Due to expansion of urbanization, introduction of advanced technology in the agriculture systems and low returns in traditional farming systems, farmers of the Central Development Region of Nepal were compelled to change the traditional farming systems to modern systems. The present study aims to find out the factors that affected the changes in cropping patterns in hills and plains of this reg...

This study evaluated microbial communities of soil (0–10 cm) as affected by dryland cropping systems under different tillage practices after 5 years. The soil type was an Olton sandy loam with an average of 16.4% clay, 67.6% sand and 0.65 g kg of organic matter (OM). The cropping systems evaluated were grain sorghum (Sorghum bicolor L.)— cotton (Gossypium hirsutum) (Srg-Ct), cotton-winter rye (...

ABSTRACT Eight different 3-year cropping systems, consisting of soybean-canola, soybean-barley, sweet corn-canola, sweet corn-soybean, green bean-sweet corn, canola-sweet corn, barley-clover, and continuous potato (non-rotation control) followed by potato as the third crop in all systems, were established in replicated field plots with two rotation entry points in Presque Isle, ME, in 1998. Cro...

Belonolaimus longicaudatus has been reported as damaging both potato (Solanum tuberosum) and cotton (Gossypium hirsutum). These crops are not normally grown in cropping systems together in areas where the soil is infested with B. longicaudatus. During the 1990s cotton was grown in a potato production region that was a suitable habitat for B. longicaudatus. It was not known how integrating the p...

Fusarium head blight is one of the most important cereal diseases worldwide. Cereals differ in terms of the main occurring Fusarium species and the infection is influenced by various factors, such as weather and cropping measures. Little is known about Fusarium species in barley in Switzerland, hence harvest samples from growers were collected in 2013 and 2014, along with information on respect...

In conventional electronic video stabilization, the stabilized frame is obtained by cropping the input frame to cancel camera shake. While a small cropping size results in strong stabilization, it does not provide us satisfactory results from the viewpoint of image quality, because it narrows the angle of view. By fusing several frames, we can effectively expand the area of input frames, and ac...

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...

Rice-wheat production is an essential component of cropping systems in the Indus-Ganga Plains (IGP) which play a pivotal role food security south Asia. These crops are being cultivated on area about 13.5 M ha South In rice-wheat system, major reason for lower wheat grain yield use unwise tillage practices during seedbed preparation, cultivation late maturing rice varieties, water shortage, labo...
