The current study was focused on the analysis of carbon and nutrient storage of soil in various land use systems in Amarkantak region. The study was conducted during 2016-2017 and during the study the soil sample was collected from different land use system (i.e. Forest ecosystem, Grassland, Agriculture land and Pine plantation) at the depth of 0-20 cm and 20-40 cm with the help of soil auger.The status of pH ranged from 6.10 to 7.13 at 0-20 cm depth and it was recorded 6.12 to 6.98 at 20-40 cm depth, from all the different land use systems and the pH of Agriculture field was recorded maximum 7.13 at the depth of 0-20 cm, followed by Agroforestry field 6.39 at 0-20 cm depth, Grassland 6.38 at 20-40 cm and lowest was recorded 6.10 at the depth of 0-20 cm in Pine plantation. EC values ranged from 66.1μs to 349 μs in four different land uses. Maximum EC 349μs at 0-20 cm was observed in Agricultural field, followed by 337 μs in Agroforestry field at 0-20 cm depth, Grassland was recorded 214μs and minimum were found 66.1 μs in Pine plantation. The Total Dissolving Salt (TDS) and salt concentration ranged between 70.3 ppm to 271 ppm and 38.3 ppm to 271 ppm at 0-20 cm and 20-40 cm in all the different field systems, respectively. The highest quantities of Nitrogen were observed in Agroforestry system 405 kg ha-1 at the depth of 0-20 cm and phosphorus was observed in Agroforestry system and Agricultural system same value 25 kg ha-1 at the depth of 0-20 cm and 20-40 cm. The highest potassium was observed in Agroforestry system that is 280 kg ha-1 at the depth of 0-20 cm. The status of Nitrogen, Phosphorus and potassium show mixed trends regarding the cultivation practices and depth of soil in case of agroforestry system, agriculture system and pine plantation but in case of grassland system it was shows a significant difference with another systems.The highest soil organic carbon and soil organic matter was recorded maximum in pine plantation that is 2.17 % and 3.74 %, respectively at the depth of 0-20 cm followed by 1.72 % and 2.96 % in Grassland system at the depth of 20-40 cm, 1.8% and 3.09% in Agricultural system at the depth of 0-20 cm, respectively.

They are known to be highly toxic to cells, mainly through their action on cell reproduction. Many have proved to be carcinogens, mutagens or teratogens. Patients receiving therapeutic doses of these drugs have exhibited many adverse effects, including cancers. All people who came in contact with cytotoxic drug...

Student, Dept. of Home Science, University of Rajasthan, Jaipur, Rajasthan, India Kesar Chayal  Assistant Professor, Dept. of Home Science, University of Rajasthan, Jaipur, Rajasthan, India The present study was an attempt to investigate the preference of information sources by agriculture farmers. Study was conducted in Jaipur district of Rajasthan. 75 respondents were selected through random sampling method for the study and personal interview technique was used for data collection. Data related to information source used by the farmers revealed that mobile phone was the most preferred source by the farmers (70.66%). Farming helping apps (56%), television (53.33%), internet (52%) and local leader /neighbors (41.33%) always used by the farmers for accessing agriculture information. Study further revealed th...
