Effectiveness of castor (Ricinus communis) and velvetbean (Mucuna deeringiana) amendments was tested for suppression of the root-knot nematode (Meloidogyne arenaria) and growth of okra (Hibiscus esculentus) in three greenhouse experiments. Regression analysis was used to relate nematode population data or plant growth responses to various rates (0, 1, 2, 4, or 8 g/560 cm(3) soil pot) of each am...

Phytoremediation of creosote-contaminated soil was monitored in the presence of Tall fescue, Kentucky blue grass, or Wild rye. For all three grass species, plant growth promoting rhizobacteria (PGPR) were evaluated for plant growth promotion and protection of plants from contaminant toxicity. A number of parameters were monitored including plant tissue water content, root growth, plant chloroph...

Plant-parasitic nematodes are one of the major pests, causing damage to almost all cultivated crops throughout the world. Present nematode control measures pose a threat to the environment; therefore, use of natural compounds is being emphasized to control these deterrents. 28-Homobrassinolide (HBl) is one such naturally synthesized compound that is ubiquitously distributed in plant kingdom. In...

'Dwarf stature' maize variety offers promises to withstand unfavorable growth environments of Kharif season. But, for developing such variety, dwarf stature inbred lines must be available. Here, twenty-four F3 populations of white maize were evaluated though assessment of their genetic variability, heritability, and character association for selection of dwarf stature promising lines based on y...

the life history of an acarid mite, tyrophagus putrescentiae (schrank), on fusarium graminearum clade was investigated at 25 â± 1â°c, 60 â± 5% rh and a photoperiod of 16: 8 (l: d) h. incubation period for egg hatch, larval and nymphal periods and adult longevity were 2.22 â± 0.06, 3.46 â± 0.12, 4.84 â± 0.16 and 10.05 â± 0.9 days, respectively. the average life span of males and females were 22....

the length-weight relationships for three fish species from beheshtabad river, karun river drainage (western chaharmahal and bakhtiari provinces, iran) were investigated. the values of the slope parameter ( b ) in the length-weight relationship equations were determined as 2.79 for capoeta damascina , 3.10 for chondrostoma regium and 3.09 for oncorhynchus mykiss , all of which were significantl...

black bengal goat is the heritage and one of the potential genetic resources of bangladesh. least-squares means for body weights at birth, 3, 6, 9 and 12 months of age were 1.09, 5.12, 8.02, 10.92 and 14.47 kg, respectively. sex of the kid has significant (p

Proving of rhizobia’s other abilities in spite of Nitrogen fixation ability and considering these bacteria as plant growth promoting rhizobacteria (PGPR), researching tasks in this field have increased. Now, it’s completely proved that we can find such strains among many more strains of each rhizobial group that can also do effective process in plant growth promoting as plant growth hormones pr...

two fungal species glomus mosseae and glomus intraradices as well as meloidogyne javanica nematode were used in order to evaluate the effects of arbuscular mycorrhizal fungi on control of different populations of root-knot nematode in tomato. a greenhouse test was established as factorial experiment based on completely randomized design with 8 treatments and 4 replicates followed by mycorrhizal...
