Foliar Application of Nutrient and Hormonal Consortia Boost-up the Growth Parameters in Greengram Plants

Abstract

Aim: To understand the influence of nutrients and plant growth regulators on growth attributes of greengram. Study Design:  Factorial and randomized complete block design. Place and Duration of Study: Wetland farms, Department of Agronomy, Tamil Nadu Agricultural University, Coimbatore; April - June 2023. Methodology: A field experiment was conducted on clay soil fields located at Wetlands farm, TNAU, Coimbatore. Two greengram varieties CO 8 and VBN 4 were taken for the experiment. The treatments were Control – Water spray (T1), Nutrio-hormonal consortia 1 (T2), Nutrio-hormonal consortia 2 (T3), Pulse consortia 1 (T4), Pulse consortia 2 (T5). The treatments were applied as foliar spray at flowering stage of the crop. The observations are recorded after 10 days of spraying. Growth parameters were recorded. Two-way ANOVA was used to analyze the data. Results: The significant difference between the treatments was observed at p < 0.05. Foliar application of Pulse consortia 2 (T5) resulted in higher growth attributes such as leaf area, leaf area index, leaf area duration, specific leaf weight and crop growth rate in both the greengram varieties and resulted in improved growth attributes over control. Conclusion: The present study concluded that foliar application of the Pulse consortia 2 (T5) exhibit highest growth attributes in greengram. Improved growth parameters might attribute to improve the yield.
