effects of various fertilizers such as farmyard manure (fm), urea, and plant growth promoting rhizobacteria (pgpr, including the genera azotobacter and azospirillium) were checked on yield, fatty acids, protein, and oil contents of sunflower. a two-year field experiment was conducted in a semi-arid region in iran in 2007 and 2008. the experiment was a split plot in a randomized complete block d...

Farmyard manure, an amendment traditionally used for improving the fertility of sandy soils in arid climates, is becoming scarce and expensive. Its shortage makes it necessary to evaluate, at field scale, suitability medium-term performance other cheap, highly available substitutes. A trial was established analyze effects a single application three organic residues on barley yield nutrient upta...

The effect of integrated use of mineral and organic N sources (farmyard manure, poultry manure, and Filter Cake) on yield and N uptake of wheat were assessed in biennial field experiment carried out on silty clay loam soil in Nuclear Institute for Food and Agriculture, Tarnab, Peshawar Pakistan during 2005-07. Combined dose of N provided from all sources was applied @120 kg ha-1. There were 17 ...

The invasive African black beetle Heteronychus arator F. is a serious pest of crops in Tropical and sub Tropical regions, including East Africa. Literature on ecology of this pest in Sub Saharan Africa is scarce. Dispersal and abundance of H. arator were determined in maize fields in Njombe Region, in the Southern highlands of Tanzania, from December 2013 to May 2014. Adults of H. arator were c...

Laboratory, growth chamber and multiyear field studies were conducted with prominent cropping systems of the subtropical northwestern states of India including rice–wheat, rice–mustard, rice–rapeseed, soybean– wheat, soybean–rapeseed, groundnut–wheat, and groundnut–sunflower by including legumes (moongbean, cowpea, sesbania, pigeon pea) to investigate the role of integrated nutrient management ...

The causative agents of many infectious diseases are excreted by the faecal route and also with other excretions or secretions of the body. Some pathogens are also excreted from clinically healthy animals, from those with latent infections and in cases of transmissible multifactorial diseases. In all types of livestock housing, the pathogens finally reach the floor with the installations for co...

Emissions of ammonia to the atmosphere are considered a threat to the environment and both United Nation treaty and European Union legislation increasingly limit emissions. Livestock farming is the major source of atmospheric NH3 in Europe and field applied manure contributes significantly to the emission of NH3 from agriculture. This paper presents a review of studies of NH3 emission from fiel...
