Abstract

Two field experiments were carried out at the Research Farm of Nasser’s Faculty of Agricultural Sciences, University of Aden (Delta Tuban) Lahej Governorate, during two seasons 2017/2018 and 2018/2019, to study the effect of three sowing dates (6/11, 6/12 and 6/1) and three plant densities (56, 67 and 83 thousand plant/Ha) on the growth and yield characteristics of maize. The experiments were performed in split-plot design with three replications. The results could be summarized that the first sowing date (6 November), significantly surpassed, was higher in all growth traits compared to the late sowing date (6 January) in both seasons. The increase in plant density to 83 thousand plants/ha resulted in a significant increase in growth traits, except for stem diameter and leaf area which was decreased in both seasons. The interaction between sowing dates and plant density significantly affected all the studied traits.
