Sustainable and eco-friendly seaweed influence on plant growth and Physiological Activity of pigeon pea

Seaweeds, namely, Sargassum myriocystum, Caulerpa racemosa and Gracilaria edulis, were used for seed treatment (dry and wet) and foliar application in the case of pigeon pea. Among the treatments, seeds infused (wet seeds treatment) with Sargassum myriocystum (1%) for 3 h along with a foliar spray of seaweed extracts (5%) recorded higher field emergence, growth, relative growth rate, leaf area index and duration, total chlorophyll pigment, crop growth rate and net assimilation rate
