Abstract: An experiment to evaluate influence of crop management practices on yield and economics of high zinc ricewas conducted at Research cum Instructional farm, I.G.K.V., Raipur, during kharifseason of 2013. The experiment was laid out in factorial randomized block design with four replications. Treatment comprised of three spacing viz.,10cm x 10cm, 15cm x 10cm and 20cm x 10cm and three levels of nutrient viz., 50%, 100% and 150% RDF. The result revealed thatspacing of 20cm x 10cm recorded higher panicle length, panicle weight, number of total grains/panicle, number of filled grains/panicle, test weight, grain yield, harvest index,gross return, net return and B:C ratio as compared to15cm x 10cm and 10cm x 10cm spacing.While higher number of panicle/m2 and straw yield were recorded under 10cm x 10cm spacing. Among the different nutrient levels, application of 150 per cent RDF produced the highest number of panicle/m2, panicle length, panicle weight, number of total grains/panicle, number of filled grains/panicle, test weight, grain yield, straw yield and harvest index. Nutrient levels were not found significant with respect to B:C ratio.
