Effects of Potato Leafhoppers on Soybean Plant Growth and Yield
Various densities of adult potato leafhoppers were established on 'Essex' soybean at plant growth stage V2 in caged field plots. Cages were removed two weeks later, and plots remained uncaged for the rest of the growing season. Direct counts of nymphal leafhoppers on plants shortly after cage removal confirmed that a gradient of infestation levels was attained. In both years of the study, highe...
متن کاملFetal Growth Curve in Neonates in Alzahra Hospital in Rasht
ABSTRACT Evaluation of intrauterine growth and determination of at risk neonates was done by weight criteria for each pregnancy age. This criteria in different populations is not similar. Main objective of this study was determination of intrauterine growth pattern in this region. Weights of 2380 term neonates and 788 preterm neonates that had a definite LMP and were born at Alzahra hospital i...
متن کاملgrowth and yield response to different nitrogen levels potato plant
this experiment was conducted in andimeshk region (north of khouzestan) to study the effects of nitrogen levels on plant characters of two potato cultivars (solanum tuberosum l.) in identical conditions of poultry manure, in 2012-2013 crop year, as a factorial randmaized complete block design with three replications. the first factor was consisting of four nitrogen levels (0, 70,140 and 210 kg...
متن کاملPlant pathogen population dynamics in potato fields.
Modern technologies incorporating Geographic Information Systems (GIS), Global Positioning Systems (GPS), remote sensing, and geostatistics provide unique opportunities to advance ecological understanding of pests across a landscape. Increased knowledge of the population dynamics of plant pathogens will promote management strategies, such as site-specific management, and cultural practices mini...
متن کاملPlant-mediated gene silencing restricts growth of the potato late blight pathogen Phytophthora infestans
Phytophthora infestans is an oomycete that causes severe damage to potato, and is well known for its ability to evolve rapidly in order to overcome resistant potato varieties. An RNA silencing strategy was evaluated here to clarify if small interfering RNA homologous to selected genes in P. infestans could be targeted from the plant host to reduce the magnitude of the infection. As a proof-of-c...
