| dc.description.abstract | A field experiment entitled “Effect of nano-sized gypsum on growth and productivity of Wheat (Triticum aestivum)” was conducted at the Norman E Borlaug Crop Research Centre of Govind Ballabh Pant University of Agriculture and Technology, Pantnagar (U.S Nagar) From November 2016 to April 2017. Surface Soil (0-15 cm) of the experiment field was silty clay loam in texture, medium in organic carbon (0.72%), low in available N (218.59 kg/ha), medium in available P (12.53 kg/ha) and medium in available K (149.56 kg/ha) with neutral soil reaction (pH 7.3). In addition to the field experiment two laboratory experiment entitled “Effect of nano-sized gypsum on germination of wheat” and “Effect of nano-sized gypsum blended MS media solution on seedling growth of wheat” was conducted simultaneously to investigate the effect of nano-sized gypsum on emergence and initial seedling growth more precisely. The field experiment was conducted in randomized block design with 3 replications while both the laboratory experiment was conducted in CRD each with 3 replications. For the experiment variety DPW 621-50 was used. The laboratory studies suggest that seed treatment with 100ppm nano-sized gypsum enhances germination and further seedling growth of wheat. In the field experiment it was found that 75% of RDF along with nano-sized gypsum and clay based nano-sized gypsum produced yield at par with 100 % RDF, thus saving 25 % of the RDF. Similarly among plant based nano-sized gypsum, Parthenium based nano-sized gypsum along with 75% of RDF gives promising results. High yield in nano-sized gypsum (4 t/ha), Parthenium based (3.73 t/ha) and clay based nano-sized gypsum (4.07 t/ha) was due to high photosynthetic surface i.e. leaf area index and high yield attributing characters. Hence, 75% of RDF along with nano-sized gypsum or clay based nano-sized gypsum can be recommended to the farmer. | en_US |
