  2009 DEC 24 - (VerticalNews.com) -- According to recent research from Iran, "For evaluation of microelements distribution in alfalfa shoot in saline condition an experiment was conducted in hydroponic condition on four cultivars (Sistan, Golestan, FAO2566 and Hamedani) in five salinity levels as 0, 50, 100,150 and 200 mM NaCl in Hoagland media in a RCBD with three replicates. increasing salinity affected all elements except P. Increasing salinity decreased K+, Ca2+ and N concentration in leaf but increased Mg2+, Na+ and Cl-. ...read more

  2009 DEC 24 - (VerticalNews.com) -- "This research was conducted to determine the effects five different nitrogen doses (N 0, 50, 100, 150 and 200 kg ha(-1)) and four phosphorus doses (P2O5 0, 40, 80 and 120 kg ha(-1)) on root and leaf yields and yield components of forage turnip (Brassica rapa L.) under Mediterranean region of Turkey in the 2006 and 2007 growing seasons," investigators in Isparta, Turkey report.

  "According to averages of two years, the effect of N doses was significant at all components and P doses were significant at leaf yield, leaf DM yield, root and leaf CP contents, leaf CP yields, ADF and NDF contents in root and leaf. N doses increased root length, root diameter, root yield and DM yield, leaf yield and DM yield, root CP content and yield, leaf CP content and yield, P treatments increased leaf yield, leaf DM yield, root CP content, leaf CP yields," wrote M. Turk and colleagues, Suleyman Demirel University ...read more

  2009 DEC 24 - (VerticalNews.com) -- According to recent research from Iran, "To study the effect of biofertilizer on soybean seed vigor under water deficit stress, two experiments were conducted under field and laboratory conditions. Field study was done as split factorial RCBD and laboratory experiment was conducted as a factorial CRD with 4 replications."

  "The seeds were evaluated by cold test. Experimental factors were biofertilizer (seed inoculation with Bradyrhizobium japonicum, Bradyrhizobium japonicum + Pseudomonas fluorescens and Bradyrhizobium japonicum + Glomus mosseae), cultivar (Zalta Zalha and line ClarkxHobbit) and water deficit stress (irrigation after 50 [normal irrigation], 100 [mild stress] and 150 [intense stress] mm evaporation from pan Class A in parents field). Water deficit stress had negative effect on seed quality. Under field condition, the co-inoculation of the seeds with B. japonicum and P. fluorescens improved final field emergence and field emergence index under water deficit stress. Under lab condition, biofertilizer application was effective on all attributes. In the condition of normal irrigation, the inoculation of 'Zalta Zalha' seeds with B. japonicum and B. japonicum and seeds of ClarkxHobbit line with G. mosseae increased final germination percent and seedling vigor index. In mild stress, B. japonicum and G. mosseae inoculation of 'Zalta Zalha' and B. japonicum inoculation of ClarkxHobbit line increased primary stem length and seedling vigor index. In the condition of intense stress, the inoculation of Zalta Zalha cultivar with B. japonicum and G. mosseae and ClarkxHobbit line with B. japonicum and P. fluorescens increased primary stem length," wrote I.
