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.

Abstract

Soil-land form relationship was studied for Ayyammanahalli village by the interpretation of satellite and Google earth imagery. Sampling areas in transect were marked along the slopes based on the tonal variation. The selected transect areas were marked for profile study, five representative pedons were exposed on five different physiography, like Upland summit, Upland lower sector, Upland upper sector, shoulder of upland and lowland. The study area represents semi arid tropical climate. It has vast areas of upland and considerable area of lowland. Majority of the upland is under field crops. Upland has very gentle to gentle slope.
