Abstract
The current study aimed to use surface and drip irrigation
systems with rates of nitrogen fertilizer and splitting of nitrogen
fertilizer rates. Two field experiments were carried out at the
Agricultural Research Farm at Al-Kawamel site, Faculty of
Agriculture, Sohag University, Sohag Governorate, Egypt
during 2019 and 2020 seasons to study effect of two irrigation
systems; surface and drip irrigation, three rates of nitrogen (N)
fertilizer and three splitting of N rates on yield and its
components of cultivar Giza 90 cotton. In each season, separate
trial was conducted for each irrigation system and the
combinations between N fertilization rates and splitting N
fertilizer rates. A field experiment was designed as randomized
complete block with split-plot arrangement of treatment with
three replications, whereas rates of nitrogen fertilizer were
allocated to the main plots and the sub-main plots include
splitting of nitrogen fertilizer. Results indicated that sowing
Egyptian cotton crop (Giza 90) cultivar in newly reclaimed
sandy soil with drip irrigation system, fertilization at a rate of
90 kg or 75 kg nitrogen per feddan with splitting to 4 doses,
caused to maximized productivity through increased
significantly the seed cotton yield 6.50 and 6.33 kentar/feddan,
respectively. Drip irrigation system saved the amount of water
required per feddan to almost a quarter (25%) compared to the
surface irrigation, under conditions of the area under the study.
