Abstract

Rice (Oryza sativa L.) is a staple food for most Indonesian people, but its availability is inadequate. Intensive rice cultivation also cannot solve the problem so the expansion of new paddy fields is usually not optimal. The purpose of this study is to obtain technology for rice cultivation in suboptimal paddy fields by integrating innovative, dynamic and compatible technology components for increased and sustainable production. This research has been carried out with experimental methods on sub-optimal soils in greenhouses and using new types of local rice varieties. Ameliorant compost straw 10 t ha-1 can be used as a type of rice cultivation technology to overcome water stress in sub optimal rice fields. Increasing the water stress period from 60 days to 80 days after planting, the ameliorant in the new rice fields cannot store and supply water to support the growth and yield of new types of local rice.
