Strengthening the Agroclimatology Analysis against Local Wisdom Paddy Planting Time at Coastal Area in Indonesia

Abstract

Coastal paddy fields are areas that have distinctive land characteristics that affected local wisdom in the paddy cropping calendar. The local wisdom of the coastal paddy planting schedule is a cultural heritage that is aimed to accelerate the planting time, to minimize the risk, to adapt with the optimum planting time or to implement the local paddy varieties. This paper discusses the agro-climatology analysis to provide scientific strengthening to the local wisdom of the coastal paddy cropping calendar in Banyuasin, Kapuas, Tanah Laut, and Kutai Kertanegara Regency. The results of the analysis illustrate that the local wisdom of paddy planting time in Banyuasin is carried out before the beginning of the rainy season to avoid damage when salty water runoff occurs through rob at the critical paddy growth phase. The paddy planting time in Kapuas is done at the peak of the rainy season to avoid acidity poisoning during paddy growth. The paddy planting time in Tanah Laut is carried out before the start of the rainy season to provide the planting season duration with uses the long-lived local varieties. The paddy planting time in Kutai Kertanegara is done at the peak of the rainy season to avoid high salinity levels that have the potential to interfere with paddy growth and production. The information of the rainy season prediction and agro-climatology analysis provides an important role in determining the planting schedule according to local wisdom and rainfall condition in the four districts.
