Abstract

The objective of the present study was to investigate the effects of different sources of organic manure on nodulation, chlorophyll content of leaves, availabilities of nutrients and soil chemical properties compared to the recommended dose of fertilizer (RDF).

The study was conducted during kharif and rabi seasons of 2022. The experiment laid out in randomized block design, replicated three times having nine treatments i.e., T1- Absolute control; T2- Vermicompost 100% on N equivalent basis; T3- Farmyard manure 100% on N equivalent basis; T4- Vermicompost 50% + Farmyard manure 50%; T5- Vermicompost 75%+Farmyard manure 25%; T6- Vermicompost 25% + Farmyard manure 75%; T7- RDF 100% inorganic; T8- RDF 50% inorganic+Vermicompost 50%; T9- RDF 50% inorganic + Farmyard manure 50%.

The results indicated that application of vermicompost at 100% nitrogen equivalent basis increased root nodulation, chlorophyll content of leaves and improved soil properties. The application of 100% RDF also enhanced the nutrient availabilities and nutrient uptake in clay loam soil.
