Item Camber Bed Cultivation of Ground-Water (Vlei) Soils I-Experimental Crop Yields(1959) Robinson, J.B.D.; Evans, H.R.; Brook, T.R.; Department of Agriculture, KenyaThe system of raised bed cultivation for clay soils with impeded drainage termed Camber Bed cultivation, has now been under trial at the Coffee Research Station, Ruiru, Kenya, for almost five years. In the previous paper (Robinson et al. 1955) the principles of this cultivation system were described in some detail, together with the method for carrying out the cultivation in the field. At the same time experimental yield data from a 21 factorial nitrogen X phosphorus X cattle manure trial which was cropped with maize (Yellow Durum) in the long rains, 1954, and with beans (White Haricot) in the short rains. 1954, were recorded and discussed in detail.Item Camber Bed Cultivation Of Ground-Water (Vlei) Soils(1959) Evans, H.R.; Robinson, J.B.D.; Brook, T.R.The system of raised bed cultivation for clay soils with impeded drainage termed Camber Bed cultivation, has now been under trial at the Coffee Research Station, Ruiru, Kenya, for almost five years.

This experience is in common with that of most other pineapple-producing countries of the world. Though crop rotation appears to offer a solution, knowledge of the form that this should take is lacking. While steps have been taken to acquire this knowledge, the rapid expansion of the pineapple industry necessitated an interim answer to ensure the productivity of replant crops.Item Notes on Kenya Agriculture: IV.—Fruits and Vegetables.(1958) Jackson, T.H. ; Bennison, R.H.; Evans, H.R.; Department of Agriculture, KenyaA regular evenly distributed supply of soil water is required, with high temperature and humidity in the absence of wind. Where there is a danger of high winds dwarf types should be grown. The ideal soil is a deep loam permitting free root development. Rainfall 45-100 in. Altitude 0-6,000 ft.
