Plants nutrients supply from the chemical fertilizer is the key to increasing agriculture production by enhancing the land productivity. However, the demand-supply gap of fertilizers in India has increased in recent times, thereby leading to increased dependency on imports .India imports which were about 2 million tonnes in early parts of 2000 increased to 10.2 million tonnes of fertilizers in ...

To establish DRIS norms in sugar beet (Beta Vulgaris L.) and compare them with DOP index, leaf samples were collected from 57 fields and N, P, K, Ca, Mg, Fe, Mn, Zn, Cu and B concentrations were determined. On the bases of crop yield, the fields were divided into two groups with low and high yielding performances. Standard DRIS norms were established for the different nutrient ratios. DRIS indi...

In Iran, fertilizers are mainly applied directly to soil. In such conditions, the yield and fertilizer use efficiency are usually low. The simultaneous application of fertilizers and irrigation water (fertigation) is an appropriate alternative to increase the efficiency of applied water and fertilizers. The objective of this study was to investigate the effect of various irrigation and fertiliz...

It is very difficult to meet the demands of increasing population with such fewer resources. Loss soil fertility, pests, and lack nutrients has resulted in a decrease agricultural production. This increased importance fertilizers agriculture. Since chemical adversely affect biofertilizers were brought into use. These are substances that contain living or latent cells, even micro-organisms. They...

Background and Objectives: Multiple Sclerosis (MS) is the most prevalent autoimmune disease of the central nervous system, and it has been suggested that nutrition might play a role in the etiology of MS. This study was aimed to evaluate the relationship between MS risk and intake of some macro- and micro-nutrients in Tehran (Iran). Materials and Methods: In this hospital based, case-control s...

Rose flower (Rosa hybrida) is appreciated for its beauty, fragrance and long period of flowering. To study the response of cut rose flower to bio-fertilizers, a factorial experiment was performed, with completely randomized design and four replications, in hydroponic greenhouse of Alandasht, Astane Ghods Garden, Mashhad, Iran, during 2009-2010. The first factor was six cultivars of rose flower ...
