Other claims from this paper (9)

Association Flower number in marigold dropped from 641 in July to 129 after pruning.
Intervention effect Pruned marigold rows had lower average flower diameter (3.00 to 3.16 cm) than non-pruned rows.
Association Rhyolite-treated marigold rows gave the highest fresh flower weight in June (12.42 g/row).
Intervention effect In July, flocculant gave the highest marigold yield (488.6 g), compared with 362 g in the control.
Observation In August, poultry manure rows produced 467.25 g of marigold flowers.
Observation In August, flocculant-treated marigold rows yielded 487.33 g.
Association Flocculant gave the highest cumulative marigold yield over the year (980.76 g per row).
