Abstract
Reduced tillage is one of the options to combat land degradation problems. The study aims to examine the impacts of tillage practices on selected soil physicochemical properties, soil loss, and maize yield and yield components. Four treatments—zero, twice, and strip tillage—as well as farmers' practices, were set up in a randomized complete block design with five replications. Then, soil moisture, soil loss, and yield and yield components of maize data were collected. The findings show that, when compared to conventional tillage, conservation tillage improves soil moisture and decreases soil loss during and after crop development. The study found that implementing reduced, or zero tillage practices resulted in higher maize yields and long-term economic benefits for farmers compared to conventional and strip tillage practices. In addition, the current research demonstrated that, in comparison to strip tillage and conventional tillage, adopting reduced tillage and zero tillage increased maize yield and yield components with greater long-term economic benefits to farmers. The current findings also showed that adopting reduced tillage and zero tillage boosted maize yield and yield components, with higher economic benefits to farmers in the long run as compared to strip tillage and conventional tillage. Although zero tillage attributed to less grain yield, it resulted in higher economic benefits to farmers and saved 44.84% of soil loss relative to conventional tillage. The outcome of the economic evaluation unequivocally demonstrated that reduced tillage is the best approach, but zero tillage, strip tillage, and reduced tillage are all superior and advised for farmers. Hence, farmers can use either zero tillage or reduced tillage, depending on their investment capital. But to get considerable changes in soil and water balances, other soil physicochemical properties, and crop yield. Similar studies must be carried out on permanent field plots for longer than 2 years in the future.
