EFFECTS OF NITROGEN. PHOSPHORUS, POTASSIUM AND SULPHUR ON GROWTH, YIELD AND NUTRIENT CONTENT OF STRAWBERRY (Fragaria ananassa)

Abstract

The experiment was conducted at Ilorticulture Research Centre. Ciazipur. Bangladesh. during the period of November 2011 to April 2012 to study the eRects of nitrogen. phosphorus, potassituli and sulphur on gro'vtli, yield and nutrient content of strawberry. The experiment was laid out in Randomized Complete Block Design (RCBD). There were 4 levels Of different nutrients. viz. 0.90. 115 and 140 kg N ha' 0. 20,40 and 60 kg P ha; 0.85. 110 and 135 kg K liaH 0. 15. 25 and 35 kg S ha". Iliere was a positive impact of each fertilizer combinations on yield. yield parameters and nutrient contents of BARI Strawberry I except control treatment, the highest values of plant height (25.60 cm): number of leaves (21.66). flowers (125.33). fruits (12.35). destwyed fruits (I I ). fruit weight (2 I 5. 10 g) plant and fruit length (4.1 6 cm). fruit (liameter (3.4 tern), individual fruit weight (1 7.85 -,)and fruit ield (1 I .50 t ha") were ft'und in treatment of 115-40-I 10-25 kg ha" NPKS. respectively. Anion2 thc t'erti lizers. the single effect of nitrogen (I I 5 kg lia' ). phosphorus (40 kg ha'). potassium (110 kg ha) and sulphur (25 kg ha ') gave maximum growth and yield of strawberry. The highest concentration of N. P. K and S were found in shoot and fruit of strawberry when N-P-K-S fircilizers were used 140-60-135-35 kg ha'. respectively.
