Effect of different organic sources of nutrients on growth parameters of organic summer green gram

This scientific study aimed to assessment of different organic sources of nutrients for organic summer green gram cultivation. A field experiment was conducted during summer season of the year 2020-21 on organic certified plot A-7 at Agronomy Farm, B. A. College of Agriculture, Anand Agricultural University, Anand. Different sources of organic manures were tested using randomized block design with four replications. The study revealed that different organic sources of nutrients remained not changed to plant population and they had no significant influence on plant population. In growth attributes, treatment T10 (50% N through neem cake followed by Seed treatment of Rhizobium) at 30 DAS and T8 (50% N through vermicompost followed by Seed treatment of Rhizobium) recorded significantly higher plant height at 60 DAS and harvest as compared to other treatments, respectively. Significantly higher dry weight of nodules was obtained with the application of treatment T4 (100% N through vermicompost). Higher number of branches/plant at 60 DAS and at harvest was obtained with the application of treatment T10. Higher values recorded as a result in these treatments due to microbial activities, which enhance vegetative growth and nodule formation in the plant.
