for determination of water stress effects in different growth stages of sugar beet and optimum water usage on quantity and quality of sugar beet, this study was performed using randomized complete blocks design in factorial experiment with 12 treatments and 4 replications from 1999 to 2001 in agricultural research center of hamadan. the first factor was non-irrigation in 3 stages of growth (s1-...

eight pollinators (as pollen parents) and four cms lines (as seed parents) differing in salinity and drought tolerance were evaluated using agro-morphological traits and microsatellite markers. root yield, leaf weight, sugar content, sodium content (na+), potassium content (k+), a-amino nitrogen content, alkalinity coefficient, molasses sugar, white sugar content, extraction coefficient of suga...

sustainable agriculture for producing food is not possible without optimal use of water resources. because of the limitation of water resources, deficit irrigation would be essential to increase water productivity. in order to evaluate the effects of deficit irrigation on quality and quantity of sugar beet, an experiment was carried out in a farm in miandoab agricultural research station for 2 ...

The root is an important plant part contributing to peanut productivity underwater-limited conditions. Root volume, root surface area and root diameter may becharacters responding to pre-flowering drought (PFD) in peanut. The objectives ofthis study were to investigate the responses to PFD for root surface area, rootvolume and root diameter and to determine the inter-relationships among theresp...

In a 3-year experiment (2002-2004), five N rates (0, 60, 120, 180, 240 kg N ha-1) were applied to sugar beets arranged in a Randomized Complete Block design with six replications. Experimentation took place under the semi-arid, irrigated conditions of central Greece. The aim of this work was to study the late season response of sugar beet crop to N fertilization as assessed by non-destructive m...

Water shortage and low phosphorus (P) availability limit yields in soybean. Roots play important roles in water-limited and P-deficient environment, but the underlying mechanisms are largely unknown. In this study we determined the responses of four soybean [Glycine max (L.) Merr.] genotypes [Huandsedadou (HD), Bailudou (BLD), Jindou 21 (J21), and Zhonghuang 30 (ZH)] to three P levels [applied ...

objective: a field experiment was conducted at dorud region, iran, during 2013. the aim of this research  was study on effect of different biofertilizers and irrigation closed time on some agronomic characteristics of sugar beet (beta vulgaris l.). methods: the experimental design was factorial based on rcbd with three replications. treatments were three irrigation closed time [oct-6 (a1), oct-...
