Effect of different levels of nitrogen and phosphorus on growth and yield of strawberry (Fragaria ananassa Duch.) cv. Chandler

A field experiment was carried out at Department of Horticulture, Sam Higginbottom Institute of Agriculture, Technology and Science, Allahabad, India during 2012-13. The experiment was laid out in randomized block design (4x3 factorial) with 12 treatments in thrice replications on different levels of nitrogen and phosphorus. The treatments included 4 levels of nitrogen (0, 100, 150 and 200) and 3 levels of phosphorus (0, 80 and 100). The results revealed that maximum plant height (21.43cm), number of leaves (20.73), plant spread (28.46cm) and petiole length (11.55cm) were recorded in T11 (200 kg N/ha + 100 kg P/ha). But the minimum days taken to first flower appearance (54.93), maximum number of flowers (6.53), fruits (5.07) and yield (281.54g/plant) were obtained by T8 (150 kg N/ha + 100 kg P/ha).
