| description | Addressing poor seed quality is pivotal for increased potato yields in Kenya. For this to be realized there is a need for nutrient optimization in the hydroponic system. The objective of this study was to examine the effects of nutrient stock solution concentrations on the quality of minitubers produced under a hydroponic system. Two greenhouse experiments were set up at Egerton University, Kenya in 2022. The treatments included three nutrient solution concentrations: 75% (N75), 100% (N100) and 125% (N125) and four potato varieties (Wanjiku, Unica, Shangi and Nyota) grown in a cocopeat substrate hydroponic system. The results indicated that the application of N125 produced minitubers that had significantly higher specific gravity, dry matter, starch, ash and sugar content. Crude protein and phosphorus did not differ significantly with the application of varying nutrient concentrations. The varieties did not differ significantly in the quality parameters except for total sugars where Unica was significantly different from Nyota and Wanjiku while Shangi did not differ from all varieties. Therefore, it will be advisable to apply 125% of the ADC-Molo recommended nutrient stock formulation which should be considered as an effective method of increasing minitubers quality under a hydroponic system. |
