12 Dec nutrient deficiency in potato plants
In addition, potassium deficiency affects the ability of the plant to access and process other nutrients properly. Biochem J 299:277–284. inspecting potatoes. Fertilisation practices in potato production are discussed. Besides dry matter, starch content and specific gravity, K can affect the content of reducing sugars, which are precursors for acrylamide formation in processed potato products (Panique et al. In this review, the importance of balanced fertilisation for potato yield formation and yield security is addressed by taking advantage of the results of field trials and existing literature. margins. https://doi.org/10.1080/01904167.2014.983124, Stark JC, Westermann DT, Hopkins B (2004) Nutrient management guidelines for Russet Burbank potatoes. Moreover, under broadcast application higher P fertiliser rates are often needed: this increases the risk of runoff losses. forward roll and scorched margins; defoliation of oldest leaves. https://doi.org/10.1007/BF02871962, De Kok LJ, Castro A, Koralewska A, Durenkamp M, Posthumus FS, Stuiver C, Yang L, Stulen I (2005) Pathways of plant sulfur uptake and metabolism: an overview. 2014).

During this growth period, nitrogen favours stem growth. 1998). 1997; Gerendás et al. 156, phosphorus deficiency). A major part of Ca is present in bound form. https://doi.org/10.1111/1365-3040.ep11614586, Jenkins PD, Ali H (2000) Phosphate supply and progeny tuber numbers in potato crops. Hence, delivery to the plant roots is mainly enabled by mass flow (Zhang and George 2002). Besides, a simple visual diagnosis might be a helpful tool to identify N deficiency during growth. For instance, compared to early maturity types, later maturity types can profit more from additional available N, especially later in the growing season (Tiemens-Hulscher et al. Here, soil mineral N (NO3− and NH4+) is extracted from soil layers from 0 to 60 cm soil depth prior to planting (Vos 2009). Based on the emerging challenges in modern agriculture, De Wit (1992) suggested that the laws developed by Liebig, Mitscherlich and Liebscher could be used as particular alternatives in one dynamic model. 2015). S can be translocated within the plant both via phloem and xylem, although translocation via the phloem from older to younger leaves can be restricted. The most Ca is distributed in the above-ground parts of the plant (Ozgen et al. However, while countries with a high-input agriculture, such as the USA, France and Germany, can reach average potato yields of more than 45 t ha−1 (Table 1), the average yields of most other countries are considerably lower leading to average potato yields of 20 t ha−1 worldwide (Table 1). PO Box 50949-00200, City Square Nairobi – Kenya. He concluded that both agriculture and environment should focus towards the minimum of production resources that are necessary for maximum use of other resources (De Wit 1992). Therefore, the proper amount of application and the placement of nutrients is important. complete mineral nutrient, tubers normal. P serves various functions in plant metabolism. First, there are the main roots, transporting water mainly to the aboveground parts of the plant. External quality traits include tuber size and shape as well as resistance against mechanical stress during and after harvest. A critical review of all essential nutrients in potato growth is beyond the scope of this review. and scorched leaflets. Nutrient Deficiencies Nutrient deficiencies occur when plants are unable to take up the essential nutrients they need for growth at any point in the growing season. (1997) suggest that soil K values below 104 mg K kg−1 for sandy soils and below the range of 100 to 125 mg K kg−1 for medium-textured soils, such as silty loams, are critical. = 50% K2O (water-soluble) and 45% SO3 (water soluble). 1990).

Too little or too much of any one nutrient can cause problems. Springer, Dordrecht, pp 639–642. Therefore, unlike most other crops, potatoes have an unusually high range of utilisation possibilities, which makes their production even more attractive. 1994b). The most important roles of the macronutrients nitrogen, phosphorous, potassium, magnesium, calcium and sulphur in the plant and their importance for yield formation in potato are reviewed. Nucleic Acids Res 11:2665–2679. Not all plant problems are caused by insects or diseases. Email: email@example.com. "One, a potato plant with potassium deficiency has a poor root system, so the plants cannot normally take up other nutrients. Plants need to absorb what you feed them.

