The effect of N and P on seedcotton yield boll andfiber properties of three Cultivars were studied during
1984 and 1985 seaso The results showed that N is an
important factor affecting seedcotton yield/fad., number
of open boils/plant1 boil weight and length parameters.
P applied had a signifjca effect on seedcotton yield
and its macrocomp(,nents given above. Differences among
cultivars were signifjca for number of open boils/plant,
boll weight lint percent, staple length, fiber finesa and
strength. Fiber properties were not affected by applied
P in the three studied cultivera. A signifjca cultivar
x N interaction was detected for seedcotton yield/fad.
for all cultjvars. And significant N x P x cultivar inter
action was detected for the number of boll/plant.
