Grain drill performance can be affected by creating clods during seedbed preparation in dry soil conditions. To increase performance of grain drill in dry soil conditions need to design the new opener for grain drills. This study has been carried out for the economic evaluation of the suitable tillage method for planting by grain drill equipped with a bent leg furrow opener and their effect on the yield of irrigated wheat. This study was a randomized complete block experimental design with four treatments and four replications. Treatments were seeding winter wheat by a grain drill with bent leg furrow opener in three tillage practices of no-tillage (T1), reduced tillage (T2), and conventional tillage (T3). Seeding wheat by conventional grain drill in the conventionally tilled plots was also used as control treatment (T4). In order to investigate the economic effects of tillage and planting methods by the bent leg grain drill on wheat yield, the income and cost of treatments were measured, and using the marginal net profit analysis method, the economic rate of return on investment of each method. The results of showed that the most suitable treatment from the economic point of view is the bent leg tillage treatment + planting with a grain drill equipped with a bent leg furrow opener. The findings showed that the bent leg tillage + the bent leg grain drill, as a new technology, has the potential to increase crop yield and can increase the farmer's net profit.

Today, farmers are looking for solutions to increase production and income. One of these solutions is the supplyink off-season crops and horticultural products. Considering the high level of okra production and consumption in Khuzestan province, this study was conducted with the aim of evaluating the economic systems of this product. In this area, okra is cultivated in three ways: okra planted under plastic, mulch and open field. Required data was collected using face-to-face questionnaire from 120 okra growers. The highest amount of net income (287.44 million Rials per hectare) was obtained in okra planted under plastic, plastic mulch (87.06) and open field (61.98) were in the next priorities respectively. The highest amount of benefit-cost ratio (3.7) was obtained in okra planted under plastic, open field (2.3) and plastic mulch (2.1) were in the next priorities respectively. The highest amount of production cost (103 million Rials per hectare) was obtained in in okra planted under plastic, plastic mulch (78.5) and open field (48.7) were in the next priorities respectively. The highest amount of mechanization cost index (10.6%) was obtained in open field, plastic mulch (6.8%) and okra planted under plastic (4.6%) were in the next priorities respectively.
