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

Seaweeds, namely, <em>Sargassum myriocystum, Caulerpa racemosa </em>and <em>Gracilaria edulis, </em>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 S<em>argassum myriocystum </em>(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

本研究以<em>鼠尾藻（Sargassum myriocystum）、总状蕨藻（Caulerpa racemosa）</em>及<em>江蓠（Gracilaria edulis）</em>三种海藻为试验材料，用于木豆的种子处理（涵盖干处理与湿处理两种方式）及叶面喷施处理。其中，采用1%浓度的<em>鼠尾藻（Sargassum myriocystum）</em>浸渍湿种3小时，并配合5%浓度海藻提取物进行叶面喷施的处理组合，可实现更优异的田间出苗率、植株生长态势、相对生长率、叶面积指数与叶面积持续期、总叶绿素含量、作物生长率及净同化率。
