Evaluates photosynthetic efficiency and productivity in fig trees using potassium silicate and pruning, indicating effective management strategies.

The aim is to assess how potassium silicate application and pruning management influence the productivity of fig trees in semi-arid regions.
Randomized block design with a 5 × 3 factorial scheme
Five potassium silicate doses applied foliarly (0.0%, 0.5%, 1.0%, 1.5%, 2.0%)
Three branch numbers tested (3, 6, and 9) per plant plot
Potassium silicate doses of 0.5%, 1.5%, and 2.0% improved photosynthesis in fig trees.
0.5% dose resulted in a 59.91% increase in productivity and a 49.08% increase in dry matter accumulation.
Optimal results occurred with six productive branches and applications of 0.5% potassium silicate.
