Abstract
Field experiment was conducted to evaluate the influence of application of nitrogenphosphorus fertilizer and harvesting time on growth, yield, oil content and physiochemical properties of M. spicata L. oil. Eight treatment consists of different N-P fertilizer dose and four harvesting period were used for the study. Maximum plant height was found at N2P2 treatment. N2P3 fertilizer treatment produced highest herb yield. The oil content of M. spicata L. was maximum at 130 day harvesting period. The oil refractive index was also enhanced with increasing harvesting time. In case of interaction effect between different level of nitrogen-phosphorus and harvesting time showed highest oil concentration at N2P2 treatment within 130 days harvesting time. Where as the optical rotation, acid value and density of oil was remain more or less same during the whole experiment period. Key words: M. spicata, Nitrogen-phosphorus, Fertilizer, Harvest time, Optical rotation, Acid value and Oil content. DOI: 10.3329.bjsir.v43i1.856 Bangladesh J. Sci. Ind. Res. 43(1), 47-54, 2008
