Compared with a monoculture planting mode, the practice of crop rotations improves fertilizer efficiency and increases yield. Large-scale rotation monitoring relies on results classification using remote sensing technology. However, limited accuracy cannot satisfy accurate identification patterns. In this paper, mapping scheme combining random forest (RF) algorithm new statistical features extr...

rotation is also more effective in preventing deep leaching of nitrate N than continuous corn (Katupitiya et al., Reduced tillage, including no-till, and crop rotation are common 1997; Varvel and Peterson, 1990). Reduced stress from practices for corn (Zea mays L.) and soybean [Glycine max (L.) Merr.] production in the Midwest. Benefits of no-till vary with latitude pests may be one of the reas...

The interaction between millet and European corn borer, Ostrinia nubilalis (Hübner), was investigated to gain insight into whether millet could serve as a refuge or trap crop for O. nubilalis management. In 1995, 1996, and 1999, millet selection studies were conducted in North Dakota and New York with four millet species. Proso millet, Panicum milliaceum L., had the highest infestation and wide...

BACKGROUND Larval movement of target pest populations among Bt and non-Bt plants is a major concern in the use of a seed mixture refuge strategy for Bt resistance management. In this study, occurrence and larval movement of the sugarcane borer, Diatraea saccharalis (F.), were evaluated in four planting patterns of non-Bt and Bt plants containing Genuity® SmartStax(TM) traits in 2009-2011. The f...

The aim of the research was to find out pattern corn agricultural processing activities that were consistent or not carried by farmers and impact process in Gorontalo Regency..The data collection method used a questionnaire, sample this study Regency Corn Farmers Association (GAPOKTAN) which determined using slovin formula with an estimation error 10%. collecting on uses Proportional Random mod...

Beef and dairy industries form the base of livestock production in New Mexico. In 2003, Curry, Roosevelt, and Chaves counties accounted for over 48% of all livestock cash receipts in the state (New Mexico Agricultural Statistics, 2003). Milk is the state’s number one cash commodity, producing over $790 million in 2003; and these three counties accounted for over 63% of milk cow numbers and milk...

Incidence of insect damage, and association of insect damage with mycotoxigenic corn ear molds and mycotoxins was examined in commercial fields of Bt and non-Bt hybrids of different backgrounds in Illinois in 1998 and 1999. Nearly 50% Helicoverpa zea (Boddie) infestation sometimes occurred in Bt hybrids that express high levels of the protein in silks and kernels. Damage by European corn borer,...

Root-knot nematodes, particularly Meloidogynejavanica (Treub.) Chitwood, 1949 and M. incognita (Kofoid and White) Chitwood, 1949, are among the most important pathogens of carrots (Daucus carota L.) in Brazil. They damage tap roots by galling, digitation, and constriction, resulting in lower market value (3). Even low soil densities of root-knot nematodes have been reported to reduce marketable...

Corn (Zea mays L.) is one of the most sensitive crops to planting pattern and early-season uniformity. The most common method to determine number of plants is by visual inspection on the ground but this field activity becomes time-consuming, labor-intensive, biased, and may lead to less profitable decisions by farmers. The objective of this study was to develop a reliable, timely, and unbiased ...
