Topical Outline Introduction Importance of legumes Recent trends in yield, production & area Classification of legumes
Legumes (Pulses) Latin word “legere” = to gather family Leguminos a e or ( Fabaceae) Fruits enclosed in pods containing several seeds
2 nd world’s largest family after grasses consists of about: - 750 genera; -19,000 species (herbs, shrubs, trees, & climbers ) grown for >6000 years
- dicots: seedling has 2 cotyledon leaves –Most of the seed’s protein is stored in the cotyledons –Leaves have netted veins
flowers have 5 petals, which are bilaterally symmetrical fruits in pods containing several seeds
Roots have nodules containing the nitrogen-fixing bacteria
Food Legumes important & diverse role in farming systems diet of resource poor people achieve 3 developmental goals reducing poverty improving human health & nutrition & enhancing ecosystem resilience
Importance & Uses fix atmospheric N help alleviate degraded soil maintain soil fertility & reduce need for fertilizer thus essential in agricultural systems towards sustainable cropping systems reduce pest and disease incidence
With capability to fix nitrogen: Bacteria in root nodules convert nitrogen gas into usable forms make legumes the most important source of protein in the plant world make them good natural fertilizer
Diverse uses include: timber medicine forages/feeds food Honored as “International Year of the Pulses” FAO (2016)
Grain legumes, sources of: protein concentrates (feeds) oil crops for cooking biofuel industrial uses (soysauce, soya milk, etc) of historical & present day importance especially with climatic change & population growth
