Identification of molecular marker linked to stem rust resistance gene in synthetic hexapolid lines of wheat (Triticum aestvium L.)

  In order to enrich the molecular markers linked to wheat stem rust resistance gene and to facilitate the marker-assisted selection in breeding programme, bulk segregation analysis was carried out for gene tagging using F2 segregating population derived from cross between wheat synthetic 4 line with resistant gene (Sr gene carrier) and a common wheat variety Agra local (susceptible to wheat stem...

Tillage system and genotype effects on early vigor and water use in bread wheat in the Mediterranean region

The southern part of the Mediterranean basin is among the regions that are characterized by recurrent droughts and it is threatened by the effects of climate change. To deal with these problems in wheat, improved techniques of rain water conservation and adapted varieties need to be developed. Combining zero tillage and varieties with early vigor can reduce evaporation and improve transpiration and water productivity...

Growth, haematology and serum biochemistry of broilers fed probiotics based diets

An experiment was conducted with a total of one hundred and twenty one-day old Marshall broiler chicks to determine the effect of probiotics (Biovet-YC and Gro-Up) on the performance characteristics, haematology and serum biochemistry of broilers. A completely randomized design was used and the experiment lasted for eight weeks. The birds were grouped into three treatments (T1, T2 and T3 respectively). T1 served as the...

Estimation of constant elasticity of substitution (CES) production function with capital and labour inputs of agri-food firms in Tanzania

This paper focused on estimation of the impact of capital and labour inputs to the gross output of agri-food products using constant elasticity of substitution (CES) production function in Tanzanian context. The CES production functional form was estimated by maximum likelihood estimator (MLE). The empirical results revealed that capital and labour inputs have impacted the gross output of the agri-food products by 97,...

Genetic variability and heritability studies in Gerbera jamesonii Bolus

Twelve genotypes of gerbera (Gerbera jamesonii) were evaluated to determine the genetic variability, heritability, genetic advance, and genetic advance as percent of mean for 13 contributing characters. Significant variations were recorded for the various characters studied. Phenotypic and genotypic coefficients of variation were highest for the number of leaves per plant, number of clumps per plant and leaf area index,...

Comparative analysis of volatile constituents in Bacillus thuringiensis (Bt) cotton (RCH2 Bt) and non-Bt cotton by gas chromatography-mass spectrometry

The differences in composition and concentrations of volatile allelochemicals between transgenic Bacillus thuringiensis (Bt) cotton and non Bt cotton leaves were compared and analyzed by using gas chromatography-mass spectrometry (GC-MS). The dominant compounds present in both non Bt and Bt cotton leaves were α-caryophyllene (4.62, 1.42), β-myrcene (3.67, 3.68), β-carene (0.31, 0.80), benzene...

Effects of cattle and manure management on the nutrient economy of mixed farms in East Africa: A scenario study

This paper explores effects of animal and manure management in a dairy unit on the nutrient economy of crop-livestock farms in East Africa. For this purpose, 8 cattle management scenarios have been developed based on farming systems in Mbeere, Kenya (extensive), Wakiso, Uganda (semi-intensive) and Kibichoi, Kenya (intensive). Three baseline scenarios represent present-day cattle management; five improved scenarios use...

Study on the quality and safety aspect of three sun-dried fish

Market samples of three sun-dried freshwater fish species namely Indian major carp (Labeo rohita), snake headed fish (Channa striatus), and a type of eurasian catfish (Wallago attu) were included in this study. The quality of the sun-dried fish samples were evaluated by examining physical properties, biochemical composition, and reconstitution behaviour. The safety aspect of the sun-dried fish samples were studied by...

Correcting soil acidity with the use of slags

Soil acidity correction is mandatory for plants to reach their production potential. Lime is the most used product; however, it has hindrances for action in depth, especially when liming is broadcast on the soil surface. Silicates (or slags), originating from the industrialization of iron and steel, are byproducts that present corrective effect. These two types of corrective differ on specific area (contact area) and in...
