We investigated, under field conditions and during four years (2018–2021) the effects of five irrigation levels (T1: 100% of crop water requirement; T2: 80% of T1; T3: 60% of T1; T4: 40% of T1, and T5: 0% of T1 – rainfed) in interaction with three planting densities (PD1: 54 900, PD2: 64 900, and PD3 75 200 plants/ha) on the yield, yield components and water use efficiency (WUE) of maize in Srem, Serbia. The results indicate a large year-to-year variability, mainly due to the total amount and distribution of rainfall. Water regime and PD interacted significantly. Irrigation increased grain yield 28, 34, 30 and 18% for treatments T1, T2,...

We investigated the influence of poly-glutamic acid (PGA) on ascorbic acid (AsA) and glutathione (GSH) metabolism in leaves of wheat seedlings under cadmium (Cd) stress. The results showed that Cd stress enhanced ascorbate peroxidase, dehydroascorbate reductase, monodehydroascorbate reductase, glutathione reductase, gamma-glutamylcysteine synthetase and L-galactono-1,4-lactone dehydrogenase activities, and increased AsA and GSH contents. Whereas Cd reduced AsA/dehydroascorbic acid (DHA) and GSH/oxidised glutathione (GSSG) ratios and increased malondialdehyde (MDA) content and electrolyte leakage (EL). Meanwhile, Cd stress improved Cd accumulation and...

A three-year field experiment was carried out to investigate the methane (CH4) and nitrous oxide (N2O) emissions and calculate the global warming potential (GWP) according to all energy input in response to the nitrogen (N) rate in the typical rice-wheat rotation system in Jiangsu, China. Four N treatments, including R220W180 (local practice), R220W140 (cutting 10% total N in wheat season), R180W180 (cutting 10% total N in rice season) and R180W140 (cutting 20% total N in rice and wheat seasons separately), were designed in the study. Results showed that annual CH4 emission was decreased by 25.7% in response to cutting...

Due to increased climate change, crop productivity worldwide is in danger. Drought stress is considered one of the major environmental factors in relation to world food security. Previous studies showed that arbuscular mycorrhizal fungi (AMF) inoculation alleviates drought stress in various plants. However, whether AMF inoculation efficiency is based on gas exchange or water status and whether the effects differ among plants and AMF species remain unclear. To evaluate the effect of AMF on drought stress alleviation, a meta-analysis was conducted based on random-effect models accounting for effect size variation. Results revealed that photosynthetic...

When 2-chloro-6-(trichloromethyl) pyridine (nitrapyrin) is applied alone, it typically does not significantly increase crop yield. Therefore, we combined gamma-aminobutyric acid (GABA) with nitrapyrin to address the limitations of nitrapyrin in enhancing yield. We conducted indoor incubation experiments and pot experiments in Chernozem and Calcic Kastanozem, respectively. The results demonstrated that GABA exerted an influence on the effectiveness of nitrapyrin by altering its degradation rate. In Chernozem, GABA accelerated nitrapyrin degradation, whereas, in Calcic Kastanozem, the results were the opposite. The pot experiment results showed that...
Rhizosphere and non-rhizosphere soil organic carbon and its labile fractions in alpine desertified grassland affected by vegetation restorationOriginal Paper

Grasslands are the predominant land use type in China, which is currently encountering significant desertification issues. Consequently, restoring grassland vegetation has important implications for terrestrial carbon (C) levels and, consequently, the global C balance. This study focused on Salix cupularis, the primary plant used for desert control on the eastern edge of the Qinghai-Tibet Plateau. We analysed the rhizosphere and non-rhizosphere soil up to the depth of 60 cm after Salix cupularis growth for 0–24 years, examining soil total organic carbon (TOC) and its labile fractions. Following restoration, there was a gradual increase in TOC...
