BIOCHAR AMENDMENT ALLEVIATES CADMIUM IN CONTAMINATED SOIL AND IMPROVES NUTRIENT UPTAKE IN RICE (Oryza sativa L.)
(ACS Publisher, 2020) Devanand; Pramod Kumar Sharma; Vipin Kumar; Sarvajeet
Cadmium is a toxic metallic element that, if present in high concentrations in soil, poses severe human health risks through intake of contaminated agricultural produces. A pot experiment was conducted in a net house to assess nutrient uptake by rice (Oryza sativa L.) in cadmium-contaminated soil amended with biochar. Six cadmium levels (0, 20, 40, 60, 80 and 100 mg kg-1) and three levels of biochar @ 0, 20 and 40 t ha-1, respectively, were taken. Results indicated that nutrient content and its uptake decreased with increasing levels of soil cadmium. Nutrient content and its uptake were significantly high in soils amended with biochar. Also, the nitrogen and phosphorus contents and their uptake were more in grains; whereas potassium content and its uptake were more in rice straw. Biochar may be used to alleviate the toxic effect of cadmium in cadmium contaminated soils. © 2020, ACS Publisher. All rights reserved.
Effect of biochar augments on various growth attributes of rice (Oryza sativa l.) in cadmium contaminated soil
(Editorial board of Journal of Experimental Biology and Agricultural Sciences, 2020) Devanand; Pramod Kumar Sharma; Vipin Kumar; Sarvjeet
Anthropic actions like quarrying, transportation, agriculture, industrial waste disposal etc. discharge inorganic pollutants in great concentrations that are toxic to natural ecosystems. Heavy metal like cadmium is a toxic metallic element that poses serious human health hazards through consumption of contaminated agricultural produces when present in high concentrations in soil. To address this problem this experiment was conducted in 2018 to study the effect of biocharon growth, yield and quality of rice (Oryza sativa) in cadmium contaminated soil in the net house. Six cadmium levels (0, 20, 40, 60, 80 and 100 mg/kg) with and without two levels of biochar viz., @ 20 ton/ha and 40 ton/ha respectively were taken as treatment. Plant height, chlorophyll content, panicle length, number of tillers hill-1, productive tillers hill-1, grains panicle-1, harvest index, grain yield, straw yield, protein content and protein yield in rice were recorded. Results of current study indicated that cadmium had negative impact on growth, yield and quality parameters of rice. Growth, yield and quality of rice significantly decreased with increasing doses of cadmium in soil. Results obtained from the experiments also revealed that addition of biochar significantly increased these parameters of rice. In general, the application of biochar has shown the ability to reduce the toxic effect of cadmium on growth, yield and quality of rice. © 2020, Editorial board of Journal of Experimental Biology and Agricultural Sciences.

Organic Amendments Application Increases Yield and Nutrient Uptake of Mustard (Brassica Juncea) Grown in Chromium-Contaminated Soils
(Taylor and Francis Inc., 2020) Vipin Kumar; Pramod Kumar Sharma; Hanuman Singh Jatav; Satish Kumar Singh; Ashish Rai; Surya Kant; Achin Kumar
A pot experiment (Net House) study was conducted in the Department of Soil Science and Agriculture Chemistry, Institute of Agricultural Science, B.H.U. Varanasi to find out the effect of organic amendments in mustard grown in chromium (Cr)-contaminated soil during 2015–16 and 2016–17. There were five levels of Cr (Control, 20, 40, 60 and 80 mg/Kg soil) with and without three organic amendments (viz. Vermicompost (VC), FYM, and Sewage Sludge (Sl)) @ 5 t/ha, 10 t/ha and 20 t/ha, respectively. The maximum number of siliqua/plant (333 and 354), length of siliqua (5.43 and 5.53), number of seeds per siliqua (12.11 and 12.39), dry matter accumulation (50.76 and 54.65g/pot), biological yield (266.51 and 273.34g/pot), seed yield (62.63 and 66.96g/pot), stover yield (203.88 and 206.38g/pot), and harvest index (23.50 and 24.5%) were recorded when Cr-contaminated soil is treated with organic amendments mainly with vermin compost during 2015–16 and 2016–17. It is reported that significant nutrient uptake (N, P, S, K, Fe, Cu, Zn, and Mn) also increased with the application of organic amendments. It is reported that yield attributing characters are improved by the application of VC followed by farm yard manure then sewage Sl. © 2019, © 2019 Taylor & Francis Group, LLC.
Spatial variability map of micronutrients in vegetable growing area of Varanasi
(Action for Sustainable Efficacious development and Awareness, 2022) Kshirod Chandra Sahoo; Pramod Kumar Sharma; Rajeswari Das
Soil pH and the availability of essential micronutrients is a deciding factor for vegetable production. Major nutrients i.e. nitrogen, phosphorus, potassium, micronutrients are critical elements in enhancing vegetable growth and productivity. The present study focused on the micronutrient status of a vegetable growing area i.e. Shanshahpur village of Varanasi, Uttar Pradesh, India. Spatial variability maps were prepared from 50 samples collected from individual vegetable intercropping system from farmer’s field for all the micronutrient element i.e. Fe, Mn, Zn & Cu respectively. Most of the soils of the vegetable growing area of Shanshahpur were alkaline (7.99-8.72) in nature and lies within a safe range of electrical conductivity (<0.20 dSm-1). However, a medium range of soil organic carbon (0.50-0.75%) status was observed throughout the area. According to the variability map for micronutrient status there was a medium to high status for available Cu (0.81 mgkg-1) but in contrast available Fe and Zn content of the vegetable growing lies in low status category(2.00-13.15mgkg-1 and 0.02-2.26 mgkg-1 respectively). Available Mn status was seen reduced with increased alkalinity (9.08-0.74 mgkg-1). But most of the micronutrients were deficient for vegetable production because maximum number of soil samples lies in alkaline category which throws a scope towards amelioration of the vegetable growing soils for reducing its pH. © 2022, Action for Sustainable Efficacious development and Awareness.
