Peanuts are harvested in two stages. The first stage involves the complete removal of the plants from the soil and the second stage is the drying and separation of the peanut pod from the plant. This study was conducted in Moghan, in 2020. The purposes of this study were to estimate cost and benefit of harvesting methods and to determine profitability indices with using a special peanut traction combine. The experiment was performed based on a split plot design in the form of randomized complete blocks with four replications. The research was based on whether the imported traction combine is more economical compared to other common methods of peanut harvesting? Three harvest methods in the second stage include: b1- combine harvesting b2 - harvesting with a thresher behind the tractor, b3 - manual harvesting. To find out if the assumption proved, we used partial budgeting technique including net present value (NPV), economic and non-economic test for substitution of harvesters and marginal rate of return (MRR). The results showed that the MRR rate of replacing the application of traction combine with other treatments in the average area harvest conditions is higher than 41.83%. According to the results, it was found that net profit in traction combine harvesting compared to thresher behind the tractor and manual method had a profitability of 6.07 and 8.82 percent, and a cost reduction of 4.86 and 23.43 percent, respectively.

In recent years, the cultivation of peanuts has increased in the Moghan region, which currently has an annual planting area of more than 6,000 hectares. This study was performed to select the most suitable planter with the desired planting pattern. The experimental design was carried out in a randomized complete block design with six treatments and four replications, in 2020. Treatments include a1 and a2, planting with a distance between rows (ridges) of 75 cm and between plants (12 and 17 cm), respectively, a3 and a4, twine planting with a distance between rows of 75 cm and between plants (22 and 28 cm), respectively, and a5 and a6 , planting was one row with a distance between rows of 50 cm and between plants (25 and 30 cm), respectively. Parameters measured were uniformity of seed depth, planter field capacity, seed germination, mechanical damage to seed, yield and yield components of peanut. The results indicated that planter type was significant at the 1% probability level for uniformity of seed lateral, planter field capacity and seed germination and at the 5% probability level for Number of pods per plant and peanut yield. However, there was no significant effect on 100-seed weight and mechanical damage to seeds. It was found that planting with a two-row pneumatic planter obtains the best results in terms of green percentage uniformity, seed cross distribution and yield. The highest uniformity of horizontal distribution and germination of seeds were 79.25% and 95%, respectively. The maximum yield in this tow row planter was 4995.30 kg.ha-1 with a distance between plants of 28cm. Therefore, compared to planting a row with a distance between the ridges of 75 cm, the average yield was increase 400 kg.ha-1.
