introduction: increasing usage of chemical fertilizers imposes irreparable damages to the environment. disadvantages of chemical fertilizers has led to more attention to the application of organic fertilizers and manures. the use of organic fertilizers and livestock, especially in nutrient poor soils, it is necessary to maintain soil quality. plant growth promoting rhizobacteria (pgpr) occupy t...

Three seasonal ornamental plants, namely Petunia hybrida, Callistephus chinensis and Impatiens balsamina, were tested for their response to inoculation with mixed indigenous AM culture when grown on a marginal wasteland amended with organic matter. Subsequently, the treatments consisting of AM inoculations were compared with those consisting of recommended chemical fertilizers in terms of growt...

in order to study the effects of magnetic field, silver nano particles and micronutrient fertilizers on sugar beet, an experiment was conducted at razavi research and technology institute, mashhad, iran. experiment carried out with seven treatments based on randomized complete block design with three replications. treatments included (t1) magnetic field and silver nano particles + kemira fertil...

A study was conducted to assess the impact of different nutrient combination of field tomato on post harvest storage life and organoleptic quality of fresh fruits. Fourteen different treatment combinations comprising two organic manures (Farmyard manure and vermicompost), inorganic fertilizers and biofertilizer in different levels were laid out in RBD with three replications during 2005-06 and ...

Fertilization plays an important role in crop growth and soil improvement. This study was conducted to determine the best fertilization system for wheat production. Experiments were arranged in a complete block design with three replications in two years. Main plots consisted of six methods of fertilization including (N1): farmyard manure; (N2): compost; (N3): chemical fertilizers; (N4): farmya...

Organic fertilizers play a significant role in organic systems and sustainable soil management. In general, organic fertilizers increase soil fertilization so can reduce the negative effects of the excessive use of chemical fertilizers and synthetic man-made fertilizers. This study was carried out in the Medicinal Plants Farm of Shahid Bakeri Higher Education Center of Miandoab during summer 20...

Tillage operation and fertilizer type play important roles in soil properties as far as soil microbial condition is concerned. Information regarding the simultaneous evaluation of the effect of long-term tillage and fertilization on the soil microbial traits of soybean farms is not available. Accordingly, it was hypothesized that, the microbial biomass and enzyme activity, more often than not, ...

Salinity is the leading abiotic stress hampering maize ( Zea mays L.) growth throughout the world, especially in Pakistan. During salinity stress, the endogenous ethylene level in plants increases, which retards proper root growth and consequent shoot growth of the plants. However, certain bacteria contain the enzyme 1-aminocyclopropane-1-carboxylate (ACC) deaminase, which converts 1-aminocyclo...
