Abstract
A field experiment was conducted during summer (February-May 2001) at an experimental farm of Annamalai University, Annamalai Nagar, Tamil Nadu, India, to study the effect of integrated nutrient management practices on crop nutrient uptake and yield of finger millet (Eleusine coracana) cv. CO13. The treatments were: T1- RDF NPK (60:30:30); T2- RDF NPK + 12.5 tonnes farmyard manure (FYM)/ha; T3- RDF NPK + 5 tonnes vermicompost/ha; T4- RDF NPK + 2 kg Azospirillum/ha; T5- RDF NPK + 12.5 tonnes FYM/ha + 2 kg Azospirillum/ha; T6- RDF NPK + 5 tonnes vermicompost + 2 kg Azospirillum/ha; T7- RDF NPK + 2 kg Azospirillum/ha + 2 kg phosphobacteria; T8- RDF NPK + 12.5 tonnes FYM + 2 kg Azospirillum/ha + 2 kg phosphobacteria/ha; T9- RDF NPK + 5 tonnes vermicompost + 2 kg Azospirillum/ha + 2 kg phosphobacteria/ha; T10- RDF NPK + 2 kg Azospirillum/ha + 2 kg phosphobacteria/ha + 0.125% chelamin foliar spray; T11- RDF NPK + 12.5 tonnes FYM/ha + 2 kg Azospirillum/ha + 2 kg phosphobacteria/ha + 0.125% foliar spray; and T12- RDF NPK + 5 tonnes vermicompost/ha + 2 kg Azospirillum/ha + 2 kg phosphobacteria/ha + 0.125% chelamin foliar spray. Among the twelve treatments, T12 recorded the highest crop nutrient uptake and yield. Results revealed that integrated use of inorganic fertilizers with vermicompost, biofertilizer and foliar application of chelated zinc resulted in an additional beneficial effect over the sole application of inorganic fertilizers. It is suggested that integrated nutrient management technique hold promise as an appropriate technology for achieving higher yield in finger millet.
