A commercial scale biochar field trial was established on a farm in Québec, Canada in May 2008. A very fine, commercially available biochar from fast pyrolysis of wood waste was applied as received from the manufacturer using standard farm machinery. The target application rate was 5.6 t/ha, but an estimated 30% of the material was wind-blown and lost during handling, transport to the field, so...

Little attention has been paid to the diagnosis of deficiencies of micronutrients such as zinc (Zn) and boron (B) and secondary nutrient such as sulphur (S) in rainfed systems. We evaluated Zn, B and S status of 1617 farmers’ fields in 14 districts of the semi-arid tropical India. Results showed that most of the soil samples were low to medium in organic carbon contents. Results also revealed t...

. eight holstein cows in early lactating stage were used in a 4×4 change-over design within 4 periods of 21-d to determine the effects of alfalfa hay particle size and soybean oil supplementation on intake, digestibility, ruminal and blood metabolites, chewing activity, milk yield and compositions. four total mixed rations containing 20, 20 and 60% corn silage, alfalfa hay and concentrate respe...

We tested the hypothesis that increasing the number of metaxylem vessels would enhance the efficiency of water uptake in soybean (Glycine max) and decrease the yield gap in water-limited environments. A panel of 41 soybean accessions was evaluated in greenhouse, rainout shelter, and rain-fed field environments. The metaxylem number influenced the internal capture of CO2 and improved stomatal co...

Crop simulation models are valuable research tools in agricultural decision making. In order to increase its general applicability, models need to be evaluated in diverse conditions. To achieve this, CROPGRO-Soybean model was evaluated on Vertic Inceptisols in a climatically variable semi-arid tropical condition. The model predicted reasonably the temporal changes in leaf area index, biomass an...

The objective of this work was to isolate and characterize Bacillus bearing multiple plant growthpromoting traits from diseased roots of soybean and to further assess its inoculation effect on soil rhizosphere properties and nutrition in soybean. The isolate was putatively identified as Bacillus on the basis of cultural characteristics and FAMEs profile, and further sequencing of 16S rRNA gene ...

Intercropping is a sustainable practice to achieve higher production with the aim to limit external inputs. A field experiment was conducted at the research farm of the Faculty of Agriculture, University of Maragheh, Maragheh, Iran, during 2016 growing seasons with ten treatments to evaluate the yield, analyze the competition and insect’s assemblages in sunflower (as main plant)/soybean (as com...

intercropping is considered for increasing and stability of yield in per unit. in order to study the effects of soybean (glycine max l.) and millet (panicum miliaceum l.) replacement intercropping on agronomic traits, diversity of weeds and soil biological activity, an experiment was conducted at the research station of agricultural faculty, of bu-ali sina university, in 2014. the experiment wa...

to investigate the effect of deficit irrigation on quantitative and qualitative yield of soybean cultivars, an experiment was conducted as split plots based on randomized complete block design with three replications at agricultural research farm, university of guilan, during 2009. main factors were included four irrigation levels based on potential moisture 30-35 (i1), 50-55 (i2), 70-75 (i3) c...
