Sustainable nutrient management with the combination of organic and chemical fertilizer amendment expects a key part in upgrading stevia yield without harming the environment and to build up the nutrient balance with increasing soil fertility. A pot experiment was conducted in the net house of the Department of Agricultural Chemistry, Bangladesh Agricultural University, Mymensingh to study the combined effect of vermicompost (VC) and chemical fertilizer (CF) on the growth, leaf biomass yield and stevioside content of stevia in acid soil. Six combinations of VC and CF were applied following completely randomized design (CRD) with three replications. Results showed that VC along with different rates of CF exerted significant influence on the growth, leaf biomass yield and stevioside content of stevia and postharvest soil fertility. The highest values for most of the parameters were found from the plant receiving VC @ 7.5 t ha−1 along with 50% CF. About 578% higher leaf biomass yield was obtained from the treatment VC7.5+CF50 over control. Stevioside content was increased with the increasing levels of VC up to 7.5 t ha−1 along with 75% of CF and also with the advancement of growth period from 30 to 60 days after planting. The highest amount of stevioside (11.05%) was detected in the leaves of plant of the same treatment at harvest. Soil acidity was significantly decreased with the increased levels of VC and CF where as soil fertility in terms of organic matter and nutrient content was increased. Considering the overall performance, farmers may be advised to cultivate stevia in acid soil applying VC @ 7.5 t ha−1 along with 50% chemical fertilizer to boost up stevia production under the agroclimatic condition of the study area in the context of Bangladesh

Potassium (K) is an essential plant nutrient affecting most of the biochemical and physiological processes. It is classified as a macronutrient due to large quantities being taken up by plants during their life cycle. With the aim of establishing a scientific basis of K fertilization on the growth, leaf production, minimum K requirement and critical leaf K concentration of stevia, a pot experiment was carried out in the net house of the Department of Agricultural Chemistry, Bangladesh Agricultural University. Six levels of K viz. 0 (K0), 50 (K50), 100 (K100), 150 (K150), 200 (K200) and 250 (K250) kg ha-1 were used in acid and non-calcareous soils. Plants were harvested at 60 days after planting (DAP). Results showed that K application significantly influenced the growth attributes, leaf yield and other parameters. Highest values of all the parameters except K content were obtained when K was applied @ 200 kg ha-1 which was significantly different from other levels of K including control. Dry weight of stevia leaves at harvest was increased from 0.77-7.41g and 0.99-7.74g Pot-1 in acid and non-calcareous soils, respectively over control. Potassium content was directly proportional with the increased levels of K though uptake did not follow the same trend. Leaf critical K content was estimated to be ca 1.75 and 1.71% in the plants grown in acid and non-calcareous soils, respectively. The minimum K requirement for maximum leaf biomass production (80%) of stevia was estimated to be ca 220 and 199 kg ha-1 grown in acid and non-calcareous soils, respectively. This study would contribute to improve K fertilization of stevia in various types of soil. [Fundam Appl Agric 2017; 2(3.000): 297-302]

The river-water of Dhaka city is polluting day by day because of increasing level of industrialization, poor water use practice and wastewater management inefficiency. Heavy metals present in river-water are uptaken by food crops when it is used as irrigation purposes which ultimately causing health risks. A pot experiment was conducted to assess the extent of pollution of four rivers water surrounding Dhaka city and to evaluate their effects on the yield and heavy metal concentrations and their uptake by rice and cabbage. Ten water samples of each river viz., Buriganga, Shitalakshya, Turag and Bangshi were collected and analyzed. Crop growth experiment was laid out following completely randomized design with three replicates. The pH, electrical conductivity (EC), total dissolved solids (TDS) and dissolved oxygen (DO) ranged from 5.45 to 7.60, 170 to 1374 (μS cm-1), 451 to 1827 (mg L-1) and 1.8 to 6.5 (mg L-1), respectively. The highest Pb (72.5 mg L-1), Zn (675.8 mg L-1) and Cd (1.08 mg L-1) concentrations were found in Buriganga water whereas the highest Cr concentration (95.2 mg L-1) was found in the water of Turag river. The concentrations of the heavy metals in those rivers were above the permissible limit with the exception of Shitalakshya river-water. In terms of heavy metal pollution, water of four rivers were of the following order: Buriganga > Turag > Bangshi > Shitalakshya. River-water irrigation reduced the yield up to 27% for rice and 38% for cabbage compared to freshwater. The lowest yield of rice and cabbage (3.2 and 25.3 t ha-1, respectively) was found with Buriganga river-water irrigation. The highest Pb (3.72 mg kg−1), Cd (0.08 mg kg−1) and Zn (8.90 mg kg−1) concentrations in rice grain were recorded in the plants grown with Buriganga river-water, whereas the highest Cr concentration (2.34 mg kg−1) was obtained from Turag river-water irrigated rice plant. In cabbage, the highest concentrations of Pb, Cd and Zn were 4.38, 0.012 and 8.86 mg kg−1, respectively recorded from the irrigation of Buriganga river-water, whereas the highest Cr concentration (3.02 mg kg−1) was recorded from Turag river-water irrigation. The overall results suggested that the studied river-water may not be used directly without proper treatment for rice and cabbage production. [J Bangladesh Agril Univ 2020; 18(2.000): 332-339]

This review chronicles the indirect transmission method which seems to be overlooked by most people and makes attempts to document the various transmission ways with a hope that such information may strengthen the knowledge base of researchers towards methods of eradicating the pandemic. Current knowledge of transmission and exposure of SARS-CoV-2 has been explained. Various researchers have put forward different ways of exposure and transmission. Literature does not reveal whether the indirect transmission route is the dominant one. However, total lockdown could be a veritable means to reduce both direct and indirect transmission routes. In many countries where the indirect transmission has been reduced, the scourge of the virus is less. The work creates awareness on the need to watch out for those routes of transmissions that may not be popular and suggested vital knowledge gaps that need to fill.
