The experiment was conducted for crop seasons 2000-01 and 2001-02 in experimental farm of seed and plant improvement institute (SPII) in Karaj to compare effects of different planting methods of Reform (traditional), Hamedan Machine Barzegar (HMB, Conventional) and Rolling (Recently grain drill) in seeding rates of 80, 110, 140, 170 and 200 kg ha-1 in bread wheat cv. Pishtaz. The experimental design was RCBD in split-plot arrangement with three replicates. What made different between the used methods was their homogeneity in planting seeds in soil achieving better stand establishment and yield. This homogeneity was at least in Reform seeder because of making furrows after planting seeds in leveled land. While this homogeneity fulfilled in the best way through using Rolling method achieving maximum grain and straw yield. Results showed that two major yield components of spike No. m-2 and kernel No. m-2 were the most effective parameters reaching yield potential of the studied cultivar. Due to the significant interaction of the studied factors the best seeding rates for the planting methods were 140 kg ha-1 for Reform and 110 kg ha-1 for HMB and Rolling seeders showing seed use reduction of 30 kg ha-1. Based on the results of economic analysis, the Rolling method and seeding rate of 110 kg ha-1 had the highest net income and the lowest cost comparing other treatments. So the rolling grain drill and seeding rate of 110 kg ha-1 was the best treatment. The mean production cost and net income of this treatment was $1268 and $597 ha-1, respectively. |
