The probability of spreading cysts of Globodera rostochiensis on farming equipment and potato tubers was investigated in naturally infested field plots. The number of cysts recovered from soil that adhered to equipment differed significantly between different pieces of equipment. These differences were related to initial nematode density and, in most cases, to the volume of soil that adhered to...

disk plows are one of the most important tillage tools. two way (reversible) disk plows can perform continues plowing. so they can save time and costs and hence improve overall efficiency. in this study, a “two-way” disk plow was designed based on a λ-formed straight-line, four-bar linkage (daniel mechanism). this design contains disk and rear wheel reversing mechanism, stabilization mechanism ...

Potatoes are one of the most responsive crops for grooming techniques since in period from seedlings before closing rows easily suppressed by weeds that take away nutrients, water, light it. The factor causes high harm to potatoes is weed. By absorbing a large number nutrients and moisture soil, inhibit growth development plants, reducing their potential productivity. purpose study was establis...
