Land-use conversion from woodlands to tea fields in subtropical areas of central China leads to increased nitrous oxide (N2O) emissions, partly due to increased nitrogen fertilizer use. A field investigation of N2O using a static closed chamber-gas chromatography revealed that the average N2O fluxes in tea fields with 225 kg N ha(-1) yr(-1) fertilizer application were 9.4 ± 6.2 times higher tha...

The application of microbial inoculants (biofertilizers) is a promising technology for future sustainable farming systems in view of rapidly decreasing phosphorus stocks and the need to more efficiently use available nitrogen (N). Various microbial taxa are currently used as biofertilizers, based on their capacity to access nutrients from fertilizers and soil stocks, to fix atmospheric nitrogen...

to evaluate the effect of drought stress, biofertilizer and chemical phosphorus fertilizer on yield and seed protein percentage of two lentil cultivars, an experiment was conducted in split factorial based on crbd design with 4 replications in research farm of university of tehran (karaj-iran) during 2009-10. the main factor including three irrigation levels (irrigation after 70, 90 and 130 mm ...

plant growth promoting bacteria with various mechanisms such as an increase in uptake and availability of nutrients can improve plant growth. in order to evaluate the effects of biofertilizers and vermicompost on quantitative characteristics and essential oil content of vegetative parts of summer savory, a field experiment was conducted during growing season of 2008- 2009 at agriculture researc...

Abstract. Prihartin I, Ismail AS, Sukorini H, Nursandi F, Zakia A, Farahdina FAR. 2023. Identification of bacterial isolates Tumpang and Bumiasri (East Java, Indonesia) using 16S rRNA gene sequencing screening their active compounds as a biofertilizer. Biodiversitas 24: 3338-3343. The objective the study was to identify (TPG) (BAS) screen-on biofertilizer active-compounds. Research materials us...

introduction castor plant, ricinus communis l. is a species of flowering plant in the spurge family; euphorbiaceae, which contains a vast number of plants mostly native to the tropics. it belongs to a monotypic genus ricinus. the name ricinus is a latin word for tick. the plant is probably named because its seed has markings and a dump at the end that resemble certain ticks (ncri, 2014). castor...

Biofertilizer Ning shield was composed of different strains of plant growth promotion bacteria. In this study, the plant growth promotion and root-knot nematode disease control potential on Trichosanthes kirilowii in the field were evaluated. The application of Ning shield significantly reduced the diseases severity caused by Meloidogyne incognita, the biocontrol efficacy could reached up to 51...
