Melons are also susceptible to chilling damage, so storage temperatures need to be closely monitored, to improve shelf life.
Too much nitrogen at later stages of growth can spoil fruit quality by increasing the level of blemish on the rind and encouraging fruit rot. Thus, it is important to confirm rates and timing following local trials that take into account the need for high yield, but also good quality fruit.
Poor calcium nutrition results in a wide range of fruit quality problems. The most visible sign of poor calcium nutrition is a collapse during storage. It is followed by a loosening of the seeds in the fruit and in some cases germination of the seeds.
Boron is important in improving calcium mobility. Like calcium, it has a key role to play in maintaining the integrity of the fruit skin.
