Soil and crop management practices can influence CO2 emission from crop and grasslands and therefore on global warming. We examined the effects of two irrigation systems (irrigated vs. non-irrigated) and six management practices [no-till malt barley (Hordeum vulgaris L.) with 67 or 134 kg N ha (NTBFN), notill malt-barley with 0 kg N ha (NTBON), conventional-till malt barley with 67 or 134 kg N ...
Field experiments at Oakes, ND, USA in 2010 and Carrington, ND, USA in 2011 were conducted to evaluate the potential for cover crops grown in the Northern Great Plains, USA in order to reduce weed emergence and density in irrigated potatoes. Treatments included five cover crop treatments and three cover crop termination treatments. Termination of cover crops was done with glyphosate, disk-till,...
Wheat (Triticum aestivum L.) was planted as winter crop using raised bed and conventional planting system with four N levels at Regional Wheat Research Station, Rajshahi (latitude 28°75′ N and longitude 92°58′ E), during November to March in 2002 and 2003 to study N content in grain and straw, uptake of total nitrogen, N use efficiency, fertilizer recovery percentage and grain yield. The highes...
Management plan model of agricultural planting information technology research and application of design system for agricultural production and digital has important theoretical and practical significance of agricultural planting. The study concluded, extracted the relevant agricultural planting design theory and technology research based on the show, applying the system analysis principle and ...
A number of tests to study the yield response of cotton and soybean to several fertility programs, under conventional, no-till, and stale-seedbed production systems were established at the Cotton Branch Station near Marianna, Ark. Soil samples (0 to 6 inches) were collected prior to planting and extracted using the Mehlich3 procedure (extraction ratio of 1:7), with nitrate-N measured with a sel...
Zonal management of cereal–legume cover crop mixtures may help address weed and nitrogen challenges common in organic reduced tillage systems. During a field study conducted over 3 years Michigan, we evaluated the effects management, tillage, supplemental mulch on organically produced acorn squash ( Cucurbita pepo ). fall season before production, rye Secale cereale L.) vetch Vicia villosa Roth...
One of the important factors for successful agriculture is suitable planting date. For off-season cultures, we need to protect plants from adverse environmental conditions. This experiment was conducted to determine the most suitable planting date for cucumber under semi tunnel and polyethylene mulch conditions at Kaboutar-abad research station of Isfahan during two years. The experimental desi...
Hebei agricultural planting security is relative to the agricultural products of the consumer safety of the whole province and the beijing-tianjin region of. This paper selects agricultural planting safety as the research object of products and focus on the characteristics of the agricultural products plant. This paper applies theory and method of system comprehensive evaluation to screen index...
A numerical method called Multiple Attribute Decision Making (MADM) has been used for rational selection of a cotton harvester out of a finite number of cotton harvesters available the world over. In India, efforts are being made to design and develop a commercial cotton harvester to harvest selected cotton varieties sown by adopting common agronomic practices locally for cotton cultivation. Th...
