to study the effect of variable irrigation in spring on water use efficiency, quantity and quality of root and sugar yield of two sugar beet cultivars shirin and rasolan, an experiment was conducted at safiabad agriculctura research center during 2003-04 and 2004-05 cropping seasons. the experiment was designed in  a split plot with four replications in which five water supply treatments 25, 50...

in order to study the effect of intensity and exposure duration magnetic field on wheat (triticum aestivum l.) seed germination an experiment was conducted in laboratory of ferdowsi university of mashhad, iran. the experiment was including 11 treatments as three level of magnetic field intensities (pretreatment of seeds with 50, 100 and 150 mt magnetic field) and three exposure durations (10, 2...

Nematodes are tiny but complex unsegmented roundworms that are anatomically differentiated for feeding, digestion, locomotion, and reproduction. These small animals occur worldwide in all environments. Most species are beneficial to agriculture. They make important contributions to organic matter decomposition and to the food chain. Some species, however, are parasitic to plants or animals. Pla...

Sixty-nine herbaceous perennial ornamentals in 56 genera were evaluated for root galling after 2 months in soil infested with Meloidogyne hapla under greenhouse conditions. Plants were rated susceptible or resistant based on the number of galls present on the root system. Thirty-six percent had more than 100 galls on the roots (similar to 'Rutgers' tomato controls) and were rated susceptible. T...

in process of sucrose determination in sugar beet, pulp analysis by polarometric method is done on the basis of fresh root weight .the volume of the juice of 26 grams of the pulp is considered 23 ml that with 177 ml of clarifying agent would be 200 ml. drought stress and dehydrated root reduce. the volume of the pulp extract of 23 ml. the objective of this experiment was to determine the proper...

The effects of two water regimes (well-watered condition or drought stress) on root length,root surface area and root volume were tested on two peanut genotypes (the drought-resistantvariety HuaYu 22 (HY22) and the drought-sensitive variety HuaYu 23 (HY23)), measured 101days after sowing. The roots were sampled from the upper (0–40 cm) and deeper (40–100 cm)soil layers. Root diameter was measur...
