Soil Ameliorant in Post Tin Mining Land of Bangka Island for Pepper Growth

Abstract

__ Pepper is one of the spices plant and its production countinous decrease caused by converting of the planting areas to tin-mining areas. One of the effort that could be done was the usage of sub-optimal land which has low fertility. The research was aimed to study the effect of soil ameliorant application for early growth of pepper plant in the sand tailing area and obtain the proper ameliorant. The research was carried from February to May 2017 in post tin mining land of PT Timah, Dwi Makmur Village, District of Merawang, Bangka Island. The research was arranged in a Randomized Block Design (RBD) single factor dan three replications. The factor used was soil ameliorant combination consisted of seven level i.e. NPK fertilizer, arbuscular mycorrhiza fungi (AMF), biofertilizer, NPK + biofertilizer, NPK + AMF, AMF + organic fertilizer, and NPK + AMF + organic fertilizer. The soil ameliorant applications showed significant effect to plant height, leaves number, segment number, stem diameter, leaf area and chlorophyll content. Complete combination (NPK + AMF + biofertilizer) was the best ameliorant to pepper growth in sand tailing areapost tin minning.

“…At the end of the study, Table 2 shows how many plants were still alive. Research in nursery shows a high survival rate (>90%) due to the provision of soil ameliorant that include biochar and other organic soil ameliorant [51][52][53][54][55]. However, the survival percentage in this trial was not particularly encouraging, despite being in the favorable category (50% -75%) [56].…”
