to study the effect of planting date, plant density and planting pattern on yield of corn (zea mays l) var. ksc 647 split plot factorial experiment in a randomized complete block design with four replications at bayranshahr lorestan province in crop year 2015 was conducted. factors examined included planting date in three levels: (25 may, 12 june and 29 june), density at three levels (60, 75 an...

The sensitivity of soybean [Glycine max (L.) Merr.] main stem node accrual to ambient temperature has been documented in greenhousegrown plants but not with fi eld-grown plants in the north-central United States. Biweekly V-node and R-stage, stem node number, internode length, and other traits were quantifi ed in an irrigated split-plot, four-replicate, randomized complete block experiment cond...

Increasing pumping costs and declining well capacities in regions like the Southern High Plains of Texas are requiring producers to adapt cropping practices for usewith irrigation levels that vary between complete replacement of crop evapotranspiration (ET) to none (i.e., dryland production). Grain sorghum [Sorghum bicolor (L.) Moench] is a crop suited to both dryland and various deficit irriga...

to evaluate the effects of planting date and plant density on morphological characteristics, including essential oil content of ajowan (trachyspermum ammi) a study was conducted during the years 2003 and 2004 at the experimental farm, faculty of agriculture, ferdowsi university of mashhad. treatments were laid out in a factorial form based on a complete randomized block design of three replicat...

introduction saffron as a winter active plant with low water requirement is the most strategic medicinal plant in arid and semi-arid parts of iran. this slow-growing plant has narrow leaves and no aerial stem, hence weeds can be overcome it. moreover, because of its root and canopy structure an important part of different resources is not used by this low input crop. therefore, the use of assoc...

The effect of seeding depth on emergence of red rice (Oryza sativa) ecotypes from Arkansas (AR), Louisiana (LA), and Mississippi (MS) was determined under dry-seeded rice production in clay and silt loam soils in Arkansas. By 21 d after planting (DAP), all red rice ecotypes had emerged from planting depths of 1.3, 2.5, 5.0, and 7.5 cm in both clay and silt loam soils. In silt loam soil, seedlin...

in order to evaluate the effects of planting date and corm density on yield and some other traits of saffron under climatic conditions of malayer in the west of iran, an experiment was conducted using split plots based on randomized complete blocks design with four replications. different planting dates (15th july, 15th august and 15th september) were allocated in the main plots and different c...
