“…The increase in N, P, K and S content of potato tubers due to application of different rates of potassium could be due to the increased uptake by the plant and increased availability of the nutrients, better root growth and increased physiological activity of roots to absorb nutrients. The results are in correspondence with the results of Das and Behara [12] in sweat potato, Sing et al [13] in potato, Hariyappa [14] in onion, Al-Moshileh et al [15] in potato, Bryan et al [16] in potato, Prabhavati et al [17] in chilli, Ahmed et al [18] in faba-bean, Abd El-Latifa et al [19] in potato, Yohana and Carlos [20],Verma and Singh [21] in onion, Mudasir et al [6] in garlic, Mohan et al [22] in potato.…”

Quality and storage attributes are major concern for potato cultivators as well as processors. Therefore an investigation was carried out to study influence of different levels of sulphur and potassium on different quality and storage parameters of potato. The experiment was laid out in Randomized Complete Block Design with three replications of two factors with four levels of each factor. The two factors were S (sulphur) and K (potassium) with four levels as, S0 (control or no sulphur), S1 (20 kg S ha-1), S2 (40 kg S ha-1) and S3 (60 kg S ha-1) where as potassium levels were, K0 (control or no potassium), K1 (100 kg K ha-1), K2 (125 kg K ha-1) and K3 (150 kg K ha-1). Maximum value (1.48 g cc-1) for specific gravity, Soluble solid content (6.31 0Brix), vitamin C (16.58 mg 100 g-1), crude protein content(1.93%) and Dry matter content (23.09%) in tubers were recorded with S3 (60 kg ha-1) , besides significantly lower values of physiological weight loss (17.50%), sprouting (16.93%) and rotting (15.04%) were also recorded with S3 (60 kg ha-1) level followed by S2 (40 kg S ha-1). Significantly maximum values of quality traits like specific gravity (1.79 g cc-1), Soluble solid content (6.92 0Brix), vitamin C (21.62 mg 100 g-1), crude protein content (2.35%), Dry matter content (25.49%) in tubers were recorded with K3 (150 kg K ha-1), further significantly lower values of physiological weight loss (13.89%), sprouting (11.47 %) and rotting loss (9.92%) were recorded with S3 (150 kg K ha-1). Conjugation of 150 kg K ha-1 K+ 60 kg S ha-1 recorded maximum values of quality traits specific gravity (1.80), soluble solid content (7.63 0Brix), vitamin C (22.10 mg 100 g-1), crude protein content (2.49%) and dry matter content (25.92%), however S content of 0.367% was recorded with K3S3(150 kg K + 60 kg S ha-1), besides significantly lower values of physiological weight loss (13.47%), sprouting (10.44%) and rotting loss (5.43%) followed by S3K3 treatment.

“…Organic matter, as well as potassium fertilizers, is essential because the FYM improves the absorption and availability of potassium for potato plants. b) Sulfur Mohan et al (2017), observed the impact of different potassium levels and sources on the potato at Krishi Vigyan Kendra Kandali, Hassan, Bangalore and revealed that the highest growth parameters such as the plant height (49.0), number of branches (2.83), and total dry matter production (6366 kg ha -1 ) recorded with the dose of 75:75:175 kg ha -1 NPK with potassium in the form of biopotassium + sulfur (S) and the number of tubers and the tuber weight were significantly higher due to the application of 75: 75: 175 kg ha -1 NPK with potassium in the source of bio-potassium+ sulfur (4.80 and 560) and was comparable to 75: 75: 175 kg ha -1 NPK with potassium in the form of SOP + sulfur (4.6 and 545). c) Nitrogen Shunka et al (2017), stated the determination of optimal doses of nitrogen and potassium for the production of potato in the highlands of central Ethiopia and observed that potassium levels significantly affected yield parameters as compared to control.…”

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.
