Zinc (Zn) is one of the essential micronutrients required for optimum plant growth. Substantial quantity of applied inorganic zinc in soil is converted into unavailable form. Zinc solubilising bacteria are potential alternates for zinc supplement. Among 10 strains screened for Zn solubilisation, P29, P33, and B40 produced 22.0 mm clear haloes on solid medium amended with ZnCO3. Similarly, P17 and B40 showed 31.0 mm zone in ZnO incorporated medium. P29 and B40 showed significant release of Zn in broth amended with ZnCO3(17 and 16.8 ppm) and ZnO (18 and 17 ppm), respectively. The pH of the broth was almost acidic in all the cases ranging from 3.9 to 6.1 in ZnCO3and from 4.1 to 6.4 in ZnO added medium. Short term pot culture experiment with maize revealed that seed bacterization with P29 @ 10 g·kg−1significantly enhanced total dry mass (12.96 g) and uptake of N (2.268%), K (2.0%), Mn (60 ppm), and Zn (278.8 ppm).

A pot culture experiment was conducted at the Bangabandhu Sheikh Mujibur Rahman Agricultural University (BSMRAU), Gazipur during kharif II, 2012 to evaluate the nodulation, biological nitrogen fixation and yield potential of genotypes of mungbean under varying levels of N application. There were 10 mungbean genotypes viz. IPSA 12, GK 27, IPSA 3, IPSA 5, ACC12890055, GK 63, ACC12890053, BU mug 4, BARI Mung 6 and Binamoog 5, each genotype treated with six levels of N (0, 20, 40, 60, 80 and 100 kg N ha-1) . Among the genotypes, the IPSA 12 at 40 kg N ha-1 produced the maximum number of nodules (14.54 plant-1) as well as the highest nitrogen fixation (2.684 mmol C2H4). This resulted in the highest seed yield (14.22 g plant-1). The genotype ACC12890053 recorded the lowest nodulation (6 plant-1), nitrogen fixation (1.134) and seed yield (7.33 g plant-1).Bangladesh J.

The interaction between the mycorrhizal fungus Glomus fasciculatum and the root pathogen Sclerotium rolfsii was studied in a pot culture experiment. The mycorrhizal fungus reduced the number of sclerotia produced by the pathogen and the pathogen reduced the percentage root infection and chlamydospore production by the mycorrhizal fungus. Root and shoot dry weights of the host and their P content was highest in plants inoculated with mycorrhiza only and lowest in plants inoculated with the pathogen only. Simultaneous addition of mycorrhizal inoculum and the pathogen reduced the severity of disease.

The degradation capacity of the four chlorimuron-ethyl-degrading strains, D310-1, LCY-2, LCY-3 and LCY-4, which identified asRhodococcussp.,Stenotrophomonas maltophilia sp,Bacillus subtilis sp., andRhodotorula mucilaginosasp., respectively, combined in different ways was examined in this study. Then the optimal degradation conditions and mitigation phytotoxicity of chlorimuron-ethyl on sensitive crop were investigated by both orthogonal test and pot culture experiment. The experimental results showed that the combination of four strains was adopted, and the removal rate of chlorimuron-ethyl reached the maximum of 90% in 30 days. Then the optimal degradation conditions were inoculum size 2.5%, temperature 28°C, pH 7.0 and the soil moisture 35%, and the mixed strains could eradicate 92.57% of chlorimuron-ethyl within 30 days. Furthermore pot culture experiment indicated that inoculation of mixed strains could also mitigate the phytotoxic effects of chlorimuron-ethyl on the growth of cucumber seedling.

A pot culture experiment on vermicomposting of cassava and sweet potato wastes/byproducts was conducted for March–May (season I) and June–August (season II) during 2010 at the Regional Centre of Central Tuber Crops Research Institute, Bhubaneswar, Orissa. The study revealed that the vermicompost prepared from biomass and byproducts of tuber crops had fairly higher levels of nitrogen (1.12–2.23%), phosphorus (0.26–0.88%), and potassium (0.33–1.29%) compared to initial status. The vermicompost prepared from sweet potato dry leaves had the highest nitrogen (2.23% and 2.03%), phosphorus (0.88% and 0.69%), and potassium (1.29% and 0.84%) content during both the years of study. Cassava thippi (tuber residue) required 40–43 days for the complete conversion into vermicompost, whereas all other biomass and byproducts needed more time (43–65 days). The rate of increase of earthworm weight and population was higher in vermicompost made from cassava and sweet potato thippi. Microbial counts indicated that populations of bacteria and fungi were higher in season I, whereas actinomycetes were higher in season II. The study indicated that all the biomass and byproducts of tuber crops can be effectively converted into high-value vermicompost.

Pot culture experiment and Petri dish bioassay were conducted to assess the allelopathic potential of Cyanthillium cinereum and Lantana camara on seed germination and seedling growth of Vigna unguiculata and Abelmoschus esculentus. Aqueous leaf and stem extracts of weed were used for treatment. The differential inhibitory effect was observed for two weed plants on two tested crops. The experimental results revealed that in case of pot culture experiment, lowest germination percentages (40.8±0.49%, 63.6±0.60% and 83±0.78%) were recorded in L. camara leaf extract treated set of A. esculentus and maximum decrease in seedling length (0.31±0.05 cm, 4.18±0.07 cm, 6.42±0.08 cm and 13.51±0.07 cm) was observed in stem extract treated a set of A. esculentus. L. camara stem and leaf extract induced a more negative effect on seedling length in both A. esculentus and V. unguiculata. For petridish bioassay experiment, lowest germination percentages (54.60±0.40%, 59.20±0.49%, 66.20±0.74% and 69.80±0.38%) were observed in L. camara leaf extract treated a set of A. esculentus. In V. unguiculata, lowest germination percentage (45.8±0.49%, 75.4±0. 40%, 84.4±0.25% and 89±0.32%) was observed in stem extract treated set. Maximum suppressive effect on seedling length was recorded for stem and leaf extract of C. cinereum of A. esculentus and leaf extract of L. camara and stem extract of C. cinereum of V. unguiculata.
