1 Characterization and Delineation of Production Systems Feliciano T. Bantilan, Hama Kontongomde, Mohan Rao Palleti December 23, 1996 Methodology DEM Rainfall Average Rainfall Diurnal Temperature Range Soils: Soil water holding capacity Water Holding Capacity surface Derived Surfaces: LGP, Annual Rainfall Crop point Distribution Metgrgrid: Climatic Surfaces Cut Metgrid Values of variables relevant to growing season: Length of Growing Period, Average temperature, Minimum temperature, maximum temperature Classified variables & Their ranges Homogenous Zones classification Match Extract Analysis using GENSTAT, SAS Applying variables to metgrid 1. Transition zone from arid rangeland to rainfed, short -season millet/pulse/livestock. Eastern margins of the Thar desert 2 Subtropical lowland rainy and postrainy season, rainfed, mixed cropping. Central/eastern Indo Gangetic Plains. 3. Subtropical lowland rainy and postrainy season, irrigated, wheat-based. Western Indo-Gangetic Plains. 4. Tropical, high-rainfall rainy plus postrainy season, rainfed, soybean/wheat/chickpea. Central India. 5. Tropical, lowland, rainfed/irrigated, rice-based. Eastern India, Myanmar, Thailand, Southeast Asia. 6. Tropical, lowland, short rainy season, rainfed, groundnut/millet. Saurastra Peninsula. 7. Tropical, intermediate rainfall, rainy season, sorghum/cotton/pigeonpea. Eastern Deccan Plateu, central Myanmar 8. Tropical, low-rainfall, primarily rainfed, postrainy season, sorghum/oilsead. Western Deccan Plateau. 9. Tropical, intermediate-length rainy season, sorghum/oilsead/pigeonpea interspersed with locally irrigated rice. Peninsular India. 10. Tropical upland, rainfed, rice-based. Eastern India, Southeast Asia. 11. Subtropical, major groundnut and sorghum. China12. Subtropical, intermediate elevation, winter rainfall and rainfed, wheat-based. West Asia and North Africa 13. Transition zone from arid rangeland to short-season (less than 100 days), rainfed, millet/cowpea/ livestock. Sahelian western Africa, and southern margins of the Sahara Desert 14. Intermediate season ( days), rainfed, millet/sorghum/cowpea/groundnut- based, Northern Sudanian Zone. 15. Intermediate season ( days), rainfed, mixed, sorghum-based. Southern Sudanian Zon 16. Long-season ( days), rainfed, mixed, maize-based, Northern Guinean Zone. 17. Humid, bimodal rainfall, mixed root crop based. Southern Guinean and Forest Zones. 18. Low-lying areas prone to inundation, postrainy season, sorghum/millet/groundnut- based. Sahelian and Sudanian Zones 19. Lowland, rainfed, short-season (less than 100 days), sorghum/millet/rangeland, Sahelian eastern Africa and the margins of the Kalahari Desert. 20. Semi-arid, intermediate season ( days), sorghum/maize/rangeland. Eastern Africa and parts of southern Africa. 21. Intermediate season ( days), sorghum/maize/finger millet/legumes. Eastern and Southern Africa 22. Lowland, sub-humid, mixed, rice/maize/groundnut/pigeonpea/sorghum. Coastal areas of eastern and southern Africa. 23. Highland, rainfed, long-season, ( days), sorghum/maize/teff. Highland zones of northeastern and eastern Africa 24. Highland, semi-arid, rainfed, intermediate season ( days), mixed maize/sorghum/wheat/barley/pastoral. Highland zones of eastern and southern Africa. 25. Tropical, Upland, rainfed, maize/sorghum intercropping, Central America and Hispaniola 26. Tropical, Intermediate elevation, subtropical summer rainfall, rainfed and irrigated, sorghum, Inland valleys of Mexico and Colombia, northern Argentina 27. Tropical and subtropical coastal plains, rainfed/irrigated. Mainly Pacific coast of Central America 28. Tropical subhumid, rainfed, acidic-soil savanna, Llanos of Colombia and Venezuela 29. Intermediate-elevation, semi-arid, rainfed, acid soil. Northeastern and central Brazil ICRISAT Production System definitions Asia Latin AmericaSouthern and Eastern Africa Western and Central Africa
