Microalgae-based biofertilizers have been proven to be very successful and an alternate source for agricultural sectors in reducing the usage of harmful chemical fertilizers. Focusing on this, liquid biofertilizer extracts of Chlorella vulgaris and Spirulina platensis are used to improve the growth of green gram Vigna radiata (L.). The microalgal extracts of Chlorella vulgaris and Spirulina platensis showed maximum chemical composition and elemental contents. Growth parameters of shoot, root length, and weight of green gram (Vigna radiata) at flowering stage were found to be at a higher level with treatments I and II. Similarly, maximum number of fresh weights of root nodules, plant heights, plant branches, plant leaves, and leaf area index were recorded as 100% with treatment I of Chlorella vulgaris and treatment II of Spirulina platensis in treated plants. The leaf chemical composition such as N, P, and K, total carbohydrates, Indole, and phenol evidenced with good results in plants treated with Chlorella vulgaris and Spirulina platensis. The soil characterisstics such as pH, EC (ds/m), Ca++, Na+, Mg++, K+, CO3, Cl, HCO3, and So4 and physical characteristics of green gram including water absorption index, water solubility index, water absorption, and oil absorption were observed in superior level in microalgae-treated plants. The proximate composition and mineral composition of green gram seed flour were also recorded to be higher with Chlorella vulgaris and Spirulina platensis treatments. The antinutritional factors and phytohaemagglutinating activities of green gram were also found to be higher in microalgal-treated plants. Thus, the implications of Chlorella vulgaris as well as Spirulina platensis were proven to be pros of liquid biofertilizers in the production of green gram.

微藻液体生物肥料及其对绿豆(Vigna radiata L)实验性栽培的生物刺激作用

事实证明,基于微藻的生物肥料非常成功,是农业部门减少有害化学肥料用量的替代来源。着眼于此,小球藻螺旋藻的液体生物肥料提取物被用于改善绿豆Vi豆的生长。小球藻螺旋藻的微藻提取物显示出最大的化学组成和元素含量。绿芽(Vigna radiata)的枝条生长参数,根长和重量发现I和II处理在开花阶段的水平较高)。同样,在处理过的植物中,用普通小球藻处理I和螺旋藻处理II处理的根瘤最大鲜重数,植物高度,植物分支,植物叶片和叶面积指数记录为100%。在用小球藻螺旋藻处理过的植物中,叶片化学成分(例如N,P和K,总碳水化合物,吲哚和苯酚)表现出良好的效果土壤特性,例如pH,EC(ds / m),Ca ++,Na +,Mg ++,K +,CO - 3,Cl-,HCO - 3和So 4以及在微藻处理过的植物中均观察到绿豆的物理特性,包括吸水指数,水溶性指数,吸水率和吸油率。近端组合物和绿色克种子粉的矿物组成,同时记录与要高小球藻螺旋藻治疗。在微藻处理过的植物中,绿豆的抗营养因子和植物血凝活性也更高。因此,小球藻螺旋藻的影响 事实证明,绿克生产中液态生物肥料是有利的。
