Agro-climatic condition and productivity distribution pattern of sugarcane in India was studied to delineate the reasons for variation in sugarcane production, yield and distribution of area from place to place and year to year. It was found that prominent sugarcane growing soils of the country are recent alluvium, red sandy, medium black, red loamy and deep black soils but highest yield has been observed in coastal loamy soil. Soil-climatic factors influencing sugarcane yield significantly are found to be organic matter content, cation exchange capacity and pH of soil and mean annual minimum temperature. Higher sugarcane yield was observed at the places where pan evaporation and bio mass productivity potential are higher whereas higher irrigation water use efficiency has been recorded at the places of higher moisture availability index. Based on sugarcane yield contours the entire country has been classified in low, medium, high and very high sugarcane productivity potential zones. Models have also been developed for each zone to predict sugarcane yield based on mean annual weather parameters.
