Abstract

Increasing green bean production in West Kalimantan can be done through the utilization of marginal red yellow podzolic soils. Constraints of red yellow podzolic soil as a planting medium are having lumpy soil structure, low permeability, poor aeration and drainage, low water holding ability can be improved by adding rice husk charcoal which has the advantage of improving porosity and aeration as well as a binder of nutrients so that they are not easily washed out. This study aims to determine the best dose of husk charcoal for the growth and yield of mung beans on red yellow podzolic red yellow podzolic. The research was carried out in the experimental field of the Faculty of Agriculture, Tanjungpura University, Pontianak. This study used a Completely Randomized Design (CRD) which consisted of 6 treatment levels and 4 replications, each replication consisting of 3 samples so that there were 72 plants. The treatment consisted of a0 = without rice husk, a1 = 5 tonnes/ha , a2 = 10 tonnes/ha, a3 = 15 tonnes/ha, a4 = 20 tonnes/ha and a5 = 25 tonnes/ha. The variables observed in this study were plant height, root volume, plant dry weight, number of pods per plant, seed weight per plant, and weight of 100 seeds. The results showed that the application of rice husk charcoal at a dose of 25 tons/ha gave the best growth and yield of green bean on red yellow podzolic soil.INTISARI Peningkatan produksi kacang hijau di Kalimantan Barat dapat dilakukan melalui pemanfaatan tanah marginal Podsolik Merah Kuning (PMK).

These changes will affect nutrient uptake, growth and yield of garlic. Biochar application  with the right dose needs to be known so that it would be efficient and economical in biochar utilization. The aim of the study was to know the chemical characteristics of peat soil ameliorated with corn cob biochar and to find the effective dose of biochar for growth and yield of garlic.This research was conducted at the experimental field of the Faculty of Agriculture, Tanjungpura University, Pontianak. The experiment used a completely randomized design, consisting of 5 treatments, each treatment consisting of 4 replications. The treatments were: b1 = without biochar; b1 = 50 g/polybag; b2=100g/poly bag; b3= 150 g/polybag and b4= 200 g/polybag. The observed variables ware chemical characteristics of the peat media including pH, organic C, total N, C/N, available P, Base saturation, CEC, Ca, Mg, K, Na, Pb, Cd. Other observations were plant dry weight, tuber dry weight, N, P, K, Pb and Cd content in garlic plant tissue. The results showed that the application of biochar did not cause significant changes in pH, C-Organic and Total N, but the addition of biochar doses tended to further increase the levels of P in the soil. The application of biochar increased the available K and Na levels and soil base saturation, but the Ca and Mg levels, available Ca and Mg levels tended to decrease with increasing doses of biochar. The dry weight of garlic plants increased with increasing doses of biochar. The dose of 200 g of biochar was the most effective for the growth and yield of garlic bulbs on peat soil. Keywords: Garlic, Corncob Biochar, Peat INTISARI           Biochar yang ditambahkan pada media gambut akan mempengaruhi perubahan sifat  kimia tanah seperti  peningkatan pH, C organik, N total, P total, K total, kation-kation basa seperti Ca, Mg, Na, KTK dan Kejenuhan Basa.

Abstract

   Immobilization of Pb in the form of bonds with inorganic compounds can occur with the availability of large amounts of solubilizing phosphate in the rhizosphere. High solubilizing phosphate in the rhizosphere can be an indication of the presence of phosphate solubilizing bacteria that work effectively in the rhizosphere. Exploration, isolation and characterization of these beneficial bacteria need to be carried out, so that strains that are able to grow well in rice growing areas can be propagated as biofertilizers. The purpose of this study was to examine the content of lead (Pb) and the characterization of phosphate solubilizing bacteria in rice planting areas in Sungai Kakap District, Kubu Raya Regency. This study used a field experiment method. Soil samples from the rice plant rhizosphere and rice plant samples were analyzed in the laboratory according to the variables that had been determined. The results of this study indicate that the available phosphate content in paddy fields in Sungai Kakap District ranges from 0.58 to 13.38 ppm. The paddy field in Sungai Rengas Village has a high available P content, while the paddy field in Sungai Kakap Village has a very low P status. The results of analysis of total Pb in the rice fields of Sungai Kakap District ranged from 11.55 to 18.71 ppm, the status of total Pb content was classified as low. The relationship between the availability of P in the soil and the levels of Pb is very low (r = -0.33), it is suspected that Pb does not affect the state of P in the soil due to the low concentration of Pb. The ability of bacterial isolates to dissolve phosphate in this study varied. Phosphate solubilizing bacterial isolates from rice roots had a greater ability to dissolve phosphate than isolates from paddy soil, both isolates from the rice fields of Sungai Rengas Village and Sungai Kakap Village.Keywords: Phosphate Solubilizing Bacteria, rice, paddy fields, lead.INTISARIImmobilisasi Pb dalam bentuk ikatan dengan senyawa anorganik dapat terjadi dengan tersedianya solubilizing fosfat dalam jumlah besar di rhizosfer. Solubilizing fosfat yang tinggi di rhizosfer dapat menjadi indikasi adanya bakteri pelarut fosfat yang bekerja effektif di rhizosfer. Eksplorasi, isolasi dan karakterisasi bakteri yang menguntungkan ini perlu dilakukan, agar strain-strain yang mampu tumbuh baik di areal pertanaman padi dapat diperbanyak sebagai biofertilizer. Tujuan penelitian ini adalah mengkaji kandungan timbal (Pb) dan karakterisasi bakteri pelarut fosfat pada areal pertanaman padi di Kecamatan Sungai Kakap Kabupaten Kubu Raya. Penelitian ini menggunakan metode eksperimen lapang. Sampel tanah dari rhizosfer tanaman padi dan sampel tanaman padi dianalisis di laboratorium sesuai dengan variabel-variabel yang telah ditentukan. Hasil penelitian ini menunjukkan kandungan fosfat tersedia pada lahan sawah di Kecamatan Sungai Kakap berkisar 0,58 – 13,38 ppm. Lahan   sawah Desa Sungai Rengas memiliki kandungan P tersedia dengan status tinggi, sedangkan lahan sawah di Desa Sungai Kakap status P tersedianya sangat rendah. Hasil analisis Pb total di lahan sawah Kecamatan Sungai Kakap berkisar 11,55- 18,71 ppm, status kandungan Pb total ini tergolong rendah. Hubungan antara ketersediaan P di dalam tanah dengan kadar Pb sangat rendah (r = - 0,33), diduga Pb tidak mempengaruhi keadaan P di dalam tanah karena konsentrasi Pb yang rendah. Kemampuan isolat bakteri dalam melarutkan fosfat pada penelitian ini berbeda-beda. Isolat bakteri pelarut fosfat yang berasal dari  akar padi mempunyai kemampuan melarutkan fosfat yang lebih besar dibandingkan isolat dari tanah sawah, baik isolat yang berasal dari sawah Desa Sungai Rengas maupun Desa Sungai Kakap. Kata Kunci: Bakteri Pelarut Fosfat, padi, sawah, timbal.
