Abstract

A field experiment was conducted on fine texture soils to find out the effect of different sources of nutrients on secondary (Ca and Mg) and micro nutrient (Fe, Mn, Cu and Zn) content in 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 M (RDF - Control), M2 (10 t FYMha−1 + RDF), M3 (1.5 t 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% NPKin combination with FYM @ 101 ha−1. However, it was on par with that of green manuring together with 100% NPK during both the years of the study.
