The optimization of root nutrient content for increased sugar beet productivity using an artificial neural network

Conventional procedures are inadequate for optimizing the concentrations ofnutrients to increase the sugar yield. In this study, an artificial neural network(ANN) was used to optimize the Ca, Mg, N, K and Na content of the storage rootto increase sugar yield (Y) by increasing both sugar content (SC) and root yield(T). Data from three field experiments were used to produce a wide range ofvariati...

Root Rot Detection in Sugar Beet Using Digital Multispectral Video

A study to determine whether root rot infestations can be detected using high spatial resolution digital multispectral video (DMSV) data was conducted in the Imperial Valley of California. DMSV data were collected on two dates over 25 fields during the summer of 1999 using a light aircraft. The DMSV images included four spectral bands centered on 530 nm, 570 nm, 650 nm and 750 nm, with nominal ...

Improvement of the Sugar Beet

SUGARCANE and sugar beet are the important sources of sugar. This foodstuff, wldcli today is one of the purest and cheapest in our dietary, two centuries ago was a luxury available only to the rich. The story of the rise of sugar production to meet an ever-increasing demand is a romance of agriculture and chemistry. The accomplishments of the plant breeder and the chemical engineer in making th...

Antagonistic Activities of Trichoderma spp. on Phytophthora Root Rot of Sugar Beet

Trichoderma species are among important antagonists of plant pathogenic fungi. The main purpose of this study was to evaluate the biocontrol potential of native Trichoderma spp. isolates from sugar beet fields against Phytophthora drechsleri and P. cryptogea, the causal agents of Phytophthora root rot of sugar beet. During 2007–08, 85 isolates of Trichoderma spp. from sugar beet fields in eight...

The synthesis of sucrose by extracts of the root of the sugar beet.

There is no doubt that synthesis of sucrose does occur in the leaf of the sugar beet but the root has not previously been shown to possess a sucrosesynthesizing system. Buchanan et al. (1952) and Buchanan (1953), in photosynthetic experiments with 14CO2, demonstrated the formation of sucrose phosphate in the leaves of the sugar beet as well as of other plants. They postulated that the sucrose p...
