Abstract
The Egyptian cotton (Gossypium barbadense L.) cultivar “Giza 86” was grown on a clay soil at Water Management Research Station at El-Karada, Kafrelshiekh, Egypt, during 2009 and 2010 seasons, to study the effect of five irrigation levels and two planting patterns on growth, yields and yield components and some water relations. Irrigation was applied every 14 days with different water amounts equal to 110, 100, 90, 85 and 80% of soil moisture content in root zone (0-60 cm depth) of field capacity (FC). The two planting patterns gave two distributions of the optimum plant population for this cultivar (51852 plants /feddan) on one side of 60 cm ridges or two sides of 90 cm beds. There were no significant differences between the two planting patterns in dry weight per plant, leaf area index (LAI), crop growth rate (CGR), final plant height, number of open bolls per plant, boll weight, seed index, lint %, seed oil % , seed cotton yield , lint yield and oil yield in both seasons. Application of irrigation water every 14 days interval with different water amounts had a significant effect on all growth and agronomic traits in the two seasons. Adding irrigation water with amount equal to 110% of soil moisture content of FC resulted in a significant increase in dry weight per plant, LAI, CGR and plant height, number of open bolls per plant, boll weight, seed index, lint %, seed oil % , seed cotton yield , lint yield and oil yield compared * Corresponding author: Hany S.
