Growth analysis and photosynthetic rates of cocoa (Theobroma cacao L.) seedlings in relation to varying shade and nutrient regimes

Amelonado and Amelonado X Scavina cocoa seedlings were grown in sand culture under different levels of shade and nutrient supply, and their performance was assessed by analysis of growth and measurement of photosynthetic rates. As shown by previous workers, relative growth rate was found to be maximal for plants grown under medium shade and at the highest nutrient level; net assimilation rates were little affected by shade level even though incident radiation varied over the range 10 to 1. Net photosynthetic rate was highest for leaves developed in full daylight as a result of enhances photosynthetic efficiency. On leaf area basis, net photosynthetic rate was highest in plants maintained at the highest nutrient level. This nutritional difference disappeared when photosynthetic rate was based on chlorophyll content. Amelonado X Scavina was found to grow more vigorously than Amelonado largely as a result of better leaf development in the former; gross photosynthetic rate apparently did not differ between the two types of cocoa.
