Abstract


A field experiment was conducted during Kharif on lateritic soil of Botany Farm, College of
Agriculture, Dapoli in Konkan region of Maharashtra to study the effect of lime, zinc and
boron on soybean yield and available nutrients in soil during crop growth. The experiment
was laidout in Randomized Block Design with three replications. The treatments consisting
two levels of liming i.e. ½ LR and 1 LR in combination with soil and foliar application of Zn and
B in their combinations. The results of the experiment showed significantly increased the
grain (25.52 q ha-1) and straw (37.29 q ha-1) yield of soybean due to application of 1 LR+ Zn +B
through soil and foliar spray along with RDF. The available major as well as secondary
nutrients at grand growth period and at harvest of soybean significantly recorded highest
values of available N, P2O5,K2O and S exchangeable Ca and Mg and available S with treatment
RDF +1 LR + Zn and B through soil and foliar spray, closely followed by application RDF +1
LR + B through soil and foliar spray.
