在雨季（2010/11年）在两个地点进行了实地试验（Khorelabeid和Kaba）进行调查，以调查耕作对高粱生长和产量的影响耕作实践处理包括免耕、15和25 cm深度的耕作和两种耕作模式，即：采用随机完全区组设计（RBCD），将处理随机安排，重复三次。结果表明，不同耕作处理对本研究所测定的大部分参数都有显著影响，即增加耕作深度可增加株高、节间长、剑叶长、穗长、穗粒数、穗粒重、穗粒重、穗重、穗粒数、穗粒重和产量（t/ha）均以25 cm深的头茬方式最高，而免耕处理的籽粒产量和产量构成因素均较低。
A field experiment was carried out under rainy season (2010/11),at two locations (Khorelabeid and Kaba) in Sheikan locality, North Kordofan State, Sudan to investigate the effects of the tillage on growth and yield of grain sorghum(Sorghum bicolor L.Moench).The tillage practices treatments consist of no tillage,tillage at depth 15 and 25 cm and two tillage patterns namely:headland and continuous patterns,using chisel plough.Treatments were randomly arranged in a randomized complete block design (RBCD) with three replications. The results showed that tillage treatments had significant effect on most of the parameters measured in this study.In this respect, it was observed that increased tillage depth increased plant height, length of internode.Length of flag leaf, panicle length, number of seeds per panicle,panicle seed weight, grain yield (Kg/ha) and harvest index.The tillage depth of 25cm with head land pattern had the highest number of grains per panicle, panicle grain weight and grain yield (t/ha), while the no tillage treatment had a lesser grain yield and yield ’ s components.
