Nutrients in the form of fertilizers and/or other additives such as amino acids, dramatically influence plant development and growth, plant nutrient composition and the level of soil pollution. Moreover, the treatment of soil microbiota is emerging as a new strategy in plant breeding to achieve desirable traits. Thus, integrated study of fertilizer application and soil microbiota might lead to ...

review and goals: the ajowan(carum copticum) is a medicinal plants from apiaceae family that seeds contains 2-4% of volatile oil. 9-17 of chemical composition of ajowan essential oil have been reported(2), it have antibacterial and antioxidant activity of it caused to preserve the food materials(1). the application of chemical fertilizer leads to environmental pollution and ecological disaster ...

A pot experiment was conducted in the open net house of the Department of Agricultural Chemistry, Bangladesh Agricultural University, Mymensingh from January to June, 2007, to study the effect of organic and inorganic fertilizers on the growth, leaf yield, chlorophyll and protein contents of Stevia rebaudiana (Bert.). The experiment was laid out in completely randomized design with three replic...

this experiment was carried out to evaluate the effect of rhizobium strains and plant growth promoting rhizobacteria(pgpr) on yield and yield components of chickpea (cicer arientinum l.) arman cultivar. this research was conducted as split plot based on randomized complete block design at zanjan university researchal farm. irrigation levels(optimum irrigation during season growth and no irrigat...

There seems to be conflicting information about foliar fertilizers and their timing of application to cotton. Much of the confusion lies in the variety of fertilizer products available. A cotton fanner now has a choice of applying foliar fertilizers (according to fertilizer labels) beginning at the first true leaf stage and continuing until defoliation. This newsletter will focus on available i...

A field study was conducted to determine the effect of organic and mineral-based fertilizers on phytochemical contents in the tubers of two cassava varieties. Treatments were arranged in a split plot design with three replicates. The main plot was fertilizer source (vermicompost, empty fruit bunch compost and inorganic fertilizer) and sub-plot was cassava variety (Medan and Sri Pontian). The am...

This paper assesses the origins of and changes to fertilizer policy in Nepal over a period of time. It assesses farmers’ awareness of the recent changes to the subsidy policy and examines their perceptions of the extension services. This paper looks at the environmental implications of the concentrated application of chemical fertilizer, particularly as far as food security is concerned. Questi...

Despite the fact that erosion undermines productivity in the Ethiopian highlands, adoption of fertility enhancing techniques remained very minimal. The objectives of this study is to examine factors affecting adoption of fertilize and manure use and their interrelationships using plot and household level data collected from 211 farm households. A two-stage probit model results revealed a negati...

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...

Effects of organic manure (poultry manure) applied alone and integrated with inorganic fertilizer (urea) on yield and yield component, N-uptake and soil fertility in wheat-maize cropping system was evaluated in a field experiment at Nuclear Institute for Food and Agriculture, Peshawar, Pakistan. Poultry manure was applied alone and were integrated in different proportions with mineral nitrogeno...
