Abstract :

Two field experiments were conducted at Kassala Research Station, Experimental Farm at Takroof, Gash Flush Irrigated Scheme, Kassala State, Sudan, during two successive winter seasons of 2015 and 2016, to study the effect of three Sowing methods namely: Ridge, Flat and local Farmer’s Method, three Intra-row spacing 20, 30 and 40 cm on growth and yield of three grain maize (Zea mays L.) varieties, namely Hudeiba-1, Hudeiba-2 and variety113. The treatments of the experiments 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 maize varieties as the sub-subplost. The data were recorded for ten growth and yield characters during both seasons. The statistical analysis showed that sowing methods were significantly affected population density and hay yield during the first season and plant height during the second season. Ridge sowing method exclusively scored higher rates of all measured characters with exception of leaf length. Flat SM scored the highest level of grain yield during both seasons and they amounted (1732 and 1740 kg/ha, respectively). Statistical analysis of variance showed that population density, plant height, stem diameter, 100 seed weight, seed yield kg/ha and hay yield ton/ha were significantly affected by intra-row spacing during the first season. On the other side, leaf number and leaf area index were highly significantly affected by intra-row spacing during the second season. The space of 30 cm inter-row spacing scored the higher rates with respect to leaf number, leaf area index, stem diameter, 100 seed weight and seed yield Kg/ha. Statistical analysis revealed that population density, leaf number, 100 seed weight in and hay yield tons/ha were significantly affected by the varieties during the first season, leaf length during second season and Leaf area index during both seasons and all characters scored higher rates with respect to variety 113. Accordingly, Variety113, grown on ridge and with intra-row spacing of 20-30 cm gave the highest maize grain yield in Gash Scheme, Sudan.
