| dc.description.abstract | Three field experiments were conducted during rabi season of 2013-14 at N. E. Bourlag Crop Research Centre of Govind Ballabh Pant University of Agriculture & Technology, Pantnagar, (Uttarakhand), to study the effect bio based nano materials of gypsum and rock phosphate on phenology, morphology, physiology and yield of wheat and on soil microbes. The experimental site was sandy clay loam, and had organic carbon (0.72%), available nitrogen (216 kg/ha), available phosphorus (22 kg/ha) and available potassium (133 kg/ha). The soil reaction was slightly alkaline (pH 7.3). The wheat variety UP-2526 was used as test crop. Three sets of experiment having six, twelve and twelve treatments were laid down in randomized block design with three replications. In, first set of experiment the treatments were control, 50% RDF, 100% RDF, 125% RDF, 50 & 100% RDF applied with bio based nano materials. In second and third set of experiment RDF @ 50 % and 100 % were tested with different combinations of five biological based formulated nano minerals of gypsum (second experiment) and rock phosphate (third experiment) . The formulated nano minerals were clay based, parthenium based, FYM based, neem based, Vegetable peel based formulation of nano gypsum and nano rock phosphate. Results of first experiment revealed that plant height, dry matter accumulation, SPAD reading, green seeker value and grain yield obtained at 50% RDF with bio based nano materials, was statistically similar with 100% RDF. In experiment second, Tillers/m2, SPAD value, leaf area index, yield, and economics (gross return, net return, B: C ratio) observed highest under 50% RDF applied with clay based nano gypsum. In experiment third, Tillers/m2, dry matter accumulation, leaf area index, green seeker value, straw yield and bio logical yield observed highest under 50% RDF applied with vegetable peels based rock phosphate. From these experiments, it could be concluded that wheat crop performed better under 50% RDF applied with bio based nano materials, or 50% RDF applied with clay based nano gypsum or 50% RDF applied with vegetable peels based nano rock phosphate as compared to RDF without nano minerals. Therefore, we can save 50 % of our recommended fertilizer dose. | en_US |
