In the article are presented investigation results, which shows effectiveness of urea with urease inhibitor – nBPT in potato growing agroecosystems. The advantages new fertilizer yield increase, and quality improvement. Urea lead to formation bigger tuber size what is one most important characteristic for marketable potato. Fertilizer was tested experimental fields real farm conditions.
Breeding for improved crop quality traits can affect non-target traits related to growth and resource use, and these effects may vary in different cultivation conditions (e. g., greenhouse vs. field). The objectives of this study are to investigate the growth and whole-plant nitrogen (N) economy of two genetically modified (GM) potato lines compared to their non-GM parental varieties and when g...
From 1995 through 2001, genetically modified potatoes were sold in the United States and Canada under the brand name NewLeafTM. These potato varieties were relatively popular with growers because they replaced pest-control practices involving intensive use of pesticides with technology that was present in the potato seed. Market tests indicated that the concept of reduced pesticide use through ...
colonies was white to gray, and the reverse was colored pale yellowish brown. The strain produced no reproductive structures even on sterilized natural substrates. The absence of morphological characteristics implied that this fungus could be treated as a deuteromycete in the Agonomycetes3). YM-170320 (1) was produced by solid state fermentation. Vegetative mycelia of strain YL-03706F growing o...
Actinomycests are soil habitant which among them Streptomyces are plant pathogens. They were isolated from potato scab lesion complex collected from crop growing area. Pathogenicity on mini-tuber and plants were done and they were tested for: the presence of nec1 gene, diversity and differences in disease severity induction. Results indicated that most of the strains harbor nec1 and they were b...
Traditional farming practices suggest that cultivation of a mixture of crop species in the same field through temporal and spatial management may be advantageous in boosting yields and preventing disease, but evidence from large-scale field testing is limited. Increasing crop diversity through intercropping addresses the problem of increasing land utilization and crop productivity. In collabora...
Experiments were conducted to determine whether the beet leafhopper, Circulifer tenellus (Baker) (Hemiptera: Cicadellidae), transmits the purple top phytoplasma to potato, Solanum tuberosum L.; beets, Beta vulgaris L.; and selected weed hosts. The beet leafhopper-transmitted virescence agent (BLTVA) phytoplasma was identified as the causal agent of the potato purple top disease outbreaks that r...
The potato psyllid, Bactericera cockerelli (Sulc) (Hemiptera: Triozidae), is a pest of potato and other solanaceous crops in North and Central America and New Zealand. Previous genotyping studies have demonstrated the presence of three different haplotypes of B. cockerelli in the United States corresponding to three geographical regions: Central, Western, and Northwestern. These studies utilize...
An experiment was conducted to evaluate the effects of a restriction to home-grown feedstuffs and abstinence from supplementation with synthetic amino acids (AA), as ideal objectives in organic pig production according to the IFOAM standards, on growth performance and carcass characteristics. One hundred individually housed pigs were allocated to four dietary treatments and fed from growing thr...
A line source sprinkler was used to irrigate corn (Zen ?nays L.) plots with potato (Soianum tuberosum L.)-processing wastewater in 1979, 1980, and 1981. Nitrogen applications ranged from about 4 to 600 kg/ha. Corn yields were measured for each row, the grain and stalks were analyzed for total N, and N uptake was calculated. The plots were split by years, one-third of the area was fertilized wit...
