Abstract

Two field experiments were carried out in Mallawy
Agricultural Research Station, Minia Governorate, Middle Egypt,
during 2010 and 2011 seasons to find out the effect off hill spacing
and nitrogen fertilization level on the new promising Egyptian cotton
hybrid Giza 90 x Australian (Gossypium barbadense L.,). The
experimental design was a split plot block with four replications.
The main plots were devoted to four hill spacings (20, 25, 30 and
35 cm) and the sub plots for four nitrogen fertilization levels (30,
45, 60 and 75kg N/fed.). The results indicated that hill spacing and
nitrogen fertilization levels had significant effects on no. of
sympodia/plant, earliness %, no. of open bolls/plant, boll weight and
seed cotton yield/fed while, but not on plant height, first sympodial
position, seed index and lint %. Increasing hill spacing to 35 cm
between hills significantly increased no of sympodia/plant, no. of open
bolls/plant, boll weight, seed cotton yield/fed, but decreased earliness
%. Increasing N levels from 30 to 75 kg N/fed exhibited a significant
increase in each of no. of sympodia/plants, no. of harvested plants/fed,
earliness %, no. of open bolls/plant, boll weight and seed cotton
yield/fed. The interaction between hill spacing and nitrogen level
exerted significant effects on no. of sympodia/plant, earliness % and
boll weight in both seasons, no. of open bolls/plant in the first season
and seed cotton yield/fed in the second season. The combination
between 35 cm hill spacing and 60 or 75 Kg N/fed. gave the highest
averages of no. of sympodia/plant, boll weight, no. of open bolls/plant
and seed cotton yield/fed. The effect of hill spacing and nitrogen
fertilization level and their interactions did not exhibit any significant
effect on all fiber properties under study. It could be concluded that
35 cm hill spacing and 60 Kg N/fed. could be recommended
production of this new cotton hybrid Giza 90 x Australian under
Middle Egypt location.
