The influence of zero-tillage practice on soil, weed control during winter fallow and growth behaviour of sorghum and cotton is discussed in relation to conventional practice. In a year of partial drought when all yields were reduced, zero-tillage gave slightly superior results, but when moisture was adequate it depressed yields by up to 40%. The yields of following crops of wheat and vetch after sorghum, were depressed in the zero-tillage plots by 5-30% in 2 field experiments, compared with conventional practice. CCT.
