WHEN IS THE RIGHT TIME TO HARVEST? (Tips for some commodity)


Harvesting is the act or process of gathering crops or simply it is the removal of the fruits from their mother plant. Some farmers considered the time as a guide for good harvest. Here are some tips on when to harvest some commodity.

- Harvest early in the morning or late in the afternoon when it is cool, especially if cooling facilities are not available except mango and citrus.

- Roses cut in the later part of the afternoon have more carbohydrates since photosynthesis has taken place.

-Sampaguita buds harvested in the afternoon are larger, heavier, and whiter than those harvested in the morning (de la Paz 1986)

- Pechay, mustard and gladiolus break easily when they are turgid, i.e., early in the morning so it's better to let them lose some of their turgidity before harvesting. Harvest during late part of the morning.

- In Chinese cabbage, harvesting at different times of the day, i.e., dawn, mid morning,mid day, mid afternoon and at night did not affect post harvest behaviour and over all quality after storage. (Klieber et al 2002). This was attributed to the protective function of the wrapper leaves that are removed at harvest.

- Sweetcorn is harvested early in the morning to prevent rapid conversion of sugars into starch.

-For mango, the fruits are harvest d mid day between 9:00 am and 3:00 pm. At such time, the sap or the latex flow in mango is slow. When the sap flow is slow, latex stain is less. Latex stain is the discoloration on the peel due to   the corossive action of the latex.
