Defoliation produced by abiotic factors and the subsequent re-growth can reduce sugar beet (Beta vulgaris L.) sucrose content and final sugar yield. Field experiments were conducted during 2003 and 2004 growing seasons in the farm of Hellenic Sugar Industry SA, Larissa factory, central Greece. Three sugar beet cultivars (Rival, Europa and Corsica) were ordinary irrigated till the beginning of J...

the effects of above and below-ground competition between chenopodium album and sugar beet (beta vulgaris) on growth, yield and quality of two sugar beet cultivars of morphologically contrasting growth habit have been investigated a factorial experiment (2 × 4) under glass-house conditions in a randomised complete block design with three replications was done. c. album and two sugar beet cultiv...

the main objective of this research was the measurement of soil characteristics, land evaluation and determination of potential yield of sugar beet in yekanat plain of marand. for doing this, firstly, yield potential of sugar beet was estimated by fao method and secondly land evaluation of different soil units for sugar beet cultivation was determined by parametric method. results showed that m...

to determine the effects of different irrigation and salinity levels on qualitative and quantitative yield of sugar beet, an experiment was conducted for two years (2006-07)at torogh agricultural research center, mashhad, iran, using two sprinkler systems. each of the two irrigation systems was connected to two water sources with 1 and 6 ds/m salinity. irrigation was performed via two sprinkler...

A field experiment was carried out at the Research Center of Barkat-e-Jovein, Jovein agro-industries, Northeastern Iran, during 2008 to evaluate the effect of concentration and time of boron foliar application on root yield and quality of sugar beet (Beta vulgaris). Treatments consisted of 3 application times (30, 45 and 60 DAP) and 4 application rates (spraying with concentrations of 0, 4, 8 a...

most part of durum wheat is produced in semitropical dryland regions in iran. heat and drought stresses are the main constraints in these regions. so, identification of durum wheat cultivars with high yield and tolerant to these stresses is the main breeding strategy in dryland agricultural research institute. the genotype capeiti was evaluated at gachsaran agricultural research station from 19...

The effects of soil water deficit and interspecific plant interaction were studied on the dry matter (DM ) yield of white clover and ryegrass and on the morphogenesis of white clover. Plants were grown either: (1) individually (no interaction); or in a mixture of equal plant numbers with either (2) just shoot interaction, or (3) both shoot+root interaction. Plants were subjected to soil water d...

the aim of this study was to investigate the effect of tillage methods to obtain suitable seedbed for monogerm seed. therefore, a split plot experiment based on a randomized complete block design (rcbd) with three replicatians was conducted at darab station of fars province. the main plot was seedbed prepration at two levels including fall and spring season. subplot included 1) moldboard plow a...
