Limited water resources restrict winter wheat grain yield and quality in the Huang-Huai-Hai Plain of North China, and establishing optimal planting patterns according to crop water requirements is the key factor for achieving rational water use. In this paper, 4 planting patterns were applied, namely, uniform row (30 cm; traditional pattern), wide (40 cm)-narrow (20 cm) row, furrow (double line...
A suitable planting pattern and irrigation strategy are essential for optimizing winter wheat yield and water use efficiency (WUE). The study aimed to evaluate the impact of planting pattern and irrigation frequency on grain yield and WUE of winter wheat. During the 2013-2014 and 2014-2015 winter wheat growing seasons in the North China Plain, the effects of planting patterns and irrigation fre...
Background & aim: Saline lands can be utilized by planting native medicinal plants tolerant to salinity. The quantity and quality these plants are changed during various seasons in agriculture systems. Thus, this study carried out under salinity stress in order to examine the effect of sowing in two seasons on growth characteristics and essential oil components of ajowan (Carum capticum </...
Studying the distribution of Zn in the soils allows investigating their mobility and bioavailability. In this research, 10 calcareous soil samples were selected, and sewage sludge-amended (1% w/w) and -unamended (control) soils were incubated for 1 month. Before planting, fractions of Zn were determined, three seeds of wheat were planted in each pot and after 8 weeks, they were harvested. Resul...
Results We present global planting date patterns for maize, spring wheat and winter wheat (our full, publicly available data set contains planting and harvesting dates for 19 major crops). Maize planting in the northern mid-latitudes generally occurs in April and May. Daily average air temperatures are usually c. 12–17 °C at the time of maize planting in these regions, although soil moisture of...
South Africa has been described as a melting pot of different cultures, adding to the rich South African heritage, boasting eleven official languages. This cultural diversity, however, poses quite a unique challenge for designers of software, especially in the design of e-commerce websites. This paper describes an experiment with the net-generation and the effects of culture on users’ perceptio...
Strip-till has been used at a large scale in east central Kansas as an alternative to earlier planting dates under a no-till system. To determine the effects of planting corn (Zea mays) under previously established strip-tilled fertilized rows, experiments were conducted on an Osage silty clay loam soil in 2006 and 2008 and on a Woodson silt loam soil in 2009, 2010, and 2011 using three differe...
پتاسیم قابل استفاده در خاک معیار مهمی برای رشد گیاه و تولید عملکرد است. برخی باکتری های خاک می توانند پتاسیم قابل استفاده را برای رشد گیاهانافزایش دهند. به منظور جداسازی و بررسی میزان کارایی این باکتری ها در خاک، تعداد پنج نمونه خاک از نظر وجود باکتری های آزاد کننده پتاسیم مورد ارزیابی قرار گرفتند و در نهایت شش ایزوله به عنوان باکتری های موثر، جداسازی شدند. براساس بررسی های میکروسکوپی، آزمون ها...
Corn (&a mays L.) growth has been shown to be affected by planting date and amount of residue on the soil surface. The objective of this study was to determine if the adverse effects of cool soil temperatures on early seedling growth often associated with surface residues can be overcome by planting at later dates. Corn was planted at several planting dates (late April through early June) into ...
Three studies in the Coastal Plain of Georgia were remeasured 7 or 8 years after planting to determine the effects of planting depth on field performance of open-rooted seedlings [root-collar diameter (RCD) ≥ 5 mm]. Average planting depth (i.e. shoot height before planting minus shoot height above ground after planting) for machine planted P. elliottii was 14 cm while hand-planted P. taeda seed...
