Effect of Some Tillage Operations on Sorghum Yield in Rainfed Agriculture (Al Gedarif State, Sudan)

Abstract

This research had been conducted at mechanized rainfed agriculture sector, Gedarif State (SUDAN), in the period (2007 – 2008) for two consecutive seasons. The objective of this research aimed to study the effect of different tillage treatments on the productivity of Sorghum. The experiment has been set in the complete randomized block design with four treatments applied, with four replicates. The treatments represented by chisel plough, disc harrow, wide-level disc and zero tillage .The study included effect of different tillage treatments on Sorghum production components: plant height, number of tillers and productivity. The disc harrow treatment registered the highest readings for plant length (97.75 cm, 90.2 cm) for the two seasons respectively, whereas zero tillage treatment gave the lowest reading for the plant length (86cm) in the first season, while the chisel plough treatment recorded the lowest readings in the second season .The wide-level disc treatment reading 90.75 cm, 86.5 in the two season consecutively.
