Abstract

The use of land without a good management lead to land destruction and environmental damage. Prevention should  be done by soil conservation. The objective of this research was to estimate the level of soil erosion in the upstream of watershed area of Wai Illa by using a survey method for field observations and USLE (Universal Soil Loos Equation) method to predict the amount of eroded soil. The results showed that the existing land use in areas of research was mixed farms, and scrub with a low level of soil damage on land L433 unit1 and high slopes on the land slopes L533 unit 4. It was predicted that actual annual erosion ranged from 16.524 t/ha up to 315.659 t/ha.

Abstract

This study was conducted in Waelo Village, Waeapo Subdistrict, Buru District, with the objectives to determine N fertilizer application timing to increase rice yield and to understand the response of two rice varieties commonly grown in Waeapo. The experimental method used in this study was a Randomized Complete Block Design, with several fertilization treatments (NPK, NK,NP, PK and control), and rice varieties (Membramo and Mekongga), and with three replications. The results showed that administration of N fertilizer (NP, NK, NPK) gave significant effects on plant height, leaf color, full grain number per panicle, 1000 grain weight, dry grain yield, soil N content and leaf N content;  meanwhile it did not affect soil reaction (pH). A low rice yield was obtained in the treatment without N fertilizer, with 2.50 kg dry grain yield per plot and PK treatment with 2.78 kg  dry grain yield per plot.
