| Abstract: | In terms of the improved Kassam-W ageningen method, calcu-lation is made level by level of the effects of light, temperature, waterproductive potentiality and soil upon the four major grain crops in theprovince. The geographic distribution of the crop productivity in sixfarming areas is given together with the prediction of the developmentof the productivity for the forty years ahead. Analysis is made of theproductive potentiality to meet the needs of the population growth,followed by the presentation of useful measures for the balance between the necessity and production of crops. |
