Abstract
Field experiment was conducted during kharif-2011 at Zonal Agricultural Research Station, University of Agricultural Sciences, Gandhi Krishi Vignana Kendra, Bengaluru to study the effect of application of FYM, fertilizer levels and different plant population levels on seed yield, nutrient uptake and final nutrient status of soil. Results revealed that application of FYM (5 t/ha), higher plant population level of 74074 plants/ha and higher fertilizer level 133 per cent of RDF recorded significantly higher nitrogen, phosphorus, potash, sulphur, zinc and boron uptake which in turn resulted in higher seed and stalk yield in these treatments. Significantly higher build up of nutrients was noticed in lower plant population level 37037 plants/ha over initial soil fertility status.
