Peanut is a food crop that has economic value and high protein. This study aims to determine the effect of effectiveness phosphate fertilizers on productivity peanuts. research was conducted at Experimental Garden Faculty Agriculture, Universitas Jabal Ghafur, starting from February June 2023. used randomized block design with non-factorial pattern, namely dose control, 5 g/plant, 10 15 g/plant...

long-term application of fertilizers containing p, especially organic fertilizers, usually increases the water soluble and available p of soil and at the same time may result in p accumulation in soil. organic fertilizers may also increase movement of p in the soil profile that could result in surface and ground water pollution. an experiment was conducted on field plots that received three app...

We develop an approach to utilize anisotropic metamaterials to solve one of the fundamental problems of modern plasmonics--parasitic scattering of surface waves into free-space modes, opening the road to truly two-dimensional plasmonic optics. We illustrate the developed formalism on the examples of plasmonic refractor and plasmonic crystal, and discuss limitations of the developed technique an...

Many farmers use organic fertilizers to preserve the environment, but unfortunately, it’s not as effective chemical fertilizers. In recent years, discovery of plant growth-promoting rhizobacteria (PGPR) has gained some attraction. PGPR have abilities promote growth efficiently, including corn plants. Corn (Zea mays L.) is a staple food needed in large quantities. Our results show that bacteria ...

increasing demand for food production in the recent years has raised the usage of granular fertilizers. consequently, the growing use of fertilizers has reduced the quality and quantity of crop production. in addition pollution problems such as soil and water (surface and subterranean water) contaminations has increased. consistent spreading of fertilizers in the farmlands is of fundamental rul...

in order to evaluation the effects of different soil fertility systems on chickpea seed quality, field experiments were carried out in sanandaj agriculture research station of iran in 2007 and 2008 growing seasons. experimental units were arranged in split-split plots based on randomized complete blocks with three replications. green manure levels considered main plots, base fertilizer compound...
