Population Dynamics of Plant-parasitic Nematodes on Cover Crops of Corn and Sorghum.

Buildup of plant-parasitic nematode populations on corn (Zea mays), soybean (Glycine max), and sorghum (Sorghum bicolor) were compared in 1991 and 1992. Final population densities (Pf) of Meloidogyne incognita were lower following sorghum than after soybean in both seasons, and Pf after sorghum was lower than Pf after corn in 1992. In both seasons, Pf differed among the sorghum cultivars used. ...

Effect of watering regimen on injury to corn and grain sorghum by pratylenchus species.

The effect of simulated rainfall frequency on the pathogenicity of Pratylenchus zeae and P. brachyurus was studied in four greenhouse experiments. Corn and grain sorghum were watered at different intervals during predetermined cycles to create a gradient of water-stressed plants. Each experiment included nematode and uninoculated treatments. Growth reaction of plants to different frequencies of...

Reduced Height (Rht) Alleles Affect Wheat Grain Quality

The effects of dwarfing alleles (reduced height, Rht) in near isogenic lines on wheat grain quality are characterised in field experiments and related to effects on crop height, grain yield and GA-sensitivity. Alleles included those that conferred GA-insensitivity (Rht-B1b, Rht-B1c, Rht-D1b, Rht-D1c) as well as those that retained GA-sensitivity (rht(tall), Rht8, Rht8 + Ppd-D1a, Rht12). Full ch...

Effect of Corn, Sugarbeets, and Fallow on Zinc Availability to Subsequent Crops

Field observations indicated that Zn deficiency of beans (Plasscoins melons L.) was sometimes more severe than expected when grown on Mowed soil that was low to marginal in available Zn. The objectives of this study were to determine the effects of fallow, suprbeets (Beta Moods L.), and corn (Zea mays L.) on Zri availability to subsequent crops grown on a Portneuf silt loam (Durixerollic Calcio...
