concentration of N, P and K were higher than those in Experi-
ment 3, and vice versa in the case of Ca, Mg and Mn.
 An economic analysis of the cropping systems in Grenada
revealed that B + 2T + 3S was 54% superior to the existing
farmers' practice, (B + IT), both in the middle and high rainfall
zones, while the others proved inferior (Table 6). Therefore, it is
logical to further evaluate and refine this treatment (B + 2T +
3S) for a greater acceptance by farmers in the locality.

 On-farm research is most efficient when focused on a specific
group of farmers who have similar problems and potentials.
However, small-holders, owing to their limited acreage, may only
be able to offer scientists an area of land which is difficult to work
with, viz., low lying, too rocky, too steep or covered with perma-
nent tree crops. Consequently, it is necessary to carry out similar
trials simultaneously at a research station for evaluation of
technology under controlled conditions.
