Maize Yield Potential and Density Tolerance

Crop Science, 2018
Maize (Zea mays L.) yield potential has not undergone genetic improvement during the hybrid era, yet substantial genetic improvement has occurred for tolerance to high plant population densities. As many crops including maize are approaching yield plateaus, it may be necessary to exploit other means of increasing grain yields. In this study, we examine

Increasing Yield Potential and Yield Stability in Durum Wheat

2001
In the next 20 years, it is estimated that global wheat production must increase by 40% to meet the ever increasing demand. “Increasing the intensity of production in those ecosystems that lend themselves to sustainable intensification, while decreasing intensity of production in the more fragile ecosystems” may be the only way for agriculture to keep ...

Lipid chains yield potential antibiotics

C&EN Global Enterprise, 2018
Streptomyces bacteria produce tunicamycin, a compound that shows promise as an antibiotic because it can inhibit cell-wall synthesis in other bacteria. Unfortunately, tunicamycin isn’t suitable for clinical use because it inhibits the human enzyme DPAGT1, which plays an important role in protein production.

Identities Yielding Singularity-Free Potential Integrals

IEEE Antennas and Wireless Propagation Letters, 2013
Three identities are presented that involve free-space Green's function. An eminent application of these identities is to handle the singularity problems of potential integrals in two and three dimensions. The use of identities reduces the integrals to nonsingular ones that can be calculated numerically.

Economic Potential: Reserves and Yield

Problems in Economics, 1982
Our country will enter the 1980s with a mighty economic and scientific-technical potential. Our attainments in economic and social development will permit us to tackle still weightier tasks. Fixed capital accounts for 64% of the nation's wealth. At the beginning of 1980 fixed capital amounted to 1.6 trillion rubles, i.e., it increased by 1 trillion ...

Assessing Potential Sustainable Wood Yield

2008
Society is making unprecedented demands on world forests to produce and sustain many values. Chief among them is wood supply, and concerns are rising globally about the ability of forests to meet increasing needs. Assessing this is not easy. It requires a basic understanding of the principles governing forest productivity: how wood yield varies with ...

Redox Potential and Sugarcane Yield Relationship

Transactions of the ASAE, 1980
ABSTRACT OXIDATION reduction potentials were measured using platinum electrodes to estimate soil aeration on Mhoon silty clay loam soil planted to sugarcane. Using an Eh of 332 mV as the threshold value below which reduced soil conditions may cause crop damage, the number of days that Eh was < 332 mV was determin-ed for three soil flooding durations ...

Potential wheat yields in Zambia—A simulation approach

Agricultural Systems, 1984
Abstract A simulation model is presented for the calculation of wheat yields as a function of radiation and temperature, other factors being considered non-constraining. Parametrization of the model is based on field experimentation in Zambia. The results of the model account for most of the observations obtained and it may be used therefore with ...

Potential of Using Plant Row Yield Trials to Predict Soybean Yield

Crop Science, 1999
ABSTRACTPlant row yield trials (PRYT) are measured as an indicator of yield potential for many private and public soybean breeding programs. To identify elite lines and develop new cultivars, the highest yielding PRYT lines are usually advanced to multiple replications in different environments.
