Soybean seeds and cotyledons suffer great damage by the Rufous Turtle Dove in Japan, depending upon the time of seed sowing. In our experimental field at Tsukuba, in 1983, almost all plants were eaten until the middle of May. Doves concentrated in fields where soybean seeds had been planted from the late April to the middle of May. After the middle of May, they came to the fields where wheat an...

During the spring and summer of 1986, I studied the distribution and breeding biology of five rare birds in the Oklahoma Panhandle: Ferruginous Hawk (Hrrtcv regalis), Golden Engle (Aquiln cht-pctos), Prairie Falcon (Fnlco incsicn~rzrs), Mountain Plover (Clmradrirrs nzontnirrrs) and Long-billed Curlew (N~rinriiirrs ainrricn~iris). Longbilled Curlewsare regular migrants through the western half o...

abstract conservation tillage practices integrated with appropriate residue management is an efficient approach in sustainable agriculture to prevent the removal or burning of crop residues. two years field experiments were conducted to evaluate the effect of wheat residue management on yield, yield component and morphophysiological characteristics of corn. experimental design was split plot us...

Abstract In the soft red winter wheat ( Triticum aestivum L.) growing regions of eastern United States, midwinter warm temperatures have accelerated development, exposing that has transitioned to reproductive stages cold during late spring. The objectives this diagnostic guide were to: (a) provide images depicting freeze injury and (b) estimates grain yield straw biomass reduction in response l...

weeds in wheat (triticum aestivum l.) fields have always been a big problem in iran and worldwide and must be managed by non-chemical especially cultural methods. a field experiment as factorial based on a randomized complete block design with four replications in a 1000 m2 field in research farm of shirvan college of agriculture was conducted during 2007-2008. treatments included wheat densiti...
