“…3 Variations in the climatic conditions, planting period, and agricultural practices engaged can impact the distribution of fungal species and infection, and the mycotoxin contamination that is associated with grains. 4 , 5 Despite an increase in the amount of land allocated to grain cultivation, this expansion has not translated into higher yields due to the detrimental impact of environmental factors and inadequate crop management practices, and lack of will from the government.…”

Contamination of maize adversely affects maize quality, yield, and export creating a gap in the attainment of food security, which is a millenium development goal in Nigeria. The study determined fungal abundance, genetic variability, and prevalence of toxigenic fungi in maize grains consumed in North Central, Nigeria. Sixty composite stored maize samples were collected and fungi were isolated and identified after which a multiplex polymerase chain reaction was used to confirm the presence of mycotoxin regulatory genes in suspected toxigenic fungi. The genetic relationship among the toxigenic fungi was determined and the genetic correlation between Aspergillus isolates was established through Restriction fragment length polymorphism (RFLP) analysis. About 389 (64.83%) of the total maize samples collected had fungal species belonging to the genera Aspergillus, Mucor, Penicillium, Fusarium, Trichophyton, and Talaromyces associated with them. Among the regions surveyed, Kogi State exhibited the highest maize contamination rate at 89 samples, accounting for 22.9% of the total samples collected. In Benue and Kogi, the genus Aspergillus exhibited the highest relative abundance, with percentages of 76.6% and 76.3%, respectively. Among its species, Aspergillus flavus and A. niger were the most predominant. Kwara State had the highest fungal diversity with a value of 1.711 ( P < .05). Benue State had 11 isolates (4.6%) with genes encoding for mycotoxin production, the highest recorded. Conversely, Nasarawa and Niger States each had the lowest count, with 4 isolates possessing such genes. Out of the 238 fungi suspected to be mycotoxigenic that were isolated, 39 have genes that encode for mycotoxin synthesis. Low divergence existed between toxigenic fungal species using the alpha diversity index. This study confirmed that the grains were contaminated with closely related fungal strains, and concluded that maize grains consumed in North Central Nigeria showed high association with fungal microbiota, including species capable of contaminating the grains with mycotoxins

IntroductionGrain family farms play an important role in promoting agricultural modernization and rural revitalization in China. Taking Hunan Province as an example, based on survey data from 400 grain family farms and agricultural multi-function theory, 24 specific indicators were selected from three dimensions-economic benefits, social benefits, and ecological benefits-to construct an evaluation system for the sustainable development level of grain family farms.MethodsThe entropy weight TOPSIS method was used to measure the sustainable development level of grain family farms in Hunan Province, and the obstacle factor diagnosis model was used to explore the main obstacle factors affecting the sustainable development of grain family farms.Results(1) The sustainable development level of grain family farms in Hunan Province was classified as good overall with respect to the classification criteria of existing relevant studies, but there were comparative differences in each dimension among the four regions (central Hunan, northern Hunan, southern Hunan, and western Hunan) of Hunan Province. (2) According to the diagnosis and analysis results of the obstacle degree, the top six obstacle factors affecting the sustainable development level of grain family farms in Hunan Province were the effective use of water resources, soil protection, and improvement efforts, the number of agricultural ecological culture inheritance activities, carbon emission management, the number of jobs provided for farmers, and adaptability to external environmental changes.DiscussionRelevant policies and systems should be formulated based on local conditions to enhance the integrity and synergy of the development of grain family farms in Hunan Province and to enhance the sustainable development ability of grain family farms in Hunan Province.
