“…Yield loss of up to 71%, 30%, 18%, and 58% was observed because of late blight (Phytophthora infestans), powdery scab (Spongospora subterranea), black scurf and stem canker (Rhizoctonia solani) and, early blight (Alternaria solani), respectively (Table 2). Some of the most common bacterial diseases are common scab [16], bacterial wilt [17], and blackleg and soft rot [18]. Recent researchers have reported 24.58% yield loss by common scab (Streptomyces scabies), 34.9% yield loss by bacterial wilt (Ralstonia solanacearum), and 39.57% blackleg and soft rot (Erwinia carotovora) (Table 2).…”

Effect of Drought Stress on Potato Production: A Review

Potato is the third most consumed crop globally after rice and wheat. It is a short-duration crop, versatile in use, suitable for growing in a wide range of environments, and its production is increasing rapidly. The modern potato is considered a drought-sensitive crop, and it is susceptible to yield loss because of drought stress. Unfortunately, drought severity, frequency, and extent have been increasing around the globe because of climate change. Potato drought susceptibility has primarily been attributed to its shallow root system. However, several studies in past decades have suggested that drought susceptibility of potato also depends upon the type, developmental stage, and the morphology of the genotype, and the duration and severity of drought stress. They have been overlooked, and root depth is considered the only significant cause of potato drought susceptibility. This review combines these studies to understand the varying response of potato genotypes. This review also explores the current potato production scenario and the effect of varying degrees of drought stress on potatoes’ growth, development, and yield. In the absence of drought-tolerant genotypes, agronomic practices should be improved to mitigate drought stress. Late maturing cultivars, nutrient management, mulching, and foliar application of plant growth regulators can be used during prolonged droughts. Irrigation at tuber initiation and the tuber bulking stage during early droughts can reduce the adverse effects of drought.

“…The mode of action of Ca against SRP appears to be due to an interaction of Ca ions with cell wall pectin, which strengthens the plant cell walls and results in higher resistance to pectinolytic enzymes released by SRP that act to degrade the cell wall (White and Broadley 2003;Barras et al 1994). Ca fertilization is known to reduce soft rot caused by SRP in Chinese cabbage (da Silva Felix et al 2017;Park 1969), in bean (Platero and Tejerina 1976), in chicory (Schöber and Vermeulen 1999) and in potato (Ngadze et al 2014;McGuire and Kelman 1984;Lambert 1991;Ngadze 2018b). However, field trials in Scotland by McGuire and Kelman (1984) revealed that bacterial soft rot caused by P. atrosepticum is negatively correlated with Ca concentration in tubers, and Mantsebo et al (2014) came to the same conclusions for P. brasiliense after field trials planted in Zimbabwe.…”

“…Nevertheless, no significant difference in blackleg incidence was observed 15 weeks after planting. A more recent study using calcium nitrate as an amendment revealed that a supply of 250 kg/ha (19% Ca) allowed an average reduction of 20% blackleg symptoms, with a maximum of 50% (Ngadze 2018a). The corresponding experiments were carried out with seed tubers inoculated with a mixture of P. atrosepticum, P. brasiliense and D. dadantii.…”
