Abstract

A field experiment was carried out at the southern farm of Karunya Institute of Technology and Science, Coimbatore during Rabi season 2022-2023 to study the utilization of leaves and leaf extract of trees for eco-friendly Vrkshayurvedic farming in greengram (Vigna radiate L). Vrikshayurvedic farming in pulses reduces the needs of harmful and unhealthy chemical fertilizers and pesticides, hence contributing to the sustainable agricultural farming. This experiment involved nine different treatments, each with varying combinations of GLM and tree leaf extracts. These different green leaf manures were used in this experiment (Albizia lebbek, Pongamia pinnata, and Delonix regia), applied at a rate of 2 t/ha as basal nutrition in the main plot. The tree leaf extracts of Moringa oleifera, Morinda tinctoria, and Annona squamosa, was applied at a rate of 5% as three foliar sprays at 20, 40 and 60 days after sowing (DAS) in the sub plot, there were significant differences in the growth and yield attributes of greengram due to the different treatments applied. The plot that received Pongamia pinnata as green leaf manure with foliar spraying of Moringa oleifera recorded higher yield of 952 kg/ha, and also all yield parameters were found to be high in this treatment. Economic analysis showed that this treatment combination also had the maximum net return of Rs. 39647 ha-1 and a benefit cost ratio of 1:2.25.

Conclusion

The results indicate that the use of organic inputs, such as Pongamia pinnata and foliar sprays of Moringa oleifera or Annona squamosa, not only improve the yield but also increases the profitability of greengram cultivation in irrigated condition.
