Abstract Nutrient stratification of no‐till managed soil can affect test analysis levels plant‐available phosphorus (P). Research has suggested sampling to different depths due acidity, but little work been conducted investigate any change recommendations for immobile nutrients. The objective this study was determine the depth that had greatest relationship with yield response fertilizer‐P. sam...

abstract a field experiment was conducted to study the competitiveness of wheat cultivars against bromus japonicus at sistan agricultural research station during 2003. the experimental design was a randomized complete block assigned in factorial arrangement of treatments with four replications. six wheat cultivars comprised two natives (old cultivars; boulani and kalak-afghni), and four new-rel...

Crop production is one of the major interactions between humans and natural environment, in process, carbon translocated cyclically inside ecosystem. Data assimilation algorithm has advantages mechanism robustness yield estimation, however, computational efficiency still a obstacle for widespread application. To address issue, novel hybrid method based on combination Biomass Algorithm Wheat (CB...

The aim of the present investigation was to investigate the nutritional yield, nutrient density, stability, and adaptability of organically produced wheat for sustainable and nutritional high value food production. This study evaluated the nutritional yield of four minerals (Fe, Zn, Cu, and Mg) in 19 wheat genotypes, selected as being locally adapted under organic agriculture conditions. The ne...

A field experiment was conducted on deep vertisols of Bhopal, India to evaluate the manural potential of three organic manures: farmyard manure (FYM), poultry manure (PM), phosphocompost (PC) vis-a-vis 0%, 75% and 100% recommended dose of fertilizer-NPK and to find out the most productive cropping system at various combinations of organic manures and chemical fertilizers. The seed yield of inte...

Fructification and yield of the edible mushrooms Pleurotus pulmonarius and Stropharia rugosoannulata are clearly enhanced when wheat straw is supplemented with 30% Lolium perenne grass chaff. The bioactive compound in the methanol extract of grass chaff was identified as beta-adenosine. In vitro biological activity tests showed that 0.012 mg of beta-adenosine per ml of medium stimulated earlier...

Impacts of the Indian Ocean Dipole (IOD), two different types of El Niño/Southern Oscillation (ENSO): canonical ENSO and ENSO Modoki, on the year-to-year winter wheat yield variations in Australia have been investigated. It is found that IOD plays a dominant role in the recent three decades; the wheat yield is reduced (increased) by -28.4% (12.8%) in the positive (negative) IOD years. Although ...

Wheat (Triticum aestivum) growth and yield are depressed by physical and chemical interference of weeds. Recently, wild barley (Hordeum spontaneum) population has increased in wheat fields of many provinces of Iran. Since, little is known about the allelopathic effects of wild barley residues in soil, greenhouse studies were conducted to examine the effects of soil amended residues of wild barl...

Recent advances in crop research have the potential to accelerate genetic gains in wheat, especially if co-ordinated with a breeding perspective. For example, improving photosynthesis by exploiting natural variation in Rubisco's catalytic rate or adopting C(4) metabolism could raise the baseline for yield potential by 50% or more. However, spike fertility must also be improved to permit full ut...
