The future of agricultural production involves sustainable systems with a balance between nutrients in soil–plant systems. These are based on limiting the use mineral fertilizers while introducing natural sources that increase soil fertility. best example such system is plant rotation, including legumes as forecrop for cereal plants. For this reason, goal present study was to determine possibility obtaining nitrogen from air using 15N isotopes and quantity biologically fixed taken up by winter wheat cultivated succeeding plant.

The interplay between soil rhizobial bacteria and leguminous plants, particularly in Africa, has a profound impact on photosynthetic efficiency overall crop productivity. This review explores the critical role of rhizobia enhancing photosynthesis through nitrogen fixation, process crucial for sustainable agriculture. Rhizobial residing root nodules provide legumes with symbiotic that significantly boosts plant growth capacity. Recent advances molecular genomics have elucidated genetic frameworks underlying this symbiosis, identifying key genes involved nodule formation fixation. Comparative Bradyrhizobium species revealed seven distinct lineages, diverse traits linked to nodulation, photosynthesis. Field studies across Africa demonstrate inoculation can markedly increase grain yields, though outcomes vary depending local conditions legume species. Notable findings include enhanced nutrient uptake rates inoculated compared nitrate-fed plants. highlights potential utilizing indigenous improve resilience. Future prospects involve leveraging genomic insights optimize inoculants enhance productivity water-limited environments. As climate change intensifies, integrating these advancements into agricultural practices could play improving food security health Africa.

With climate change projections indicating an increase in the frequency of extreme heat events and irregular rainfall patterns globally, threat to global food security looms large. Terminal stress, which occurs during critical reproductive stage, significantly limits lentil productivity. Therefore, there is urgent need improve lentil's resilience stress sustain production. However, studies identifying heat-tolerant sources lentils are limited. To address these issues, we assessed 158 genotypes under normal late-sown conditions over two consecutive seasons. We employed eleven indices identify lines tolerant stress. All exhibited a decrease average grain yield when subjected as compared non-stress conditions, impact on crop yield. Correlation analysis showed significant positive correlation between following indices: STI, MP, MRP, YI, GMP, HM. In contrast, TOL, SSPI, PYR negative associations with conditions. Based indices, identified P13143, P13130, P13135 high-yielding both Cluster biplot display PCA also confirmed that suitability high potential environments. These can be utilized donors future breeding programs introduce genetic variations for improving tolerance lentil.

Incorporating temperate legumes is a strategy for increasing nitrogen (N) in tall fescue (Schedonorus arundinaceus (Schreb.) Dumort, nom. Cons) systems. However, when temperatures are elevated, biological N-fixation (BNF) by limited. Sunn hemp (Crotalaria juncea L.), warm-season annual legume, may provide greater N input during the warm season. This 2-year study aimed to (1) determine BNF sunn hemp-tall mixed pastures and (2) transfer from fescue. The experiment included four replicates of two treatments: (TF) intercropped with (TF+SH), arranged randomized complete block design. Response variables δ15N, derived atmosphere (%NDFA), BNF, concentration, transferred (%Ntran), stock, herbage accumulation (HA). Herbage was 16% TF+SH compared TF (p < 0.05).
