(Springer, 2021) Sandeep Kumar Tripathi; Babloo Sharma; Pratibha Kumari; Proloy Deb; Ratneswar Ray; Anjelo Francis Denis
An experiment was carried out during 2011 and 2012 at the Gangetic alluvial soils of West Bengal, India to assess the impact of four irrigation schedules and three nutrient sources on productivity, quality, water use efficiency (WUE) and economics of turmeric. The results showed that maximum yield was observed due to the main effects of irrigation schedule at 0.9 irrigation water (IW)/cumulative pan evaporation (CPE), nutrient schedule at 50% recommended dose of fertilizer (RDF) + 25% farmyard manure (FYM) + 25% vermicompost and their interactions at harvest stage during both years. The higher fresh (24.61 and 26.81 t ha−1) and cured (5.12 and 5.23 t ha−1) rhizome yield during both years, respectively, were registered under 0.9 IW/CPE with 50% RDF + 25% FYM + 25% vermicompost. The WUE was higher under 0.9 IW/CPE with 50% inorganic + 25% FYM + 25% vermicompost, resulting in a considerable increase in turmeric yield during both years. The irrigation and nutritional schedules (0.9 IW/CPE with 75% RDF + 25% FYM) had significantly higher return per rupee investment than other treatments. This study confirmed that application of irrigation at 0.9 IW/CPE and combine application organic and inorganic nutrient sources improved rhizome yield, WUE, quality and return per rupees investment, could be obtained more precisely from the knowledge of irrigation scheduling and integrated nutrient management. © 2021, NAAS (National Academy of Agricultural Sciences).
Evaluation of site suitability and storage capacity of constructed rainwater harvesting structure in Vindhyan region, India
(Ecological Society of India, 2016) Sandeep Kumar Tripathi; Babloo Sharma; P. Raha
The study was under taken to evaluate the suitability of site of constructed rainwater harvesting structures. Volume of stored rainwater and area of submergence of check dam was used for the understanding the suitability of constructed site. The collection runoff water starts form July and remains up to February/March. Maximum volume of the harvested runoff rainwater and area of submergence was 24954 m3 and 30985 m2, at 1.11 m level of stored water at the check dam. There was no water during the month of April to June in the reservoir. © 2016, Ecological Society of India. All rights reserved.
Monitoring of groundwater quality with respect to fluoride contamination around Hindalco Industries Ltd. Renukut, Sonbhadra district, Uttar Pradesh, India
(Technoscience Publications, 2016) Shishu Pal Singh; Sandeep Kumar Tripathi; Vimal Kumar; Priyankar Raha
In the era of industrial advancement, fluoride is mainly contributed through runoff and leaching of phosphate fertilizers in agricultural land and liquid waste from industrial sources. Persistent use of fluoride contaminated coal in the thermal power plants and aluminium smelter plant can also heavily contribute fluoride in the groundwater. Since there are no major studies in the recent past, the present study was carried out to understand the groundwater quality in the investigated area. Groundwater samples were collected from 25 different locations around aluminium smelter plant from wells, shallow hand pump and deep hand pump during the month of June to September 2008 in Renukut district Sonbhadra for determining various parameters (pH, EC, Cl-, Ca2+, Mg2+ ,Na+, CO3 2-, HCO3-, Total Dissolved Solids, fluoride). The fluoride content in groundwater of Renukut ranged from 1.23 to 2.79 mg/L with average of 1.82 mg/L. 95% of the groundwater samples in the study area had crossed the permissible limit of fluoride in drinking water i.e., 1.5mg/L. The fluoride contamination to the groundwater during the post-monsoon season is mainly due to the seepage, moving and percolation of fluoride contaminated water nearby aluminium smelter plant and dissolution of fluoride bearing mineral under alkaline condition is the major source of fluoride in groundwater.
Performance of Turmeric and Soil Moisture Depletion Pattern Under Different Water Regimes and Nutrient Sources at New Alluvial Zone of Indo-Gangetic Plains, India
(Taylor and Francis Inc., 2018) Sandeep Kumar Tripathi; Babloo Sharma; R. Ray; P. Raha; Anjelo Francis Denis
In India, the production of turmeric is not even half compared to its potential. To analyze the possibilities for higher production in turmeric, this study was conducted at the BCKV, Gayeshpur, West Bengal, during 2011 and 2012, to evaluate the effect of irrigation scheduling (0.6, 0.9, and 1.2 irrigation water (IW)/cumulative pan evaporation (CPE) and rainfed) in main plots and nutrient management [100% inorganic, 75% inorganic + 25% FYM (Farm yard manure), and 50% inorganic + 25% FYM + 25% vermicompost] in subplots on soil moisture depletion and productivity of turmeric. The highest value of fresh rhizome yield (23.90 kg ha−1) and qualitative indices were obtained with irrigation schedule at 0.9 IW/CPE ratio water regimes and 50% inorganic + 25% FYM + 25% vermicompost. The correlation coefficients of water use and yield of turmeric were found at 0.943. The combination of 0.9 IW/CPE and 50% inorganic + 25% FYM + 25% vermicompost improved the overall performance of turmeric crop. © 2018 Taylor & Francis.
