Potato is one of the most important tuberous crops. To achieve optimum yield in potato, suitable brand and sufficient and balanced soil nutrients are necessary. In order to study the effects of Zinc, Manganese and Copper on potato yield and leaf and tuber concentrations of Phosphorus and Iron, a factorial pot experiment with 32 treatments was conducted in greenhouse of Soil Science Department, ...
some researches made in the field of agency problem issue, deal with the role of control systems regarding owners and managers. in this research the relationship between the two control mechanisms, namely the voluntary disclosure (external control mechanism) and outside directors (internal control mechanism), which are reductive of agency problems, has been studied. for this reason, a sample ...
Strategies to enhance local adaptation capacity are needed to mitigate climate change impacts and to maintain regional stability of food production. The objectives of this study were to simulate the climate change effects on phenology stages, potato production in the future and to explore the possibilities of employing planting dates and various varieties (Agria, Arinda and Santeh) as mitigatin...

In order to investigate the effect of organic and inorganic nutrient sources on sweet potato tuber yield, we carried out a series of experiments at Hobu, Morobe Province, PNG. In the first experiment, plots were planted with Piper aduncum , Gliricidia sepium and Imperata cylindrica . After one year, these plants were slashed and sweet potato was planted. Sweet potato yield was lowest in plots w...
