The experiments on crop geometry and nitrogen requirements of lemongrass were conducted atResearch Farm, Department of Agronomy, Punjab Agricultural University, Ludhiana during 2007-08 to 2009-10 on loamy sand soil low in organic carbon and available nitrogen but medium inavailable phosphorus and potassium. In experiment I, five treatments of different combinations ofrow and plant spacing 60 × 60 cm2, 60 × 45 cm2, 60 × 30 cm2, 45 × 45 cm2 and 45 × 30 cm2) were testedin RBD with four replications. In Experiment II, four levels of nitrogen (0, 50, 100 and 150 kg/ha)were tested in RBD with three replications. The pooled data revealed that the highest herb and oilyield was produced in 60 × 30 cm spacing which was statistically at par with 45 × 30 cm, 45 × 45 cm,60 × 30 cm, 60 × 45 cm spacing and significantly higher than 60 × 60 cm. The application of 100 kgN/ha produced the maximum herb and oil yield which was significantly better than 50 kg N/haand control (without nitrogen) and it was statistically similar to 150 kg N/ha. Different spacing andnitrogen levels did not show significant effects on the oil content in the herb.
