Influence of potassium on the productivity and quality of potato: A Review

Abstract

Potato ranks one of the most important food crops after rice, wheat, and other field crops. A healthy potato crop removes about 1.7 to 2.3 quintals of potassium ha-1, illustrating that the potassium requirement for potatoes is much higher than that of grains. Being a shallow root crop, the effectiveness of using potassium fertilizers on potatoes varies from 50 to 60 percent. Potassium nutrition plays an important role in increasing the potato yield, either due to the formation of large tubers or the increase in the number of tubers per plant. Among the integrated nutrient management in potatoes, farmyard manure improves the absorption and availability of potassium for potato plants. Potassium protects against frost and drought stress in plants and reduces the incidence of diseases or pests. Potassium availability also decreases the concentration of reducing sugar and improves the colour and quality of potato chips. Potassium sulfate improves potato quality better than sources of potassium chloride.

Response of Bacillus megaterium and Bacillus mucilaginosus Strains on Yield and Quality of Soybean

“…Increased N content due to seed inoculation with bio-inoculants and foliar spray resulted in higher protein content because of their beneficial role in enhancing N content in seed. Similar, findings have also been reported by [19] and [20] in soybean.…”

Seasonal Changes in Photosynthate Partitioning in High Yielding Sweet Potato Varieties under Varied K Nutrition Levels

“…Genotypes which can grow and yield well in soils low in available K are potassium efficient. Tuber crops have a high requirement for potassium compared with cereals, as the content of potassium in the harvested roots is high (Singh et al 2020). There is still 1 Seasonal Changes in Photosynthate Partitioning in High Yielding Sweet Potato Varieties under Varied K Nutrition Levels finite data on growth and potassium assimilation in sweet potato in response to varying potassium supply levels over time and the computation of such characteristics is necessary to screen for K efficient varieties (Rengel and Damon, 2008).…”
