a field study was conducted at the college of agriculture, shiraz university, shiraz, iran to evaluate the effect of different crop residue and nitrogen rates on yield and yield components of two dryland wheat (triticum aestivum l.) cultivars. the experiment was conducted as a strip split plot with four replications. vertical plots included two dryland current wheat cultivars (azar2 and nicknej...

to assess the interaction effects of weeds, sowing rate, and n splitting on dryland wheat yield, field experiments were conducted in two years (2007 and 2009) at the college of agriculture in shiraz university. the treatments were replicated four times and analyzed as a split- split plot in a randomized complete block. the weedy and weed free were treated as the main plots, the wheat sowing rat...

In a two-part experiment, the first parcel is certified organic vineyard and, consisting of Cabernet Sauvignon cv. vines grafted onto 1103P rootstock. The second conventional vineyard, with 5BB Using Split-Plot Design based on stress levels, experiment set up three repetitions, two main plots representing Organic and Conventional each split into sub-plots. Predawn leaf water potential values we...

We calculate the electronic spectrum of bilayer graphene in perpendicular magnetic fields nonperturbatively. To accomodate arbitrary displacements between the two layers, we apply a periodic gauge based on singular flux vortices of phase 2π. The resulting Hofstadter-like butterfly plots show a reduced symmetry, depending on the relative position of the two layers against each other. The split o...

to evaluate the effects of fertilizing and deficit irrigation regimes on some chemical properties of soil and plant, an experiment was conducted during 2007 and 2008 growing seasons. experimental design was a split plot based on a randomized complete block design with four replications. the treatments consisted of three deficit irrigation regimes (main plots) and six soil fertilizing systems (s...

In order to study the effect of irrigation interval, N fertilization and plant density on yield and yield components of fenugreek, a split-split-plot experiment was conducted in Darmian, Iran in spring 2010. The experiment was conducted in randomized complete block design with three replications. The main plots were subjected to different irrigation intervals of 5 and 10 days. The sub-plots wer...

The objective of this research was to investigate the effect storage conditions different onion set sizes on plant growth, yield and quality bulb crop. Treatments comprised two cultivars (Kamlin Saggai), (refrigeration at 2-4 ○c room temperature around 32○c) three (large-bulb diameter 2.2-2.7 cm, medium 1.6-2.1cm small 1-1.5 cm). Experimental design split-split plot with replications. Cultivars...

The high quality and quantity seed production in old saxual shrubs are essential for regeneration and sustainable development of saxual forests in desert areas. The objective of this study was to determine the effects of different pruning height on saxual seed production. The study was carried out in an obviously wilted saxual forest located in Ashkezar desert in Yazd in 1994. The experiment wa...
