Effects of sowing time and rate on crop growth and radiation use efficiency of winter wheat in the North China Plain
Crop depends on its canopy to intercept solar radiation to drive both assimilation and water, nutrient absorption for its growth. Field experiments, involving three sowing time and three sowing rate, were conducted at Luancheng Station to investigate the effects of canopy size and development on crop growth and radiation use efficiency (RUE) of winter wheat during 2009/2010 and 2010/2011 gr...
متن کاملChanges in weed seed banks and the potato yield as affected by different amounts of nitrogen and crop residue
In order to evaluate the impact of crop residues (zero, 25 and 50%) and nitrogen (zero, 125 and 250 kg ha) on weed seed bank and potato yield, two-years research was conducted as a split plot arranged in randomized complete block design in Rozveh Agriculture Research Station, Freidan-Esfahan. Numbers of weed species in seed bank, aboveground, and both seed bank and aboveground were 1, 2 and...

increasing attention has recently been given to sweet sorghum as a renewable raw material for ethanol production, mainly because its cultivation can be fully mechanized. however, the intensive use of agricultural machinery causes soil structural degradation, especially when performed under inadequate conditions of soil moisture. the aims of this study were to evaluate the physical quality of a ...
متن کاملStock Quality of Black Walnut (Juglans Nigra) Seedlings as Affected by Half-Sib Seed Source and Nursery Sowing Density
Morphological quality of black walnut (Juglans nigra L.) seedlings largely dictates their capacity to establish well in plantations and their performance potential for use as rootstocks in grafting. Larger seedlings and rootstocks, attained from propagation at relatively low nursery sowing densities, have comparatively more expansive root systems for exploitation of soil resources and greater n...
متن کاملLiver cytochrome P450 system as affected by endophyte-infected tall fescue seed extracts and ergot alkaloids
Endophyte infected tall fescue (E+) is the base diet for nearly all beef cattle in the southern USA. It has been linked to a variety of toxicological conditions due to the presence of large numbers of ergot alkaloids. This study was designed to investigate the effects of E+ seed extract and selected ergot alkaloids on the detoxification pathway by cytochrome P450 (CYP3A4) enzyme system. Tests w...
