Response of Petunia hybrida to varying levels of nitrogen, phosphorus and potassium was studied at SKUAST-K, Shalimar, to find out the optimum levels of these nutrients for quality seed production of petunia. Nitrogen and phosphorus significantly improved the vegetative as well as seed yield and yield attributing characters. Application of 30 g/N/m2 alone gave the maximum seed yield (26.81 g/m2) followed by 30 g phosphorus (22.79 g/m2) alone. However, potassium alone did not affect seed yield. A combined application of 30 g nitrogen, 20 g phosphorus and 10 g potassium proved superior over individual application and yielded 29.65 g seed/m2.
