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.

Present study was carried out to determine the important physico chemical parameters of water of Tapi estuary in Hazira industrial area. Tapi estuary receives the inputs of organic matter and nutrients coming from the domestic wastewater discharges from Surat City, a textile hub as well as industrial effluents from Hazira, a major industrial Complex of Gujarat, India. Uncontrolled discharges of domestic wastes and industrial effluents have affected the estuary. Present study was carried out from June - 2011 to May 2012 to study the impacts of uncontrolled discharges on physicochemical characteristics of water. Samples were collected monthly in the morning during low tide to determine the important physico chemical parameters Viz. Turbidity, conductivity, total solid, total dissolved solid, salinity, pH, dissolved oxygen, BOD, COD, Calcium, chloride, sodium , potassium and nutrients like nitrate, nitrite and phosphate. Dissolved oxygen was found extremely low during the study period. High biochemical oxygen demand (BOD) and Chemical Oxygen demand (COD) showed that the water quality of estuary has been affected by industrial and domestic effluents.

Water pollution caused by leather industrial effluent discharges has become a troublesome phenomenon due to its negative impact on environmental health and safety. In this paper, the wastewater in the vicinity of Lawdar tannery areas was assessed in two years from October 2019 to June 2021 to determine physico-chemical parameters of industrial effluents of Lawdar tannery at four different area points. Tannery effluents were collected and all samples were analyzed in the laboratory and rated as no freshwater with parameters such as acidity and basicity, temperature, electrical conductivity, total dissolved solids, total suspended solids, chemical oxygen demand, biological oxygen demand, color, turbidity, hardness, alkalinity, and several positive and negative ions. The investigation showed that all physico-chemical parameters were higher than the standard disposal limits of discharged water quality. The findings of this research will assist the government and tanneries in the treatment of wastewater before discharging to the environment and monitoring the dump sites with regards to disposal arrangement of the tannery effluents and environmental assessment.

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.

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.

Abstract Background Despite the favorable geo-climatic potential of Cameroon, the national production of tilapia remains low due to poor tilapia growth reported by fish farmers. One of the underlying reasons is the early female maturation at a very small size and precocious breeding in earthen ponds, resulting in overpopulation which leads to stunted growth and therefore to the production of unmarketable fish size. Studies have shown that dietary supplementation of G. kola enhanced growth in young Clarias gariepinus and Oreochromis niloticus. It was also reported that G. kola inhibited spawning in Tilapia adult females. Therefore, this study sought to assess the effects of Garcinia kola as growth promoter and inhibitor of gonadal development in young Oreochromis niloticus. Methods A total of 108 juveniles weighing 13.32 ± 0.62 g were randomly distributed in 9 hapas of 12 fishes each (9 females and 3 males) and fed for 70 days with three isonitrogenous diets, 40% crude protein with increasing Garcinia kola supplementation levels of 0 (normal diet), 6% and 10% (experimental diets). Physico-chemical parameters of the water (temperature, dissolved oxygen, pH, nitrate, nitrite, ammonia, and transparency) were measured twice a week. Every 14 days, fish were harvested, counted, and weighed. At the end of the experiment, three fish of each sex per replicate were sacrificed and their gonad and liver collected and weighed. Data were statistically analyzed using one-way analysis of variance repeated measure followed by Newman-Keuls multiple tests. Results The results showed that all physico-chemical parameters of the water were within the recommended values for Tilapia culture. Tilapia fed 6% Garcinia kola supplemented diet displayed higher final body weight in males (38.60 ± 3.50 g) and females (36.77 ± 3.62 g) compared to those receiving normal diet (36.23 ± 1.36 g and 25.87 ± 3.32 g; respectively to the final body weight in males and females). The gonadosomatic index and hepatosomatic index indicated no significant variation in males while in females, these were significantly low in the experimental fish compared to control fish. Conclusion The results of this study demonstrated that supplementation of G. kola seeds in diets of young Tilapia improved growth performance and impaired gonadal development in females.
