The present study was undertaken to observe the potentiality of seed germination of wild vetiver (Vetiueria zizanioides L. Nash) over a five-month period (from mid July to mid November 2003) along with other phenological features. The total length (mean plus minus SD) of vetiver culms was 206.32 plus minus 42.43 cm. The root and shoot lengths (mean plus minus SD) of 8 weeks old seedlings were 3.93 plus minus 0.25 cm and 4.79 plus minus 1.29 cm, respectively. The fitted regression line equation for the root and shoot length was found as Y = 0.074 + 1.20 X, where X and Y are root and shoot length, respectively. The calculated value of `t' (41.355) and correlation coefficient, `r' (0.99) substantiates that there is a highly positively significant relationship between root and shoot length at 0.01% level of significance. The overall percentage of seed germination (mean plus minus SD) was 41.48 plus minus 5.63. However, further trial with the germi nated seedlings is necessary to explore its viable potentiality at the field level.
