1. Highly biomass-producing green manuring crop.
2. Maximum carbon-producing crop.
3. Good crop rotation crop.
Its a topic , we have debated number of times , and some good discussion ha salready taken place. Please have a look at some of relevant publications...
Dear @Ajeet Singh I have attached two relevant PDFs; hope, both would be useful to you.
Best wishes, AKC
Green manuring crops are grown and buried in the crop field either as a pure crop or as an intercrop with the main crop. Sunhemp ( Crotolaria juncea), Dhaincha ( Sesbania aculeata), Cluster bean ( Cymopsis tetragonoloba), Cowpea ( Vigna sinensis), Khesari ( Lathyrus sativus), Berseem ( Trifolium alexandrium) Green Gram ( Vigna radiata), etc. are the common green manuring crops .
Green manure have been used in traditional agriculture for thousands of years but conventional farming systems largely rejected them as the use of fertilizers and pesticides became more common. Although they have many roles they are still often under utilised by today’s organic farmers. However, recent emphasis on reducing the environmental impact of all farming systems (stimulated by new legislation) has led to a growing interest from the conventional sector.
The most commonly grown LGM crops are sunn hemp, dhaincha, berseem (Trifolium alexandrinum), and green gram. The leguminous crops, namely, cowpea (Vigna unguiculata), green gram, black gram (Vigna mungo), pigeon pea, chick pea (Cicer arietinum), black lentil (Lens culinaris), pea (Pisum sativum), lathyrus (Lathyrus latifolius), kidney beans (Phaseolus vulgaris), tephrosia (Tephrosia purpurea), groundnut, soybean, dhaincha, and sunn hemp; woody legumes, namely, subabul, gliricidia, karanj (Pongamia glabra), and delonix (Delonix regia), have the ability to fix the atmospheric N in their root nodules. Legume crops and tree species suitable for green manuring in different agroclimatic . Dry matter accumulation by these legume crops may vary from 1 to 10 Mg/ha/year under ideal soil and environmental conditions, and the total N accumulation in the aboveground biomass ranges from 0.02 to 0.3 Mg /hr/year. Besides BNF, a green manure crop should have some desirable characteristics, viz., fast-growing habit, short duration, early onset of BNF, high N accumulation rate, high tolerance to biotic stresses (pest and disease), abiotic stresses (flood, drought, salinity, and adverse temperatures), wide range of ecological adaptability, timely release of nutrients, photoperiod insensitivity, high seed production, higher seed viability, and most importantly easiness in incorporation.
