Abstract

Pulses are integral to Indian agriculture due to their numerous benefits in sustainable farming practices. The continuous cultivation of the same crops has led to soil degradation and pulses can help restore soil health by enriching it with nitrogen. Prolonged use of inorganic fertilizers not only deteriorates soil structure and health but also contributes significantly to environmental pollution. Foliar applications of liquid organic fertilizers like seaweed extract, panchakavya, jeevamrutha, amirthakaraisal and mango leaf extract stimulates plant growth, yield and metabolic activity. To evaluate the effectiveness of these organic formulations, a field study was conducted at the organic farm of Krishna College of Agriculture and Technology, Madurai, during the Kharif season of 2024. The field experiment with seven treatments were carried out in randomized block design and replicated thrice. Growth, yield characters, yield and economics were recorded and worked out for each treatment. Among the treatments, foliar application of seaweed extract resulted in higher growth, yield attributes, yield and maximum net return with B:C ratio.
