Possible effects of different types of agricultural wastes on food security and mushroom (Pleurotus ostreatus) production.

One of the new waters, and environmentally friendly agriculture initiatives in Peru is to encourage the utilization of agricultural waste, because low agricultural output is a threat to food security there. The purpose of this research was to evaluate the effect of harvest residues on the basidiocarp production of the fungus Pleurotus Ostreatus, in Acobamba-Huancavelica. The trial had a completely randomized design, and the treatments included T1, barley stubbles; T2, wheat stubbles; T3, pea stubbles; T4, broad bean stubbles; and T5, quinoa stubbles. The research was quantitative in nature, taking the form of an experiment with an applied, explanatory level of design. The recorded data was tabulated and analyzed with analysis of variance, as well as Tukey's test (α:0.05), for which the statistical software Infostat was used. The results are presented in tables and graphs for a better interpretation. As main results, it was obtained that the time (colonization), diameter (stem, pileus), length (stem) and weight (basidiocarps), present statistical differences between treatments showing significant enhancement in all parameters. Despite a numerical difference, a Tukey average comparison test revealed that there was no statistically significant difference between the averages for the variable time for fungus colonisation, suggesting that the treatment T5 in which quinoa substrate showed the greatest average. Treatment T4 in which broad bean stubbles were used gave the most low-average. In conclusion, increment in all parámeters were noted in all treatment of Pleurotus basidiocarps ostreatus under Acobamba conditions.

Photosynthetic modification of plants through recent technologies: a valuable way to ensure crop fortification.

The 2030 Sustainable Development Goals of the United Nations include a strong emphasis on ending hunger worldwide. According to the 2019 Global Food Security Index, while 88% of countries claim there is sufficient food supply in their country, the sad reality is that 1 in 3 countries is facing insufficient availability of food supply, which means that in those countries, more than 10% of the population is malnourished. Since nutrition is crucial to leading a healthy life and satisfying food security needs, several governments have turned to national nutrition surveys to gauge the extent of malnutrition in their populations. Plants are able to grow, develop, and store nutrients by photosynthesis, which convert light into chemical energy through cell redox regulatory networks. A photosynthesis system's electron flow may be adjusted to accommodate varying light and environmental circumstances. Many techniques exist for controlling the flow of electrons emitted during light processes in order to save or waste energy. The two protein molecules TROL and flavoenzyme ferredoxin (oxidoreductase+NADP) (FNR) interact dynamically to form an excellent molecular switch capable of splitting electrons from the photosystem. The TROL-FNR bifurcation may be limited by either generating NADPH or preventing reactive oxygen species from propagating. TROL-based genome editing is an experimental method for enhancing plant stress and defensive responses, efficiency, and ultimately agricultural production.

Os Objetivos de Desenvolvimento Sustentável de 2030 da Organização das Nações Unidas incluem uma forte ênfase em acabar com a fome em todo o mundo. De acordo com o Índice Global de Segurança Alimentar de 2019, enquanto 88% dos países afirmam que há abastecimento alimentar suficiente em seu país, a triste realidade é que 1 em cada 3 países enfrenta disponibilidade insuficiente de alimentos, o que significa que, nesses países, mais de 10% da população está desnutrida. Uma vez que a nutrição é crucial para levar uma vida saudável e satisfazer as necessidades de segurança alimentar, vários governos recorreram a pesquisas nacionais de nutrição para avaliar a extensão da desnutrição em suas populações. As plantas são capazes de crescer, desenvolver e armazenar nutrientes pela fotossíntese, que converte luz em energia química por meio de redes reguladoras redox celulares. O fluxo de elétrons de um sistema de fotossíntese pode ser ajustado para acomodar luz variável e circunstâncias ambientais. Existem muitas técnicas para controlar o fluxo de elétrons emitidos durante os processos de luz, a fim de economizar ou desperdiçar energia. As duas moléculas de proteína TROL e a flavoenzima ferredoxina (oxidorredutase+NADP) (FNR) interagem dinamicamente para formar um excelente interruptor molecular capaz de separar elétrons do fotossistema. A bifurcação TROL-FNR pode ser limitada, gerando NADPH ou impedindo a propagação de espécies reativas de oxigênio. A edição do genoma baseada em TROL é um método experimental para aumentar o estresse da planta, as respostas defensivas, a eficiência e, finalmente, a produção agrícola.

Uma das novas iniciativas de águas e agricultura ecológica no Peru é incentivar a utilização de resíduos agrícolas, porque a baixa produção agrícola é uma ameaça à segurança alimentar no país. O objetivo desta pesquisa foi avaliar o efeito dos resíduos da colheita na produção de basidiocarpos do fungo Pleurotus ostreatus, em Acobamba-Huancavelica. O ensaio teve um delineamento inteiramente casualizado, e os tratamentos incluíram T1, restolho de cevada; T2, soqueiras de trigo; T3, restolho de ervilha; T4, restolho de fava; e T5, restolho de quinoa. A pesquisa foi de natureza quantitativa, assumindo a forma de experimento com um nível de design aplicado e explicativo. Os dados registrados foram tabulados e analisados com análise de variância, bem como teste de Tukey (α:0,05), para o qual foi utilizado o software estatístico Infostat. Os resultados são apresentados em tabelas e gráficos para melhor interpretação. Como principais resultados, obteve-se que o tempo (colonização), diâmetro (caule, píleo), comprimento (caule) e peso (basidiocarpos) apresentam diferenças estatísticas entre os tratamentos, mostrando melhora significativa em todos os parâmetros. Apesar da diferença numérica, o teste de comparação de médias de Tukey revelou que não houve diferença estatisticamente significativa entre as médias para a variável tempo de colonização do fungo, sugerindo que o tratamento T5 em que usou o substrato quinoa, apresentou a maior média. O tratamento T4, no qual foram usadas restolhos de fava, apresentou a média mais baixa. Em conclusão, incrementos em todos os parâmetros foram observados em todos os tratamentos de Pleurotus basidiocarps ostreatus nas condições de Acobamba.
