Abstract
Planting corn in one or more consecutive growing seasons in the same fields causes a yield reduction (“corn-on-corn yield penalty”). We developed methods and inoculants comprising Penicillium bilaii, to reduce corn-on-corn yield penalty. The disclosure covers the inoculants and methods for reducing corn-on-corn yield penalty.
Claims29
A method for reducing a corn-on-corn yield penalty comprising the steps of:
- a. identifying a field in need of a reduction of a corn-on-corn yield penalty, wherein said field was planted with corn in the previous growing season;
- b. applying an inoculant comprising one or more Penicillium bilaii strains to a population of corn seeds in an amount that is between 0.25 to 1 fluid ounces per hundred weight (cwt) seed;
- and
- c. planting and growing said population in said field, wherein a population of corn plants grown in said field exhibits a reduced corn-on-corn yield penalty,
- wherein representative samples of said strains having been deposited with the Northern Regional Research Laboratory (NRRL 50169, NRRL 50162, NRRL 50776, NRRL 50777, NRRL 50778, NRRL 50779, NRRL 50780, NRRL 50781, NRRL 50782, NRRL 50783, NRRL 50784, NRRL 50785, NRRL 50786, NRRL 50787, and NRRL 50788) and the American Type Culture Collection (ATCC 20851, ATCC 22348, and ATCC 18309), and wherein said applying is coating said corn seeds with said inoculant prior to said planting.

- and
- c. planting and growing said population in said field, wherein a population of corn plants grown in said field exhibits a reduced corn-on-corn yield penalty,
- wherein each of said one or more Penicillium bilaii strains has a 16S rDNA genomic sequence (16S sequence) that is at least 97% identical to a 16S sequence from a deposited Penicillium bilaii strain on the basis of 16S rDNA sequence identity, wherein said deposited strain is selected from the group consisting of ATCC 20851, NRRL 50169, ATCC 22348, ATCC 18309, NRRL 50162, NRRL 50776, NRRL 50777, NRRL 50778, NRRL 50779, NRRL 50780, NRRL 50781, NRRL 50782, NRRL 50783, NRRL 50784, NRRL 50785, NRRL 50786, NRRL 50787, NRRL 50788, and combinations thereof, and
- wherein said applying is coating said corn seeds with said inoculant prior to said planting.
