Effects of phosphorus and potassium fertilizers on the yield contributing characters and yield of sub-tropical strawberry

Abstract

Abstract : Proper nutrient management is the key in fruit production for achieving higher yield and quality fruits. To evaluate the yield potential of tropical strawberry under different doses of phosphorus (P) and potassium (K) fertilization, the experiment was conducted at the research farm of the Department of Horticulture, Bangabandhu Sheikh Mujibur Rahman Agricultural University, Gazipur. The treatments were designed in seven combined doses of phosphorus and potassium fertilizers viz. T, - P0 K100 kg/ha, T2 - P25 It,,,, kg/ha, T3 - P50 K|00 kg/ha, T„ - P„ K100 kg/ha, T5 - P50 K„ kg/ha, T6 - P50 KJ0 kg/ha and T7 - P50 KI50 kg/ha. The results showed that the treatment T3(P50K100 kg/ha) was the best considering yield and yield contributing attributes of strawberry. The highest number of flowers (9.67) and fruits (9.67) per plant, the heaviest (18.37 g) and largest (1895.1 mm2) fruit and maximum fruit yield (16.17 t/ha) were also obtained from the treatment T3. The combined application of 50 kg/ha phosphorus and 100 kg/ha potassium could be used to obtain higher yield for successful production of strawberry.
