The host suitability to Ditylenchus destructor of seven common weed species in peanut (Arachis hypogaea) fields in South Africa was determined. Based on the number of nematodes per root unit, white goosefoot (Chenopodium album), feathertop chloris (Chloris virgata), purple nutsedge (Cyperus rotundus), jimson weed (Datura stramonium), goose grass (Eleusine indica), khaki weed (Tagetes minuta), a...

Field experiment was conducted at KPK Agricultural University, Peshawar, Pakistan to find out the effect of planting methods on the yield and yield components of maize varieties. Analysis of the data revealed that planting methods had a significant effect on days to tasseling, days to silking, plant height, number of plants ha at harvest, thousand grain weight, grain yield, biological yield, fr...

in order to investigate the effects of weeds interference on yield and yield components of different genotypes of common bean, an experiment was conducted as split plot based on randomized complete block design with three replications at agricultural research station of tabriz university, in 2011. the main plots were eight genotypes of different types of common bean including red bean, (cv. gho...

in order to study of the effect of nitrogen source, operation method and weed control methods on weed biomass, yield and yield components of corn (zea mays l.) an experiment was carried out as split plot factorial based on randomized complete block design (rcbd) with four replications in shahrood university of technology. the treatments included weed control methods at four levels (hand weeding...

Important roles for biotic agents in integrated weed management include preventing seed production and weed emergence from the seed bank. Seed-attacking microorganisms have been described for a limited number of economically important weeds and serve as examples illustrating the potential for reducing weed seed production. Innundative releases of seed-feeding insects have also successfully redu...

The host suitability of five of the most common weed species occurring in maize (Zea mays L.) fields in South Africa to Pratylenchus zeae was tested. Based on the number of nematodes per root unit, mealie crotalaria (Crotalaria sphaerocarpa) was a good host; goose grass (Eleusine indica), common pigweed (Amaranthus hybridus), and thorn apple (Datura stramonium) were moderate hosts; and khaki we...

In order to study the effects of wild mustard competition and different levels of nitrogen on effective traits of wheat yield, this research was conducted in Ahvaz, south west of Iran. The study was consisted of a split plot experiment, on the basis of Randomized Complete Blocks Design with three replications. Different levels of nitrogen (90, 150 and 210 kgN.ha-1) were assigned in the main plo...

Weed management is critical in hazelnut (Corylus avellana) production. Weeds reduce nutrient availability, interfere with tree growth, and reduce handharvesting efficiency. Field experiments were conducted from Fall 2006 to 2010 to test effects of brassica (Brassica sp.) cover crops and hazelnut husk mulch as alternative weed management strategies in hazelnut. The cover crop treatments consiste...

Unconventional ways of growing plants, when we return to non-chemical methods of controlling weeds, require new weed control methods. One of the few physical methods, which found wider application in practice, is a flame weeder with heat burners based on the use of gas (LPG). However, the process of practical use of this flame weeder has a number of factors that positively or negatively affect ...

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 ...
