water and soil salinity in some regions of isfahan, east azerbaijan, and west azerbaijan provinces and also other parts of the iran are the main hindrance for crop planting. seeds of the tolerant crops to salinity such as cotton and sugar beet may have optimal germination and give acceptable performance if they become far from salt accumulation areas. to evaluate the effects of different planti...

Re®nements of high residue cropping practices are needed to provide crop producers viable systems that are both economically and environmentally sound. Several tillage treatments in combination with row-placed fertilizer were evaluated in a 3 year study on maize (Zea mays L.) on a Luvic Phaeozem in southern Wisconsin, USA. Tillage treatments included fall chisel, fall and spring in-row residue ...

manual planting of sugar-beet stecklings is a very laborious and time-consuming opera-tion. to overcome the problems, and decrease the cost of operation to a reasonable level, a semi-automatic steckling transplanter was designed. the suitability of the steckling trans-planter with regard to the agrotechnical requirements of sugar-beet stecklings was stud-ied and the main field performance param...

This research was conducted in 2007 and 2008 cropping seasons in the experimental field of Shahid Salemi, Ahvaz, south west of Iran. In each year, the study consisted of a split split-plot experiment, using Randomized Complete Block Design (RCBD) with three replications. Four irrigation levels including irrigationoff at the 8 leaf, the 12 leaf and the tasseling stages and optimum irrigation wer...

in order to evaluate the delay cropping on yield and yield component of two canola cultivars and selecting the best genotype and row spacing, an experiment was conducted at three years (2007, 2008 and 2009) in gorgan research station. this experiment was arranged in spilt-factorial based on randomized complete block design with four sowing dates (28 oct., 12 and 28 nov. and 12 dec.) as main plo...

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...

Recent developments in cotton (Gossypium hirsutum L.) production technology in the Delta include drill planting cotton in an ultra-narrow-row (UNR) production system. Ultra-narrow-row cotton is a low-input production system designed to maximize economic returns. The premise is that UNR cotton will be lower yielding, but the reduction in input costs will result in a larger profit margin. Researc...
