Abstract

Quality of biofertilizer such as arbuscular myorrhizal fungi could be improved through the selection of appropriate sterilization and composition of the medium. The objective of the experiment was to determine the effect of sterilization and carrier composition on root colonisation, root length and weight of sorghum root. A green house experiment was conducted in randomized block design. The factors were: 1. methods of sterilization (ie. control; autoclave; NaOCl 10%; Co-60 gamma irradiation), and 2. composition of the carrier of mycorrhiza (100% zeolite; 75% zeolite + 25% rice charcoal;  50% zeolite + 50% rice charcoal). Results showed that there was no interaction effect of sterilization and composition of carrier on root colonisation, root length and weight of sorghum root. However, different technique of sterilisation gave differences on root colonisation, root length and weight of sorghum root. Sterilization using NaOCl 10% was not recommended. Gamma Co-60 irradiation sterilization did not have difference with control and autoclave, however there was  tendency  that irradiation technique gave better results to all parameters measured.

Abstract

One effort to increase the productivity of soybeans in Inceptisols Jatinangor is through utilize inoculant of soil microorganisms such as nitrogen-fixing bacteria and phosphate-solubilizing bacteria in the form of specific biofertilizer (SB) for soybean plant without leaving inorganic fertilizer as a source of available nutrients to plants. This research aimed to determine fertilization management of N-P-K and specific biofertilizer in retaining N and P availability and yield of soybean. The Research was conducted from April to July 2016, arranged in Simple Randomized Block Design (RBD) and consisted of 10 treatments. The combination of biofertilizer and N-P-K were as follows; A = control (without fertilizer), B = Standard N-P-K, C = 0 N-P-K + 1 SB , D = 1/4 N-P-K + 1 SB, E = 1/2 N-P-K + 1 SB, F = 3/4 N-P-K + 1 SB, G = 1 N-P-K + 1 SB, H = 3/4 + 1/4 SB, I = 3/4 N-P-K + 1/2 SB dan J = 3/4 N-P-K + 3/4 SB. The results showed a dose of N-P-K and biofertilizer was recommended in the treatment E (250 kg ha-1 SB) and 1/2 N-P-K (37.5-50-50 kg ha-1). The dose was able to increase nitrogen and phosphor content in soil and plant, also on yield of soybean up to 0.4 t ha-1 or 32% of a standard N-P-K.

Abstract

Centella asiatica is a medicinal plant containing asiaticoside bioactive, this is considerably higher if grown in the highlands generally on Andisols. Conversely, phosphorus was deficient in Andisol soils. The experiment aimed to study effect of phosphate solubilizing bacteria (PSB) isolates from the rhizosphere of C. asiatica which can dissolve P, produce plant growth promoters, increase growth of C. asiatica and fertilization efficiency. The research was done at Soil Biology Laboratory, Agriculture Faculty, Universitas Padjadjaran and at the experimental field of Agricultural Technology Research and Assessment Installation Manoko, Lembang District, West Java, Indonesia. The research used a factorial randomized block design with three replications and two factors. The first factor were application techniques: control, root soaking, and soil watering. The second factor were dose of NPK fertilizer and soil conditioner: control, P fertilizer dose of 100%, soil conditioner, P fertilizer dose 75% + soil conditioner, and P fertilizer dose of 100% + soil conditioner. Three superior isolates were isolated from C. asiatica rhizosphere and have been identified as: Paraburkholderia caribensis strain MNL-133, Paraburkholderia caribensis strain DSM 13236, and Pseudomonas aeruginosa strain K19PSE24. The results showed that the application of PSB combined with a dose of P fertilizer and soil conditioner on C. asiatica affected the soil P available, the number of leaves, the number of stolons and plant dry weight.ABSTRAKPegagan (Centella asiatica) salah satu komoditas tanaman obat yang memiliki kandungan bioaktif asiatikosida. Asiatikosida lebih tinggi jika ditanam di dataran tinggi umumnya ordo Andisols. Defisiensi hara fosfor salah satu kendala budi daya pada tanah Andisol. Penelitian ini bertujuan mengkaji pengaruh bakteri pelarut fosfat (BPF) unggul yang diisolasi dari roofer tanaman pegagan yang mampu melarutkan P dan menghasilkan pemacu pertumbuhan tanaman pengaruhnya terhadap peningkatan pertumbuhan tanaman pegagan dan efisiensi pemupukan. Penelitian dilaksanakan di Laboratorium Biologi Tanah, Fakultas Pertanian UNPAD dan di kebun percobaan Instalasi Penelitian dan Pengkajian Teknologi Pertanian (IP2TP) Manoko, Lembang menggunakan Rancangan Acak Kelompok Faktorial dengan tiga ulangan. Faktor pertama adalah teknik aplikasi BPF: kontrol; perendaman akar; penyiraman pada tanah. Faktor kedua yaitu dosis pupuk NPK dan pembenah tanah, yaitu perlakuan kontrol, pupuk P dosis 100%, pembenah tanah, pupuk P dosis 75% + pembenah tanah, dan pupuk P dosis 100% + pembenah tanah. Isolasi BPF dari rhizosfer pegagan menghasilkan isolat unggul yaitu Paraburkholderia caribensis strain MNL-133, Paraburkholderia caribensis strain DSM 13236, and Pseudomonas aeruginosa strain K19PSE24. Hasil menunjukkan pemberian BPF dikombinasikan dengan dosis pupuk P dan pembenah tanah pada tanaman pegagan memberikan pengaruh terhadap P tersedia, jumlah daun, jumlah stolon, dan berat kering tanaman.
