Title: Evaluation Of Some Land Preparation And Sowing Methods For Wheat Production In Northern State (Dongola Area) - Sudan
Author: Ahmed, Mergani Salih Seid
Abstract: A field experiment was carried out at dongle agricultural research station farm, North State, during the seasons 2001/2002 and 2002/2003 to investigate the effect of some tillage systems and sowing methods on wheat production and cost of land preparation and sowing. The tillage treatments consisted of disc ploughing, heavy disc harrowing and on-tillage. Two sowing methods used were manual broadcasting with ridging and seed drill sowing. The field measurements were, soil moisture content, infiltration rate, plant population, grain and biological yield and harvest index. Some machinery measurements were also carried out (effective field capacity, field efficiency and wheel slippage and fuel consumption). Land preparation and sowing costs of different treatments were also calculated. The results revealed that disc plough recorded the highest average soil moisture content (21.4%) and infiltration rate (30.6 cm/hr). During the two seasons disc ploudhing treatment recorded the highest average plant population (481 plants/m2), grain yield (4.1 ton/ha), total biomass (13.63 ton/ha) and highest harvest index (30.7%). The differences between the effects of most treatments used were significant at 5% level. Seed drill recorded higher plant population (490 plants/m2) and total biomass (12.66 ton/ha) while manual broadcasting and ridging recorded higher grain yield (3.63 ton/ha) and harvest index (29.5%). The highest wheel slippage (8.9%) and fuel consumption (15.1 L/ha) was given by the disc plough implement where as the highest field efficiency (70.4%) and effective field capacity (0.75 ha/hr) recorded by the seed drill machine. The highest land preparation cost was recorded by the heavy disc harrowing (17569.1 SD/ha), while manual broadcasting and ridging incurred the highest sowing cost (5299/ha). The highest cost of land preparation with sowing was given by the heavy disc harrowing and manual broadcasting (22868.7 SD/ha and 6370.1 SD/ton of crop yield). The lowest cost were given by zero tillage with seed drill (2254.1 SD/ha, 870.3 SD/ton). The highest net benefit was obtained from the disc plowing tillage treatment with seed drill sowing (224629 SD/ha) and lowest benefits obtained from zero tillage with seed drill sowing (146671 SD/ha), but zero tillage with seed drill sowing gave the highest benefits in SD/ton of crop yield (56629).
