the effect of 10-year continuous saffron cultivation on physical and chemical properties of a silty clay loam soil was investigated in a research farm of college of agriculture, shiraz university, shiraz (52 º 33ʹ e longitude and 29º 36ʹ n latitude), iran. this farm was irrigated with different regimes (100% of saffron's potential evapotranspiration (etp), 75%etp, 50%etp) including rain fed tre...

A concept design of a carrot seeder, filed for patent application, was successfully developed in this study. Farmers were visited and interviewed the data regarding their existing practices planting carrots, corresponding tools equipment requirements such as hill spacing, row spacing plant bed size gathered. These used input preparation simulation seeder with aid Solidworks software.
 The ...

We assessed the potential profitability of twin-row (TR) planting geometry as a water productivity-enhancing practice and skip-row irrigation (SRI) water-conserving in furrow-irrigated cotton (Gossypium hirsutum L.) soybean (Glycine max L.). Data from agronomic experiments carried on Dundee silt loam soils indicate that, average, TR increases by US$344 ha?1 for all-row irrigated (ARI), $401 SRI...

The nutritional status, juice quality and sugar production of sugarcane varieties RB867515 RB92579 were evaluated in the cane-plant cycle, as a function magnesium doses applied at bottom planting furrow. study, installed soil with Mg content equal to 0.61 cmolc dm-3, was conducted an experimental design randomized blocks four replications. study 2 x 5 factorial: two varieties: RB92579, five mag...

Furrow irrigation systems have a greater application capacity, are less costly, and use less energy than sprinkler systems but furrow irrigation produces greater runoff, erosion, and deep percolation losses. Phosphorus (P) and nitrogen (N) losses are associated with runoff sediment, and can be minimized by eliminating irrigationinduced erosion. Excessive leaching of inorganic and organic solute...

The mitotic spindle determines the cleavage furrow site during metazoan cell division, but whether other mechanisms exist remains unknown. Here we identify a spindle-independent mechanism for cleavage furrow positioning in Drosophila neuroblasts. We show that early and late furrow proteins (Pavarotti, Anillin, and Myosin) are localized to the neuroblast basal cortex at anaphase onset by a Pins ...

The article provides a biomechanical analysis of ventral furrow formation in the Drosophila melanogaster embryo. Ventral furrow formation is the first large-scale morphogenetic movement in the fly embryo. It involves deformation of a uniform cellular monolayer formed following cellularisation, and has therefore long been used as a simple system in which to explore the role of mechanics in force...

c-Myc (Myc) oncoprotein induction of genomic instability (GI) contributes to its initial transforming function and subsequent tumor cell evolution. We describe here a pathway by which Myc, via its target protein glycoprotein Ibalpha (GpIb alpha), mediates GI. Proteomic profiling revealed that the serine/threonine kinase Aurora B is down-regulated by GpIb alpha in p53-deficient primary human fib...

New irrigation methods under different nutritional element supplies for maize production was designed and tested for evaluate quantitative and qualitative parameters by split-plot arrangement according complete randomized block design with three replications. Different Irrigation regimes was belonged to main plots (Conventional furrow irrigation: CFI or A1, Alternate furrow irrigation: AFI or A...
