Abstract

The research objectives were to observe the growth and spore production of Metarhizium anisopliae grown at wheat-pollard and wheat-brand and to test the M. anisopliae pathogenicity on instar III rhinoceros beetle larva of coconut pest (Oryctes rhinoceros, L.). The research were executed in 3 phases : (1) Regeneration phase of  M. anisopliae, the experiment was arranged in single factor CRD with 3 kinds of wheat and 3  replications. The influences of the treatments on biomass, spore number and spore viability were observed then; (2) lethal dosage (LD50) determination phase; and (3) phatogenicity test of M. anisopliae, the experiment was arranged in 3 x 3 factorial CRD, where the first factor was the kinds of wheat (i.e. Pollard, Brand and Pollard Brand) and the second factor was the dosage of biopesticide (i.e. 0,5 LD50 LD50  and 2 LD50). The phatogenicity testing was conducted to evaluate the effects on toxicity, mortality speed, and effication percentage. The result indicated that the wheat-brand was the better medium for M. Anisopliae than the pollard and the pollard-brand ones. The average spore number (1021,67 x 1014  spora/ml), biomass (95,94 g) and the viability (127,00 x 108 spora/ml) were significantly higher than the others.  The lethal dosage obtained was 6,70g to gave the mortality percentage (73,33 %) and the effication percentage (73,33 %) significantly higher than the other treatments.

Abstract

Gunungkidul is a production center of cassava (Manihot esculenta Crantz), a carbohydrate source and raw material for food industry. AMF inoculation in cassava plants is known to increase biomass production. However, little studies have been conducted on the response of cassava to mycorrhizal inoculation and organic fertilizer. Therefore, this study was aimed at examining the effects of AMF inoculation and types of manure on the AMF colonization and yield of cassava in Gunungkidul. The research was carried out by planting cassava in Alfisol Gunungkidul arranged in a randomized complete block design with two factors, AMF doses of 25g; 50; and 75g/plant; and types of manure i.e. cow, goat, and poultry manure, for five months period. Rhizosphere soil and root samples were analyzed for AMF colonization and the spores number. The results showed that AMF-infected cassava roots combined with cow or goat manure application produced more spores than poultry manure. AMF infection and manure, thus, significantly resulted in better root proliferation, root forehead weight, tuber diameter, and cassava products, than the absence of both treatments. Cow manure combined with AMF at a dose of 25 g/plant significantly affected the dry weight of cassava roots. This study implies that applying AMF and manure provide a substantial contribution on the growth and production of cassava.

Abstract

This study aimed to determine the role of the indigenous rhizobacteria from Merapi as a substitute for compost in rice cultivation on coastal sandy land under drought stress. The study was a single-factor experiment, with types and doses of compost as treatments, arranged in a completely randomized design (CRD) consisting of seven treatments and three replications. The seven treatments tested were cow manure compost at doses of 30 and 40 tons/ha, chicken manure compost at doses of 30 and 40 tons/ha, Azolla compost at doses of 20 and 30 tons/ha, and without compost as a control treatment. Each experimental unit consisted of three plants for destructive sampling, three sample plants, and a substitute plant. The application of cow manure compost at a dose of 30 tons/ha to the rice plants inoculated with MB and MD isolates of Merapi indigenous rhizobacteria resulted in the best growth at five weeks after planting, which was not significantly different from that without compost application. This result indicated that the rice plants cv. Segreng Handayani inoculated with Merapi indigenous rhizobacteria, cultivated on coastal sandy soil under drought stress, even without the application of compost, could give the same responses as the plants treated with various types and doses of compost.
