The effect of potassium on growth and yield of strawberry (Fragaria Ananassa (Duchesne ex Weston) Duchesne ex Rozier)

Fragaria ananassa (duchesne ex weston) duchesne ex rozier (strawberry) variety chandler of agriculture research station (ars) baffa,mansehra was evaluated for different growth and yield parameters under five treatments. in this experiment potassium was used in 5 different treatments of 3 replications (t0 = control,t1 = 200 g/6.75m2,t2 = 400 g/6.75m2,t3 = 600 g/6.75m2,t4 = 800 g/6.75m2). the results showed maximum value under t3 (405g/6.75m2) for characteristics like survival percentage (83.54%),plant height (32.05cm),canopy size (13.62cm),crown diameter (2.73cm),number of branches (35.83),number of leaves (67.00),leaf length (5.87cm),root length (3.51cm),total number of fruits (43.93),days to 50% fruiting (233.67),fruit diameter (3.96cm),fruit weight (411.40g). moreover,transplanting date (20th sep,2013) is suitable to get maximum yield of strawberry variety “chandler”. the findings of this experiment showed that great variations in morphological,physical and agronomic traits of strawberry variety and can be utilized to develop high yield and better quality of strawberry. © 2016,pakistan botanical society. all rights reserved.
