The study looked at different ways of farming on sloping land to see how they affect soil erosion and wheat yield. They tested reduced tillage, no-tillage, subsoiling, and conventional tillage over 6 years. No-tillage and subsoiling were best for keeping soil and water on the land. Subsoiling gave the highest wheat yields, about 9.4% more than conventional tillage. No-tillage also increased yields, except in very rainy years. Reduced tillage didn't make much difference in soil loss or yield. Subsoiling seems like a good choice for farmers in the area to improve soil and water conservation.
