Effects of soil condition and burial on boll weevil, Anthonomus grandis grandis Boheman, mortality in fallen cotton, Gossypium hirsutum L., fruit were assessed in this study. During hot weather immediately after summer harvest operations in the Lower Rio Grande Valley of Texas, burial of infested fruit in conventionally tilled field plots permitted significantly greater survival of weevils than...

paddy rice residue covers more than 60000 ha of the khuzestan plain. high soil moisture content (low evaporation and heavy soil texture), time limitations, and the likelihood of rainfall make conventional tillage methods unsuitable for wheat cultivation after the rice harvest. the present study investigated the best residue management method, and fuel and time savings, to produce acceptable yie...

Tillage may in ̄uence nitrate losses from agricultural soils. Losses of nitrate were measured in drain ̄ow at 60 cm depth and in combined surface runoff and inter ̄ow in the A horizon (ˆsurface layer ̄ow) on hydrologically sealed plots with a two-year comparison (1988±1990) of shallow-tine cultivation vs. mouldboard ploughing. Ploughing increased concentrations and loadings of nitrate in drain ̄ow ...

the effects of soil tillage methods and residue management were studied at miandoab agriculure station during 2003-2005. the experiment design was split block with the main plots devoted to residual management strategies (burning residue, crushing residue by disk, no treatment). subplots were tillage methods (moldboard plowing to 20-25 cm in fall, moldboard plowing to 20-25 cm in spring, moldbo...

We can overcome this global challenge by minimizing input costs and optimizing yields employing appropriate tillage techniques balanced fertilizer application. Appropriate practices together with may be a promising practice of soil management to improve properties crop production. The present study was carried out in wheat-maize cropping pattern (in the year 2019-20) at agricultural research fa...

In order to evaluate effect of planting date and plant density on grain yield, yield components and some quality and morphological traits of chickpea (Cicer arietinum L.), an experiment was conducted at the research center of agricultural and natural resources of west Azerbaijan in Urmia rain-fed research farm during 2005-2006 growing season in a split plot arrangement, based on a completely ra...

We determined the effects of crop residue on the persistence of an entomopathogenic nematode, Steinernema carpocapsae. During 2 consecutive years, nematodes were applied at rates of 2.5 x 10 and 1.0 x 10 infective juveniles/m(2) to small field plots planted with corn. Nematode persistence was monitored by exposing Galleria mellonella larvae to soil samples from plots with and without crop resid...

drought stress is the most important factor that reduces yield in crops including chickpea and causes some changes in seed composition. this study was performed in order to evaluate the effects of drought stress and starter nitrogen fertilizer on four cultivars of chickpea. experiment was performed in a split-factorial using randomized complete block design with three replications. drought stre...

We evaluated the eff ects of irrigated crop management practices on nitrous oxide (N2O) emissions from soil. Emissions were monitored from several irrigated cropping systems receiving N fertilizer rates ranging from 0 to 246 kg N ha−1 during the 2005 and 2006 growing seasons. Cropping systems included conventional-till (CT) continuous corn (Zea mays L.), no-till (NT) continuous corn, NT corn–dr...
