Abstract Purpose Present work aims at studying the influence of active (using external aerator) and passive (natural) aeration on composting of household biodegradable wastes. Methods To study the suitability of these reactors to household conditions, continuous loading was carried out for a period of 60 days. Both the reactors were loaded with cooked as well as raw vegetable and fruit waste. Physico-chemical parameters such as temperature, pH, C/N ratio, moisture content, total organic content, Total Kjeldahl Nitrogen and seed-germination parameters such as Germination Index (GI) and Root Length Index (RLI) of the mulch were analyzed at different stages of the composting process. Results Results confirmed that, although both types of aeration seem to have performed well under continuous loading, the maturation period required for actively aerated reactor was 37.30% lesser than that of naturally aerated reactor. Conclusion Active aeration found to be more suitable to household conditions as odor and fly nuisance was relatively less.

In order to investigate the comparative analysis of physico-chemical parameters of experimental soil (black cotton soil), vermicompost, farmyard manure and their impact on seed germination, the study was conducted by using Randomized block design (RBD) with three replications at the Department of Botany Govt. Madhav Science P.G. College Ujjain, M.P. The various physico-chemical parameters (pH, electric conductivity, organic carbon, nitrogen, phosphorus, potassium, zinc, copper, iron, and manganese) and seed germination of soybean and wheat were studied in the experiment. The results revealed that pH (7.14), electric conductivity (1.84 ds/m), organic carbon (198.53 g/kg), nitrogen (246.57 kg/ha), phosphorus (55.24 kg/ha), potassium (438.52 kg/ha), zinc (320.13 ppm), copper (289.34 ppm), iron (239.34 ppm) and manganese (248.37 ppm) were found more efficient in vermicompost followed by farmyard manure and soil. The results also revealed that seed germination percentage of soybean was found highest (91%) by using 20% vermicompost followed by 20% farmyard manure (86%), 200 gm NPK (73%) treatment, control (69%) and seed germination in wheat was maximum (93%) in 20% vermicompost treatment followed by 20% farmyard manure (87%), 200 gm NPK (74%) and minimum (70%) in control. The study concluded that vermicompost is nutrient rich and most efficient organic manure than farmyard manure and NPK fertilizer for the better growth and sustainable agriculture of soybean.

Germination And Growth

Textile industrial effluents are highly polluted in nature and vary in its compositions. In the adjoining agricultural area of textile industries sector, there is immense degradation of crops productivity being contaminated by irrigation through tubewells or directly from the effluent drain or village pond. The present paper deals with the physico-chemical parameters of textile industrial effluents and its impacts on germination and growth performance of Lentil (Masoor) Lens esculentum, (Family: Leguminoceae, Sub-family: Papillionateae). Seeds were found more tolerant against 25% concentrated effluent.

The article presents the results of studies of osmolality and pH of 0,9 % sodium chloride of various manufacturers. To obtain data on the pH value, the data used in the passports are used, and the indicators of its osmolality are de- termined using laboratory tests. 0,9 % sodium chloride from different manufacturers has different pH and osmolality. Knowing the actual values of physico-chemical parameters can increase the accuracy of the results of future clinical studies, which compare the pharmacokinetics and pharmacodynamics of modern plasma-substituting solutions and a solution of 0,9 % sodium chloride.
