Abstract
The two succeeded experiments were carried out conducted in El-Mattana Agricultural Research Station, Luxor governorate, Upper Egypt during two growing seasons (2019 and 2020) to measure the response of variety Giza 98 cotton as a new variety towards planting date (15th March and 15th April), planting pattern (30 cm distance between 2 hills and 70 cm ridge width (P1), 35 cm distance between 2 hills and 70 cm ridge width (P2),30 cm distance between 2 hills and 140 cm raised bed width (P3), and 35 cm distance between 2 hills and 140 cm raised bed width (P4)) and nitrogen fertilizer levels (45, 60 and 75 Kg N /feddan) (feddan = 4200 m² = 0.420 hectares = 1.037 acres) under Upper Egypt conditions. Delaying planting dates from March 15th (D1)  to April 15th (D2) resulted in a reduction, while planting under 35cm between hills on raised bed (P4) produced the highest values and increasing nitrogen levels from 45 to 75 kg N/feddan exhibited a significant increase, for the values of total dry weight per plant, dry weight per bolls per plant, total of number bolls per plant and leaves area (LA) at the three sampling dates (75, 100 and 125 days from planting) in the first and second seasons, respectively. In the other side, the planting on March 15th (D1), under 35 cm distance between 2 hills and 140 cm raised bed width (P4) and using 75 kg N/feddan treatments, showed the highest values of seed index, lint percentage (Lint %) and seed cotton yield/feddan (Kantar = 157.5 kg). While planting on April 15th (D2), under 30 cm between hills on ridge (P1) and the application of 45 Kg nitrogen/feddan produced the lowest values of these properties.
