Abstract

Utilization of acid soils for food crop development must be carried out because of land conversion. The main problem in acid soils is the unavailability of P nutrients. Utilization of Arbuscular Mycorrhiza on acid soils has been found to contribute to the availability of P nutrients. This study used a factorial randomized block design with 2 factors, namely the application of tofu waste and arbuscular mycorrhiza. Tofu waste dosage consists of 0, 125, 250 and 375 g/polybag and Arbuscular Mycorrhiza application, namely: 0, 6, 12 and 18 g/polybag. The results showed that the application of tofu waste at a dose of 375 g / polybag affected significantly and gave the best results for the parameters of plant height, number of branches, wet weight and dry weight of soybean crop stover. While the application of arbuscular mycorrhiza with the best dose of 18 g / polybag affected significantly to fresh weight and dry weight of the roots of soybean. However, the interaction between the two treatments did not affected significantly to all observed variables.

Abstract

Secondary metabolites from Mikania micrantha could be expected to control barnyardgrass (Echinochloa crus-galli) characteristics and have an effect on lowland rice. This research was aimed to screening of secondary metabolites in M. micrantha extract, obtaining the greater extract concentration in suppressing the barnyardgrass growth, and determine the impact on the lowland rice characteristics. This method used was Randomized Completely Block Design in non-factorial within the concentration rates of M. micrantha extract using ethanol 96% (0%; 20%; 40%; 60%; 80%; 100%, and herbicide 2,4-D dimethylamine at the dose of 1 l ha-1 as a comparison). Lowland rice and barnyardgrass characteristics were analyzed using F-test and followed by DMRT at 5% with SPSS software. The result showed that M. micrantha had secondary metabolites include alkaloids, flavonoids, and tannins. The concentration at 20 to 100% significantly decreased the fresh- and dry-weight of barnyardgrass with the highest suppressing found in 60% concentration by 65.91% and 67.92%, respectively compared to un-sprayed. The concentrations at 20% and 60% were classified as inhibiting the growth biomass of barnyardgrass. The concentrations at 20%, 60%, and 80% can still encourage the tillers growth of lowland rice. An extract concentration of M. micrantha at 20% can be applied to inhibit the growth of barnyardgrass biomass and stimulate the lowland rice tillers.
