Abstract

A field experiment was conducted during summer season of 2023 to study the “Influence of organic sources of nutrients on growth and yield of cluster bean (Cyamopsis tetragonoloba L.) var. MDU1” at Research Institute on Organic Farming experiment block, University of Agricultural sciences, GKVK, Bengaluru. Thirteen treatments with different organic manures as sole source of nutrients and their combinations were tested. They were replicated thrice in a randomized block design with a spacing of 45 cm × 30 cm. Standard practices were followed during the entire course of the investigation. Among different treatments, application of 100 percent N equivalent poultry manure recorded significantly higher in growth characters (viz., plant height at 30 DAS (19.29 cm), 60 DAS (56.46 cm), 90DAS (104.72 cm), number of branches per plant at 30 DAS (6.06), 60 DAS (13.97), 90 DAS (20.62), leaf area at 60DAS (25.53 cm2), plant spread per plant at 60 DAS (36.56 cm2) and total chlorophyll content in leaves at 60 DAS (3.06 mg/g) and yield components (viz., number days to first flower initiation (27.68), number of cluster per plant (19.95), pod length (13.45 cm), weight of pods per plant (201.30 g) and pod yield per hectare (149.11 q/ha) over all other treatments.
