Fig. 6.8.
The effect of plant density on the yield of bulb onions in varying diameter
grades in 1970, and on yields of total and bulbs < 50 mm diameter in two seasons
in New Zealand that differed in maximum yield attained. The vertical lines within
each histogram bar show the predicted weights of bulbs within each size class,
as calculated using Eqn 6.1, with values of A and B given for 1970, and Eqn 6.3
