The effect of crop load, position of the fruit on the shoots and vigour of the shoots on yield and quality of Annona atemoya × A. squamosa hybrid ‘Arka Sahan’ was investigated in India over two years. The trees were hand-pollinated and thinned to 20, 40, 60, 80 or 100 fruit after fruit set. Information was collected on total and marketable yield, yield efficiency, average fruit fresh weight, peel weight, the number of seeds per 100 g of pulp, pulp content in the fruit, total soluble solids (TSS) and total titratable acidity. In other experiments, fruit were harvested from weak, medium or vigrous shoots, or from basal, middle or apical nodes. Total yield increased up to 60 or 80 fruit per tree and marketable yield increased up to 60 fruit per tree. Average fruit weight and peel weight increased as cropping increased. These results suggest that optimum productivity and quality is associated with 60 fruit per tree or 0.17 to 0.19 kg cm2 trunk-cross sectional area. The quality of the fruit in different positions on the shoots or on the different types of shoots was highly variable and generally not affected by the various treatments.
