Abstract
Tow field experiments were conducted in the Demonstration Farm of the Faculty of Agriculture, University of Khartoum, Shambat, Sudan, during 2001/02 and 2002/03 seasons using split plot design with 4 replications to investigate the effect of four water management treatments on two maize cultivars "Mugtama-45 and Giza-2 at different growth stages. Water management treatments were stress at vegetative stage (S1), stress at silking stage (S2), stress at grain filling (S3) and stress at both vegetative and grain filling stages (S4). Water stress reduced maize growth attributes such as plant height, LAI and shoot dry weight, as well as maize yield and yield components such as cob weight , grain weight per cob, number of seed per cob, 100-seed weight and grain yield per ha. Water management treatments S1, S2, S3 and S4 reduced grain yield by about 3.9, 14.95, 8.4 and 16.32% from the control (S0) respectively.
