We used a survey of attendees of an organic farming conference in Minnesota, U.S.A., to determine whether farmers would be more likely to adopt a fall-seeded winter rye cover crop preceding soybeans if doing so could aid in the suppression of soybean aphid, Aphis glycines Matsumura (Homoptera: Aphididae). Of the 24 soybean growers that responded to our survey, 22 indicated that they would be mo...

Herbicides are the major weed control tool in most cropping systems worldwide. However, the high reliance on herbicides has led to environmental issues as well as to the evolution of herbicide-resistant biotypes. Resistance is a major concern in modern agriculture and early detection of resistant biotypes is therefore crucial for its management and prevention. In this context, a timely update o...

in order to evaluation the different sowing date and different harvest time in intercropping of maize and legume plants on maize forage quality, a randomized complete block with three replications conducted in research field of university of sari agricultural sciences and natural resources in 2011. treatments were included three legume plants (soybean, fenugreek and cowpea) at two sowing time (...

In cropping systems, integrated weed management is based on diversification. Rather than relying solely on one or two herbicides, a multiplicity of weed control strategies is employed. Yet, integrated weed management as currently practiced is far from integrated; every weed is still managed the same regardless of location or season. The recent development of precision application technology is ...

Weed interference in annual cropping systems can be highly variable from year-to-year, as well as spatially heterogeneous. These factors have confounded efforts to develop simple methods for predicting competitive outcomes early in the growing season. A 2-year study was conducted with maize in competition with four annual weed species (Setaria faberi, Abutilon theophrasti, Chenopodium album and...

Four million hectares of wheat are planted after cotton and rice in Pakistan. Little research has been done on the aronomy of wheat following these crops on a cropping pattern basis. Both of these crops delay wheat planting, and it is estimated that 40–50 kg of wheat grain is lost for every day that planting is delayed past 20 November. Current recommendations for land preparation, fertilizer u...

Abstract Background Low plant density and wide intra-plant spacing in traditional cowpea cropping systems are among the factors responsible for low yield on farmers’ fields. Sole improved intercropping have been advocated last few years to increase dry savannah areas of Nigeria. This study investigated level adoption high yielding including that influenced their use perceived production constra...

In order to determine the best time use and adequate dose of four herbicides control weeds in dryland chickpea (Cicer arietinum L.) fields, we performed present experiment 4 x 5 m plots. Fourteen treatments were carried out that from 1 9 included trifluralin. Treatments 1, 2, 3 with increasing doses trifluralin (480, 720, 960 g ai ha-1) applied 30 days before planting. 4, 5, 6 15 7, 8 consisted...

Cropping systems in Western Australia (WA) are strongly dominated by cereals (wheat, barley and oaten hay) and are inextricably linked to soil quality and moisture supply. So a major research challenge is to devise cropping systems that improve soil health and maximise water-use efficiency. For a profitable and sustainable production system there is a clear need for ‘break crop’ to provide a pe...

abstract in order to evaluate the influence of nitrogen application and duration of weed interference on corn (zea mays l.) yield and yield components, a field study was conducted in 2004 at the ferdowsi university of mashhad research field. the experimental design was a randomized complete block with a factorial treatment arrangement replicated three times. nitrogen fertilizer was applied at r...
