Two schools of thought exist regarding the planting of bare-root seedlings. One school favors the “pull-up” m e t h o d w h e r e t h e s e e d l i n g i s p u l l e d u p 3 t o 1 0 c m a f t e r p l a c i n g t h e r o o t s i n t h e p l a n t i n g h o l e .

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...
In order to investigate the effect of effect of date and depth of tuber cultivation on some agronomic traits of potato cultivars in autumn and spring cultivations, a split factorial experiment was carried out based on randomized complete blocks design with three replications in Ardabil Agricultural and Natural Resources Research Station during the two cropping year 2017-2018. Planting date as t...
Poor emergence resulting in inadequate stand establishment is a major problem associated with direct-seeded rice production, especially for semidwarf cultivars. In order to gain information on the problem, plant type related to gibberellic acid (GA3) and seeding depth was studied. A total of 21 cultivars including 9 semidwarfs and 12 talls had seed treated with GA3 at 25 parts per million (ppm)...
To investigate the effect of depth of planting holes on yield and yield components of three cultivars of watermelon in dry land conditions, a two-year study (2006-2007) was carried out in Varamin Agricultural Research Center, using a split plot randomized complete blocks design in three replications. Three cultivars of watermelon (Mahbube, Charleston Gray and Sugar Baby) were assigned to main p...
in order to study the phonological stages and growth period of invasive weed ranunculus ficaria based on degree days and to study the effect of planting depth on sprouting the tubers roots of this weed, two separate experiments were conducted in crd with 5 replications at ferdwosi university of mashhad in 2008. in the first study germinated tubers were planted in 5 cm depth and the observations...
Current planting depth recommendations for corn (Zea mays L.) producers range from 38 to 51 mm in the midwestern United States. Characterization of emergence and soil conditions at a depths under later-planted scenarios is important as days adequate field work April have been reducing may affect dates. Field studies were conducted Ohio 2017 2019 determine effects type on emergence, growth, grai...
