Abstract

Penelitian ini bertujuan untuk mengkaji efektivitas bio-invigorasi benih dan LEISA terhadap peningkatan pertumbuhan dan hasil tanaman padi gogo lokal. Penelitian di laksanakan di Laboratorium Agroteknologi dan di Rumah Kasa Kebun Percobaan Fakultas Pertanian Universitas Halu Oleo mulai Bulan Juli 2015 sampai Bulan Februari 2016. Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) dengan pola faktorial yang terdiri dua faktor. Faktor pertama yaitu bio-invigorasi  yang terdiri dari kontrol (tanpa aplikasi bio-invigorasi), serbuk bata merah + Bacillus sp. CKD061 dan serbuk arang sekam + Bacillus sp. CKD061. Sementara faktor kedua adalah LEISA yang terdiri dari kontrol (tanpa aplikasi pupuk organik plus dan anorganik), pupuk organik plus dosis  full, pupuk anorganik dosis full, pupuk organik plus dosis full + pupuk anorganik dosis full, pupuk organik plus dosis full + ½ dosis pupuk anorganik serta pupuk organik plus dosis full + ¼ dosis pupuk anorganik. Perlakuan yang diuji sebanyak 18 kombinasi percobaan dan setiap perlakuan diulang 3 kali sehingga terdapat  54 unit percobaan. Setiap unit percobaan terdapat 5 polibeg sehingga keseluruhan terdapat 270 polibeg. Data hasil pengamatan dianalisis menggunakan metode analisis ragam  dan dilanjutkan dengan uji jarak berganda Duncan jika perlakuan berpengaruh nyata pada α 0,05. Hasil penelitian menunjukkan bahwa interaksi perlakuan bio-invigorasi  benih dan LEISA menggunakan serbuk bata merah atau arang sekam yang dikombinasikan dengan pupuk organik plus dosis 2 ton ha-1 +  pupuk anorganik dengan dosis 200 kg ha-1 Urea, 150 kg ha-1 SP36 dan 100 kg ha-1KCL memberikan peningkatan tinggi tanaman umur  6 dan 12 MST, jumlah daun 8-14 MST, luas daun 6-12 MST dan jumlah anakan 6 dan 10 MST, yang lebih baik namun tidak berbeda nyata dengan perlakuan lainnya kecuali dengan kontrol, sementara itu, untuk pengaruhnya secara mandiri,  bio-invigorasi  benih serbuk bata merah + Bacillus sp. CKD061 atau serbuk arang sekam + Bacillus sp. CKD061 memberikan hasil  yang lebih baik dibandingkan dengan kontrol, dan untuk LEISA, (semua perlakuan yang diuji kecuali kontrol) memberikan efek yang sama dalam meningkatkan pertumbuhan dan hasil padi gogo. Kata Kunci: Rizobakteri, Bio-Invigorasi benih, LEISA, Padi gogo

Abstract

The objective of this research was to evaluate the effect of seed invigoration on improving seed viability and vigor, and to overcome problems of postharvest physiological dormancy of upland rice seed. The research was conducted from February to June 2011 at Agrotechnology Laboratory, Faculty of Agriculture, Halu Oleo University. The experiment used randomized complete design which consisted of 13 treatments, i.e control (G0), Hidration-Dehidration (G1), Matriconditioning using ground brick (G2), Matriconditioning using ground burned-rice husk (G3), Bacillus CKD061 (G4), P. fluorescens PG01 (G5), Serratia CMN175 (G6), Biomatriconditioning using ground brick + Bacillus CKD061 (G7), Biomatriconditioning using ground brick + P. fluorescens PG01 (G8), Biomatriconditioning using ground brick + Serratia CMN175 (G9), Biomatriconditioning using ground burned-rice husk + Bacillus CKD061 (G10), Biomatriconditioning using ground burned-rice husk + P. fluorescens PG01 (G11), Biomatriconditioning using ground burned-rice husk + Serratia CMN175 (G12). Each treatment was replicated three times, therefore, overall there were 36 experimental units. Data obtained were analyzed using analysis of variance and followed with Duncan’s Multiple Range Test. The research results showed that bio-invigoration treatments integrated with rhizobacteria were effective to overcome the problems of postharvest physiological dormancy when local upland rice seeds were harvested. In addition, this treatment was also able to increase viability and vigour of the seed. Among treatments tested, the use of Bacillus sp. CKD061 or P. fluorescens PG01, either independently or integrated with matriconditioning using ground brick or ground burned- rice husk was more effective in improving viability and vigour of local upland rice seed compared to other treatments.

Abstract

The research aimed to know biochemical characters of rhizobacteria from broadleaf weed that are potential as deleterious rhizobacteria. The research was conducted at Agronomy Laboratory   of Agriculture Faculty   Halu Oleo University Kendari from January until March 2013. The results showed that   9 of 10 rhizobacteria isolates tested from broadleaf   weeds   rhizosphere   had   the   ability   to   solubilize   phosphate   with   different diameters. For nitrogen fixation ability, all isolates tested were potential but only isolates of ML-01 and KL-06 had high capability. All isolates had different ability to produce IAA, with isolates of   KL-06 produced higher concentration of   IAA (33,07 ppm) compared to other isolates. Isolates that had the ability to produce HCN  were isolates BL-07, with filter paper change from yellow to dark brown, and BL-08 and BL-03 light brown color changes indicated to that the production of  HCN  was increased. Result of research showed that some isolates tested had biochemical character as deleterious rhizobacteria by  the ability to solubilize phosphate, fix nitrogen, produce IAA and HCN. Keywords: biochemical characterization, rhizobacteria, broadleaf weeds, deleterious.
