An experiment was conducted to study the effects of lamtoro (Leucaena leucocephala) leaf supplementation in fermented kumpai grass (Hymenachne amplexia calis) based rations on the productivity of Bali cattle. Variables measured were dry matter and organic matter intakes, nutrient digestibility (dry matter, organic matter, crude protein, and crude fiber), body weight gain, and feed efficiency. T...

Changes in water content and dry weight were determined in control cells and those induced to cold harden in response to abscisic acid (ABA) treatment (7.5 x 10-5 molar). Bromegrass (Bromus inermis Leyss cv Manchar) cells grown in suspension culture at room temperature (230C) for 7 days acclimated to -28°C (LT50) when treated with ABA, or to -50C when untreated. ABA significantly reduced cell g...

An irrigation experiment was conducted with three cultivars (Hass, Ettinger and Fuerte) in the avocado plantation of the Akko Experiment Station, Israel, during 1974-80 to determine the effect of irrigation regimen in spring and autumn on tree growth and productivity. Two treatments (wet and dry) were tested in the spring and in the autumn. In spring the trees receiving the wet treatment were i...

in order to investigate the effects of water deficit at different growth stages of chickpea genotypes, determining the best drought tolerance index and genotypes, an experiment carried out in the saatlu agricultural research station of uromia in 2008-2009. the experiment was split plot based on the randomized complete blocks design with four replications, in which, four levels of irrigation as ...

A Karl Fischer method for determining water (dry matter) in animal feed and forages was collaboratively studied. Water was extracted from animal feed or forage material into methanol-formamide (1 + 1) directly in the Karl Fischer titration vessel by high-speed homogenization. The water was titrated at 50 degrees C with one-component Karl Fischer reagent based on imidazole. Ten blind samples wer...

The extremely cold and arid Antarctic dry valleys are one of the most environmentally harsh terrestrial ecosystems supporting organisms in which the biogeochemical transformations of carbon are exclusively driven by microorganisms. The natural abundance of (13)C and (15)N in source organic materials and soils have been examined to obtain evidence for the provenance of the soil organic matter an...

A delay in the mechanical transplantation (MT) of rice seedlings frequently occurs in Huanghuai wheat-rice rotation cropping districts of China, due to the late harvest of wheat, the poor weather conditions and the insufficiency of transplanters, missing the optimum transplanting time and causing seedlings to age. To identify how delaying transplanting rice affects the agronomic characteristics...
