Abstract

Inceptisols umumnya memiliki tingkat kesuburan tanah rendah sampai sedang. Upaya peningkatan ketersediaan hara tanah Inceptisol dengan pupuk anorganik NPK perlu diimbangi dengan aplikasi pupuk hayati dan amelioran organik. Percobaan ini bertujuan untuk mengurangi dosis pupuk NPK dengan menggunakan pupuk hayati dan amelioran organik serta meningkatkan hasil tanaman jagung. Percobaan dilakukan di Pasir Banteng, Kabupaten Sumedang. Penelitian menggunakan RAK faktorial. Pupuk hayati dengan amelioran organik sebagai faktor pertama sebanyak empat taraf: tanpa pupuk hayati dan amelioran (kontrol), diberi pupuk hayati, amelioran organik, dan gabungan keduanya. Faktor kedua yaitu dosis pupuk NPK empat taraf: 100%, 80%, 60%, 40% NPK dosis anjuran.  Dilakukan tiga kali ulangan. Hasil penelitian menunjukkan terdapat interaksi antara pupuk hayati, amelioran organik, dengan pupuk NPK terhadap tinggi tanaman, N-total tanah, bobot tongkol berkelobot dan tanpa kelobot. Pemberian pupuk hayati dan amelioran disertai pupuk NPK 100% dan yang tanpa diberi amelioran menghasilkan bobot tongkol tanpa kelobot sebesar 1.089 g dan 1.064 g per tanaman. Pemberian pupuk hayati dengan amelioran dan pemberian pupuk NPK 100% menghasilkan bobot pipilan per tanaman 526,08 g dan 539,08 g. Aplikasi pupuk hayati dan amelioran organik belum mampu mengurangi dosis penggunaan pupuk NPK pada Inceptisols asal Pasir Banteng. Inceptisols generally have low to moderate soil fertility. The effort to increase the nutrients availability in Inceptisol through the application of NPK fertilizers need to be balanced with biofertilizers and organic ameliorants. This experiment aimed to reduce the dose of NPK fertilizer by using biofertilizers and organic ameliorants and to increase maizeyields. The experiment was conducted in Pasir Banteng, Sumedang Regency. The factorial RBD was used. The biofertilizer with organic ameliorant as the first factor: no biofertilizer and no ameliorant (control), biofertilizer, organic ameliorant, and combination of both. The second factor was dose of NPK fertilizer: 100%, 80%, 60%, 40% of recommended NPK dose. It was repeated three times. The results showed that there was interaction between biofertilizer, organic ameliorants, with NPK fertilizers on plant height, N-total soil, weight of cobs with and without husk. The application of biofertilizer and ameliorant with 100% NPK fertilizer and without ameliorant were 1,089 g and 1,064 g of cobs without husks, respectively. The application of biofertilizer with ameliorant and 100% NPK fertilizer had a grain weight of 526.08 g and 539.08 g, respectively. The application of biofertilizers and organic ameliorants has not been able to reduce the dose of NPK fertilizer on Inceptisols from Pasir Banteng.

Abstract

 Interaksi sinergis antara tanaman-bakteri dapat digunakan untuk meningkatkan kinerja fitoremediasi tanah yang terkontaminasi hidrokarbon (HC). Penelitian bertujuan untuk karakterisasi plant growth promoting rhizobacteria: Azotobacter sp. dan Pseudomonas sp. dalam kinerja fitoremediasi limbah minyak bumi menggunakan tanaman sorgum (Sorghum bicolor L.). Penelitian menggunakan rancangan acak kelompok faktorial (RAK-Faktorial) terdiri dari inokulasi Azotobacter sp. sebanyak 0%, 1%, 2%, dan 3% per konsentrasi total petroleum hydrocarbon (TPH), dan inokulasi Pseudomonas sp  0%, 1%, 2%, dan 3% per TPH. Hasil penelitian menunjukkan bahwa tidak ada interaksi antara inokulasi Azotobacter sp. dan Pseudomonas sp. terhadap seluruh variabel respon. Namun, efek mandiri terlihat pada efisiensi biodegradasi HC, yaitu inokulasi Azotobacter sp dosis 3% berbeda secara signifikan dengan kontrol pada fase ke 4 minggu setelah tanam (MST), tetapi tidak signifikan pada fase 14 MST. Inokulasi Pseudomonas sp. tidak memberikan efek yang signifikan antar perlakuan terhadap efisiensi biodegradasi HC pada dua periode pengamatan. Populasi Azotobacter sp. dan Pseudomonas sp. menurun pada periode 4 MST, selanjutnya meningkat  pada periode 14 MST. Pertumbuhan tanaman sorgum mengalami retardasi selama 14 MST. Residu hidrokarbon terakumulasi lebih tinggi di bagian akar daripada di bagian tajuk tanaman. Azotobacter sp. dan Pseudomonas sp. berperan sebagai binding agent yang dapat menghambat serapan hidrokarbon oleh akar sorgum.ABSTRACTThe synergism interaction between plant-bacteria can be used to improve performance of phytoremediation hydrocarbon (HC) contaminated soil. The study aimed to characterize  Azotobacter sp. and Pseudomonas sp. in petroleum phytoremediation performance using sorghum (Sorghum bicolor L). The research used a randomized block design with two factors: Azotobactersp. inoculation 0%, 1%, 2% and 3% per total petroleum hydrocarbon (TPH) concetration, and Pseudomonas sp inoculation:  0%, 1%, 2% and 3% per TPH concentration. The results showed there was no interaction between Azotobacter sp. and Pseudomonas sp. inoculation to each response variable. The independent effect of 3% Azotobacter sp. to biodegradation HC efficiency was significantly different from the control at phase 4 weeks after planting (WAP), but not significantly different at phase 14 WAP. Pseudomonas sp. effect did not show a significantly different between treatments on the hydrocarbon biodegradation efficiency in the two observation periods. Azotobacter sp. and Pseudomonas sp. population decreased at period 4 WAP, then increased at period 14 WAP. The Sorghum growth was retarded during 14 WAP. Hydrocarbon residues accumulated higher in the roots than in shoot. Azotobacter sp. and Pseudomonas sp. act as a binding agent that can inhibit the hydrocarbons uptake by sorghum roots.
