Abstract:

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. INTRODOCTI Yielding capacity of any cotton variety is determined by and larga by Its genetic make-up.. Ya Lb. .latar by itself will not develop a good yield unless certain environ mental conditions are met. Of these, hill spacing and number of left-in plants per bill at thinning time determine
