introduction cultivated sunflower is one of the largest oilseed crops in the world. sunflower seed is the third largest source of vegetable oil worldwide, following soybean and canola. nitrogen is one of the most important elements for crops to achieve optimum yields and quality. phosphorus (p), next to nitrogen, is often the most limiting nutrient for crop and forage production. phosphorus ava...

Across the world, a heavenly use of chemical fertilizer is major environmental issue in agricultural fields for sustainable growth of plants. Hence, the chemical fertilizers show adverse environmental effects in human life along with degrade the quality of soil fertility and polluting the water. So there is a need to develop an alternative approach to minimize the high consumption of chemical f...

We conducted a controlled experiment to test the plant vigor and the plant stress hypotheses. The two hypotheses associate plant physiological conditions to insect feeding mode and performance. We exposed tomato, Lycopersicon esculentum, to different types of growing conditions: optimal (vigorous plants), resource based stress (water and/or nutrient deficit), and physical stress (punched hole i...

Commiphora berryi (Arn)Englor (Burseraceae) is a well known plant in Tamil nadu, India. It is used in several parts of the state for various medicinal properties. The present work summarizes preliminary phyto chemical study of bark of this plant.

salinity tolerance is one of the most important affecting factors on agricultural production in arid and semi-arid areas. in order to study the effects of saline and fresh water irrigation with application of organic and npk fertilizers on cumin, a split plot experiment based on randomized complete block design was carried out with three replications during 2011 and 2012, at the research farm o...

This review discusses the occurrence and distribution (within a plant) of methyl eugenol in different plant species (> 450) from 80 families spanning many plant orders, as well as various roles this chemical plays in nature, especially in the interactions between tephritid fruit flies and plants.

Neighbors When the people of Midland, Michigan, heard in November 1998 that toxic dust had been spilled repeatedly at The Dow Chemical Company's plant there, concern and confusion followed. While the chemical giant kept largely silent, rumors spread about the chemicals contained in the dust and what effect they might have on humans and the environment. Some environmentalists accused Dow of tryi...

background: rosemary (rosmarinus officinalis l.) as a member of the lamiaceae family is a valuable aromatic and medicinal plant which is cultivated in large scale in iran. therefore, it is necessary to determine influence of factors affecting plant growth and drug metabolite production. objectives: this experiment was carried out to evaluate the effects of bio-stimulators compounds on growth an...

The general organization and function of the endomembrane system is highly conserved in eukaryotic cells. In addition, increasing numbers of studies demonstrate that normal plant growth and development are dependent on specialized tissue and subcellular-specific components of the plant membrane trafficking machinery. New approaches, including chemical genomics and proteomics, will likely accele...
