Modification of growth, yield and lodging response of lentil to phosphorus by paclobutrazol

A foliar application of paclobutrazol (1 litre a.i. ha“¹) was applied before flowering of lentils grown with different levels of phosphorus (0, 20, 40, 60, 80 and 100 kg P₂0₅ ha”¹). Increasing amounts of P up to 80 kg ha“¹ increased plant height, crop dry matter and grain yields but also increased crop lodging. Paclobutrazol decreased plant height and lodging and increased grain yield. Maximum yields were obtained with a combination of 80 kg P ha”¹ and paclobutrazol.
