Abstract

A field experiment was conducted for two consecutive years (2011-2012 and 2012-2013) on fine texture soils of Agricultural College Farm, Bapatla to find out the effect of different sources of nutrients on secondary (Ca and Mg) and micro nutrient (Fe, Mn, Cu and Zn) uptake by rice at various growth periods. The experiment was laid out in a randomized block design in kharif season with four treatments and replicated five times. The treatments consisted of M1 (RDF- Control), M2 (10t FYM ha-1 + RDF), M3 (1.5t vermicompost ha-1 + RDF), M4 (Green manuring + RDF). The nutrient content in rice at various growth periods was significantly increased with the application of 100% NPK in combination with FYM @ 10t ha-1. However, it was on par with that of green manuring together with 100% NPK during both the years of the study.
