Despite weeds are a serious threat to promotion of organic farming, relatively less attention is given to research on weed management. This article explores a scope of integration of conservation agriculture for weed control and soil protection under organic farming. Limitation in the use of agro-chemicals under OF promotes intensive tillage for weed control. Mostly, tillage leads to depletion ...

abstract in order to study the effect of environmental factors (light, temperature, salinity and drought stress, acidity and burial depth) on germination and emergence of eastern dodder (cuscuta monogyna vahl), experiments were conducted at the research laboratory of faculty of agriculture, birjand university in 2009. results showed that seeds of this parasite weed had identical germination und...

to investigate the spreading possibility of spotted spurge (euphorbia maculata) as a new-introduced and troublesome weed species of soybean field in golestan province, viability of this weed seed in soil, water and elevated temperature conditions were examined. experiments were conducted as completely randomized design with eight replications. treatment levels of seed viability in soil and wate...

Parthenium hysterophorus is a weed of global significance causing great losses in India. Health challenges recorded in humans and animals are serious. Its management requires a collective approach of government and non-government agencies. Present study focuses to measure the prevalence and severity of Parthenium hysterophorus and experiments were designed to study its germination, seed dispers...

Allelopathy refers to the chemical inhibition or stimulation of one species by another which could influence on the growth or germination of other plant and used in control of weed in agricultural practices. In this sense in order to study the possibly allelopathic effects of lemon balm, bitter apple and lemon verbena medicinal plants on control of wild mustard weed, a laboratory experiment was...

the most problematic weed in summer crops in alashthar town is ground cherry (physalis divaricata). in this research, the emergence pattern of this weed in sugar beet and wheat crop was investigated during 2006- 2007. seed dormancy was also studied from october to may in two depths 0 and 10 cm, based on a factorial experiment. the results indicated that the emergence of this weed starts late ap...

a better understanding of the factors influencing the germination of weed seeds could facilitate the development of more effective cultural weed management practices. the aim of this research was to determine the effects of environmental factors on seed germination of cutleaf groundcherry (physalis angulata l.). results showed that application of gibberellic acid (ga3) was effective treatment f...

Evaluation of the viable seeds in a soil, otherwise known as the seed pool or seed bank, is a crucial component of many weed dynamic and plant ecology studies. Seed bank estimation is used to predict the possibility of future weed infestations in rangelands as well as the nascent native plant diversity within them. However, there is no standardized method of reporting seed bank evaluation techn...
