Abstract

The rice field harvested area in West Kalimantan decreases each year around 0.96 kw/ha from 2013. The decline in rice production is due to climate change. The objective of this study to determine the potential and constraints of developing Planting Calendar (KATAM) to anticipate the impact of climate change in West Kalimantan. The study was conduct in Tujuh Belas Sub District, Bengkayang District, West Kalimantan from January to December 2018. This study was performed using demonstration plot by comparing the existing farming system, KATAM, and introduced technology. The analysis used a randomized block design (RBD), where each treatment was repeated 3 times. The result showed that the vegetative parameters for the height of the existing treatment were higher than other treatments (76.40 cm). For the parameters of the number of tillers, KATAM and Introduction pattern had a large number of tillers, namely around 18 per plant. The treatment with KATAM pattern also had a high number of pithy unhulled grains and low unhulled rice (139 and 42 unit/penicle). The weight of 1000 seeds and yield per hectare, the treatment using KATAM pattern had a higher weight and yield (27.07 gr and 5.30 ton / ha).
