AbstractA field experiment was conducted during 1999–2003 to ascertain the performance of five lemongrass accessions, collected from naturally growing habitat of Northeast India. Morphological characters of the accessions were studied and yields of oil and citral were recorded. The gas chromatographic analysis of the oil recorded eight major compounds constituting 90% of the oil. Oil (0.55 –1.03%) and citral (78.0–95.0%) was found to be the maximum in RLJ-TC-10 through out the year. Citral content of RLJ-TC-1 and RLJ-TC-9 was found to be at per with that of RLJ-TC-10, however oil content was found to be low. Citral content was comparatively low in RLJ-TC-4 (78.1%) amongst the accessions. Results were compared with the standard cultivar OD-19 that was grown parallel with the other accessions. Seasonal variation was found to be very effective on the yield of oil and its constituents. Citral percentage was maximum in winter season (November-December) and minimum during the rainy season (July-August). Oil was found to be the highest (1.03%) during pre monsoon (March-June) and onset of monsoon. Considering the yield of oil and citral, accession RLJ-TC-10 was found to be the superior amongst the five accessions even better than OD-19 and can be considered for commercial exploitation particularly under the agro-climatic conditions of North Eastern India |
