For Indonesia lies in the equator, Indonesia has practically had two seasons only, dry and wet seasons. Indonesia has the best seasons to plant palm oil.
But in last decade, the climates cannot be predictable. The predictions of the El Nino did not happen. The other natural symptom, such as, the increasing temperature once happenned in Indonesia in 1997 and the last one happenned in 2005.
It is rumored that the extream temperature will happen in the middle of 2014. For the plantation businessmen, especially the farmers, they should know the effects of the last drought made by El Nino.
According to Suyatno Reza in his book, Seri Budidaya Kelapa Sawit, the climate conditions play important role to influence the productions of palm oil.
But it should be noticed too, each region in Indonesia has different climate. Though the climate influences, the land can still be controlled in a certain levels by making technology to make good productions.
Suyatno noted, palm oil plantations need rain about 2.000 – 2.500 mm per yar and the rain happens in every single month without no draught in one month.
But what happen if the draught happens in a very long time? According to Udlin Lubis (1985), the drought season could influence the vegetative growth and it can be put into four levels or stadia.
In the I stadia, within water deficit 200 – 300 mm, the symptom can be seen by three to four midribs will be close. In the II stadia, within water deficit 300 – 400 mm, four to five midribs will close.
In III stadia, within water deficit 400 – 500 mm, the process of mature fruit will be disturbed, the new flowers and sex differentiation will be too.
