The usage of seaweed extracts in cropping systems is gaining attention nowadays due to their distinct bioactive properties. This study aims to assess how saffron ( L.) corm production was affected by seaweed extract through different application modes. The study was conducted at the CSIR-Institute of Himalayan Bioresource Technology, Palampur, HP, India, during the autumn-winter agricultural cycle. Five treatments using a combination of Kappaphycus and Sargassum seaweed extracts were replicated five times in a randomized block design. Treatments that were examined include T1: Control, T2: Corm dipping @ 5% seaweed extract, T3: Foliar spray @ 5% seaweed extract, T4: Drenching @ 5% seaweed extract, and T5: Corm dipping + foliar spray @ 5% seaweed extract. Seaweed extract, when applied to saffron plants (T5: Corm dipping + foliar spray @ 5% seaweed extract) resulted in significantly higher growth parameters along with the higher dry weight of stem, leaves, corms, and total roots per corm. Corm production, ., the number of daughter corms and corm weight per m was significantly affected by seaweed extract application, with the maximum value recorded with treatment T5. Biochemical parameters chlorophyll, carotenoids, and photosynthetic rate were higher in T5, while nutrient concentration was lowest in this treatment. Seaweed extracts improved corm production, making it a feasible alternative to limiting the application of conventional fertilizers, attenuating the effects on the environment, and enhancing corm number and weight.
由于其独特的生物活性特性，海藻提取物在种植系统中的应用如今正受到关注。本研究旨在评估通过不同施用方式，海藻提取物对藏红花球茎产量的影响。该研究于秋冬农业周期期间，在印度喜马偕尔邦帕拉姆布尔的CSIR - 喜马拉雅生物资源技术研究所进行。使用卡帕藻和马尾藻海藻提取物组合的五种处理，在随机区组设计中重复五次。所考察的处理包括：T1：对照；T2：球茎浸渍5%海藻提取物；T3：叶面喷施5%海藻提取物；T4：浇灌5%海藻提取物；T5：球茎浸渍 + 叶面喷施5%海藻提取物。当将海藻提取物施用于藏红花植株时（T5：球茎浸渍 + 叶面喷施5%海藻提取物），导致生长参数显著更高，同时茎、叶、球茎的干重以及每个球茎的总根干重也更高。海藻提取物的施用对球茎产量，即每平方米子球茎数量和球茎重量有显著影响，处理T5记录的数值最高。生化参数叶绿素、类胡萝卜素和光合速率在T5中更高，而该处理中的养分浓度最低。海藻提取物提高了球茎产量，使其成为限制传统肥料施用、减轻对环境的影响以及增加球茎数量和重量的可行替代方法。
