Solution Dhaincha as green manure legumes in fallow season
Country India
Last update: 23/09/2006
Summary The fallow period of 60 to 70 days between wheat harvesting and transplanting of rice can be effectively used for cultivation of fast growing green manure legumes. Sesbania aculeate is a potential green manure legume for the rice-wheat system. It is raised for eight to nine weeks as pre-rice crop and incorporated into the soil during the puddling operation of rice transplantation in July. Sesbania green manure increases yield of succeeding crops but the increase is more in rice than in wheat.sesbania rostrata produces more biomass and accumulates more nitrogen than Sesbania aculeate.

Challenge/Issue Continuous growing of rice-wheat system has adversely affected the soil health and sustainability of agriculture. Farmers rarely apply organic manures and use only organic fertilizers, which have reduced the organic carbon content of soil, water holding capacity, soil aggregation etc.

Method Dhaincha crop is sown during the last weeks of March or first week of April and after 8-9 weeks crop is incorporated into the soil during the puddling operation of rice transplanting in July.
Lessons learned · A good plant establishment of dhaincha green manure crop at low cost is essential for the economic viability of such cropping systems.
· Growing of dhaincha as green manure crop during fallow period cannot be widely adopted due to shortage of irrigation water.
· High labour cost is also the hurdle in adoption of technology.
· It is difficult to fit these crops into prevailing cropping systems without disturbing a remunerative spring crop eg. spring maize and other fodder crops.
