QTL mapping for ear length and ear diameter under different nitrogen regimes in maize
Ear length (EL) and ear diameter (ED) are two of the most important traits in maize (Zea mays L.), related to yield and plant morphology. In this study, an F9recombinant inbred line (RIL) population was used to identify the quantitative trait loci (QTLs) controlling EL and ED under two nitrogen (N) regimes. As a result, 3 QTLs were detected under N rich environment, 1 for EL on chromosome 1 and 2 for ED on...

A calculation program for real-time production of ammonia gas in animal houses
Ammonia is the major air contaminant in poultry houses. Ammonia emissions from animal houses influence the atmospheric environment, since aerial ammonia is one of the so called greenhouse gases and has a negative effect on vegetation and ecosystems. There are many researches on ammonia emissions from the animal houses but, there aren’t such many researches on the real-time production of ammonia in the animal...

Variable rate fertilizer application in Turkish wheat agriculture: Economic assessment
Fertilizer application is one of the most important operations in agricultural production. Traditionally, fertilizer is applied onto the whole farmland regardless of the variations across the land. Soil cores are taken randomly through the field and mixed into a single sample, which is then analyzed, and consequently a unique fertility recommendation is made in accordance with the results. However, with this new...

Diversity of common bean (Phaseolus vulgaris L.) genotypes in iron and zinc contents under screenhouse conditions
Deficiencies in iron and zinc have health consequences for humans, such as anaemia, poor growth and development in children and low productivity in adults. To guarantee sufficient supply of iron and zinc through diet mainly consisting of staple foods, such as common bean (Phaseolus vulgaris L.), specific interventions in plant breeding are needed. However, seed mineral content has not been a selection criterion for...

Land use effect on soil and particulate organic carbon, and aggregate stability in some soils in Tunisia
Conversion of native forests to cultivation is usually accompanied by a decline in soil organic carbon and nutrients, and deterioration of soil structure. Our knowledge of this process must increase if we are to optimise the physical regeneration of degraded soils in semiarid areas. In this work we aim to (i) determine the relationship between aggregate stability and soil and particulate organic carbon (ii) to study the...
