The application of organo-mineral fertilizers (OMFs) is gaining popularity day by because their potential effect on crop productivity and soil fertility enhancement. Therefore, this research was conducted to observe the a peat soil–urea (PSU) fertilizer baby corn yield, quality, nitrogen (N) use efficiency, quality compared with commercial urea. A completely randomized design (CRD) four replica...

Coccomyxa acidophila is an extremophile eukaryotic microalga isolated from the Tinto River mining area in Huelva, Spain. Coccomyxa acidophila accumulates relevant amounts of β-carotene and lutein, well-known carotenoids with many biotechnological applications, especially in food and health-related industries. The acidic culture medium (pH < 2.5) that prevents outdoor cultivation from non-desire...

The fertilizer requirement of tef varies from agro-ecology to and soil soil. Therefore, the objective this study was refine optimum phosphorus rate for under balanced fertilization. experiment conducted on-farm during main cropping season two consecutive years (2015-2016) in Vertisol at Ada’a District. had 8 treatments (six rates each with fixed amount N, K2O, S, Zn B, negative contr...

The present study was conducted to evaluate the serological changes (urea and creatinine) in kidneys of Nile tilapia (Oreochromis niloticus) after acute exposure Malathion. Four groups 15 fish were made each categorized as; Group A: (control group) Groups B, C D (experimental groups). LC50 Malathion 2µg/L at 96 hours tilapia. exposed sub-lethal concentrations 0.5, 1.0 1.5 µg/L group respectivel...

In this study 152 bacterial strains were isolated from the contaminated oils in the southwest of Iran. Hemolysis was used as a criterion for the primary  isolation of biosurfactant producing-bacteria. Fifty five strains had haemolytic activity , among them tweleve strains were good biosurfactant producers by measuring surface tension and emulsification activity.Two microorganism showe...

BACKGROUND: Deficit irrigation strategies were effective in saving volume of water. Potassium is an essential nutrient that affects most of the biochemical and physiological processes are involved in plant resistance to biotic and a biotic stresses. OBJECTIVES: This study was conducted to assess effect of different pattern of irrigation and several source...

ABSTRACT- Crop residue is applied to amend soil properties and increase crop yield. In this study, the effects of rapeseed residues and different rates of nitrogen on grain yield and yield components of sunflower and weed dry matter were investigated. The experiment was conducted at the Experimental Farm of College of Agriculture, Shiraz University, located at Badjgah, Shiraz, Iran in 2007-2008...
