The Bureau of Indian Standard (BIS, New Delhi) has framed a set of standards for drinking water description (IS 10500:1991-http://www.india water porta l.org), which has specifications drawn up in 1983 with the most current amendment (July, 2010), and the US Environmental Protection Agency (USEPA 2003) has also developed policy for different drinking water disinfection by-products (DBPs). This study examined the quality of metropolitan drinking water by monitoring the physicochemical parameters, and DBPs study such as the effects of halide ions, natural organic matter, and drinking water characterization were investigated. The sampled water had halo phenols DBPs as a result of disinfection, during chlorination. The water was alkaline in nature, and the water temperature varied from 33 to 37 °C. The major ions, namely bromate, iodate, chlorite, chromate, sulfate and phosphate, have been investigated in the municipality drinking water, Tiruchirappalli and Srirangam in Tamil Nadu, India. Here, three solvents such as hexane, petroleum ether and pentane were used for the liquid-liquid extraction of target compounds. The gas chromatographs equipped with capillary columns (DB-WAX) were employed for the determination of DBPs and 2-bromo-4-chlorophenol was predominantly identified.
This study examined the effect of soil fertility and Integrated Plant Nutrition System (IPNS) on the yield of barnyard millet (var. MDU 1) on the field of Eastern Block Farm in Tamil Nadu Agricultural University. Coimbatore. based on the inductive technique (fertility gradient concept). Among the three fertiliser strips, the first phase of the experiment involved adding graded fertilisers and growing fodder sorghum as a gradient crop to develop soil fertility variations. During the second phase, the barnyard millet test crop experiment included four levels each of N, P2O5, and K2O fertilizers, plus three levels of farmyard manure (FYM). The results show that overall yield recorded in the highest initial fertility strip III. The highest yield of 2966 kg ha-1 was obtained with 60:30:40 kg ha-1 of N, P2O5, and K2O along with 12.5 t ha-1 of FYM in strip II with initial soil available NPK status 198, 31, and 521 kg ha-1, respectively. The lowest yield 1056 kg ha-1 was recorded in strip I under absolute control and the initial soil test values were 157, 13 and 470 kg ha-1 of KMnO4-N, Olsen-P and NH4OAc-K, respectively. Application of 12.5 t ha-1 of FYM alone increased yield of barnyard was 27.73 per cent over absolute control. Barnyard millet grain production and NPK uptake rose when initial soil fertility and fertiliser N, P2O5, K2O, and FYM levels increased.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
