1. General Description French beans which may otherwise be known as string, snap or dwarf beans are grown all year round in frost free areas. Yields are maximized when temperatures lie between 15 to 28°C and some pollination problems may occur if temperatures fall to 4°C or go above 35°C. 2. Soils Deep, well drained soils are preferred with an ideal pH of 5.5 to 6.5 (CaC 12 ). All soils must be analysed before planting, so that corrective measures may be taken before a problem becomes noticeable. 3. Fertilization As a general guide, apply 800 to 1000kg/ha Compound A, B, C on lighter soils and 400 to 500kgs/ha on heavier soils. The amount of top dressing used, and frequency of application varies depending on soil type. On sandy soils up to 300kg/ha. AN can be applied split on a weekly basis starting from week 3 or 4 and should continue well into flowering and pickling. Less AN would be required on heavier soils and the time between applications may be longer. Ad
