Abstract

The study of “Water Management Technology Against Rice Productivity in New wetland Openings of Iron Poisoning Rice” was carried out in Betara District, West Tanjung Jabung Regency from April to October 2018. The research used a randomized block design (RBD) with four replications. The treatment consisted of four intervals of providing irrigation water, namely; (CI) Continuous irrigation, (DWI1) Dry wet irrigation (DWI) 5 day intervals from 1 week to 7 weeks after planting (WAP), (DWI2) DWI with 7 days interval from 1 week to 7 WAP, and (DWI3) DWI 7 days interval from 1 WAP to 65 days after planting (DAP) and inundation 15 days before harvest (DBH). Fertilizer recommendations based on soil nutrient status as a result of analysis with the Swamp Soil Test Kit (SSTK), namely 1.0 tonnes / ha lime, 75 kg ha-1 Urea (basic fertilizer) then based on LCC, 150 kg ha-1 SP 36 (given entirely at planting time) and 125 kg ha-1 KCl (1/3 part at planting, 1/3 part at 3-4 WAP and 1/3 part at plant age 6-7 WAP. Result showed the water supply interval significantly affects the growth and production of rice, the highest yield is obtained with a 7 day water supply interval from 1 to 7 WAP, with rice production 4,29 tonnes ha-1, whereas with the provision of water from 1 WAP until just before harvest, the rice production was 2.06 tonnes ha-1.

Highlights

Increasing population from year to year has implications for the need for food which is increasing
Conversion of productive paddy fields to non-agricultural land is unavoidable, especially in Java. This encourages the government to look for potential land that has not been used optimally, one of the efforts is by expanding the planting area and printing new rice fields which are mostly directed at sub-optimal lands outside Java [1,2]

Summary

Introduction

Increasing population from year to year has implications for the need for food which is increasing. Conversion of productive paddy fields to non-agricultural land is unavoidable, especially in Java. This encourages the government to look for potential land that has not been used optimally, one of the efforts is by expanding the planting area and printing new rice fields which are mostly directed at sub-optimal lands outside Java [1,2].
