Green manure cover crops gmcc are rapidly growing crops that cover and protect the soil. They are left on the soil surface as mulch or plowed under to enrich soil organic matter content. Legumes are prioritized for their ability to source atmospheric nitrogen through symbiosis with nitrogen-fixing bacteria.
Cajanus cajan L Millsp. Sanskrit: Adhaki, Hindi: Arhar, English: Pigeon pea, Bengali: Tur family: Fabaceae is the most important grain legume crop of rain-fed agriculture in semi-arid tropics. During the last few decades extensive studies have been carried out regarding the chemistry of C.
By integrating legumes into cropping systems, small-scale farmers in low-resource settings can invest in the long-term health and resilience of their soils. Success or failure depends largely on choosing the right legume s. With that in mind, this document presents insights on legume selection that ECHO has learned from comparing legumes across parts of Southeast Asia and through five seasons of legume screening and intercropping trials in South Africa.
Landrace legumes found in the humid and sub humid tropics with diverse climatic differences come from different groups and are found among wide range of species. The major ones include mucuna pruriens, Phaseolus lunatusSphenostylis stenocarpaMucuna sloaneiPentaclethra macrophyllaTetrapleura tetraptera and Anthonata microphylla. They have potentials for man in his food and nutrition, soil fertility improvement through nitrogen fixation and mineralization of the decayed shoots and roots in the soil.
Legumes are members of a family of flowering plants known as Leguminosae. It is one of the three largest families of flowering plants, with approximately genera and about 18, species. Legumes are a significant component of nearly all terrestrial biomes on all continents except Antarctica.
By Ana I. Climate variability and changes are utmost important primary drivers of biological processes. They are intimately associated with a wide array of abiotic stresses, highlighting the vulnerability of ecosystems and endangering biodiversity.
A variety of cultivars and the many ways they can be used in farming systems have made pigeonpea Cajanus cajan popular to small scale farmers. It is the major pulse crop of the semiarid tropics, has been used for centuries in intercropping systems, and is an ideal source of fodder, food and firewood in agroforestry systems. Pigeonpea probably evolved in South Asia and appeared about BC in West Africa, which is considered a second major center of origin.
A large number of legume species are cultivated worldwide as ornamentals in gardens, as shade treesused as living fences and firebreaks, as soil binders, green manures, fodder for livestock, forage for honey bees, food for humans, in agroforestry and reforestation for nitrogen fixationas pulp for paper production, fuelwoods, timber, and as sources of chemicals e. Many of the more common ones are listed below. Allen, O.
Plants a tropical African and Asian leguminous shrub, Cajanus cajan, cultivated in tropical regions for its nutritious pealike seeds. Switch to new thesaurus. Cajanusgenus Cajanus - erect densely branched shrubby perennials of Old World tropics; naturalized in other warm regions.
Agroforestry Systems. Tree legumes play a vital role in many agroforestry systems currently in use throughout the world. Because of their multipurpose nature they can be used to provide high quality fodder for livestock, nutrient rich mulch for crops, fuelwood and timber, microenvironment amelioration, ecosystem stability, and human food.
