nodulations, nitrogen fixation and growth characteristics of chickpea under metribuzin herbicide application

Response of Chickpea to Rhizobium Inoculation I. Nitrogen Fixation

Engineering Pseudomonas protegens Pf-5 for Nitrogen Fixation and its Application to Improve Plant Growth under Nitrogen-Deficient Conditions

Nitrogen is the second most critical factor for crop production after water. In this study, the beneficial rhizobacterium Pseudomonas protegens Pf-5 was genetically modified to fix nitrogen using the genes encoding the nitrogenase of Pseudomonas stutzeri A1501 via the X940 cosmid. Pf-5 X940 was able to grow in L medium without nitrogen, displayed high nitrogenase activity and released significa...

Growth and nitrogen fixation of tropical Acacias

Nitrogen is mainly lost from most Australian tropical savanna ecosystems via fire and replenished through symbiotic nitrogen fixation. The frequency and severity of bushfires in Australia, which are common and extensive in tropical savannas, are expected to increase under climate change. Thus the nitrogen loss from tropical savannas can be exacerbated. This research investigates how climate cha...

Removal of Metribuzin Herbicide from Aqueous Solution Using Corn Cob

Agricultural solid waste (corn cob) has been investigated asbiosorbent for removal of metribuzin herbicide from aqueous solution. Parameters influencing extraction efficiency such as pH of the sample, contact time of sample with biosorbent, shaking time, temperature, heating time, sorbent dose were studied. Maximum sorption of metribuzinwas found at pH 5.0. The sorption of metribuzin on corn co...

Plant Growth-Promoting Rhizobacteria Inoculation to Enhance Vegetative Growth, Nitrogen Fixation and Nitrogen Remobilisation of Maize under Greenhouse Conditions

Plant growth-promoting rhizobacteria (PGPR) may provide a biological alternative to fix atmospheric N2 and delay N remobilisation in maize plant to increase crop yield, based on an understanding that plant-N remobilisation is directly correlated to its plant senescence. Thus, four PGPR strains were selected from a series of bacterial strains isolated from maize roots at two locations in Malaysi...

Effect of Organic Matter and Biofertilizers on Chickpea Quality and Biological Nitrogen Fixation

In order to evaluation the effects of soil organic matter and biofertilizer on chickpea quality and biological nitrogen fixation, field experiments were carried out in 2007 and 2008 growing seasons. In this research the effects of different strategies for soil fertilization were investigated on grain yield and yield component, minerals, organic compounds and cooking time of chickpea. Experiment...