While useful as a starting point to diagnosing production problems, keep in mind that multiple nutrition disorders often occur simultaneously. 2019a). https://doi.org/10.1093/oxfordjournals.pcp.a076335, Leigh R, Wyn Jones R (1984) A hypothesis relating critical potassium concentrations for growth to the distribution and functions of this ion in the plant cell. Nutrient disorders limit crop production in all types of soil around the world. Although liming can usually increase potato yields, people often refrain from liming these soils as soils with higher pH values could favour the development of common scab (Streptomyces spp.) Similar to the application practices for N, there exist also for P the possibility for an in-season fertiliser application beside pre-planting P fertiliser application. https://doi.org/10.1002/jpln.201600340, Jansen MAK (2002) Ultraviolet-B radiation effects on plants: induction of morphogenic responses. https://doi.org/10.1007/BF01088079, Errebhi M, Rosen CJ, Gupta SC, Birong DE (1998) Potato yield response and nitrate leaching as influenced by nitrogen management.

Using Hydroponics to Understand the Earth's Life Processes Although Koch et al. Moreover, Marabel belongs to the early maturity group and Désirée to the medium-early maturity group (FPVO 2018). Potato Res. Growth normal; foliage healthy green color. However, the starch concentrations (% in DW) did not show significant reductions upon K deficiency. 3. In young plants, potassium deficiency is indicated when plant leaves are dark green to bluish in color, and usually glossy in appearance. Organic. 2012) and fungal infections, such as early blight (Alternari solani), silver scurf (Helminthosporium solani) and black scurf (Rhizoctonia solani), as well as Fusarium and Verticillium wilt (Rich 1983).

Physiol Plant 116:423–429. J Plant Nutr Soil Sci 179:733–745. In general, independent of the K source that is supplied (either as K2SO4 or KCl), the yield can be increased by increasing K fertilisation (Panique et al. Lettuce. https://doi.org/10.1111/nph.12087, White PJ, Broadley MR (2003) Calcium in plants. Correspondence to Effect of combined K and Mg fertilisation on yield of potato. The International Plant Nutrition Institute (IPNI), J.R.

J Agric Res 47:167–178, Mengel K, Kirkby E (2001) Principles of plant nutrition. Proceedings of the American Society for Horticultural Science 36, 544-549. The extremes of a nutrient deficiency can be easily determined, but. Because nitrogen is a mobile nutrient in the plant, symptoms begin on the older, lower leaves and progress up the plant if the deficiency persists. 2008). In this review, the importance of balanced fertilisation for potato yield formation and yield security is addressed by taking advantage of the results of field trials and existing literature. Potato. Based on this fundamental knowledge, a potato grower may decide the accurate choice of type, time and amount of fertiliser application. The International Plant Nutrition Institute (IPNI), J.R.

J Plant Nutr Soil Sci 152:135–141. Approximately 58–70% of the total N is taken up during this development stage (Ojala et al. At the same time, there are very specific K transporters which ensure, depending on the K concentration in the soil solution, K uptake at low (HATS = High Affinity Transport System) as well as at high K concentrations (LATS = Low Affinity Transport System) (Britto and Kronzucker 2008). Critical nutrient concentrations for deficiency and toxicity, and the adequate concentration ranges for sweet potato, measured in the 7th to 9th open leaf blades from … With regard to placement, a primary distinction can be made between broadcast and band P fertiliser application. 2015). 2016). Sometimes, an unhealthy plant is suffering from a nutrient deficiency or overload, meaning too much of any one nutrient. Moreover, in view of comparably low soil Mg status, the high K supply further reduced Mg uptake by the potato plants. 2016).

Along with K, Mg serves as a cation in similar physiological processes, for example, in the regulation of the cation–anion balance and as an osmotically active ion in the turgor regulation of cells (Marschner 2012). As compared to K, this reduces the availability of Mg to the roots (Deng et al. Under K deficiency, there can be an accumulation of sucrose in leaves, which has been found in potato plants (Koch et al. acid soil. Crop Sci 39:1544–1551.

In: Haverkort AJ, MacKerron DKL (eds) Potato ecology and modelling of crops under conditions limiting growth. The Art of Healing Ourselves " With sulfur depletion, the upper and older leaves are first affected, while nitrogen problems show up on the younger leaves first. When there are too much of the nutrients, they show symptoms of being unhealthy. (1994a, 1994b) showed a decrease in dry matter production in the roots compared to the shoots of bean plants grown in a nutrient solution under conditions of Mg deficiency, while Hermans et al. Nitrogen deficiency in plants can occur when organic matter with high carbon content, such as sawdust, is added to soil. Usually, chloroses are equally distributed over the whole leaf. It seems as if plants are able to overcome Mg depletion in the later growth stages without any severe impact on root growth or morphology when they had earlier been sufficiently supplied with Mg. 2013; Ahmed et al.
