(Stellenbosch : Stellenbosch University, 2021-03)ENGLISH ABSTRACT: Wheat (Triticum aestivum) is the main cereal crop being planted in the Western Cape of South Africa and is also accounts for over 40% of the world’s cereal. Wheat can be grown under a variety of environmental ... -
Physical and allelopathic effects of crop residue on wheat, barley and canola production
(Stellenbosch : Stellenbosch UniversityStellenbosch : Stellenbosch University, 2021-03)ENGLISH ABSTRACT: Retention of crop residue has many benefits such as moisture conservation, improvement of soil health and reduction in soil erosion. Residue retention together with no-tillage and crop diversification ... -
Liming strategies for barley and canola production under no-tillage.
(Stellenbosch : Stellenbosch University, 2021-03)ENGLISH ABSTRACT: The slow movement of lime in soil combined with no-tillage practices that restricts the incorporation of surface broadcast lime deeper into the soil has led to an increase in soil acid stratification ... -
