a field experiment was conducted to study the effect of two organic fertilizers along with zinc and boron elements on some growth parameters, concentration and uptake of nutrients in millet (panicum miliaceum l.) by using factorial based on randomized completely block design with three replications in qaen region, iran. the main treatments were municipal solid waste compost and cow manure (each...

the higher levels of essential elements in soil may be caused in optimum yields and crop quality. so it seems to be necessary to examine different levels of nutrients like fe and zn on plants and their productivity. to evaluate effects of iron and zinc application on yield and yield components of pimpinella anisum an experiment was conducted at the research farm of urmia university in 2009. tre...

Barley is one of the popular crops cultivated since ancient time in world. main cereal produced World and it most among cereals has played a significant role development agriculture It commonly used for food, animal feed beverage value. The important factors that reduce yield barley poor soil fertility, blanket recommendation fertilizers, acidity (low pH), diseases insects, crop management prac...

Lemon balm (Melissa officinalis L.), a member of Lamiaceae family, is an important medicinal plant that has many useful properties. Micronutrients are necessary in low dose for the growth and the development of plants. Present research was conducted to study the effects of micronutrients including manganese (Mn) and copper (Cu) on morpho-physiological traits and essential oil of lemon balm. Fie...

With increased demand for traditional agricultural practices, they are increasingly insufficient. The use of nano-fertilizers is essential when aimed to increase plant production. In 2003, nanotechnology started be used in agriculture and food industry. This led change production systems. Nanotechnology has brought fundamental changes agriculture. included new tools have been detect pests treat...

Arsenic (As) contamination of rice grains and the generally low concentration of micronutrients in rice have been recognized as a major concern for human health. Here, we investigated the speciation and localization of As and the distribution of (micro)nutrients in rice grains because these are key factors controlling bioavailability of nutrients and contaminants. Bulk total and speciation anal...

There have been several recent developments in slow-release fertilizers. These materials supply nutrients continuously over an extended period in contrast to water soluble fertilizers which are immediately available after incorporation in moist soil. Slow-release fertilizers are not subject to rapid leaching loss and do not easily burn plants from over-application. The major need for slow relea...
