniques such as no-tillage systems with cover crops in rotations with soybean (Glycine max (L.) Merr.) could provide more resilience to changing climatic conditions and, at the same time, reduce soil erosion, nitrate leaching, and weed density in the main crop. However, there are challenges in introducing no-tillage techniques in crop systems in Europe as there is little quantitative knowledge about the agro-economic impact. The objectives of this study were to evaluate the agronomic and economic impacts of three soybean cropping systems involving a rye (Secale cereal L.) cover crop prior to soybean, i.e., two no-tillage systems; either herbicide-free with crimping the rye or herbicide-based without rye crimping and one plough-based in which rye was cut as green silage. The impacts of these cropping strategies were compared in a three-year cropping system experiment at a research station in north-eastern Germany with and without irrigation. The following parameters were measured: (1) cover crop biomass; (2) weed biomass; (3) soybean plant density; (4) soybean grain yield; and (5) gross margin of the cropping system. The results showed that all three soybean cropping systems can effectively suppress weeds. System (C), the no-tillage herbicide-based system, produced the lowest rye biomass and highest soybean yield; system (B), the no-tillage herbicide-free/crimped rye system, produced the highest rye biomass and lowest soybean yield compared to system (A), the standard cutting/plough-based system. The differences in rye biomass and soybean yield observed between the three systems could be mainly attributed to the timing of the cover crop termination and the soybean sowing date. The gross margin was highest in system (C), due to the high soybean grain yield. The low soybean grain yield in system (B) resulted in lower revenues and gross margins compared to systems (A) and (C), although system (B) could be economically attractive in organic farming with higher prices for organic soybean. In the particularly dry year 2016, gross margins were higher when soybean was irrigated compared to the rainfed cultivation, due to significantly higher grain yields. Before recommending the application of the no-tillage with cover crop technique for the conditions tested in north-eastern Germany, more investigations on the benefits and risks of this technique are needed. Further research needs to focus on maintaining a high rye biomass as well as on ensuring an early soybean planting date. Optimizing the crimping and drilling equipment is still required in order to develop good management practices for no-tillage herbicide-free systems in European conditions.

Growth and yield responses of soybean according to subsurface fertigation

To increase soybean [Glycine max (L.) Merr.] yield, appropriate amounts of water and fertilizer are required at optimal times from sowing to maturity. This study was conducted to investigate how soybean growth and yield were affected by irrigation and fertigation using a subsurface drip system, which consisted of a buried (40‐cm underground) drip pipe that can be used in a semipermanent manner without affecting agricultural work on the ground. The amount of water required for the fertigation treatment was determined to be 176 t ha−1 with the sandy loam soil in this experimental field. Fertigation treatments based on 176 t ha−1 were carried out as topdressing applications and were applied through the subsurface drip system based on the fertilizer concentration (nitrogen only: N 20, N 40, N 60 kg ha−1, or compound fertilizer, that is, NPK 1/2 [half of the standard fertilizer amount applied as 16–16–18]). The other treatments included irrigation only and control (nontreatment). The results indicated that the N 20 treatment was the most effective, increasing yield by 83% compared with the control, whereas the N 40, N 60, and NPK 1/2 treatments produced slightly lower yields. In terms of fertigation, an excessive fertilizer concentration increased the growth of aboveground parts but reduces nodulation and yield. These results highlight the effectiveness of fertigation as a form of topdressing fertilization using a subsurface drip system for achieving a high yield and stable soybean production.
