Pratylenchus penetrans suppressed the tuber yields of potato cultivars 'Katahdin', 'Kennebec', and 'Superior', but did not affect yields of 'Russet Burbank'. In comparison with noninfested controls, all initial nematode densities (P(i)) of P. penetrans (P(i) = 38, 81, 164, 211/ 100 cm(3) of soil) suppressed yields of Superior; a moderate P(i) (81/100 cm(3) soil) suppressed yields of Kennebec; a...

The yield and quality of field crops are affected by abiotic stresses such as water deficit, which can negatively impact crop growth, productivity, quality. However, nanotechnology holds great promise for increasing yield, maintaining quality, thus mitigating stresses. Therefore, the current study was conducted to examine influences 0, 50, 100 mg L?1 zinc oxide (ZnO) nanoparticles 25, 50 silico...

The dearth of fertile ‘virgin’ land and inaccessibility to standard chemical fertilizers, coupled with low tuber yields has made cassava cultivation unprofitable in parts of traditional cassava zone of West Africa. Field experiments were conducted at Ajibode and Alabata villages located in Ibadan (derived savanna zone), Nigeria to evaluate cassava (Manihot esculenta Crantz) root yield response ...

Under optimum environmental conditions, tuberization in potato (Solanum tuberosum) is activated by signals that either function in the leaf or arise in this organ and move down into stolon tips to induce tuber formation. Three major signals have been identified: CYCLING DOF FACTOR1 (StCDF1) for earliness and StBEL5 mRNA and SELF-PRUNING6A (StSP6A) protein as mobile signals originating in the le...

The performance of seed tubers harvested from potato plants grown from sprout cutting, stem cutting and conventional seed tubers against PVY and PLRV were investigated. Sprout cutting, stem cutting and conventional seed tubers of variety Diamant were planted and second and third generation seed tubers were harvested. The least incidence of PVY and PLRV was recorded when seed tubers from sprout ...

Potatoes (tubers of Solanum tuberosum) are grown and eaten in more countries than any other crop, and in the global economy they are the fourth most important crop after the three cereals maize, rice, and wheat. Therefore, research into potato tuber initiation and development, which enables our understanding and possible manipulation of these processes, is of great relevance. In addition to imp...

Vegetative propagation of potato allows the dissemination of viruses that can cause drastic drops in tuber yield. Potato virus Y (PVY) is one of the most important viruses of potato due to the non-persistent mode of transmission through vector insects. Genetic resistance is the recommended control measure since the chemical control of vector insects is not effective. This study aimed to identif...
