This research aimed at investigating the effect of different levels of nitrogen and planting patterns on dry matter production and growth physiological indices in intercropping maize and sunflower. To do this a split plot experiment carried out based randomized complete block design with three replications in research field of Shushtar Islamic Azad University. The main plot included three level...

in order to evaluate the effect of nitrogen absorption and use efficiency in relay intercropping for winter wheat and maize, a field experiment was conducted during 2008-2009 at the agricultural research station of ferdowsi university of mashhad, iran. a randomized block design with three replications was used. treatments included four combinations of relay intercropping of wheat and maize (thr...

lysimeter tests were conducted on shallow groundwater that supplies part of the maize water requirements to determine crop yield. twenty-four 0.8 m diameter lysimeters were buried in the test field at a depth of 1.2 m. the lysimeters were filled with the field soil (silty loam) and planted with summer maize. the groundwater depth in the lysimeters was set at 0.6 m using marriotte bottles. three...

Abstract Photosynthetic rate and water use efficiency (WUE) are crucial for the sustainable of in agriculture. Our objective was to analyze variability photosynthetic related traits maize ( Zea mays L.) other summer crops a temperate humid area. We evaluated parameters three years compared them pigeonpea chickpea, adapted arid environments, pepper, tomato common bean, as irrigated crops. Variab...

water deficit and low nitrogen content of soil are the two major yield limiting factors in most maize (zea mays l.) producing areas. the objective of the current research was to evaluate the relationships between photosynthetic water and nitrogen use efficiency at different levels of soil moisture and nitrogen contents. a factorial experiment, based on completely randomized design with 3 replic...

Background: Maize also known as Zea mays L. is a popular crop in most of the developing countries and cultivated across world because its nutritional benefits multiple use. Bihar one major maize growing states India. An analysis production value chain will help state providing further direction for policy making. Methods: The current study explores status terms growth rate instability index bas...

The State of Veracruz (Mexico) is highly vulnerable to climate change. Therefore, it necessary identify and analyze local extreme trends explore potential relationships between indices maize. objectives this research were (1) describe recent (1979–2018) (2) compare these with maize yields produced in Veracruz, Mexico, under rainfed conditions. methodology calculated analyzed the sector-specific...

During December/January 1996/97 typical summer syndrome (hyperthermia and a 30% drop in milk yield) occurred in succession in two Holstein dairy herds (n=240 and n=150 milking cows, respectively) on the South African Highveld. These farms are situated in the midst of the prime maize and dairy farming areas of South Africa where this condition had never been diagnosed before. The individual comp...

Developing an alternative water-fertilizer-saving management practice for winter wheat-summer maize double cropping system in the North China Plain (NCP) is urgent to address severe water scarcity and adverse environmental impacts. A four-year field experiment split plot design was conducted evaluate effects of supplemental drip irrigation on grain yield, use efficiency (WUE), nitrogen (NUE), (...

for backing GM technology as it offered a means to combating hunger. The document, arising from the meeting sponsored by the academy in 2009, only emerged in the wider public domain last year. Apparently around 40 scientists, including a handful of academy members, met behind closed doors to discuss transgenic plants and food security in the context of development. The EU's new proposal suggest...
