water is the most important factor for agriculture development in iran. accordingly the optimal consumptione of water is very important. using pressurized irrigation system is one of the methods to improve agricultural water management. the objecttives of this research were to compare two irrigation methods of furrow and trickle irrigation systems impacts on quantity and quality characters of s...

The aim of this study was to investigate the effect  of irrigation period on the quality and quantity of yield and some morphological and physiological traits of three multigerm sugar beet genotypes named BP Mashhad, BP Karaj and 191. The experiment was in a split  plot  based on randomized complete block  design , carried out  at Motahari Research station of Sugar beet Seed Research Institute ...

An investigation was undertaken to study the feasibility of sugarbeet cultivation under Bangladesh condition during winter season of 2009-2010. Seeds of 14 sugarbeet genotypes were sown in the experimental field of Horticulture Research Centre of BARI, Gazipur on 10 November 2009. Visible root swelling in all genotypes started between 36 and 40 days after sowing (DAS). Nine genotypes had white ...

abstract one of the ways to increase economic and environmental efficiency of drainage systems is water table management. water table management consists of, controlled drainage and subirrigation. this study examines the effect of controlled drainage on yield, root distribution pattern and water use efficiency of maize (sc 704) in karaj. the experiment was performed as a randomized complete des...

to determine sugar content and root yield variation of new sugar beet hybrids under different irrigation levels, an experiment was carried out at zarghan agricultural research station offars agricultural and natural resources research center, shiraz, iran. the study was conducted as split block based on a randomized complete block design with three replications for two years, 2009-10, using lin...

in order to evaluate the effect of some qualitative traits of sugar beet (beta vulgaris l.) under irrigation water quality and different types of fertilizers, a field experiment arranged as split plot in rcbd design with three replications at research station of shahrekord university in 2013. the main factor include irrigation with urban wastewater at 2-4 leaf stage, 8-12 leaf stage and irrigat...

Improved root architecture is an effective strategy to increase crop yield. We demonstrate that overexpression of transcription factor gene MORE ROOT (TaMOR) from wheat (Triticum aestivum L.) results in more roots and higher grain yield in rice (Oryza sativa). TaMOR, encoding a plant-specific transcription factor belonging to the ASYMMETRIC LEAVES2/LATERAL ORGAN BOUNDARIES (AS2/LOB) protein fam...

for determination of irrigated sugar beet crop evaporation (etc) and water consumption a field experiment was conducted for three years (1991 to 1993)  in kabotar-abad agricultural experiment station. the climate was semi-arid according to gossen method with mean annual precipitation of 90 to 110 mm. the soil was esfahan series with a silty clay loam texture. the crop evapotranspiration was mea...

in order to investigate the relationships of some morphological traits at the early stages of three sugar beet cultivars with final yield at varying levels of water regines, a field experiment was carried out in karaj, and mashhad, in 2001-2003.  the objective of this study was to find the relation of some morphological traits of three sugar beet genotypes (7219-p.69, bp-karaj and 7112)  during...

The blind pursuit of high yields via increased fertilizer inputs increases the environmental costs. Relay intercropping has advantages for yield, but a strategy for N management is urgently required to decrease N inputs without yield loss in maize-soybean relay intercropping systems (IMS). Experiments were conducted with three levels of N and three planting patterns, and dry matter accumulation...
