Yield Technologies

  • agronomy
    • farmer production education
    • investment capital
    • precision application
    • no-till (with herbicide tolerance)
  • genetic improvement
    • edaphic stress
    • metabolic efficiency

Farmer Production Education

In addition to basic farming expertise, any technology advancement requires adjustments to entire production system.

e.g. Introduction of high priced

Bt-cotton seed to eastern China:

  • lower seeding rates
  • disease susceptible foreign

variety

  • yield boost caused K

deficiencies

  • 2° pests no longer controlled

Supplemental irrigation raises Water Use Efficiency in rainfed cotton but requires investment in water delivery systems

Fiber Yield (lbs/acre)

Investment Capital

slide5

Optimum agronomic management:

1970’s farm scale recipe

  • 1990’s field scale
  • 2000’s soil type scale
  • 2010’s 10 m2 scale

fiber yield

total nitrogen

Precision Application

slide6

apply inputs as needed

minimize stress and evaporation

preserve rainfall & soil

Breeding further narrowed germplasm

Genetic Diversity Lost

Plants are immobile so evolved to tolerate stress.

DNA tools allow breeding with wild cotton for soil borne stresses:

  • - nematodes
  • - diseases
  • - drought

Genetic Diversity Regained

Plants are immobile so evolved to tolerate stress.

DNA tools allow breeding with wild cotton for soil borne stress:

  • nematodes,
  • diseases,
  • drought

In addition to the multiple breeding tools, we could reach back in time to the rapid evolution of the fiber and make it better the 2nd time around.

Biotech adopters benefit from all the ancillary benefits of a robust, professional local seed industry PLUS the trait.

their potential to raise production
& their potential to raise production

Raise Production

  • China
  • India
  • USA
  • Africa
slide14

Climate Disruption creates uncertainty as to how well India benefits from yield technology. Seed has had a huge impact: - Bt-cotton insect control- locally adapted hybrids Anticipate future seed benefits:- no-till facilitated by glyphosate herbicide tolerance.- higher stand density facilitated by lower cost hybrid seed production and apomixis hybrids

India

slide15

Water supply limitations are not solved with drought tolerance. Western China adopting USA production system. Eastern China likely not, maybe no-till with Herbicide Tolerance

Nature (2010) 467:43-51

China

slide16

As the first adopter of USA-centric innovations we will benefit greatly, IF their development is funded. Supplemental irrigation in the rainbelt is expanding rapidly but West Texas water supply is uncertain.

USA

slide17

The modal fertilizer rate in Africa is Zero!

Slight improvement in input resources, infrastructure and education would have a dramatic impact on African cotton yields.

Africa

slide18

Optimistic that cotton yield gains can satisfy some of the expanding global demand for textile fiber.
