Abstract :

Two experiments were conducted at Kassala Research Station, Experimental Farm at Takroof, Gash Irrigated Scheme, Kassala State, Sudan, during two successive winter seasons of (2015and 2016), to study the effect of three Sowing methods (Ridge, Flat and Local Farmer’s Method), three Intra-row spacing (20, 30 and 40 cm) on yield and yield components of three maize (Zea mays L.) varieties namely Hudeiba-1, Hudeiba-2 and Variety113. The treatments of the experiment were conducted by using split plot arrangements based on a randomized complete block design with three replications, sowing methods were assigned as the main plots, the intra-row spacing as the subplots and the varieties as the Sub-subplots. The data were recorded for nine yield and yield components. Results revealed that sowing methods significantly affected most of the studied characters during both seasons. Ridge sowing method scored the higher rates of ear number/plot and number of seeds/row. Intra-row spacing also significantly affected most of the studied characters and 20 cm intra-row spacing gave higher levels of ear number/plot, number of seeds/ear, seed yield and hay yield. The varieties significantly affected ear length, ear diameter, number of rows/ear and number of seeds/row in the first season, ear number/plot was significantly affected by the varieties during both seasons, variety113 scored higher rates of ear/length, ear diameter, ear number of rows/ear and number of seeds/ear. In addition, the variety113 scored the higher rates of grain yield during 2015 and 2016 which amounted 1683 and 1766 Kg/ha, respectively. Grain yield was significantly affected by intra-row spacing of 20 cm and scored (1767 Kg/ha) during the first season, while 30 cm inter-row spacing scored higher levels of grain yield during the second season which amounted (1687Kg/ha). Accordingly, Variety113, grown on ridge and with intra-row spacing of 20 or 30cm gave the highest maize grain yield in Gash Scheme.
