Abstract

This research starting in August to November 2014, which is located in the Porame village,Kinovaro District, Sigi Regency, Central Sulawesi province to the altitude of 235 meters above sea level. The Experimental method used was randomized block design in factorial with three replications. The first factor consisted of M0=unmulched, M1=black-silvered plastic mulch, M2=sawdust mulch and M3=rice straw-mulch, whereas the second factor were four NPK Mutiara dosages; P1=NPK dose 100 kg.ha-1 ,P2=NPK dose 200 kg.ha-1, and NPK dose 300 kg.ha-1. Each treatment was repeated 3 times so that overall there are 48 experimental units. The observed variables were the growth parameter root long ,plant height, tuber diameter, soil moisture content, weed dry weight, and yield (number and weight of chilli). The result showed that application of mulches give significant affect of all growth dan yield parameter, and NPK Mutiara fertilizer dosages were significant effect to root long, plant height , number of fruits per plant, fruit weight per plant, fruit weight per plot, fruit weight per hectare and soil moisture content. The best mulch and dose for chilli crops in upland area was black silvered plastic mulch whith NPK Mutiara fertilizer dose 300 kg/ha of 7.32 ton.ha-1

Abstract

This research aims to determine the factors that cause erosion, measure the level and how to overcome the dangers of erosion in the Bolapapu watershed. This research was conducted in the Bolapapu watershed which is located in the middle of the Miu sub-watershed and is located in Kulawi District, Sigi Regency, Central Sulawesi Province. The results of the research show that in various forms of land use using plant management methods (C) and conservation techniques, namely soil management (P), there are several things that can be concluded: (1) changes in plant management factors on each land unit can prevent the level of danger of erosion and can increase land productivity; (2) conservation measures, namely soil management (P), can change the physical shape of the length and slope of the slope and inhibit the rate of runoff; (3) in land rehabilitation efforts using plant and soil management methods in relation to erosivity which can change the physical form of erodibility; (4) land rehabilitation planning in the Bolapapu watershed can not only reduce the level of erosion hazard or increase land productivity, but can improve the economic conditions of the community through plant management. economically valuable actions through conservation techniques.
