Effect of nitrogen, phosphorus and potassium on growth and yield of strawberry (Fragaria x ananassa duch.) cv. sweet charlie

The present study was aimed to investigate the impact of major nutrients N, P and K on plant height, plant spread, number of leaves, petiole length and fruit yield of strawberry cv. Sweet Charlie. The experiment was carried out at Research Farm, Horticulture Department, AAI-DU, Allahabad (India) during winter season 2006–07. The application of 100 kg N + 80 kg K/ha resulted in maximum growth and yield improvement in strawberry followed by 100 kg N treatment and 80 kg P + 80 kg K/ha treatment. The study revealed that strawberry crop requires optimum NPK to harness maximum yield.
