Abstract
Two field experiments were carried out at Nubaria Agricultural Research Station,
representing the newly reclaimed desert land of North West, Egypt in Nubaria, which located
at 47 Km South West of Alexandria city in the two summer growing seasons of 2017 and
2018. The present investigation was carried out on a highly calcareous sandy loam soil to
study the effect of irrigation regimes and NPK fertilization on plant growth attributes,
earliness parameters, seed cotton yield, its components and fiber properties of Egyptian
cotton (Gossypium barbadense L.) Giza 94 cotton cultivar was used which represent long
staple Egyptian cotton category.
Egyptian clover Barseem (Trifolium alexandrinum L.) was the preceding crop in the
two seasons, which was removed after two cuttings before bloughing. Barseem is a favorite
crop before summer sowings especially, in newly reclaimed or calcareous soils.
The experimental design was a split-split plot with four replications, where the
Irrigation regimes treatments were allocated to the main plots, the sub-main plots included
