Influence of development stage of spring oilseed rape and spring
10 The dry and wet deposition of radionuclides released into the atmosphere can be 11 intercepted by vegetation in terrestrial ecosystems. The aim of this study was to quantify the 12 interception of wet deposited Cs and Sr by spring oilseed rape (Brassíca napus L.) and 13 spring wheat (Tríticum aestívum L.). The dependency of the intercepted fraction (f) on total 14 above ground plant biomass,...
متن کاملInterrelationships among oilseed rape (Brassica napus L.) grain yield and weed growth under different nitrogen levels
Management of nitrogen fertilization in crops is one of the most important components of integrated weed management. A two-year field experiment was conducted to determine the direct effects of wild mustard aboveground biomass and N content of wild mustard on oilseed rape yield. A set of factorial treatments was arranged in a randomized complete block design with four replications. Treatments w...
متن کاملSeed dressings to control slug damage in oilseed rape.
Slugs are major pests of oilseed rape that are poorly controlled by conventional bait pellets. A series of laboratory experiments investigated the potential of seed-dressings to control slug damage in this crop. Four compounds: metaldehyde, methiocarb, cinnamamide and 3,5-dimethoxycinnamic acid (DMCA) were tested at a range of doses for phytotoxicity and ability to reduce damage by Deroceras re...
متن کاملWeed Control Effi cacy of Organic Mulches in Two Organically Managed Bell Pepper Production Systems
A 2-year field study in Lexington, Ky., evaluated weed control efficacy and infl uence on yields of several organic mulches in two organically managed bell pepper (Capsicum annuum) production systems. Five weed control treatments [straw, compost, wood chips, undersown white dutch clover (Trifolium repens) “living mulch,” and the organically approved herbicide corn gluten] were applied to two pr...
متن کاملHybridization and backcrossing between transgenic oilseed rape and two related weed species under field conditions.
Determining the frequency of crop-wild transgene flow under field conditions is a necessity for the development of regulatory strategies to manage transgenic hybrids. Gene flow of green fluorescent protein (GFP) and Bacillus thuringiensis (Bt) transgenes was quantified in three field experiments using eleven independent transformed Brassica napus L. lines and the wild relatives, B. rapa L. and ...
