to evaluate yield and productivity indices of maize and sugar beet intercropping with different planting ratios, a field experiment was conducted in randomized complete block design with three replication at hamedan province in nahavand, in 2013. the planting ratios were 100:0, 75:25, 50:50, 25:75 and 0:100 (maiz: sugar beet) using replacement method. results showed that intercropping had signi...

Climate is one of the most important factors that influence the quality and quantity of crops. Understanding the natural features of any region, especially about the climate, can play a major role in making plans and land use planning. Sugar beet, is one of the major industrial plants, that in addition to producing one of the most fundamental basic needs of society, namely sugar, it can have ot...

QTL mapping in autopolyploids is complicated by the possibility of segregation for three or more alleles at a locus and by a lack of preferential pairing, however the subset of polymorphic alleles that show simplex segregation ratios can be used to locate QTLs. In autopolyploid Saccharum, 36 significant associations between variation in sugar content and unlinked loci detected by 31 different p...

This issue of Interface Focus is being used to introduce readers of Interface to research into the use of plants to supply mankind with renewable energy and material resources. This field is given the general name of biorenewables research, but over the past few years it has come to public attention through media coverage surrounding one type of biorenewable product, liquid biofuels. Biofuels r...

Glyphosate is the active ingredient in the pervasive herbicide, Roundup. Its usage on crops to control weeds in the United States and elsewhere has increased dramatically in the past two decades, driven by the increase over the same time period in the use of genetically modified (GM)1 crops, the widespread emergence of glyphosate-resistant weeds among the GM crops (necessitating ever-higher dos...

Recent advances in Agricultural Engineering include image processing, robotics and geographic information systems (GIS). Some tasks are still accomplished manually, like drawing plantation lines that optimize productivity. Herewith we present an algorithm to find the optimal plantation lines in linear time. The algorithm is based upon classical results of Geometry which enabled a source code wi...

today climate change is one of the most important human concerns this fact affected human life in different ways .  one of the most important impacts of climate change is on crops yield so that change in temperature  regime  particularly maximum and minimum  temperatures  is noticeably change plants production . in this research , is considered to  impact of climate change on water requirement ...

Crop sequence patterns are considered as those schemes farmers apply within a single field to succeed crops over time, regardless of whether the same crop is grown continuously or a diverse rotation is used. This study aimed at identifying these patterns for a large and representative area in Northern Germany during a six-year period from 2005 to 2010. The analysis was carried out for the entir...

A systematic approach to ensuring the stability of field and grassland feed production is justified. comparative assessment individual types forage crops given select most effective sour- ces in absence a shortage chemicals agricultural. The main directions for public livestock feed, improving quality components crops, especially terms protein sugar content, are shown. An economic efficiency wa...

ethanol is a clean and renewable energy source. the necessity of ethanol usage, instead of fossil fuels or mixed with them, in order to reduce environmental pollution resulted in increase of ethanol production from 50 million m-3  in 2007 to 85 million  m-3 in 2012. the present study aimed to compare the cost of bio-ethanol production from sugar beet with other agricultural crops, and also econ...
