Abstract

Considering the importance of the country's rangelands in providing pasture for feeding domestic animals as well as in protecting the soil, it is necessary to find concrete measures on the basis of scientific findings and practical experience. Such measures can help the executive branch as well as the users in better and more efficient use of these resources. It is equally important to utilize suitable machines for mechanizing reclamation of impoverished rangelands. This will increase speed, accuracy and efficiency as well as save time and cost. For this purpose, proper selection of implement is essential. Among the machines used for pasture reclamation are planters. Their proper utilization, particularly use of suitable PRESS WHEELs is very important due to the significant effects that compaction of the soil around the seed has on soil moisture preservation as well as seed germination and growth. In this research, conducted as a split plot experiment based on a completely randomized block design in three replications, the effect of five types of PRESS WHEELs and two initial soil moisture contents (9.1% and 19.3%) on selected plant and soil parameters was studied. Soil texture was heavy clay-loam with some lime. Soil parameters under study included moisture content and bulk density, measured at the following time stages after planting: one week and two months, at 0-15 cm and 15-30 cm depths. Plant parameters included: 1) percent germination of SAINFOIN 2) percent emergence, and 3) plant dry matter. Using analysis of variance and Duncan's multiple range test for comparison of the means, it was determined that at both levels of initial moisture content, using a PRESS WHEEL on the planter is essential. Furthermore, rubber wheels were found to be superior to the metal ones. The lugged press, wheel (type P3) performed better than all the others. The regular rubber wheel (type P4 without lugs) ranks next, having a significant difference with P3in the moist, but not in the dry treatments. Therefore, due to lower production costs, the regular rubber PRESS WHEEL is recommended in dry soil 'conditions. Considering the parameters measured in this study, PRESS WHEELs P1 (boat type), P2 (metallic with a groove), and P5 (metallic without groove) didn't exhibit suitable results.
