Abstract
The present study was conducted in research plots of Central Horticultural Research station (CHES) during Rabi season 2018-2019 on Integrated Nitrogen management in chilli under lateritic soils of Odisha. The field experiment was laid out in Randomized Block Design comprising of eight treatments replicated thrice. It was observed that the substitution of N through vermicompost to the extent of 50% and remaining 50% as urea proved to be considered as the best treatment amongst different combinations of organic sources with urea (RDF). The highest yield of chilli i.e. both pod yield (14511.4 kg ha-1) and stover yield (901.05 kg ha-1) and plant growth such as plant height, flowering, fruiting, fruit length, fruit girth was observed in T5 due to combination of 50% of N as urea and 50% of N as VC. Integrated use of organic manures along with chemical fertilizers not only produced highest and sustainable crop yields but also enhanced plant growth due to quick mineralization and easy availability.
