Abstract

One main constraint for growing wetland rice in Inceptisol is low soil fertility.  Soil acidity (pH), CEC, C-organic are several indicators used to determine the level of soil fertility. To overcome these kinds of problems, such organic materials as rice husk biochar can be added to the soil in order to modify the soil chemical properties.  This research compared treatments of   different biochar rates with various fineness degrees on soil pH, CEC, C-organic, and  available P.  The research results showed that after incubation for 21 days at room temperature, the best interactionshown by the biochar at the rate of 15 ton ha-1 with 60 mesh particle size can reduce the soil pH by 5.19% from 7.7 to 7.3, increase the soil CECby 32.92% from 16.37 to 22.25 cmol (+) kg-1, improve the soil C-organic by 33.94% from 1.09% to 1.46%, and enhance the soil available phosphor by 277.08% from 12.61 ppm to 47.55 ppm.Keywords: Incubation, Rice HuskBiochar,  and  Soil Chemical Properties.

Abstract

This study aimed to determine the effect of fertilizer and mulch on the intensity attack of S. exigua and the yield of Lembah Palu shallot variety. The research was conducted in Bolu Pountu Jaya, Sigi Village, District of Sigi Biromaru, Sigi Regency, from September to November 2013. The study design was a two-factorial randomized pattern with three replicates for each experimental unit. The first factor was various types of mulch consisted of four treatment without mulch (M0), rice straw mulch (M1), cocoa mulch (M2) and plastic mulch (M3). The second factor was different kinds of fertilizers including liquid organic fertilizer (P1), guano fertilizer (P2) and synthetic fertilizer (P3). There is no significant interaction effect between the type of fertilizers and mulch on the intensity of S. exigua and shallot yields. However, the individual effect of the mulches was significant on reducing the intensity of S. exigua attack and increasing the yield of the shallot. The rice straw mulch reduced the attack intensity of S. exigua by 20.83 %, whereas the cacao mulch increased the yield by 47.61 % compared to the control treatment. Keywords : Fertilizer, Lembah Palu shallot, mulch and Spodoptera exigua.
