Effect of Intercropping Cotton with Maize under Different Nitrogen Rate and Different Hill Spacing of Maize

H.M.H. Mohamed, M.I.M. Salwau


Two field experiments were performed at the Research and Experiment Center of the Faculty of Agriculture at Moshtohor, Zagazig University during 1990 and 1991 seasons to study the effect of intercropping maize with cotton on yield and yield components of the intercrops and fiber properties of cotton. The experiments were laid out in a completely randomized block design with four replicates. The results indicated that intercropping maize with cotton had no significant effect on fiber properties of cotton, while highest seed cotton yield of intercropping was obtained by intercropping cotton with maize at 60 cm between maize hills and supplying plants with 120 kg N/fed. in both seasons but in this system the reduction in seedcotton yield was 8%, 31% as compared with sole cotton in 1990, 1991 seasons, respectively. Intercropping maize with cotton when maize was planted at 30 cm apart and supplied with 120 kg N/fed gave the highest yield and yield components of maize as compared to the other treatments of intercropping. The highest LER was obtained with interplanting maize between cotton rows as 30 cm apart and supplied with 120 kg N/feddan. Cotton coefficient Kc was higher than maize coefficient Km under all systems of intercropping in both seasons with one exception. Cotton was the dominant component in all systems of intercropping with one exceptional case.
