Nutrient status of carnation leaves in different planting dates, pinching methods and nitrogen levels was estimated. Maximum leaf N (2.176%), P (0.259%) and K (3.651%) was recorded in October planted crop. Leaf NPK content was higher (2.168, 0.259 and 3.628%, respectively) in single pinch method as compared to pinch and a half method. Application of nitrogen 1500 ppm resulted in maximum NPK content of leaves (2.241, 0.266 and 3.668%, respectively). A positive linear relationship was found between N content of leaves and days taken to bud formation, days taken to flowering, flower size, plant height, stem length, stem strength and flower yield m−1. The relationship between N content of leaves and calyx splitting was negative.
