Organic agricultural techniques are utilized globally to protect our environment and prevent health issues resulting from pesticides and hazardous chemicals. In this regard, studies were conducted using six different organic amendments on strawberry (Fragaria ananassa Duch.) cv. Chandler which included T = planting 1 media -1 (soil + silt + farm yard manure); T = planting media + 400 mgl humic 2 -1 acid; T = planting media + 200 g kg leaf manure; T = planting media + 200 3 4 -1 -1 g kg vermicompost; T = planting media + 200 g kg plant fertilizer and T = 5 6 -1 planting media + 200 g kg bio-compost during 2011-12 at PMAS-Arid Agriculture University, Rawalpindi. Treatment T (soil + silt + FYM) induced 1 positive influence on plant height (15.21 cm), canopy spread (20.37 cm), crown diameter (1.47 cm), fresh weight of plant (10.71 g), number of runners per plant (2), total number of flowers (58), total number of fruits (42), fruit size (3.04 cm), fruit weight per berry (8.82 g) while T (soil + silt + 4 -1 200 g kg vermicompost) improved fresh leaf weight (0.92 g), number of 2 leaves (6.67), leaf area (43.07 cm ) and days required for first bloom (96.67). Leaf manure based treatment (T3 ) enhanced root length (20.11 cm), T4 improved quality parameters like total solid soluble (TSS) (8.88) and ascorbic acid contents (64 mg) while T improved total sugar contents in 1 fruits (6.82%). Hence farm yard manure(FYM) and vermicompost based organic amendments enhanced vegetative growth and improved quality of strawberry fruits.
