Abstract

Field experiments were carried out in 2018 and 2019 cropping seasons to determine the productivity of sesame varieties as influenced by tillage practices in Makurdi, southern guinea savanna, and Potiskum, Sudan savanna agro-ecological zones of Nigeria. Treatments consisted of three varieties of sesame (Jigida, NCRIBEN-01M, and NCRIBEN-032) and three levels of tillage practices (zero tillage, flatbeds, and ridges). Treatments were laid out in a randomized complete block design (RCBD) and replicated thrice. Prior to planting, surface (0-15 cm) soil samples were collected from eight points and bulked; post-harvest composite soil samples were also collected on the basis of treatments. All soil samples were analyzed using standard analytical procedures. The data generated from the study were subjected to Analysis of Variance (ANOVA) using Genstat Release 10.3 DE after which significant means were separated using Least Significant Difference (LSD) at 5% level of probability. Results indicated that improved varieties performed better than the local varieties in terms of yield. Crop performance was higher in Potiskum than Makurdi. Ridges produced higher yields followed by flatbeds and then zero tillage at Makurdi and Potiskum. The effects of variety on soil properties did not differ significantly however, the improved varieties left lower essential nutrients in the soil. Zero tillage retained higher nutrients and organic matter in the soil while ridges gave lower values for essential nutrients and organic matter. For sustainable sesame production in both locations, it can be recommended that sesame should be grown on ridges. For conservation/retention of essential nutrients and organic matter in the soil, zero tillage is recommended for both locations.
