Water Table Control Model For Maize Cultivation Aof C Typologi Land On Tidal Lowland Reclaimed Area

Abstract

The research objective is to determine operational model for water management in the field for corn cultivation at several planting times. Area model is conducted at tertiary plot of reclaimed tidal lowland, Telang Jaya Village Primer 8 Delta Telang I Indonesia. Soil analysis is conducted at Soil Chemical, Biological and Fertility Laboratory as well as Soil Physical and Conservation Laboratory, Faculty of Agriculture, Sriwijaya University. There are three treatments of planting times which consisted of the fourth week of April, the second week of June and the first week of July, 2021. Water management model is controlled drainage system in which water surface in tertiary channel is maintained at depth of 50 cm. Results of field experiment showed that maize crop growth showed similar growth quality at each phase. Land with planting period of June and July is still requires water addition by using pump irrigation system, but land with the end of April planting period is not requires pump irrigation. Maize crop production is generally similar with average magnitude of 8.0 ton/hektar.
