Title: Effect of Some Tillage Systems and Sowing Methods on Wheat Production in The Upper Terraces if The Northern State (Sudan)
Author: Mahgoub, Mohamed Abdalla Fudl
Abstract: A field experiment was conducted in two successive seasons (2000/2001) and (2001/2002) to investigate the effect of tillage systems and sowing methods on wheat production in the upper terraces of the Northern State.The experiments were carried out at "Jiera Agricultural Cooperative Society, El Dabba Province", 160 km south Dongola city. The treatment consisted of five tillage systems, namely disc plowing plus light disc harrowing plus leveling, moldboard plowing plus light disc harrowing plus leveling, chisel plowing plus light disc harrowing plus leveling, heavy disc harrowing plus leveling and light disc harrowing plus leveling, in addition to zero tillage as control. Each tillage system included three sowing methods, namely manual broadcasting of seeds plus cultivating (CU), manual broadcasting of seeds plus light disc harrowing (LDH) and seed drilling machine (SD). The experimental treatments were replicated three times in a split-plot design with the main plots designated to tillage systems and sub-plots to sowing methods. The measured implements parameters included, effective field capacity, field efficiency, slippage (%) and fuel consumption. Some crop parameters were also measured such as plant height, plant population, fresh and dry weights of plant, grain yield, total biomass and harvest index. Land preparation total costs and sowing costs for the different treatments were also investigated. The results revealed that the disc plow (DP) plus light disc harrowing and leveling recorded the highest fuel consumption rate for the two seasons (31.2 L/ha and 30.52 L/ha), highest plant population in the second season (436.56 plants/m2), highest land preparation total costs (12777.8 SD/ha) and highest grain yield costs (3758.2 SD/ton).The disc plow (DP) treatment recorded the lowest field capacity for the two seasons (0.238 and 0.24) respectively . The moldboard plow (MP) plus light disc harrowing and leveling registered the highest field efficiency in the two seasons (71.83% and 71.81%), highest land preparation costs in SD/hr (5109.57 SD/hr), while the same treatment reported the lowest plant population (381.33 plant/m2) in the second season. The heavy disc harrow(HDH) indicated the highest slippage (%) in the two seasons (9.1% and 8.8%) highest fuel consumption rate in L/hr in the two seasons (9.0 L/hr and 9.72 L/hr), while it showed the lowest field efficiency in the second season (88.9%). No significant differences between the effect of sowing methods on the total biomass were observed, but there were significant differences between tillage systems at 5% level. The highest total biomass obtained by both the heavy disc harrowing (HDH) and zero tillage (9.16 Ton/ha), while the lowest value registered by the light disc harrowing (LDH) (7.74 Ton/ha). No significant differences between the effect of tillage systems on plant height, fresh weight, dry weight and grain yield in (Ton/ha) in the two seasons, whereas there were significant differences at 5% level for plant population in the second season. Highly significant differences at 1% level were observed between sowing methods effect on plant population per m2. The manual broadcasting with the cultivator (CU) method recorded the highest plant population/m2 (471.17 plants/m2), highest total sowing costs in SD/ha and SD/hr giving (3652.2 SD/ha) and (2081.78 SD/hr) respectively. No significant differences between both tillage systems and sowing methods effect on grain yield in ton/ha were observed, but the method of manual broadcasting plus light disc harrow (LDH) recorded the highest grain yield in the two seasons, while the seed drill (SD) registered the lowest values in the two seasons. The seed drill (SD) also resulted in the lowest plant population per m2 in thesecond season (358.17 plants/m2), lowest total sowing costs in SD/ha and SD/hr recording (2740.93 SD/ha) and (1740.49 SD/hr). The highest harvest index (%) registered by the manual broadcasting plus (LDH) (39.79%), followed by the seed drilling machine (SD) (39.58%) then the manual broadcasting plus the cultivator (CU) (37.82%
