Optimal Nutrient Solution and Dose for the Yield of Nuclear Seed Potatoes under Aeroponics

The aeroponic production of certified seed potatoes is a booming alternative for arid and semi-arid areas where fresh water scarce soil-borne diseases nematodes preclude field production. Although widely used in aeroponics, nutrient-solution salinity effects have not been evaluated potatoes. This study aimed to (1) establish the best two nutrient solutions (Otazú vs. modified Furlani) at 20, 50, 100, 150% crop-recommended dose seed-potato production, (2) evaluate growth indexes diagnose plant-N status, (3) prognosis yield nuclear under aeroponics. At 21 days after transplanting, there was significant correlation between nitrate-N petiole-sap test some parameters measured. 4th leaf correlated with indicating that they can be prognosticate final minituber yield. N status potato plants were: area, length, dry weight (Otazú’s), SPAD, area (modified Furlani’s). both had similar nitrogen concentrations, Otazú’s solution 100% recommended lower than Furlani’s produce
