Summary

A field experiment was conducted for 2 years during the crop seasons of 1980–2 to study the effect of diverse plant spacings and rates of nitrogen application on the yields of herb and essential oil of palmarosa (Cymbopogon martini Stapf. var. motia). The results indicated that at closer plant spacings of 30 × 30 cm (110 000 plants/ha) and 45 × 30 cm (74000 plants/ha), palmarosa responded to higher amounts of N fertilizer (240 kg N/ha/year). It was suggested that a plant spacing of 30 × 30 and 45 × 30 cm and application of 240 kg N/ha/year result in high essential oil yield of palmarosa.
