Alfalfa is an important leguminous plant, yield and quality depend on the growing environment, while effects of drought and heat stress on alfalfa leaves are unknown. This study was conducted to evaluate the effect of exogenous ascorbic acid (AsA) on photosynthesis, chlorophyll fluorescence, and xanthophyll cycle in alfalfa leaves subject to under drought and heat stress. The results suggest that drought and heat stress caused decreases in the net photosynthetic rate (Pn) in alfalfa leaves, but stomatal conductance (gs), transpiration rate (Tr), and intercellular CO2 concentration (ci) were increased....

Drought is an important agricultural problem worldwide, which seriously affects the growth and yield of crops. To explore the effects of different degrees of drought on the soluble sugar content of soybeans, this study measured the soluble sugar content of two soybean cultivars at three growth stages under four levels of drought stress. The results showed that drought stress significantly affected the soluble sugar content, and there were differences among different growth stages and cultivars. At the seedling and flowering stages, the sucrose content of both Heinong44 and Heinong65 showed an unimodal trend and reached the maximum value at moderate...

To supply more insights into the roles of putrescine (Put) in alleviating salt stress in wheat crops, we explored the effects of Put on ascorbate (ASC) and glutathione metabolism, photosynthetic performance, and ion homeostasis in leaves of salt-stressed wheat seedlings. Our results displayed that salt stress increased the activities of enzymes in ASC and glutathione metabolism, including ascorbate peroxidase, dehydroascorbate reductase, monodehydroascorbate reductase, glutathione reductase, gamma-glutamylcysteine synthetase, and l-galactono-1,4-lactone dehydrogenase, which increased reduced ascorbate (AsA), dehydroascorbate (DHA), reduced glutathione...

Changing political demands requires the search for alternatives to glyphosate, which has often been used in the stale seedbed method. In three field trials between 2020 and 2023, three electrophysical treatments (XPower System, Zasso®) differing in speed, three mechanical treatments (disc harrow, rotary harrow, cultivator) and three chemical treatments (glyphosate, maleic hydrazide, pelargonic acid + maleic hydrazide) were evaluated concerning the efficacy and economic performance in stale seedbed method in Alopecurus myosuroides control. Process costs for each treatment were calculated. Furthermore, the maximum investment costs for...

Long-term field experiments provide a valuable dataset for predicting changes in soil organic carbon (SOC) stocks in different agricultural systems. The RothC-26.3 model was used to simulate changes in SOC in the monoculture of spring barley (Hordeum vulgare L.) and the Norfolk crop rotation during 1972–2100. The potential of the Gleyic Fluvisol Clayic to sequester organic carbon was investigated. The studied soil was heavily textured, with medium organic carbon content. Four management scenarios in the monoculture and six management scenarios in the Norfolk crop rotation were evaluated. Three different global climate models (MPI, MRI,...

This work aims to differentiate the rural land of Slovakia in view of the possibility of effective sunflower growing. The differentiation is based on pedo-climatic and production-economic parameters. Soil categorisation took into account the correlation between the site properties (soil and climatic conditions) and the biological and agrotechnical requirements of the crops. Sunflower requirements were included in yield databases using software filters such that a given site property excluded or limited sunflower growing, which was reflected in predicted production. The prediction was subsequently interpolated into four suitability categories: soils...

Crop residue management and water saving are the two major issues for the sustainability of the rice-wheat cropping system. Therefore, a two-year field experiment was conducted in a split-plot design to study the combined effect of three rice residues (residue incorporation (RI), residue standing (RS) and residue removal (RR) and two wheat residue incorporation (WI) and residue removal (WR) management in main plots and two irrigation regimes, i.e., flood (F) and surface drip (SD) in subplots on the growth and water productivity of direct seeded rice (DSR). During both years, RI-WI resulted in significantly higher plant height (PH), leaf area index...
