Potato is one of the most important agricultural products that has great nutritional and industrial value. Potato seed tubers are usually used for growing this crop, but separating the seed tubers from the edible ones is tedious, time consuming and costly process. Therefore, a rotating potato sorting machine was designed, developed and evaluated in this research. This machine was able to sort potato tubers according to their size. Effects of sieves slope angle and rotational speed on the tubers mechanical damage, sorting accuracy and capacity of designed machine were evaluated. The test was conducted in the factorial experiment format with three replications based on a completely randomized experimental design. Three levels of sieves slope angle (5, 10 and...

This study was conducted to investigate some moisture-dependent physical and aerodynamic properties of garlic cloves (Allium Sativum L.). A completely randomized design (CRD) with five replications was chosen for the experimental layout. The data were analyzed by SAS program version 9.1 and means comparison were done by Duncan’s multiple range test (DMRT). Regression analysis was used to determine the relationship between physical and aerodynamic properties, and their moisture contents. The average length, width, thickness, geometric and arithmetic mean diameter of garlic cloves were 32.0, 21.8, 20.9, 24.4 and 24.9, respectively. The average of the surface area, projected area, one thousand kernel mass, volume and bulk density of garlic cloves increased...

In this study a vacuum seed metering system was designed and developed based on physical and aerodynamic properties of kenaf seed (Hibiscus cannabinus L.). The kenaf vacuum seed metering system was evaluated in the laboratory using kenaf seeds. For laboratory tests, a completely randomized design (CRD) with three replications was chosen. The data were analyzed by SAS program version 9.1 and means separation test were done using Duncan’s multiple range test (DMRT). Based on this study, the most suitable opening diameter and opening angle for planting kenaf seed are 2.5 mm and 120o respectively with having the minimum miss and multiple indices with having optimum quality of feed index.

Selection of fertilization method and fertilizer application rate on corn yield

Abstract: A field experiment was carried out on the silty clay soil of Lack-Lack agricultural research field during two years to select the most suitable fertilization method (fertilizer broadcasting, fertilizer pouring in the furrow, fertilizer banding placement in one side and both sides of seedling) and application rate (30, 60 and 90 kg of net nitrogen from source of urea fertilizer/ha) on corn yield and yield components in Hamedan province in Iran. Corn yield components evaluated were plant height, corn height, percentage of corncob, thousand-kernel mass and net yield. A factorial experiment with 12 treatments (four methods × three levels) was replicated three times in 36 test plots. By analysis of variance and comparison of treatment means using...
