Vertical Distribution of Plant-parasitic Nematodes in Sandy Soil under Soybean.
Vertical distribution of five plant-parasitic nematodes was examined in two north Florida soybean fields in 1987 and 1988. Soil samples were collected from 0-15 cm, 15-30 cm, and 30-45 cm deep at each site. Soil at the three depths consisted of approximately 96% sand. More than 50% of Belonolaimus longicaudatus population densities occurred in the upper 15-cm soil layer at planting, but the spe...

15 صفحه اولGalling and Yields of Soybean Cultivars Grown in Meloidogyne arenana-Infested Soil.
Field trials with 39 soybean cultivars and five breeding lines from public and private sources were conducted from 1982 through 1985 at sites infested with Meloidogyne arenaria. Nematode population densities and root-knot galling were measured for each soybean entry. All were efficient hosts for the nematode, and average juvenile numbers in the soil increased 5-50 x from planting to harvest. Di...
متن کاملEvaluation of Soybean Cultivars for Production in Meloidogyne arenaria Race 2-Infested Soil.
Field trials with 56 soybean cultivars and breeding lines from public and private sources were conducted from 1986 through 1988 at a site infested with Meloidogyne arenaria race 2. Differences (P < 0.05) among yields were found each year and yields were negatively correlated (P < 0.01) with root-knot nematode galling. All entries were galled and the highest-yielding entries, 'Kirby' and 'Coker ...
متن کاملDiversity of Rhizosphere Soil Arbuscular Mycorrhizal Fungi in Various Soybean Cultivars under Different Continuous Cropping Regimes
Recent studies have shown that continuous cropping in soybean causes substantial changes to the microbial community in rhizosphere soil. In this study, we investigated the effects of continuous cropping for various time periods on the diversity of rhizosphere soil arbuscular mycorrhizal (AM) fungi in various soybean cultivars at the branching stage. The soybean cultivars Heinong 37 (an intermed...
