NITROGEN EFFECIENCY IN BARELY UNDER SALINE-SODIC CONDITIONDS AS AFFECTED BY UREA, COMPOST AND BIOFERTILIZER (Rhizobium radiobacter sp.)

Soil genesis as affected by topography and depth of saline and sodic ground water under semiarid conditions of iran

Isolation of a strain of Agrobacterium tumefaciens (Rhizobium radiobacter) utilizing methylene urea (ureaformaldehyde) as nitrogen source.

Methylene ureas (MU) are slow-release nitrogen fertilizers degraded in soil by microbial enzymatic activity. Improved utilization of MU in agricultural production requires more knowledge about the organisms and enzymes responsible for its degradation. A Gram-negative, MU-degrading organism was isolated from a soil in Sacramento Valley, California. The bacterium was identified as Agrobacterium t...

Evaluation of Quantitative and Qualitative Traits of Chickpea as Affected by Biofertilizer, Nitrogen, and Humic Acid in Dryland Condition

In order to evaluate biofertilizer, nitrogen and humic acid effect on quantitative and qualitative traits of chickpea (ILC 482 line) this research was carried out at the Agricultural Research Field of Kurdistan University, Sannadaj, Iran. A factorial experiment was conducted based on a randomized complete block design with three replications. Experimental treatments included three levels of lea...
