“…This problem could even be exaggerated by the exogenous factors, as the adverse weather has a larger impact on the lower tail of the yield distribution compared with the upper tail (Chavas et al, 2019). Therefore, factors affecting efficiency and productivity, including factors, such as crop rotation and diversification of crops (Volsi et al, 2022), are also expected to affect the exit decision.…”

Farm exit plays a vital role in the overall productivity growth of the industry. However, little attention is paid to the effects of different support policies on the exit decision. In this paper, we analyze and compare two subsidy schemes—direct subsidies and tax benefits in the form of the special value‐added tax regime on the exit decision. Employing a mixed‐effect logistic model and the farm‐level panel data of Ukrainian commercial farms, we found that both subsidy schemes have a similar effect on the exit decision and reduce the probability of leaving the market. However, this effect is contemporaneous only. The subsidy a farm receives in the current year does not affect next year's exit decision. [EconLit Citations: D22, Q12, Q13, Q18].

“…In Mississippi, soybean and corn are primarily produced crops in a 2‐year rotation, where canola might be a good fit as a potential double crop within this rotation. Adopting double cropping can benefit the soil health because both the crops (canola and soybean) have different nutrient requirements and rotating these crops can prevent nutrient depletion in soil (Volsi et al., 2022). Additionally, double cropping can increase the economic returns for farmers.…”

The production of canola (Brassica napus L.) in the United States is low, whereas the demand is high. Most US canola research is centered in the Midwest, with minimal to no research in Southern states including Mississippi. Therefore, a study was conducted in Mississippi to assess the feasibility of canola as a double crop with soybean (Glycine max L.) rotation and determine its optimum nitrogen (N) requirement. After canola was harvested, soybean was planted within the same experimental plots. In total, six N treatments (0 [control], 34, 67, 101, 135, and 168 kg N ha−1) were applied to canola and replicated four times across all site‐years in a randomized complete block design. The application of N increased seed yield, aboveground biomass, and N content compared to the control in canola. Across all site‐years, the highest seed yield was 1726 kg ha−1 at 168 kg N ha−1. Moreover, N uptake, plant height, and test weight were highest at 135 kg N ha−1, which were 76%, 21%, and 44% greater than control, respectively. Oil content and seed weight were inversely related to N rates indicating dilution with increased N. Overall, 141 kg N ha−1 was found to be the agronomic optimum nitrogen rate, and no further supplementation was deemed necessary to maximize canola yield in Mississippi. Additionally, the following soybean crop benefitted from the N applied to canola and produced greater yields. This study establishes that canola has the potential for double cropping without adversely affecting subsequent soybean yield, provided optimum N rates are applied.

“…Crop rotation strategy implementation may reduce the fungal infestation to some extent. However, even this strategy reduced grain production ( Volsi et al., 2022 ). Various biocontrol agents like Trichoderma sp., Mycorrhizal fungi, and Pseudomonas fluorescens demonstrated antagonism toward Rhizoctonia solani and Fusarium oxysporum .…”

IntroductionMicrobial biofertilizers or biocontrol agents are potential sustainable approaches to overcome the limitations of conventional agricultural practice. However, the limited catalog of microbial candidates for diversified crops creates hurdles in successfully implementing sustainable agriculture for increasing global/local populations. The present study aimed to explore the wheat rhizosphere microbiota for microbial strains with a biofertilizer and biocontrol potential. MethodsUsing a microbial culturing-based approach, 12 unique microbial isolates were identified and screened for biofertilizer/biocontrol potential using genomics and physiological experimentations. Results and discussionMolecular, physiological, and phylogenetic characterization identified Stenotrophomonas maltophilia BCM as a potential microbial candidate for sustainable agriculture. Stenotrophomonas maltophilia BCM was identified as a coccus-shaped gram-negative microbe having optimal growth at 37°C in a partially alkaline environment (pH 8.0) with a proliferation time of ~67 minutes. The stress response physiology of Stenotrophomonas maltophilia BCM indicates its successful survival in dynamic environmental conditions. It significantly increased (P <0.05) the wheat seed germination percentage in the presence of phytopathogens and saline conditions. Genomic characterization decoded the presence of genes involved in plant growth promotion, nutrient assimilation, and antimicrobial activity. Experimental evidence also correlates with genomic insights to explain the potential of Stenotrophomonas maltophilia BCM as a potential biofertilizer and biocontrol agent. With these properties, Stenotrophomonas maltophilia BCM could sustainably promote wheat production to ensure food security for the increasing population, especially in native wheat-consuming areas.
