efficiency and nitrogen uptake in potato: influence of drought ..

Plant responses to drought stress are very complex as stress itself involves various climatic, soil and agronomic factors, frequently complicated by substantial variation in timing of occurrence, duration and intensity. The general complexity of drought is often aggravated under rainfed conditions in marginal areas by erratic and unpredictable rainfall, and by the occurrence of high temperatures, high levels of solar radiation, and poor soil characteristics. This high variability in the nature of drought stress and an insufficient understanding of its complexity, have made it difficult to identify specific physiological traits required for improved crop performance under drought, consequently limiting plant breeding efforts to enhance crop drought tolerance. It is highly probable that optimal drought-adaptation requires the combination of several morphological, physiological, and phenological processes, which depend on a multitude of genes and varies within each target environment.

Improvement of drought tolerance in potato

In addition to its direct effects on yield, drought can also reduce the potential beneficial effects of improved crop management practices such as fertilizer application or pest and disease management. Given the increasing scarcity of water resources, and competition for them, irrigation is not a practical option for alleviating drought in most of the rainfed areas. Drought management strategies therefore need to focus on maximizing extraction of available soil moisture and the efficiency of its use in crop establishment, growth, biomass and grain yield. However, agronomic and genetic options that do not involve external inputs of irrigation can only partially alleviate drought effects, because .
