Nutritional value of diets based on a low-quality grass hay supplemented or not with urea and levels of cassava meal

  Ten Polwarth ´ Texel lambs (30±1kg live weight (LW)), housed in metabolic cages and fedad libitum a low-quality grass hay (Cynodon ssp.) were used in a replicated 5 × 5 Latin Square experiment to evaluate effects of non-protein N (NPN) and levels of a non-fibre carbohydrate (NFC) source (cassava meal) supplementation (0, 5, 10 and 15 g/kg of LW) on intake, digestibility, N...

Impact of hexaflumuron, a chitin synthesis inhibitor, on growth, development and reproductive performance of the progeny in Callosobruchus maculatus after adult treatments

  Hexaflumuron, a benzoylphenylurea derivative, was tested topically at four doses (0.5, 1, 1.5 and 2 µg/insect) on adults of Callosobruchus maculatus (Coleoptera: Bruchidae) and first evaluated on fecundity, hatchability and viability of eggs, longevity and morphometric of oocytes. Our data show that the compound reduced the longevity and the fecundity. In addition, treatment affected...

Some physical properties of the watermelon seeds

  Watermelon seeds of three major local Iranian varietiesSarakhsi, Kolaleh and Red, at the moisture content of 4.55, 4.75 & 5.02% (w.b.), were selected to study the physical properties, respectively. Linear dimensions, mean diameters, sphericity, surface area, volume, true and bulk densities, porosity, repose angles and static coefficient of friction of the three varieties’ seeds were measured using...

Influence of genotypes, planting methods and weed management on competitiveness of wheat (Tritcum aestivum L.) and Phalaris minor Retz

  Field experiments were conducted at the research farm of Punjab Agricultural University, Ludhiana during 2003-04 and 2004-05. The soil of the experimental site was loamy sand in texture and neutral in reaction rating low in organic carbon and nitrogen, and medium in phosphorus and potassium. Bread wheat genotype PBW 343 tended to reduce the values for dry matter accumulation and density of Phalaris...

Effect of three different treatment levels of deltamethrin on the numbers of dung beetles in dung pats

  The effect of 3 different treatment levels of the pyrethroid deltamethrin on the numbers of dung beetles (Families, Hydrophilidae, Scarabidae and Staphilinidae) were investigated. A known quantity of cow dung was thoroughly mixed with a premeasured quantity of deltamethrin that would give the required concentration. Dung was exposed in the field for 1 week, collected and washed out to determine the number of...

Lithological Mapping of the Unsaturated Zone of a Porous Media Aquifer to Delineate Hydrogeological Characteristic Areas:Application to Israel's Coastal aquifer

  With water quality steadily decreasing, decision-making with regard to water supply must improve aquifer management models, which are  based upon various assumptions. Amongst these are assumptions concerning subsurface aquifer lithology. The objective of this study is to present a means of improving information and assumptions, as well as providing guidelines to characterise the unsaturated zone media....
