Evaluation of Potato Varieties Grown in Hydroponics for Phosphorus Use Efficiency

Global phosphate mineral resources are nonrenewable and inevitably depleting. Exploiting elite varieties has become imperative for the efficient use of phosphorus (P) sustainable crop production. Three potato were hydroponically evaluated P mobilization, uptake, utilization efficiencies at different levels sources during 28 d seedling growth. ‘Harley Blackwell’, ‘La Chipper’, ‘Red LaSoda’ selected from a previous study grown in modified Hoagland solution, with concentrations soluble high as NaH2PO4 (10 mg L−1 P), low (1 286 sparingly tri-calcium [TCP, Ca3(PO4)2] 2286 CaSO4. Blackwell’ Chipper’ had significantly greater biomass than or TCP treatments. In low-P stress, efficiency was that other two varieties. more mobilization compared to cultivars. The holistic score analysis indicated most P-efficient while least P-efficient. results this show solution successful screening
