Type: article
Abstract: A field experiment was conducted during kharif 2015-16 at Mulmuthla village of Dharwad taluk in Dharwad district, Karnataka, India. Research conducted to study the effect of enriched FYM and vermicompost and nitrogen levels on yield and majornutrient uptake of maize (Zea mays L.) in a Vertisol. The split plot design with four replication and twelve treatment combinations. Application of nitrogen at 200 kg ha-1+ Zn+Fe enriched vermicompost at 2.5 t ha-1 was found superior in terms of grain yield (79.93 q ha-1), stover yield (88.77 q ha-1) and test weight (100 seeds) (39.67 g) over other treatments. Similarly, the highest NPK uptake (232.33, 48.73 and 175.59 kg ha-1) was recorded with the application of 200 kg N + Zn+Fe enriched vermicompost at 2.5 t ha-1. So the study of effect of different combinations of nutrients like nitrogen, enriched FYM, FYM, enriched vermicompost, vermicompost and their interactions over yielding ability of maize can help in developing a best source of nutrients for maize yield and uptake.
