Abstract

A field experiment was conducted on a Typic Haplustalf with sandy loam texture to study the effect of different methods of zinc application on growth and yield of maize. Results indicated that different methods of zinc application significantly increased the grain yield and stover yield of maize compared to control except the treatment which received seed priming with one per cent zinc solution for 8 hour. However, the treatment which received soil application of zinc sulphate @ 10 kg ha^-1 recorded maximum yield of 7.52 t ha^-1 and 6.96 t ha^-1 of stover and grain, respectively.

Keywords

Abstract

A field study was carried out at College of Agriculture, Navile, Shimoga during Kharif 2009 to study the effect of integrated nutrient management practices on distribution of nitrogen fractions in soil. There were two levels of nitrogen applied through organics (FYM and vermicompost) and inorganics involving nine treatments combinations were tried in a RCBD with three replications. Significantly lower available nitrogen status was recorded in the treatments which received nitrogen only through fertilizers and without any organic matter application (196.00-200.50 kg ha^-1) including absolute control compared to all other treatments (238.00-243.60 kg ha^-1). Except inorganic nitrogen fractions, organic nitrogen fractions were recorded high in integrated treatments compared to the treatment which received nitrogen only in the form of fertilizers.

Keywords
