Summary: Optimizing nitrogen inputs is crucial for maximizing wheat yield and ensuring environmental sustainability. This study evaluated ten wheat cultivars for their yield and N-use efficiency under varying nitrogen inputs, and found that 'HD 3249' and 'HD 3117' have the potential to improve N utilization efficiency and grain yield in North-West India.

Summary: This study aimed to investigate the relationship between deep roots in winter wheat and drought tolerance, and how this relationship is affected by genotype and nitrogen fertilization. The study found that deep roots were correlated with higher grain yield, uptake of water and nitrogen from deeper layers, and tolerance to drought. Therefore, breeding efforts should consider enhancing deep rooting for more climate resilient crops.

Summary: Foliar fertilization is an important agricultural practice that can enhance soil potassium uptake by crop plants, as demonstrated in experiments with wheat and maize. By applying potassium to the leaves, the net potassium uptake through the roots increased by approximately 23% in wheat and 55% in maize. This resulted in improved phenotypic traits and enhanced photosynthetic activity in the treated seedlings. The findings suggest that foliar potassium fertilization has the potential to benefit cereal crops and should be further investigated to understand the underlying signaling pathways.

Summary: The spatial arrangement of wheat/soybean relay intercropping has an impact on growth, grain yield, nitrogen uptake, and land-use advantage. Wide strips in the intercropping system outperformed narrow and medium strips, with higher total leaf area, dry matter, nitrogen uptake, and grain yield. Additionally, all intercropping systems accumulated more nitrogen and exerted less pressure on the ecosystem than sole systems.

Summary: Life in freshwater poses osmotic and energetic challenges for organisms, particularly arthropods. The mechanisms of ion uptake from freshwater environments are still poorly understood, but the proton pump V-type H+ ATPase (VHA) and the Na+/H+ antiporter (NHA) have been proposed as potential models. This study explores the evidence for these models in crustaceans, insects, and teleost fish and emphasizes the need for further research on ion uptake mechanisms in freshwater habitats.

Summary: The study found that Karrikinolide (KAR(1)) can promote seed germination in wheat under salt stress by regulating hormone biosynthesis genes and inhibiting abscisic acid biosynthesis and signaling genes. Additionally, KAR(1) can improve root and shoot growth in wheat seedlings, as well as maintaining redox and K+/Na+ balance.

Summary: This study aimed to identify ryegrass cultivars with contrasting phosphorus (P) use efficiency and assess their associated biochemical and molecular responses. Nine ryegrass cultivars were evaluated under optimal and P-deficient conditions, and the activity and gene expression of acid phosphatases (APases) and P transporters were analyzed. The results showed that cultivars with high P acquisition efficiency were influenced by root-related responses, while cultivars with high P utilization efficiency were influenced by P transporters and APase activity in shoots.

Summary: Managing phosphorus is a global priority for environmental water quality. A study in Western Australia's Fitzgerald River catchment found that dissolved phosphorus transport was dominant, with physical filtering methods like riparian vegetation proving ineffective in restricting phosphorus transport into streams. Evidence-based fertiliser advice could help reduce dissolved reactive phosphorus losses without yield loss.

Summary: In a wheat-mungbean-rice rotation system, nitrous oxide emissions were higher in strip tillage compared to conventional tillage, with the nitrogen fertilizer rate also affecting emissions. However, strip tillage could improve soil aggregation and balance nitrogen and crop yield despite the increased emissions.

Summary: Land development is occurring rapidly on sand-dominant soils in the Lower Mekong Basin, but it poses risks of degradation. Agriculture expansion on sloping uplands and intensification of cropping on lowland landscapes are the main factors contributing to these risks. Challenges include drought-prone conditions, nutrient losses, waterlogging, and soil acidity. These constraints limit the productivity and sustainable use of sand profiles. However, site-/soil-specific management strategies, land suitability assessment, and conservation agriculture principles can help overcome these constraints.

Summary: The study found that waterlogging for 24 hours did not affect sunflower at any stage, but waterlogging for 48 and 72 hours suppressed emergence and growth at the 2 and 4-leaf stages. Waterlogging for 72 hours completely prevented emergence for early-sown sunflower, while emergence was less affected for later sowing. Shoot and root dry weight were most affected at the emergence and 2-leaf stages, not at the 4-leaf stage.

Summary: The field trial conducted in the Gangetic Plains of Bangladesh showed that strip-tillage and bed planting performed better in terms of rice and lentil yield, while strip-tillage and zero tillage were more effective for jute. Increasing residue retention led to higher crop yields across all years. Additionally, minimum soil disturbance practices such as zero tillage and strip-tillage significantly improved soil nutrient concentrations and crop yields compared to conventional tillage.
