The present study was conducted to assess the water quality of the Lohit River at Parshuram Kund area in Eastern Himalayan region. The water samples from four different stations were collected from up and down stream for four different seasons, namely, winter, pre-monsoon, monsoon and post-monsoon. The collected water samples were analysed for different physicochemical characteristics such as water temperature, pH, Dissolved Oxygen (DO), Conductivity, Turbidity, Total Dissolved Solids (TDS), Calcium and Chloride. The highest temperature was recorded during monsoon (31.8 degree C). The water was slightly acidic to slightly basic in nature (6.8-7.4) with highest DO during winter (8.6 mg/l). Maximum turbidity and conductivity (123.6 NTU and 97.5 μmho/cm respectively) with lowest TDS (50.1 ppm) were observed during monsoon. High chloride and calcium content (12.35 mg/l and 23.3 mg/l respectively) was recorded during winter. The results showed that the water quality is being altered during different seasons which may be attributed to various infrastructure development in and around the area.","PeriodicalId":11458,"journal":{"name":"Ecology, Environment and Conservation","volume":"11 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75008519","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Singh","doi":"10.53550/eec.2023.v29i01.007","DOIUrl":"https://doi.org/10.53550/eec.2023.v29i01.007","url":null,"abstract":"Globally organic farming is well known and appreciated. Due to continuous use of synthetic fertilizers, the harmful elements enter into the food web and ultimately cause health hazard not only to human beings but also have a detrimental effect on environment. In this regard the demand for organic produce is gaining momentum for safe and healthy food. The present study explains the “Effect of rice and wheat varieties on rice equivalent yield, system productivity and nutrient uptake under organic farming in Jharkhand”. A field experiment was conducted at research farm of Birsa Agricultural University, Jharkhand with an objective to evaluate yield and nutrient uptake of rice and wheat varieties which are influenced by organic farming. The soil of experimental plot was sandy clay loam in texture having average carbon (6.16 Kg/ha), nitrogen (254.78 kg/ha), phosphorous (39.59 Kg/ha) and potassium (208.26 Kg/ha) with soil pH 6.04. Field experiments were carried out using randomized block design replicated thrice involving twelve treatments with twelve varieties. Rice varieties are: T1: Birsa vikas Dhan 203, T2: Birsa Dhan 201, T3 : Birsa vikas Sugandha 1, T4 : B.V.D 110, T5: Sahbhagi, T6: Birsamati, T7: Anjali, T8: Lalat, T9: M.T.U. 1010, T10: Akshay, T11: Pusa Sugandha and T12: Naveen. Whereas, wheat varieties are : Raj 4250, GW 366, NW 2036, K 0307, K 9107, HI 1563, Raj 4229, DBW 14, WR 544, BG 3, HD 2733 and DBW 39. Results showed: both the grain yield (40.22 kg/ha) and straw yield (62.96 kg/ha) of rice were maximum in MTU 1010. Likewise, the grain yield (31.56 kg/ha) and straw yield (45.78 kg/ha) of wheat were maximum in K 0307 and Raj 4229 respectively. The best rice equivalent yield of wheat was found maximum (33.19 q/ha) in B.V.D. 110-K 0307 cropping system, both the system productivity (66.52 Rs./ha) and system production efficiency (28.18 kg/ha/day) were highest in MTU 10101-WR 544 rice-wheat cropping system. Highest nutrient uptake in grain (N-53.33 kg/ha, P-11.31 kg/ha and K-10.20 kg/ha) and in straw (N-37.77 kg/ha, P-7.42 kg/ha and K-71.53 kg/ha) were observed in MTU 1010 rice variety. K0307 recorded highest nutrient uptake in wheat grain (N-47.93 kg/ha, P-8.74 kg/ha and K-10.06 kg/ha), however nutrient uptake in wheat straw (N-24.41 kg/ha, P-6.84 kg/ha and K- 38.40 kg/ha) was obtained maximum in Raj 4229.","PeriodicalId":11458,"journal":{"name":"Ecology, Environment and Conservation","volume":"88 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78297741","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It was observed that as the pH value increased, the removal efficiency increased to some time and later became constant in case of Sugarcane Bagasse at adsorbent dose of 0.5g/100 ml at contact time duration of 75 minutes. The removal efficiency decreased with gradual increase in initial fluoride concentration due to the capacity of adsorbent materials.

It is the third largest crop remanant obtained from the agriculture after sugarcane bagasse and maize straw. Storage of the surplus paddy straw, removal of entire straw from the field and very little time between the cultivation of the next crop are the major issues associated with paddy straw. Thus, stubble burning is a quickest, cheapest and easiest way to prepare field for the next crop. Burning of paddy straw results in extensive impact on both on and off farm, e.g., killing of useful microflora and fauna of the soil, losses of soil organic matter and contribution to harmful greenhouse gases including their harmful effects on human and animal health. Therefore, paddy straw burning is a major issue of environmental pollution also. Hence, need of the hour is to provide environment friendly alternatives to paddy straw instead of burning in open field. Paddy straw can be used as a source of energy, mulching material, biofuel, industrial raw material, fodder for animals, etc.","PeriodicalId":11458,"journal":{"name":"Ecology, Environment and Conservation","volume":"91 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75734352","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Commercially available machines are high capacity, more cost of operation and not affordable to the small and marginal farmers.

Data of fish caught by fisheries co-operative society Chilt Thera during September 2013 to December 2016, has been included in this study. Area of operations have also been fixed for different co-operatives by the state department of fisheries, for administrative reasons. Gill nets were applied during afternoon hours and collected next morning. Only licensed fishermen are allowed to catch the fish. Fishermen hand over their catch to their concerned co-operative which further sells the fish to the concerned contractors at the already fixed price. Close season was observed for two months during monsoon season every year, for fish conservation. Cirrhina mrigala was very less in catch (8 individuals weighing 20 kg). Labeo calbasu was not in catch of this co-operative, during this period. Catch of Ctenopharyn godonidella was very less. Fish catch was dominated by the Hypophthalmichthys molitrix (silver carp) and Cyprinus carpio (Common Carp). H. molitrix have got accidently entered in the reservoir.
