time and duration of weed interference on yield and growth characteristics of the potato furrow and drip irrigation methods
a field experiment was conducted in research farm of isfahan university of technology, isfahan, iran in 2011 . various weeding periods were investigated on growth and yield of potato under drip tape and furrow irrigation systems. a split plot arrangement was used in a randomized complete block design with three replications. irrigation treatments were included in main plots and periods of weed ...
متن کاملPhotosynthetic Responses of Wheat, Triticum aestivum L., Plants to Simulated Insect Defoliation During Vegetative Growth and at Grain Fill
The impact of different levels of whole plant partial defoliation (WPPD) on the photosynthesis andprimarymetabolismofwheat,TriticumaestivumL.,was evaluatedat thevegetative and reproductive (grain-Þlling) developmental stages. Photosynthetic parameters such as photosynthesis, stomatal conductance, and transpiration, chlorophyll a ßuorescence, and plant morphological parameters, such asmain stemh...
متن کاملResponses of Heterodera glycines Populations to a Postemergence Herbicide Mixture and Simulated Insect Defoliation.
Effects of a mixture of the postemergence herbicides acifluorfen and bentazon, and simulated defoliation expected from green cloverworm on population densities of Heterodera glycines were determined in field plots in Iowa. The herbicide mixture and defoliation each suppressed soybean growth. Population densities of H. glycines were generally lower in herbicide-treated than untreated plots. Popu...
متن کاملResponses of Morphological Characteristics, Yield and Yield Components of Rapeseed (Brassica napus L.) as the Second Crop After Rice to Plant Density and Weed Interference Duration
In order to determine the responses of morphological characteristics, yield and yield components of rapeseed (Brassica napus L.) to plant density and weed interference duration, a factorial experiment was conducted using a randomized complete block design with 3 replications at the Rice Research Institute of Iran (RRII) in Rasht, in the 2008 growing season. The factors comprised plant density a...
متن کاملToxic Weed Seed Contaminants in Soybean Processing
Soybeans are subject to potential contamination from toxic weed seeds during harvest, transportation and storage. The more common foreign seeds include those from jimsonweed, cocklebur, nightshade, cowcockle, corncockle, morning glory, castor, pokeweed, and crotalaria. This review addresses itself to the chemistry and toxic principles of these contaminants. Since jimsonweed seeds are probably t...
