Title: Comparison of Tillage Systems and Sowing Methods for Wheat Production in the Low Land of the Northern State (Sudan
Author: Alhag, Hassan Mohamed Ahmed
Abstract: A field experiment was calculated in two successive seasons (200/01 and 2001/02), it’s investigative the effect of the some tillage system and sowing methods on wheat production in the lowland of he Northern State, Dongla province. The treatment consisted of five tillage systems, namely disc ploughing plus light disc harrowing plus levelling, mold board ploughing plus light disc harrowing plus levelling, cultivator ploughing plus light disc harrowing plus levelling heavy disc harrowing plus levelling and light disc harrowing plus levelling, in addition, to zero tillage as control. Each tillage system included three sowing methods, namely manual broadcasting of seeds plus modified ridging (mg) manual broadcasting of seeds plus light disc harrowing (LDH) and seed drill machine (CD). The experiment treatment were replicated three times in a split- plot design with main plots designated tillage system and sub-plots sowing methods. The mold board recorded the highest slippage (8.3%) and the highest fuel consumption rate (3.26L/hr) and the lowest effective field capacity (0.172 ha/hr), while the highest effective capacity (0.503 ha/hr) was recorded by the light disc harrow implement. The results showed that the disc plough plus harrowing and levelling recorded the highest grain yield, plant population and plant high seasons. The different between treatments were significant 5% level for all crop parameters. Mold board plough plus harrowing plus levelling treatment recorded the highest fuel consumption rate (30.75 L/ha) while the lowest consumption rate (11.72L/ha) recorded by the light disc harrow plus levelling tillage treatment. The soil moisture content (db%) was observed to increase with time and depth. By the end of the reason the lightest soil moisture content (27.46%) was observed by the disc plough tillage treatment at ( 80-100 cm ) soil depth, while the lowest moisture content (25.20%) was recorded by the cultivator plough tillage treatment in the first season, while in the second season the highest moisture content (28.91 %) was recorded by the disc plough tillage treatment at (80-100) cm soil depth while the lowest moisture content (%) (25.8) was recorded by the zero tillage treatment. No significant different were observe for the treatment effect on both season. The highest land preparation total cost (86.571 $/ha) recorded by the mold board plough plus harrowing plus levelling, with the lowest cost value (45.993 $/ha) recorded by the light disc harrowing plus levelling. And the highest grain yield cost (23.91$/ton) recorded by the mold board plough plus levelling. The highest total sowing costs (29.107$/ton) recorded by the mold board plough plus the disc harrowing plus levelling plus sowing manually in the light disc harrowing (LHD) method, which the lowest value (6.442 $/ton) recorded by the zero tillage. The highest average grain yield (4.233 ton /ha) recorded by the disc plough plus light disc harrow plus levelling and sowing manual in the modified ridger (mg) method while the lowest grain yield (1.639 ton /ha) recorded by the seed drill machine treatments.
