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: Dresdner scientists print tomorrow’s world

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.

The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".

Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
