An experiment was conducted at the Agronomy Field Laboratory of Bangladesh Agricultural University, Mymensingh during Kharif-II season 2005 to investigate the effect of row spacing and cultivars on the growth and yield of soybean. Three soybean cultivars: (1) Bangladesh Soybean -4 (G- 2), (2) BARI soybean -5 (BS-5) and (3) Shohag (PB-1) and four row spacings, (1) 20 cm, (2) 30 cm, (3) 40 cm and (4) 50 cm were used in the experiment in a split-plot design with row spacing in the main plot and cultivars in the sub-plot. Seeds were sown on 26 July 2005 at specified rows maintaining 5 cm plant to plant distance. The highest seed yield was obtained from 20 cm spacing and yield decreased with increased spacing irrespective of cultivars. Among cultivars the highest yield was given by cultivar BS-5 which was followed by PB-1. It was concluded that the soybean cultivars BS-5 and PB-1 could be selected for sowing in Kharif-II season and should be planted at 20 cm apart rows for achieving higher yield.

Hill Plots

Soybean (Glycine max (L.) Merr.) cultivars were tested for yield at various populations in hillplots that had plants compactly clumped and in comparative hill and row plots. Results indicated that thinning to a uniform stand should be worthwhile in cases where population varies and that selection in hills for material to be grown in rows could be from 43 to 95% as effective as direct selection in row plots.Key words: Glycine max, soybean cultivars, plant density, yield, hill plots, selection

Over The Top

Ten commercial soybean [Glycine max (L.) Merr.] cultivars were evaluated for reaction to over-the-top applications of two rates of 3′,4′-dichloropropionanilide (propanil) at the growth stage when three nodes on the main stem had completely unrolled leaves. Propanil, a herbicide commonly applied to rice [Oryza sativa L.] for control of grass weeds, was applied at 0.56 and 3.36 kg/ha; the higher rate is commonly used for control of weeds in rice. ‘Davis’, ‘Hood’, and ‘York’ soybean cultivars were damaged more by propanil than ‘Hill’, ‘Lee’, ‘Lee 68’, ‘Pickett’, ‘Semmes’, ‘Bragg’, or ‘Dare’ when damage was measured by reductions in seed yield and stand and by leaf injury.

Stems And Leaves

Westag 97 has larger capacity of Cd accumulation in roots which prevents Cd from translocating into stems and leaves; conversely, AC Hime has smaller capacity of Cd accumulation in roots; more Cd is transported into stems and leaves. The different capacity of Cd in roots between Westag 97 and AC Hime causes the different Cd concentration in seeds. Meanwhile, according to the different expression levels of RSTK, ISCP, and H+-ATPase between Westag 97 and AC Hime, RSTK may be involved in transporting Cd into stems and leaves; H+-ATPase may be correlated to the capacity of Cd accumulation in roots; and Cd caused some changes of fundamental life process which leaded to the different expression patterns of ISCP between Westag 97 and AC Hime.

Herbicide Drift

There have been anecdotal accounts of increased crop sensitivity due to herbicide drift followed by an in-crop herbicide. An experiment was conducted from 2005 to 2007 at Elora, Ridgetown, and Woodstock, Ontario, to determine the effects of simulated mesotrione drift followed by in-crop applications of glyphosate, imazethapyr, bentazon and glyphosate plus chlorimuron on glyphosate-resistant soybean [Glycine max (L.) Merr.] visual injury, plant height, plant density, shoot dry weight, and seed yield. As the rate of simulated mesotrione drift increased, there was an increase in soybean injury and a decrease in shoot dry weight, height, and yield. Simulated mesotrione drift followed by bentazon resulted in synergistic responses in injury shortly after application in some environments. This increase in injury was transient, with no synergistic responses in density, shoot dry weight, and yield. In contrast, antagonistic responses were observed when glyphosate, imazethapyr, or glyphosate plus chlorimuron were applied after simulated mesotrione drift in some environments. Further research is required to develop a better understanding of the interactions of drift followed by the application of an in-crop herbicide.

Phytophthora Resistance

Four Japanese soybean (Glycine max (L) Merr.) cultivars (Fujiotome (PI 360836), Misaodaizu (PI 360839), Nezumisaya (PI 360841) and Honiku 65 (PI 360837)) were evaluated for Rps alleles conferring resistance for Phytophthora megasperma (Drechs.) f. sp. glycinea (Hildeb.) Kuan & Erwin. Fujiotome contains Rps1-a and Rps5; Misaodaizu contains Rsp1-c and Rps3; and Nezumisaya contains Rps1-b and a new allele, designated Rps? (Nezumisaya). Honiku 65 is susceptible but two variants obtained from it each contain a new Rps allele designated Rps? (OX939) and Rps? (OX940).Key words: Soybean, Phytophthora resistance
