“…Singh et al (Wani et al, 2018a;Padder et al, 2022) also reported less spot blotch severity in early sown crop than late sown crop. The per cent seed infection depends on spot blotch disease severity and low disease severity was recorded in early sown crop plot as also reported earlier by (Bhat et al, 2017;Malik et al, 2018;Bano et al, 2022) wherein timely sown crop was less affected by spot blotch than late sown. Data regarding the individual effects of nutritional amendments (Table 1a) clarified that FYM @ 5 t/h lead to the highest values of PDI (76.50%) as well as seed infection (58.38%) followed by RDF with PDI and seed infection values of 74.93 and 50.50%, respectively.…”

Spot blotch caused by Bipolaris sorokiniana is one of the most serious diseases of barley in tropical areas where barley and wheat are grown. A field experiment was conducted at Regional Research Station Masodha, ANDUA&T, Kumarganj, Ayodhya, Uttar Pradesh during Rabi season. To evaluate the effect of different dates of sowing and chemical and organic amendments on spot blotch and consequently on seed quality of barley. The experiment was conducted during the Rabi season 2016-17 under hotspot area of spot blotch. RD-2794 was sown in a split plot manner with two dates of sowing.The experiment was performed in split plot design with three replications comprising two different dates of sowing, i.e. mid- November (D1 ) and mid-December (D2 ) in the main plot and chemical and organic amendments viz., RDF (60N:30P:20K kg/ hectare) -T1 , FYM @ 5 t/h-T2 , T1 + Mulch@ 6 t/h-T3 , T1 + FYM @ 5t/hec + Mulch @ 6t/ hec.-T4 , T4 + 2 spray of zinc sulphate @ 0.5 %-T5 , T4 + 2 spray of KCl @0.5%-T6 and T5 + 2 spray of KCl @ 0.5 %-T7 in the sub plot. Results revealed that minimum disease severity (46.9%) with maximum disease control (39.98%) and per cent seed infection (5.5%) were recorded in D1 × T7 . The interpretation of data revealed that there was highly positive and significant correlation (r=0.95) between disease severity and per cent seed infection. The maximum 1000-seed weight (43.41g) and yield (38.67 q/ha) with maximum yield gain (57.25%) was also recorded in D1 × T7 . The same treatment combination was also useful in maximizing the seed quality in terms of seed viability (98%), Germination (97%), seedling length (27.30cm) and vigour index-I (2648.153) when the freshly harvested seeds were tested in seed testing laboratory. Spot blotch is a serious disease of barley spreads primarily through infected seeds and reduced the yield up to 30%. The disease can be minimized by sowing the crop timely i.e. mid-November with recommended dose of fertilizers + FYM @ 5 t/ha+ Mulch@ 6 t/ha+ 2 spray of zinc sulphate @ 0.5 % + 2 spray of KCl @ 0.5 % at flag leaf and post anthesis stage which improves the seed quality.

“…Many scholars have studied the trace element contamination of surface water in different locations in India (Ram and Singh, 2007;Tiwari et al, 2016;Lohani et al, 2008). Trace element pollution has been assessed by the distribution of particle size and the organic content present in the water system (Saif and Khan, 2017;Bano et al, 2018;Prieto et al, 2018). The bioavailability of trace elements depends on the concentration of anions, chelating agents in the water, pH, and the presence of absorptive sediments.…”

“…The unplanned and unregulated development of urbanisation during the last two decades has resulted in the degradation of environmental health, particularly in developing countries like India (Rauf et al, 2009;Madhav et al, 2020;Bano et al, 2022). A number of anthropogenic activities may alter the dynamic properties of lotic ecosystems by adding heavy metals to the water bodies (Cortecci et al, 2009;Bhat et al, 2011;Hasan et al, 2021;Khan et al, 2022).…”

