SUMMARY 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 P 2 0 5 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.
