Volume 74

Online since: March 2019

Description: This volume of the International Letters of Natural Sciences encompasses recent research on evaluation of the effect of inoculation with various biofertilizers on the growth, biochemical and yield of Arachis hypogea L. at various stages; characterization of the microbial community in a constructed wetland system planted with Cyperus alternifolius L. treating sewage contaminated with heavy metals; assessment of the water quality of rivers around Warri metropolis in Delta state of Nigeria using water quality index; estimation of the impact of metal pollution in Skikda and Jijek bays of Eastern Algeria via the studying of the bioaccumulation of cadmium and lead in red mullet Mullus barbatus Linnaeus, 1758.
The issue is closed by the article devoted to the determination of the geographic pattern with the aim of providing interlinking between the climatic and hydrological components of natural resources.

Description:

This volume of the International Letters of Natural Sciences shows the latest findings concerned with evaluation of the exogenous application of licorice root extract on the changes of growth, yield, biochemical components, heavy metal accumulation, and the antioxidant defense system of Capsicum annuum L. grown on a saline soil contaminated with heavy metals as well as development of the approach to the assessment of trace metal impact on plants in polluted ecosystem by the estimation of the influence of trace metals (Cd, Pb, Cu, Co, Ni, Zn) on plants of Hordeum vulgare L. in different soils and also evaluation of the antioxidant activity, grain quality content and grain traits of Afghanistan selected rice varieties.

The last article of the issue is devoted to a new approach in biology – biodynamic agriculture. The method is demonstrated by the studying the effect of using biodynamic calendars on the mucilage content and germination behavior in three ecotypes of Basil (Ocimum sp.).
