Abstract:
this study was conducted at the demonstration farm of the horticulture Department at the College of Agricultural Studies Sudan University of Science and Technology Shambat Khartoum North sudan four tillage systems were tested selector disc plough followed by disc harrow,scraper and ridger (dpdhsr) chisel plough followed by disc harrow, scraper and ridger (cpdhsr) rotovator only and zero tillage system with direct seeding. The purpose of the study was to determine the most appropriate system of land preparation for radish plant production (raphanus satvus) under Khartoum State Condition
The nutritive value of the plant was measured It was clear that different tillage system had effect on soil parameter and to lesser extent on plant parameters The highest crop production was obtained with the third system where Rotovator when used only The nutritive value analysis showed no significant defferens between different tillage system Randomized complete block(rcb)designe has been used to carry out the experiment the generated data collected from the field and the laborotary was subjected to statistical analysis fur the more of different tillage system upon as some soil physical properties have been studies in three different depths (10cm,20cm,30cm) the tillage system have similar effect on plant parameters particulevly the mean number plant per hectare , mean number of length of plant root(cm),mean plant weight (gm),mean number of leaves per plant and root diameter
