Los sistemas agroforestales (SAF’s) de café tienen un alto potencial en la captura carbono (C) gracias a gran diversidad especies leñosas usadas como sombra. El objetivo del presente estudio fue evaluar el biomasa vegetal aérea, mantillo y materia edáfica diferentes profundidades suelo cinco SAF’s región cafetalera Huatusco, Veracruz, México. estudiados fueron: pleno sol (03.PSC-MZ, 04.PSC-ZI),...
The interactions of Heterodera glycines at four egg inoculum levels (0, 100, 1,000, and 10,000 per pot) and three cyst levels (0, 100, and 200 per pot) and Calonectria crotalariae at 500, 5,000, and 50,000 microsclerotia per pot were evaluated on soybean. At the two lowest nematode egg levels, the presence of C. crotalariae did not affect nematode reproduction. At 10,000 eggs per pot, however, ...
Pot experiment was conducted to study the alternate and fixed partial root zone drying on irrigation water use efficiency phosphorus absorption of corn (Zea mays L.) in a gypsiferous soil during spring growing season. The included three techniques, which were conventional (C1), alternating root-zone (APRD) (FPRD), levels phosphate fertilizer application (40, 80, 120 Kg h-1), for stages plant gr...

Recurrent vulvovaginal candidiasis (RVVC) is seen in 5% of women with Candida vaginitis. Use of fluconazole as prophylactic treatment has been suggested for RVVC. The aim of the present study was to evaluate the efficacy of fluconazole suppressive therapy in RVVC patients, as a randomized, placebo-controlled, double-blind prophylactic study. Among the 330 women with acute symptomatic vulvovagin...
Nitrogen fertilizer management has a special priority for safflower economic production. Increasing the efficiency of this element, in addition to increasing economic benefits, also reduces environmental pollution. Therefore, a factorial experiment was conducted in the form of statistical design of complete randomized blocks with three replications at Safiabad Agricultural and Natural Resources...
Intercropping systems compared to monoculture systems can more efficiently use the existing resources which ultimately will lead to increased plant performance. Therefore, to evaluate the benefits of intercropping maize and beans and assess its impact on yield and yield’s component, an experiment was conducted in factorial design with randomized complete block design in three replication, in 20...
پتاسیم قابل استفاده در خاک معیار مهمی برای رشد گیاه و تولید عملکرد است. برخی باکتری های خاک می توانند پتاسیم قابل استفاده را برای رشد گیاهانافزایش دهند. به منظور جداسازی و بررسی میزان کارایی این باکتری ها در خاک، تعداد پنج نمونه خاک از نظر وجود باکتری های آزاد کننده پتاسیم مورد ارزیابی قرار گرفتند و در نهایت شش ایزوله به عنوان باکتری های موثر، جداسازی شدند. براساس بررسی های میکروسکوپی، آزمون ها...
abstract this study evaluates the iranian pre-university english textbook in terms of needs, objectives, content, and methodology. the study was designed on the qualitative- quantitative survey basis using interviews and questionnaires, a researcher-made textbook evaluation checklist and a needs analysis questionnaire. the textbook evaluation questionnaire was used in this study to elicit the ...
chapters 1 and 2 establish the basic theory of amenability of topological groups and amenability of banach algebras. also we prove that. if g is a topological group, then r (wluc (g)) (resp. r (luc (g))) if and only if there exists a mean m on wluc (g) (resp. luc (g)) such that for every wluc (g) (resp. every luc (g)) and every element d of a dense subset d od g, m (r)m (f) holds. chapter 3 inv...
