A multiplex polymerase chain reaction (PCR) assay for simultaneous, fast and reliable detection of the main soft rot and blackleg potato pathogens in Europe has been developed. It utilises three pairs of primers and enables detection of three groups of pectinolytic bacteria frequently found in potato, namely: Pectobacterium atrosepticum, Pectobacterium carotovorum subsp. carotovorum together wi...

A four-year rotation is desirable for potatoes. Proper rotation of crops is one necessary practice for avoiding the holding over of potato diseases in the soil. For potato wilt control at least a four-year rotation should be used. The one shown here makes use of corn, grain, clover, and potatoes. The best basic crop rotation for Western Oregon is grain, clover seed, clover hay, and a cultivated...

Potato (Solanum tuberosum L.) varieties, viz. Kufri Lauvkar (early maturing), Gaurav and Jyoti (medium maturing) were examined during the years 2018–19 2019–20 for seed size tubers production with 3 dates of haulm killing, 70, 80, 90 days after planting under West-Central Indian conditions at ICAR-Central Research Institute, Regional Station Gwalior, Madhya Pradesh. Haulm killing 80 (15.05 t/ha...

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...

Abstract This research aims to study the effect of number harvest rows under two digging depths and cultivars on quality harvesting potatoes (damage losses). The experiment was factorial, using a randomised complete block design with split-split plot three replications for each treatment. types were placed in main plot, type digger secondary split depth plot. results showed no significant diffe...

The process of digging potatoes is characterized by high energy costs due to the interaction potato digger's plowshares with tuber-bearing soil layer. study aims substantiate parameters lattice plowshare. In proposed digger, plowshare made latticed and equipped oscillating rods. This digger has a mechanism for transmitting torque experiments were carried out using special laboratory-field insta...

Sweet potato is grown extensively from tropical to temperate regions and is an important food crop worldwide. In this study, we established detection methods for 17 major sweet potato viruses using single and multiplex RT-PCR assays. To investigate the current incidence of viral diseases, we collected 154 samples of various sweet potato cultivars showing virus-like symptoms from 40 fields in 10...

In this paper, we consider the problems of multipacket batch and balanced routing on d-dimensional (constant d 2) torus and mesh-connected processor arrays. We present new \hot-potato" routing algorithms which achieve the best known average-case and worst-case time bounds for both problems on all such networks. In particular, our results include the following: 1. Algorithms that route almost al...
