Hebrew University Research Brings Higher Peanut Yields

01.04.2003


Significantly improved peanut yields have been achieved by researchers at the Hebrew University Faculty of Agricultural, Food and Environmental Sciences in Rehovot.

Through the use of the plant hormone ethylene, the researchers have succeeded in regulating the flowering of the peanut plant, with a resulting four-fold increase in the yield of large peanut pods at harvest time.

The research was carried out by Eliezer Zamski, the Jack Futterman Professor of Agricultural Botany at the Institute of Plant Sciences and Genetics in Agriculture at the Hebrew University, together with Zvi Bar of the Center for Research, Development and Training of the Maon District and Oran Bochshtav of Kibbutz Nirim.


Peanuts (Arachis hypogaea) are rich in protein and are an important product for man and industry. In Israel, some 33,000 dunams (8250acres) are devoted to peanut farming in the western Negev, the Sharon and the Galilee. The average yield is 500-600 kilograms per dunam. The period of growth is from 145-175 days, commencing in April.

Every peanut plant produces more than 400 flowers during the growth period, but in the end only about 35 of them ripen into peanut pods that are large enough to bring a top return on the market. In cash terms, the larger peanut pods (super giant) bring a return on the export market of $1,550 a ton, while the smaller peanuts (extra fancy) bring only about $1,100 a ton. Hence, regulating growth so that four times as many of the pods reach optimal market size – as has been achieved by Prof. Zamski and his associates -- has significant consequences for the farmer.

Im Focus: First evidence on the source of extragalactic particles

For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.

To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...

Im Focus: Magnetic vortices: Two independent magnetic skyrmion phases discovered in a single material

For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.

Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...

Im Focus: Breaking the bond: To take part or not?

Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.

A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...

Im Focus: New 2D Spectroscopy Methods

Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.

"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....

Im Focus: Chemical reactions in the light of ultrashort X-ray pulses from free-electron lasers

Ultra-short, high-intensity X-ray flashes open the door to the foundations of chemical reactions. Free-electron lasers generate these kinds of pulses, but there is a catch: the pulses vary in duration and energy. An international research team has now presented a solution: Using a ring of 16 detectors and a circularly polarized laser beam, they can determine both factors with attosecond accuracy.

Free-electron lasers (FELs) generate extremely short and intense X-ray flashes. Researchers can use these flashes to resolve structures with diameters on the...
