Abstract
An analysis is made of yields from many farms in the GDR to determine the influences of production intensity, site, labour availability, costs, rainfall and the use of supplementary irrigation. Although a continuous supply of beans throughout the season is desirable sowings made later than 20 June yielded 15-30% less than sowings between 10 May and 20 June. Intensive fields yielded about 20% higher than the national average. There was a difference of about 39% between yields from poor and good sites and this relationship was constant despite annual fluctuations in absolute yields. On good sites supplementary irrigation increased yields by 10-20% in years with normal rainfall as well as in dry years.
