Potassium solubilization by bacterial strain in waste mica

Abstract: The release of K from waste mica (muscovite and biotite) was tested with 4 K-solubilizing isolates collected from maize rhizosphere, for 7, 14 and 21 days of incubation at 28 ± 2°C. K-solubilization by different bacterial isolates showed significant change on muscovite and biotite powder supplemented plates and the amount of K released varied from 1.28 - 46.75 μg/ml. The soluble K contents in all isolated treatments were significantly higher than control. Herein, isolate KSB 2 had higher K-solubilization ability when compared with other isolates (KSB 1 , KSB 3 and KSB 4 ) in vitro DOI: http://dx.doi.org/10.3329/bjb.v43i2.21680 Bangladesh J.

Alleviation of adverse effects of drought stress on common bean ( Phaseolus vulgaris L.) by exogenous application of hydrogen peroxide

Abstract: Effects of seed pretreatment by hydrogen peroxide (H 2 O 2 ) on drought tolerance in common bean plants ( Phaseolus vulgaris L.) were studied. Drought stress caused highly significant decrease in growth parameters, photosynthetic pigments, total carbohydrates and phytohormones. An increase drought stress caused highly significant increase in compatible solutes and polyamine contents as antioxidants and ABA contents in shoots of common bean plants. H 2 O 2 -pretreatment of seeds enhanced all the above parameters than the waterpretreated seeds (control) under drought condition. Results suggested that H 2 O 2 , a stress signal could trigger the activation of antioxidants in seeds which persists in the plants to alleviate the oxidative damage leading to improvements in physiological attributes for the plants growth under drought.

Prevalence of pathogenic bacteria in common salad vegetables of Dhaka Metropolis

Abstract: Microbial quality of common salad vegetables (viz. carrot, cucumber, tomato and lettuce) collected from Dhaka metropolis was analysed to detect the presence of bacterial pathogens. The occurrence of huge numbers of fecal coliforms (1.0×10 4 - 4.09×10 6 cfu/g), Escherichia coli (1.0×10 4 - 5.0×10 8 cfu/g), Staphylococcus aureus (2.0×10 5 - 5.95×10 7 cfu/g), and Listeria spp. (1.5×10 6 - 6.5×10 7 cfu/g) were detected in all the tested samples. Interestingly, occurrence of viable but non-culturable (VBNC) bacteria was also noticed.

Residual impact of wellgrow formulation and npk on growth and yield of wheat (triticum aestivum l.)

Abstract: Effect of concentrate organic manure (wellgrow grain and wellgrow soil) and NPK improved the growth and yield of wheat Significant improvement in terms of growth parameters like plant height, tillers, dry matter production and productive tillers with application of 120 : 60 : 60 NPK + 300 kg wellgrow soil/ha and at par with application of 120 : 60 : 60 NPK + 300 kg wellgrow grain/ha, treatment receiving 100% NPK + 300 kg wellgrow soil/ha resulted maximum grain yield (4545 kg /ha) Treatment of 100% NPK + 300 kg wellgrow grain/ha maintained higher straw yield (5715 kg/ha) and test weight (4410 g) due to application of 100 % NPK along with 200 kg wellgrow soil/ha whereas it was at par with application of 75 and 100% NPK with both levels of wellgrow formulation DOI: http://dxdoiorg/103329/bjbv44i122738 Bangladesh J Bot 44 (1): 143-146, 2015 (March)
