Background Maize fodder is being used as staple feed for livestock but it lacks protein and essential amino acids; lysine and tryptophan. Intercropping maize with leguminous soybean crop is promising technique under limited land resources of South Korea but it can only give considerable advantages when adequate distance is provided between corn and soybean rows. Main aim of present study was to...

Averaged across crop, year and season , residue cover reduction was significantly less for coulter-type applicators than for disk-type applica-tors (P<0.001), disk-type applicators reduced residue cover significantly less than chisel and sweep injectors (P<0.001), and chisel and sweep injec-tors reduced residue cover similar to a tandem disk (P=0.398). Ranges of values to estimate the percentag...

This experiment was conducted in the Research Farm of the Faculty of Agricultural Sciences, University of Guilan in 2010 as an RCBD based split plot experiment with three replications. In this experiment five different amounts of soil moisture (Irrigation after depletion of 45, 55, 65, 75 and 85% of field capacity moisture) and two soybean cultivars (Gorgan-3 and Williams) was considered as mai...

Intercropping of corn and soybean is widely practiced in agricultural production. However, few studies have investigated the effect intercropping fertilizer reduction on yield. In present study, were interplanted 2:2, 2:3 2:4 ratios. Two levels (normal: 600 kg/ha VS. reduced: 375 kg/ha) set. The effects planting patterns growth yield soybeans studied based changes enzyme activities related to n...

Transgenic glyphosate-resistant (GR) soybean [Glycine max (L.) Merr.] expressing a glyphosate-insensitive 5-enolpyruvylshikimate-3phosphate synthase (EPSPS) enzyme has provided new opportunities for weed control in soybean production. However, glyphosate is toxic to the soybean nitrogen-fixing symbiont, Bradyrhizobium japonicum, as its EPSPS enzyme is sensitive to glyphosate. The effects of gly...
