(b) List three features of natural pastures.

(c) A piece of land to be used to establish a pasture of Stylosanthes gracilis was surveyed to be circular.

(i) If the radius of the land is 200m and the spacing of the pasture legume is lm by 50cm, what is the population of the legume at one seed per stand?

(ii) If the germination percentage is 75, calculate the expected plant population. (iii) Give two ways in which Stylosanthes gracilis is important in agricultural production.
