Abstract
This research aims to study and analyze the effect of the no-tillage method and seeding rate on wheat yield in Khorramabad Region, Iran. Moreover, data was evaluated, and the split-plot design in form of randomized complete blocks was used with three replicates. The main factor includes three levels of different tillage methods: 1) moldboard plow + disc (2 times) + drill-deep furrow planting (the region’s conventional method); 2) disk (2 times) + deep furrow; and 3) no-tillage seeding (direct seeding). The secondary factor, however, was the seeding rate at three levels (150, 180, and 220 kg/ha). The results indicated that the highest germination rates belong to the minimum tillage and conventional tillage treatments. In terms of germination rate, Treatment 1 performed better than the minimum tillage treatments with 150, 180 and 220 kg/ha; however, this difference was not statistically significant. This could be due to loose soil allowing roots to penetrate further. Additionally, according to the results, it could be concluded that different tillage methods produce tangible and significant effects on wheat yield. The mean comparison showed that Treatment 2 had the best performance, in terms of yield, with 5540 kg/ha followed by Treatment 1 (conventional) and Treatment 3 with 4560 and 3780 kg/ha, respectively. Moreover, the maximum harvest index belonged to Treatment 2 and the best seeding rate to achieve the highest harvest index was 180 kg/ha.
