Higher prices for hardwood stumpage and changes in agricultural policies may favor afforestation on sites in the Lower Mississippi Alluvial Valley (LMAV) which are suitable for Eastern cottonwood (Popu/us de/toides Bartr.). We examined the potential returns to a landowner growing cottonwood on three soil classes common to the LMAV. We specified the conditions under which we think such afforesta...

to evaluate the effect of row spacing and seed rate on grain yield and agronomical traits of common bean cultivars, a split factorial experiment based on the complete randomized block design with three replications was conducted at rice research institute of iran (rasht) in 2008 and 2009 cropping years. experimental treatments were row spacing in three levels of 20, 30 and 40 cm as main plot an...

A field trial was conducted for 2 years in an Arredondo fine sand containing a tillage pan at 15-20 cm deep to determine the influence of subsoiling on the distribution of corn roots and plant-parasitic nematodes. Soil samples were taken at various depths and row positions at 30, 60, and 90 days after planting in field corn subsoiled under the row with two chisels and in non-subsoiled corn. At ...

Bio-economic efficiency of different cotton-based intercropping systems was determined at the Agronomic Research Area, University of Agriculture, Faisalabad, (Pakistan) during 1996-97 and 1997-98. Cotton cultivar NIAB-78 was planted in 80-cm apart single rows and 120-cm spaced double row strips with the help of a single row hand drill. Intercropping systems were cotton alone, and cotton + mungb...

in order to study the effects of planting pattern on yield and yield components in different cultivars of forage corn (zea mays l.), an experiment was conducted at saline conditions (ec=6.43 ds.m-1) of dasht-e-malhe, neyshabour during growing season of 2009-2010. nine treatments and two furrow planting and furrow bed planting as main plots and three cultivars (ksc 704, zp 644 and ns540) as sub ...

A recently completed (Nov. 2009), Cornell University project that focused on controlling weeds in strawberries during the establishment year by transplanting dormant berry plants into a killed cover crop showed great promise, but revealed a barrier. Most growers had difficulty planting through the cover crop. This resulted in slower establishment during the first month and possibly caused skips...

The crop chosen for this study is chickpea (Cicer arietinum L.) as the fourth most important legume in Australian agriculture (FAOSTAT 2004). One of the major obstacles in growing this crop is its poor competitive ability with weeds, which leads to significant reductions in yield. The best method to control weeds in crops such as chickpea is through the use of integrated weed management (IWM). ...

Abstract Alternative strategies are needed for management of glyphosate-resistant (GR) horseweed in soybean. Integrating a cereal rye cover crop with soybean planted narrow rows may improve control and reduce herbicide selection pressure herbicide-resistant biotypes. Four site-years experiments were conducted Michigan to determine whether fall-planted terminated glyphosate 1 wk prior (early ter...
