seed loss at harvesting time is one of the factors reducing seed yield in at farms. this study was carried out within a research farm in karaj to evaluate and select a proper pinto bean line for mechanized harvesting at two moisture contents during harvesting and their effect on seed yield and yield loss among three lines of pinto bean. the experiment was split-plot based on randomized complete...

wheat is one of the most important food staff in consumption pattern of each country. more than 50 percent of energy is provided by bread in the developing countries. the aim of this study was measuring wheat losses during pre-harvest and harvest stages in chaharmahal and bakhtiari province of iran in year 2013. wheat losses at harvest stages were measured to wheat varieties in 2 levels of omid...

In the process of rice harvesting, passability track combine harvester is often limited by state soil. Meanwhile, wet and soft paddy soil compacted under rolling harvesting machinery, which also affects function ecological environment. Therefore, relationship between physical mechanical properties was studied in this paper. addition, compaction from a on field with without stubble studied. The ...

colza (canola) is a crop with high rate of grain loss during harvesting. at harvest, semi-dried grains of canola’s pods are either opened or dropped due to mechanical impacts. therefore, lots of grains drop before entering combine head. another obstacle to successful harvest of canola is that ripe grain's pods are twisted together. this results in heavy grain loss at dividers of combine pi...
