Abstract
The impact of potassium fertilization on fruit quality and content of some nutrients of Brown Turky Fig grown in Dirab, Riyadh, King Saud University was studied during the 2015 and 2016 seasons. Results showed that applying K2O at a rate of 400 g per tree followed by an application rate of 200 g per tree increased the fruit weight, fruit volume, and fruit dimensions. Highest total acidity in the first season was observed in fruits from the control trees (no potassium fertilizer added) followed by fruits from trees treated with K2O at rate of 100 g per tree. Application of K2O at a rate of 400 g per tree followed by a rate of 200 g per tree led to higher values of TSS and total sugars in the fruits of both the seasons. It was noted that the K2O when applied at a rate of 400 g per tree increased reducing sugars and moisture content and when applied at a rate of 200 g per tree led to the highest non-reducing sugars in both the seasons. In addition, the results indicated that the N and K contents increased while P content decreased significantly with increasing rate of potassium fertilization in both the seasons. Treatments of K2O at a rate of 100 g per tree led to the highest P content in both the seasons
