Significant
difference among guar cultivars has also been
reported by Vahidy and Yousufzai (1999) and Singh
et al. (2006). Interaction between nitrogen levels and
cultivars for plant height was also significant. All
cultivars differed significantly at all nitrogen levels.
The cultivar cluster bean 2/1produced shortest plants
and BR-99 tallest plants at all nitrogen levels.
The stem diameter was not affected significantly by
the nitrogen levels and it ranged between 0.84 to 0.88
cm. However, the results are not in line with those of
Suzuki et al. (1991) who reported an increase in stem
diameter with nitrogen application. The contradictory
results might have been due to differences in fertility
status of soil or genetic make up of the varieties. All
cultivars have statistically similar diameter. The
maximum (0.88 cm) and minimum (0.84 cm) stem
diameter was recorded for cultivars BR-99 and 2/1,
respectively. The interaction between nitrogen levels
and cultivars was not significant.
The number of branches per plant were increased
