Fe2O3 and ZnO nanoparticles were synthesized by a fast microwave method. Nanostructures were characterized by X-ray diffraction  and scanning electron microscopy. The goal of bio-fortification is to develop plants that have an increased content of bioavailable nutrients in their edible parts. The micronutrients magnesium (Mg), manganese (Mn) and copper (Cu), boron (B) and calcium (Ca) are essen...

Fertilizer is a powerful productivity-enhancing input, but SSA uses very little. Historical trends are abysmal (Figure 1). In 1970, SSA used <5kg/ha while other developing regions used >15 kg/ha. In the 25 years from 1970 to 1995 fertilizer consumption grew only .23 kg/ha/year. Current use is only 9 kg/ha, down from OBJECTIVES AND METHODS: The research highs of 11-12. This contrasts sharply wit...

maize (zea mays l.) is one of the most important crops that used for food, feeding and industrial products and in iran a developing cultivation. in order to study of corn s reactions (hybrid bc666) to supply nutrients to organic nutrition (bacteria and manure) as summer sown in climate conditions of lorestan. an experiment was conduct in meteorology station of lorestan s agriculture research fi...

Secondary lucidophyllous forest is one of the dominant forests in human-dominated subtropical/warm-temperate regions in East Asia. There were few direct monitoring techniques to elucidate the following hypotheses: (a) self-thinning may govern the stand development process and (b) wood production decline can be observed during secondary succession in a lucidophyllous forest. We conducted a long-...

This paper presents a comparison of dry anaerobic digestion reactors fed with differently sorted municipal organic solid wastes. One reactor was fed with source sorted organic wastes and a second reactor was fed with mixed organic wastes consisting of grey wastes, mechanically selected municipal solid wastes and sludge. The two reactors utilised the same process (Valorga) and operational condit...

From hatch to 18 d of age broilers were fed starter diets with (0.9 kg/ton) or without direct fed microbial (DFM). At 18 d, birds were weighed and, within DFM treatment (trt), randomly assigned to battery pens. In Exp 1, a 2 x 2 factorial arrangement of nutrient density [control (C, 19.3% protein (CP), 0.84%, Ca 0.37% nonphytin P (nPP); and 17.1% CP, 0.8% Ca, and 0.3% nPP in the grower (Gr) and...

Phenotypic stability of 12 rice genotypes for plant height, days to maturity and yield were assessed at five different locations through regression and deviation from regression using Additive Main Effect and Multiplicative Interaction (AMMI) model. The result showed highly significant genotypic and G x E interaction. The G x E interaction influenced the relative ranking of the genotypes tested...
