dc.description.abstract Kale (Brassica oleraceae var. Acephala D.C.) cultivar, collard green was planted in the field between October 1997 and March 1998 in the experimental plots at Maseno University college in Western Kenya. The experiment was set up to study the effect of organic and inorganic sources of fertiliser on growth and yield of kale. The kale seedlings were first raised in a nursery and transplanted 8 weeks after sowing. The treatments included farm yard manure (150 kg N.ha{sup -1}, 8kgP.ha{sup -1}), Tithonia Diversifolia (Tithonia) Leaf biomass incorporated in combination with Diammonium phosphate (DAP) (150kgN.ha{sup -1} and 30kgP.ha{sup -1}), TSithonia leaf biomass incorporated, DAP in combination with Urea, DAP in combination with calcium Ammonium nitrate (CAN) at the rate of 150kgP.ha{sup -1} and the control. Non-destructive measurements on plant height, leaf number and stem thickness were taken regularly commencing 6 weeks after transplanting. Leaf yield was assessed by both cumulative leaf weight per given area and leaf number per plant. Both organic and inorganic sources of fertiliser significantly increased growth and leaf yield of kale. In all parameters measured farm yard manure gave the best response. Tithonia leaf biomass incorporated in the soil either on its own or in combination with DAP gave leaf yields comparable increasing, organic sources which are locally available to the farmer can be alternative sources of fertiliser without compromising the yields. en_US
