    Abstract

    The impact of El Nino has been predicted until November 2015, this condition causes most of the rice fields in the swampy areas experiencing drought. Generally under normal conditions of rice cultivation in this area does not have a water shortage problem. Field studies was conducted in the area of swampy areas in Musi II Palembang. Rice cultivation was done at June. The results show a decline in rice production which in normal conditions reaches 5-6 tonnes / ha but currently only produce an average 2.5-3.0 tonnes / ha. A decline in rice production is due to water stress in the generative period. Field studies showed farmers do not make the process of adaptation of water management technologies. Drainege system is still open so that the water is so easily lost towards the swampy lowland in the mid and later. Adaptation technology with water retention systems and improving drainage channels would increase water status in the soil. It has been tested on swamp reclaimed areas at Kumpeh Muara Jambi. The drainage system is controlled by containment models using stoplog gate with a height of 50 cm surveillance, to maintain the ground water level in the land at optimum level under 50-100 cm below the soil surface. Maize production obtained is 5.5 tons / ha, at harvest time (October, 5 2015) the groundwater is at a depth of -140 cm below the soil surface.
