EFFICIENT RICE BASED CROPPING SYSTEM
- 1. EFFICIENT RICE BASEDCROPPING SYSTEM IN TAMIL NADU Presented by L. U. YAAMINI PRIYA III B. Sc., Agriculture
- 2. What is thedifference between Farming system and Cropping system
- 3. Area, production andproductivity of Rice in Tamil Nadu (2014 - 15) • 5th place in India • Total area under cultivation : 17,94,991 hectares • Total production : 79,49,437 tonnes • Total productivity : 4,429 kg/ha.
- 4. TYPES OF CROPPINGSYSTEM • Mono cropping • Multiple cropping •Inter cropping •Mixed cropping •Sequence cropping •Relay cropping •Double, Triple and Quadruple cropping
- 5. • Rainfall is<750 mm/annum, mono cropping is followed. • Rainfall is >750 mm/annum, intercropping is practiced. • When water is plenty, triple and quadrate cropping is adopted. Efficient cropping systems
- 6. IMPORTANCE OF CROPPINGSYSTEM • Maintains the soil fertility • Minimize spread of diseases • Control weeds • Inhibit pest growth • Enhanced crop growth
- 7. Contd…. • Use resourcesmore effectively • Reduce risk for crop failure • Improved financial security
- 8. • Complement toeach other • Utilize available resources efficiently • Maintain and enhance soil fertility • Diverse species should be selected • The soil should be covered • Strategically plan and modify your cropping system as needed The crops selected for cropping system should be:
- 9. RICE BASED CROPPINGSYSTEM • All rice sequential cropping system (Monocropping) • Rice-Rice • Rice-Rice-Rice • Multiple cropping system • Rice-Pulse-Vegetable • Rice-Rice-Pulse • Rice-pulse-Oilseed • Rice-other cereals/millets • Rice-Pulse-Green manure
- 10. Other cropping systemsunder practice • Mixed varietal cropping system is followed in west bengal (1:1 ratio) • In Tamil Nadu mixture of autumn and winter varieties (3:1 ratio )is being practiced.
- 11. Cropping system indifferent zones of Tamil Nadu North Eastern zone: • Rice-Maize • Rice-Rice-Groundnut • Rice-Pulse • Rice-Groundnut-Gingelly
- 12. Cauvery delta zone •Rice-Rice-Pulse • Rice-Groundnut-Gingelly • Rice-pulse-Cotton • Pulses-Rice-Sunflower • Groundnut-Rice-Groundnut • Rice-Cotton+onion
- 13. North Western Zone: •Rice-cotton • Rice-Groundnut-Gingelly • Rice-Rice-Fodder sorghum • Sugarcane-Ratoon sugsrcane-Rice

- 16. Western zone • Rice-Groundnut •Rice-Cotton • Rice-Gingelly • Turmeric-Rice • Rice-Ragi-Pulses
- 17. Hilly zone • Rice-Cumbu-Gingelly •Rice-Ragi
- 18. Major cropping systemfollowed in the leading districts of Tamil Nadu and their area and production First district in rice • Cultivation : Thiruvarur (1,92,615 hectare) • Production : Thiruvarur (8,52,925 tonnes) Rice-Rice-Pulses Rice-Rice-Oilseeds
- 19. Efficient Cropping systemfor Rice • Rice-Pulses Rice-Green gram/Black gram/Cowpea • Rice-oilseeds Rice-Groundnut • Rice-Brinjal
