Effects of subsoiling and nematicides on Hoplolaimus columbus populations and cotton yield.

R S Hussey PubMed 1977

Other claims from this paper (7)

Intervention effect Three years of subsoiling increased annual seed cotton yields by 50 to 200%.
Intervention effect DBCP reduced Hoplolaimus columbus populations.
Intervention effect Aldicarb reduced Hoplolaimus columbus populations.
Intervention effect DBCP did not increase seed cotton yields over subsoiling alone.
Intervention effect Aldicarb did not increase seed cotton yields over subsoiling alone.
Intervention effect Subsoiling reduced H. columbus in the top 20 cm of soil.
Mechanism Subsoiling favored deeper cotton root penetration and less upper soil root colonization by H. columbus.

Other claims from this paper (6)

Intervention effect Applying Pseudomonas putida 23 increased red beet yield in soils with minimum nitrogen fixation and high bacterial survival.
Intervention effect Applying the bacterium did not improve yield where nitrogen fixation was maximal and bacterial survival low.
Intervention effect Bacterium application did not increase yield in those high nitrogen fixation soils.
Intervention effect In low nitrogen fixation soils, bacterium application increased nitrogen fixation activity.
Observation The yield gain in low nitrogen fixation soils remained below the maximum yield level.
Recommendation The authors propose soil nitrogen fixation activity as a test for predicting bacterial application effectiveness.