Trace elements are a major pollutant in the river water and these pollutants are present in all components of the ecological system. Since time immemorial, the River Veshaw has been one of the important sources of water and has shaped the cultural and social values in the Kashmir Valley. This study was conducted in rural parts of South Kashmir in the Western Himalaya from February to January 2020–2022. The river Veshaw provides various ecosystem services to the local communities as well as in the upper and lower stream regions in the form of many direct and indirect ecosystem services. The river is polluted by human waste from both rural and urban communities, as well as by agricultural runoff and effluent discharges from a variety of industrial activities due to its proximity. Effluent that makes it to the river contains a variety of pollutants, some of which are trace elements that accumulate in the local ecosystem, killing off plants and animals and reducing biodiversity. Trace element levels in water and sediment were found to follow the trend as: Sangam > Khudwani > Kulgam > Nihama > Aharbal > Kingwattan. The dominance pattern of heavy metals in water was Pb > As > Cd. The overall trend showed a downward trend of heavy metals, indicating the effect of land area drainage and anthropogenic activities on the stream water. The dominance pattern of heavy metals in water was Pb > As > Cd. Heavy metals were not detected in the middle and upstream sites. The average levels of heavy metals were highest at Downstream (Sangam), with values of Cd, Pd ad As 0.0054, 0.038 and 0.038 mgL-1. This shows that land drainage and human activities have an effect on the water in the stream.

“…(World Health Organization, 2008). Anthropogenic activities are degrading the world's water resources, reducing their accessibility for domestic, drinking, irrigation, shing, outdoor enjoyment, and industrial purposes (Shit, Bano et al 2022). Concerns have also been raised about the urban streams that run through these neighbourhoods being used as dumping grounds by both homes and businesses (Bhat et al, 2011;Phiri et al, 2005;Enguito et al, 2013;Sharma et al, 2020;Mihai et al, 2020;Datta et al, 2022).…”

Almost a billion people, especially in developing countries, need safe water. Several studies in India show that most drinking water sources have high coliform counts. Standard quality control is needed. This study was conducted in rural parts of South Kashmir in the Western Himalaya from February to January, 2020–2022. Water samples were taken from the river from upstream to downstream using standard water sampling techniques. The purpose of this study was to investigate the detection and molecular identification of coliforms in drinking water and the chemical water quality associated with coliform-contaminated drinking water, which summarises river water pollution. The results showed significant variation in water quality measures, indicating increased pollution levels downstream. In all seasons, the highest coliform count was recorded at Sangam (downstream) of the river. In the summer season at Sangam it was recorded (72.2600 cfu 106/l) and no coliform count was found at Kongwaton (upper stream) during the winter season near the source of the Veshaw river. In all seasons, the highest values of water quality parameters (pH 6.847, EC 71.620 dS/m, BOD 1.120 mg/l, and COD 24.637 mg/l) were recorded at Sangam (downstream) of the river during the summer season. In the winter season at Kongwaton, the lowest values of water quality parameters were pH 8.947, EC 253.680 dS/m, BOD 4.963 mg/l, and COD 51.440 mg/l. The existence of coliforms in water indicates current faecal contamination and determines the presence of disease-causing pathogens. The goal of this work is to examine the level of total coliform contamination, coliform species identification, and chemical water quality properties of drinking water and its associated factors, which implies the pollution level in the river. Total DNA was collected and sequenced for 16S rDNA and metagenomics. Universal primers were used to amplify the bacterial 16S rRNA. Using BLAST, the amplified 16S rRNA gene sequence was matched to the NCBI database. A metagenomic study found 27 species that had different relative abundances. These species include E. coli, Escherichia fergusonii, Escherichia albertii, Klebsiella grimontii, and Shigella dysenteriae. This study is thought to be the first to discriminate against E. fergusonii, Escherichia albertii, Klebsiella grimontii, and Shigella dysenteriae from E. coli and to report on E. fergusonii and E. albertii, Klebsiella grimontii, and Shigella dysenteriae in the river Veshaw water sources in Kulgam, Western Himalaya.
