potato is one of the most productive crops in agriculture and is a valuable food source in developing countries. mycorrhizal fungi involve a symbiosis with most of crop roots and leads to improve the crops growth and yield. in order to investigate the effect of mycorrhiza fungi species on yield of potato cultivars a factorial experiment was arranged in a randomized complete block design with ei...

introduction: water scarcity is one of the primary problems in arid and semi-arid regions such as iran. in these regions, increasing water productivity in agriculture sector is inevitable. water productivity can be increased using the drip irrigation method and application of irrigation strategies such as deficit irrigation. potato is the major crop in dehgolan plain. researches have shown that...

The response of potato, Solanum tuberosum L., tuber yield to stem injury by European corn borer, Ostrinia nubilalis (Hübner), larvae was investigated in the Mid-Atlantic region of the United States for 3 yr. This response was described for 'Superior', 'Atlantic', and 'Snowden' potato, which are early-season, midseason, and late-season maturing cultivars, respectively. To model the yield/injury ...

A field experiment was conducted in 2009 and 2010 at the Teaching and Research Farm of the University of Agriculture, Makurdi, Benue State, Nigeria. The purpose of the experiment was to investigate the yield and yield components of newly introduced sweet potato varieties under various planting patterns with pigeonpea. Neither fertilizer nor insecticide was applied. This was done in accordance w...

Potato is a strategic crop in Tunisia but is susceptible to many pests and diseases. Nematodes of the genera Meloidogyne and Globodera are important pests that cause yield losses and depreciation of tuber quality. A trial was carried out in a plot where the soil was naturally infested with M. javanica and G. pallida. Three soil treatments were tested and compared. Soil solarization (SS) and inc...
