Two field experiments were carried out during 1984
and 1985 seasons at the Research and Experimental Station
at Moshtohor. The aim of this study was to investigate
effects of spacing between hills, and number of plant/hill
on yield, yield components and fiber properties of cotton.
Each experiment included 18 trearjzents which were
the combination of six spacings and three treatments as
to number of plants/hill. Results could be summarized as
follows:
1— Increasing number of plants/hill signifiantly increased
seedcotton yield/fad. Nevertheless, seedcotton yield/
plant, weight of boll and number of boils/plant signif i—
cantly decreased with increasing number of plants/hill.
2— Yield, mador components, namely, boll weight, number
of boils/plant and seedcotton yield plant were greatly
affected by distance between hills and were positively
correlated with wider spacing. The highest yield of
seedcotton/fad. was obtained when hills were spaced
30 cm apart on the ridge. Thereform, with Giza 75
variety, hills spaced 30 cm appeared to b. the most
recommendable.
3— The effect of the interaction of bill spacizi9 and
number of plants/hill was significantly on Beedcotton
yield/fad., seedeotton yield/plant, boll weight and
number of boils/plant.
