Abstract

A soil test crop response trial was conducted on Inceptisol (mixed black-typic usti- vertept) in Tamil Nadu Agricultural University farm, Coimbatore with finger millet Co. 11 (Eleusine coracone G.) and the comparative efficiency of different levels of organic and inorganic nutrients and their impact on yield, uptake and their efficiency have been studied. The effect of fertilizers indicated that grain and straw yields of finger millet were increased significantly upto 60 kg N and 20 kg P,O./ha. while K application had no significant influence on grain yield Organic manure incorporation enhanced the yield. The uptake was also enhanced considerably by the application of organic and inorganic nutrients. Added fertilizer nutrients and its positive effect in enhancing the fertilizer use efficiency recovery and economy were weli manifested at lower levels, while organic nutrients showed such effect only at higher evels of nutrients.
