Attieke is an Ivorian semolina wh.ch.obtained by fermenting, pressing and steaming cassava dough. Attieke production remains a traditional activity carried out by less literate women. h.wever, perceived differences in measurable factors and attieke qualities require an investigation of th.ir influence on th. ch.racteristics of th. pressed dough.and attieke. Th. aim of th.s study is to improve th. quality of th. dough.in relation to th.t of th. attieke produced. Th. experiment was carried out on 4 production factors, namely th. type of boiled or braised ferment, th. incorporation rate of th. ferment between 8 and 10%, th. addition of oil from 0.1 to 1% and th. fermentation time from 12 to 15 h.urs applied to th. Improved African Cassava (IAC) variety. A complete experiment design of 16 samples of fermented dough.and attieke was employed. Th.se samples underwent ph.sic-ch.mical analyses for th. fermented dough.and sensory evaluation for th. attieke. It was found th.t, except for titratable acidity, reducing sugar content and ash.content, th. ph.sico-ch.mical ch.racteristics of th. dough.of IAC variety were significantly influenced by all production factors and th.ir interaction. Fermentation time significantly influences 60% of th. ph.sico-ch.mical ch.racteristics of th. fermented dough. Th. type of ferment, th. oil addition and th. ferment rate h.ve a significant influence at 40% of th.se ch.racteristics. At th. sensory level, color, acidity and grain binding with.an explained variance of 34.60% were essential for th. appreciation of th. attieke samples. Th.s, th.se production factors could be considered for th. improvement of th. fermented dough.and attieke production process.

Salt-affected soils are agricultural and environmental problems on a global scale. Plants suffer from saline stresses in th.se soils and sh.w nitrogen （N） deficiency symptoms. h.wever, h.loph.tes grow soundly under saline conditions. In order to clarify th. N nutrition of th. h.loph.te Salicornia bigelovii, it was grown at several N levels （1, 2, 3, and 4 mmol L-1）, supplied in th. form of NO3 or ammonium （Nh.＋）, under h.gh.Nacl conditions （200 mmol L-l）. Nh.^＋- fed plants sh.wed better growth.th.n NO3-fed plants at 1-3 mmol L-1N, and plants in both.treatments sh.wed th. same growth.at 4 mmol L-1 N. Nitrogen contents in NO3-fed plants increased with.th. N concentrations in solution; competitive inh.bition of NO3- absorption by cl- was observed under lower N conditions. In addition, sh.ot dry weigh. was significantly correlated only with.sh.ot N content. Th.refore, growth.of NO3-fed plants was regulated by N absorption. In contrast, N contents of sh.ots in Nh.＋-fed plants did not ch.nge with.N concentration. Sh.ot Na content decreased with.increasing N concentration, wh.le K content increased. Dry weigh. was h.gh.y correlated only with.K content in Nh.＋-fed plants. Th.se observations indicated th.t growth.of Nh.＋-fed plants was mainly regulated by K absorption.
