Salinity is a major detrimental factor for plant growth and crop productivity that could be alleviated by the use of promoting bacteria (PGPB) with protective role in such stressful conditions. In this study, four native strains genus Pseudomonas were isolated from both strongly saline soil rhizosphere soybean plants grown slightly soil. These isolates able to tolerate high NaCl concentration, ...
Bamboo plant is a potential source of growth promoting bacteria (PGPB). Phosphate solubilizing ability an important characteristic PGPB. This study aims to isolate phosphate around the bamboo clumps using natural media. The are trapped media consist 70 gram cooked rice and banana peel. were stored in plastic boxes with four types treatments: 1) tightly closed, 2) covered tissue, 3) leaves, 4) u...
In previous work, we showed that coinoculating Rhizobium leguminosarum bv. viciae 128C53 and Bacillus simplex 30N-5 onto Pisum sativum L. roots resulted in better nodulation and increased plant growth. We now expand this research to include another alpha-rhizobial species as well as a beta-rhizobium, Burkholderia tuberum STM678. We first determined whether the rhizobia were compatible with B. s...
Background Sorghum, a grassy non-halophyte, it is both drought and salinity tolerant, and is considered a promising crop for semiarid regions. During the last 20 years, its culture has expanded in Brazilian production by 780%, reaching 1,928,970 tons in 2009 [1]. Salinization of the soil and lack of rain are increasing constraints in semiarid regions. They predominate in northeastern Brazil. Th...
In this Crystal Ball we describe the negative effects of the scheme of intensive agriculture of the green revolution technology. To recover the contaminated soils derived from intensive farming is necessary introduce new successful technologies to replace the use of chemical fertilizer and toxic pesticides by organic fertilizers and biological control agents. Our principal speculation is that i...
Drought in heavy metal polluted arid and semiarid regions severely inhibits the plant growth phytoremediation potential by affecting photosynthesis, antioxidant defense mechanism, other biochemical processes. In present study, we explored role of growth-promoting bacteria (PGPB) on Zea mays efficiency Chromium (Cr) contaminated soils under drought stress assessing tolerance, photosynthetic gas ...
به منظور بررسی تأثیر کاربرد محلول پاشی باکتری های افزاینده رشد گیاه و آزمایشی در سال زراعی 1388 در مزرعه تحقیقاتی دانشکده کشاورزی دانشگاه تربیت مدرس در غرب تهران و در قالب طرح بلوک های کامل تصادفی در 3 تکرار اجرا شد. تیمارها شامل نیتروژن از منبع کود اوره در دو سطح ( تأمین 70 درصد نیتروژن مورد نیاز گیاه 147 کیلوگرم نیتروژن خالص و تأمین 100 درصد نیتروژن مورد نیاز گیاه 210 کیلوگرم نیتروژن خالص ) و...
Biofertilization with plant growth-promoting bacteria (PGPB) could optimize chemical fertilization for strawberry crop cultivation. A greenhouse study was arranged to assess the impact of an isolated PGPB consortium from halophytes on development, physiological traits, and nutritional balance subjected two phosphorus limitation treatments (with without insoluble form application). had a positiv...
