Defoliation of Sugarbeet: Effect on Root Yield and Quality

Journal of Sugarbeet Research, 2000
A three-year study was conducted to evaluate the effect of defoliation on the yield and quality of sugarbeet grown in south central Montana. Sugarbeet (Beta vulgaris L.) plants were subjected to a single defoliation of 30, 60, or 100% on six dates from July 1 through September 16 in 1991, and seven dates from June 12 and 15 through September 12 and 10 ...

Root locus for a controller class that yields cubic gain parameterization

2013 American Control Conference, 2013
We present rules for constructing the root locus for a linear feedback system, where the closed-loop denominator polynomial is quadratic in the root-locus parameter k. These quadratic root-locus rules apply to a class of controllers that are rational functions of k. We provide controller design examples to demonstrate the quadratic root locus.

Root nodule bacteria to improve yield of wheat

Plant and Soil, 1985
Beneficial effects on yield and N-assimilation in wheat cv. HD2329 due to inoculation with nine strains belonging to six species and cowpea miscellany of genus rhizobium and Azotobacter were observed. Stimulation of soil Azotobacter and Azospirillum in the root region of wheat occurred due to seed inoculation with Rhizobium.

Effect of Pachymetra Root Rot on Sugarcane Yield

Plant Disease, 1994
The effect of Pachymetra root rot on yield of sugarcane was assessed through a correlation of soil inoculum density with yield in the susceptible cultivar Q90. Variation in plot inoculum density was created by growing cultivars of varied resistance in the previous crop.

Root bacteria hack another plant hormone and affect yield

Cell Host & Microbe
Plant hormone pathways can be regulated by microbes. In a recent issue of Cell, Zhang et al. demonstrate manipulation of rice strigolactone signaling by root bacteria in field conditions and reveal the molecular mechanism of rhizosphere microbiota that affect rice tillering and yield.

Influence of nutrition on yield and quality of sugarbeet roots

1998
Zelimo li ostvariti optimalnu gnojidbu trebamo uvaziti, pored tehnicko - ekonomskih razloga, prije svega i zahtjeve šecerne repe u ishrani, kao i stanje hraniva u tlu. Danas postoje pouzdane metode za odredivanje razine pristupacnih elemenata u tlu. U radu za odredivanje zaliha hraniva korištena je EUF metoda. Pokusi su imali za cilj ispitati mogucnost
