- Abstract:
- ... The accident at Fukushima 1 Nuclear Power Plant in 2011 caused contamination by radioactive cesium (¹³⁴Cs and ¹³⁷Cs) in surrounding areas. After this accident, concerns about Cs contamination, including food safety, have limited industrial activities and reconstruction in Fukushima. Sorghum (Sorghum bicolor (L.) Moench) is an annual C₄ crop that can be used as biofuel feedstock due to its high bio ...

The increase of the world’s population and the decrease of arable land due to abiotic stresses, especially salinity and heavy metals, are causing growing concerns over agricultural sustainability. The application of Plant Growth-Promoting Rhizobacteria (PGPR) is considered as a useful tool to reverse such environmental stressors. The aim of the study is to investigate the growth-promoting effects ...

- Abstract:
- ... Leafy vegetables like lettuce and spinach are prone to significant post-harvest losses during handling and storage. The pre-harvest treatment of crops with biostimulants offers a sustainable strategy for reducing post-harvest losses. Earlier studies focused on the effect of plant biostimulants applied individually. In this study, we studied the efficacy of a combined application of two commonly us ...

- Abstract:
- ... Water stress is one of the main limiting factors for common bean crops, negatively affecting grain yield and seed quality. Thus, the objective of this study was to evaluate the inheritance of agromorphological and physiological traits related to drought tolerance in order to identify promising combinations. The experiment was carried out in a greenhouse with a partial diallel scheme between three ...

- Abstract:
- ... Long‐term agricultural fertilization strategies gradually change soil properties including the associated microbial communities. Cultivated crops recruit beneficial microbes from the surrounding soil environment via root exudates. In this study, we aimed to investigate the effects of long‐term fertilization strategies across field sites on the rhizosphere prokaryotic (Bacteria and Archaea) communi ...

With exposure and uptake of CECs, phytotoxicity and health of crop plants is of concern, but is poorly understood. This study evaluated the effect of low-dose, chronic exposure to a mixture of 10 CECs, including 4 antibiotics, 3 anti-infl ...

Many studies have focused on the effect of elevated atmospheric CO₂ concentration (e[CO₂]) on grain yield and quality in wheat intrageneration; however, the long-term effect of e[CO₂] over multiple generations, which will be the case for crops grown in future climate, has received little attention. The grain yield and quality were investigated in wheat after one generation (F1 harvested in 2014) a ...

A key factor influencing adoption is lack of information on disease risk. To facilitate adaptive water use, effects of set-point substrate moisture (SM) control on disease risk and water savings in containerized annual p ...

Especially, ozone (O₃) has become a critical problem since the average O₃ concentration is increasing every year by about 0.5–2% across the world. O₃ in the air affects plant growth because it mainly passes through the stomata of leaves into plants. This experiment was designed to identify the physiological, morphol ...

- Abstract:
- ... Besides oilseed rape and soybean, sunflower is one of the most important annual oilcrops. Apart from seed yield, which is the most important trait in many crops, oil yield is of utmost interest for sunflower breeders and farmers. Compared to the seed yield of sunflowers, their total biomass is often very high, and it is of great agronomic interest to increase the ratio of both parameters, which is ...

- ... Hydrogen sulfide (H2S) modulates plant tolerance to abiotic stresses, but its regulatory effects on nitrogen metabolism and chloroplast protection under nickel (Ni) stress in crop plants remain elusive. Taking this into account, we investigated the potential roles of sodium hydrosulfide (NaHS), a H2S generator, in the improvement of growth performance of rice plants under Ni stress. Results showed ...

- Abstract:
- ... Food security in Sub-Saharan Africa (SSA) is dependent on complex networks of interconnected actors and the flows of resources (biomass, capital) and information among them. However, the degree to which actors and value chains of different crops are in fact interconnected and their current systemic influence on food security are unclear. Therefore, the concept of “value webs” to better ...

- Abstract:

The use of improved biofertilisers such as rhizobia and arbuscular mycorrhizal fungi (AMF) in legume crops is a promising technology that can be an alternative source of nitrogen and phosphorus. A common problem when growing faba bean (Vicia faba L.) and other leguminous plants is the low efficiency of native rhizobial strains. Consequently, there is a need to search for efficient nitrogen-fixing ...

BACKGROUND: Among Cactaceae, the genus Opuntia is widely known for the use of its biomass as cattle fodder and in human nutrition (e.g. species such as Opuntia ficus indica and Opuntia streptacantha). In particular, O. streptacantha (OS) produces abundant mucilage and, hence, the characterization of its properties and nutritional value is important. Accordingly, determination of the dietary fiber ...

In soybean, an economically important crop that is highly sensitive to heat stress, the use of plant growth-promoting rhizobacteria (PGPRs) represents a promising strategy for countering the negative effects of heat stress. Accordingly, a novel strain of Bacillus ...
