GENERAL The yield of cardamoms varies considerably with the age of the plantation the nature of the soil and weather conditions. [...] A gradient of infestation is evident in the direction of the long axis of the area infestation being severest in plots at the centre and least in the end plots. [...] The numbers of damped-off seedlings in plots subjected to the various treatments would accordingly provide an estimate of the efficacy of the treatments. [...] As the beds were very thickly sown it was felt that if the assumption that within any bed the percentage emergence per unit area was approximately the same for the various treatments was valid the areas of soil surface exposed by the removal of damped-off seedlings would provide a more reliable and a more easily recorded estimate of the intensity of the disease than a count of damped-off seedli [...] The first appearance of damping-off in the nurseries followed closely on the beginning of the rains.
