anticipated that their comparison may throw some interesting light
on the amount of combined damage due to boll worm, jassid and
stainer attack.
ProGrRAMME oF WORK For 1926-27.
This will not be decided upon definitely until it is known whether
the additional assistant Plant Breeder will arrive from the U.K. in
time to help with the lay-out and planting of next year’s experiments.
The following, in brief, is an outline of the work to be undertaken,
if all goes well : —
1. Meteorogolical observations and recording of same.
> Growth in observation lines of some seventy varieties of Cotton,
which, to the writer’s knowledge, have not been grown in
Southern Rhodesia previously :
(a) On unmanured land; and (b) on heavily manured land, with
the object of discovering a variety or selection from a variety
which will give a dwarf or medium sized plant, when crown
in rich soil.
3. Growth in observation lines of field selections made last season
under conditions (a) and (b), as indicated above.
t Recording usual observations and measurements on selected
plants of each variety and strain, grown on the station.
A repetition of the variety trials conducted last year, with a
view to ascertaining to what extent such trials can be relied
upon.
A comparison of Cotton plants grown: (a) in the insect proof
cage, with (b) Cotton plants of the same variety grown under
field conditions.
Observation rows from seed of the different varieties, grown
under cage conditions last year, with a view to noting whether
or not any crossing has taken place.
** Increase *’ or *‘ small bulk ”’ plots, of what appears to be the
better varieties among those which were grown in last year’s
variety trials. The results of these trials are not yet to hand,
nor is 1t likely that they will give any indications when they
arrive, but three out of the five varieties appeared to be much
better than Improved Bancroft.
OTHER CROPS.
Maize was grown on the Cotton Breeding Station last year to
avold having to purchase food for the native labour. The resulting
crop yielded so well, however, that it is proposed to sell it to local
farmers, from whom there is a strong demand for seed. Potatoes,
monkey nuts and vegetables all yielded good crops: it is proposed to
continue growing them in rotation with Cotton.
