A suitable planting pattern and irrigation strategy are essential for optimizing winter wheat yield and water use efficiency (WUE). The study aimed to evaluate the impact of planting pattern and irrigation frequency on grain yield and WUE of winter wheat. During the 2013-2014 and 2014-2015 winter wheat growing seasons in the North China Plain, the effects of planting patterns and irrigation fre...

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 the tropics, cowpea is often intercropped with maize. Little is known about the effect of the intercropped maize on N2-fixation by cowpea or how intercropping affects nitrogen fertilizer use efficiency or soil N-uptake of both crops. Cowpea and maize were grown as a monocrop at row spacings of 40, 50, 60, 80, and 120 cm and intercropped at row spacing of 40, 50, and 60 cm. Plots were fertili...

A field inoculation method was developed to produce Meloidogyne spp. infestation sites with minimal quantities of nematode inoculum and with a reduced labor requirement compared to previous techniques. In a preseason-methyl bromidefumigated site, nematode egg suspensions were delivered at concentrations of 0 or 10(x) eggs/m of row where x = 2.12, 2.82, 3.52, or 4.22 through a drip line attached...

Increasing level of carbon dioxide CO2 due to industrial activity is primarily cause of global warming. Planting Artoplex lentiformis can help to reduce atmospheric CO2 buildup partly replacing use of fuels and by carbon storage. The objective of this study was to determine the effects of row spacing on carbon storage. A split- plot design with three replications included three row spacing (2×2...

to study the effect of planting pattern and water quantity on potato yields under drip irrigation, this research was conducted using a split plot based on a randomized complete block design with four replications in three regions (mashhad, ardebil and damavand, iran) during 2003-2004. nine treatments were used. the main-plots were three levels of irrigation: 100%(i1), 80%(i2), and 60%(i3) of cr...

Pinus taeda L. plantations in the United States are typically established using rows that are spaced 3 to 4 m apart. Although one company now plants pines in 6.1 m rows, reports on performance using this row spacing are rare. This paper provides a case study (established at the Solon Dixon Forestry Education Center) that compares two densities [672 vs 1344 seedlings per ha (SPH)] when fixing th...

The data of long-term research on increasing the yield and quality coriander seeds by selecting most productive varieties improving basic techniques its cultivation technology are presented. It has been established that is Akkord cultivar, which we have bred released. Biochemical, biological agrotechnical features studied. High laboratory germination was revealed (90.1%), field varied from 88.5...

Bed planted wheat systems offer a new alternative for the traditional wheat producer to provide opportunities for crop rotation, more efficient use of water, and new techniques of nutrient management. This study was conducted to determine if planting winter wheat (Triticum aestivum L.) in Oklahoma on raised beds can maintain grain yields while providing more options in the cropping system. Expe...
