Food security, lowering the risk of climate change and meeting increasing demand for energy will increasingly be critical challenges in years to come. Producing sustainably is therefore becoming central agriculture food systems. Legume crops could play an important role this context by delivering multiple services line with sustainability principles. In addition serving as fundamental, worldwide source high-quality feed, legumes contribute reduce emission greenhouse gases, they release 5–7 times less GHG per unit area compared other crops; allow sequestration carbon soils values estimated from 7.21 g kg−1 DM, 23.6 versus 21.8 C year; induce a saving fossil inputs system thanks N fertilizer reduction, corresponding 277 kg ha−1 CO2 year. Legumes also competitive and, due their environmental socioeconomic benefits, introduced modern cropping systems increase crop diversity use external inputs. They perform well conservation systems, intercropping which are very developing countries low-input low-yield farming fix atmospheric nitrogen, soil organic matter facilitate nutrients' circulation water retention. Based on these functions, legume have high potential agriculture, being functional either growing or residue.

Intercropping—A Low Input Agricultural Strategy for Food and Environmental Security

Agronomy, Journal Year: 2021, Volume and Issue: 11(2), P. 343 - 343

Published: Feb. 14, 2021

Intensive agriculture is based on the use of high-energy inputs and quality planting materials with assured irrigation, but it has failed to assure agricultural sustainability because creation ecological imbalance degradation natural resources. On other hand, intercropping systems, also known as mixed cropping or polyculture, a traditional farming practice diversified crop cultivation, uses comparatively low improves agro-ecosystem. Intensification crops can be done spatially temporally by adoption system targeting future need. Intercropping ensures multiple benefits like enhancement yield, environmental security, production greater ecosystem services. In intercropping, two more species are grown concurrently they coexist for significant part cycle interact among themselves agro-ecosystems. Legumes component in play versatile roles biological N fixation soil improvement, additional yield output including protein functional diversity. But growing together requires care management less competition efficient utilization Research evidence showed beneficial impacts properly managed terms resource combined low-input use.

Iron (Fe) deficiency and toxicity are the most widely prevalent soil-related micronutrient disorders in rice (Oryza sativa L.). Progress cultivars with improved tolerance has been hampered by a poor understanding of Fe availability soil, transportation mechanism, associated genetic factors for soil (FTS) or (FDS) conditions. In past, through conventional breeding approaches, varieties were developed especially suitable low- high-pH soils, which indirectly helped to tolerate FTS FDS Rice-Fe interactions external environment internal homeostasis, have studied extensively past few decades.

Abstract Background The potential benefits of intercropping are manifold and have been repeatedly demonstrated. Intercropping has the to create more productive resilient agroecosystems, by improving land utilisation, yield stability, soil quality, pest, disease weed suppression. Despite these benefits, significant gaps remain in understanding ecological mechanisms that govern outcomes when crop species grown together. A major part plant-plant interactions takes place belowground often overlooked. Scope This review synthesises current evidence for competition, niche differentiation facilitation, with aim identifying root traits influence processes contributing enhanced performance intercrops compared monocultures. We identify a suite potentially complementary maximising intercropping. These underpin improved exploration, efficient resource use, suppression soil-borne pathogens pests intercrops. Conclusion brings together underpinning between intercropped roots, how their plasticity can promote positive outcomes. Root trait ‘ideotypes’ partners identified could be selected improvement. highlight importance examining consider both spatial temporal distribution roots rhizosphere aid complementarity through facilitation.

BNF provides many functional benefits agroecosystems. It a vital mechanism replenishing reservoirs soil organic improving availability support growth while also assisting efforts lower negative environmental externalities than N. In cereal-based cropping systems, legumes symbiosis with rhizobia contribute largest input; however, diazotrophs involved non-symbiotic associations plants or present free-living N2-fixers are ubiquitous provide an additional source fixed This review presents current knowledge free-living, symbiotic global cycle, examines regional estimates contributions BNF, discusses possible strategies enhance prospective benefit cereal nutrition.

Intercropping is an adapted farming system to optimize resource-use efficiency and crop yield, particularly in low input agricultural systems. Due the beneficial eco-agricultural effects of grain legumes, their integration mixed cropping systems such as intercropping can be more soil fertility, functioning, nutrient cycling. About 16–22% world's food provided by On smallholder farms Eastern Southern Africa, legumes has potential increase maize (Zea mays) production up 35% (e.g., Maize-pigeon pea (Cajanus cajan) intercropping). Legume-based also promote rhizobacterial community diversity health enhancing symbiotic non-symbiotic population. In rhizosphere, bacterial required improve growth both intercrops due several "direct indirect" mechanisms involving plant growth-promoting rhizobacteria (PGPR). This review aims highlight importance legume-based root-associated microorganisms particular emphasis on rhizobacteria; since whole "crop-crop-microorganism" agro-physiological performance. study discusses key role being fully synergistic with PGPR contributing yield stability under stressful conditions, notably drought deficiency. Thus, used agroecological practice ensure sustainability production.
