“…Furthermore, the biostimulants available on the market are diverse and can also vary in relation to application methodologies. In this context, the study by Barbosa et al [13] reinforces the need for the development of more research evaluating how corn plants respond to different biostimulants in different field situations involving different application methodologies.…”

Climate change alters regular weather seasonality. Corn is one of the main crops affected by irregular water regimes. Due to complications in decision-making processes related to climate change, it is estimated that planting corn outside the optimal window results in around USD 340 million in losses per year in the United States’ Corn Belt. In turn, exogenous plant growth regulators have been gaining prominence due to their potential to positively influence the morphology and physiology of plants under stress. This study was based on the hypothesis that the use of plant growth regulators can assist in mitigating the adverse effects of climate change on corn plants sown both inside and outside the recommended planting period. In this context, the effects of biostimulant application on gas exchange in corn plants sown within and outside the recommended period were evaluated. The experiment was carried out in randomized blocks in a 4 × 5 × 2 factorial scheme with four repetitions. These were four sowing times, the application of the biostimulants via seeds in five doses, and foliar applications (presence and absence). The biostimulant doses were 0.00, 6.25, 12.50, 18.75, and 25 mL kg−1. The foliar application used a dose of 500 mL ha−1. Only in the period (2017/2) higher doses of biostimulants indicated a decrease in the water use efficiency of plants, suggesting the need to evaluate this variable carefully. In this regard, future studies may investigate the ideal doses and application timings of biostimulants for different edaphoclimatic conditions. In general, the combined use of biostimulants on seeds and as a foliar treatment boosted physiological activity and stimulated photosynthetic processes in corn plants. Based on these data, plant regulators can be a useful tool to mitigate the adverse effects of climate change on corn plants sown inside and outside the planting period.

A agricultura enfrenta inúmeros problemas bióticos e abióticos que afetam a produtividade agrícola, destacando-se a escassez de água como um dos mais prejudiciais. Os bioprotetores são reguladores vegetais que auxiliam as plantas a diminuírem os impactos proporcionados pelos estresses bióticos e abióticos. O presente estudo teve como objetivo identificar os efeitos dos bioprotetores na mitigação do déficit hídrico em plantas de girassol e milho. O experimento foi conduzido na Universidade Estadual de Goiás, Unidade de Ipameri. Em delineamento inteiramente casualizado, em arranjo fatorial 2 x 5 (culturas: girassol e milho e quatro tratamentos de aplicação de bioprotetores: Ct, St, Br, Hz e testemunha. Aos 20, 35 e 42 dias após a emergência as plantas receberam a aplicação de bioprotetores. Aos 50 DAE realizou as avaliações de altura de planta, número de folhas, área foliar, razão de massa foliar, caulinar e radicular, biomassa total, clorofila a, b e total e transpiração. Os bioestimulantes não mitigaram o déficit hídrico em plantas de milho e girassol nas condições de aplicação dessas substâncias durante o período de estresse, no entanto, trabalhos posteriores são necessários no sentido de aplicação dos bioestimulantes antes da imposição do déficit hídrico.
