The demands placed on global agricultural production arising out of population and income has grown almost tripled. In order to meet the increasing demand, it is mandatory to elevate the production by avoiding the usage of chemical fertilizers that makes the soil barren, unfertile and pollutes the environment as well as harmful to the consumers, where the biofertilizers came in to play. Microalgae can be played a pivotal role in building and maintaining soil fertility, subsequently increasing the growth as well as yield of several agricultural crops. But the reports on production of black gram were found to be scanty and thus this study focuses on its possible role. Algal extracts of varying concentrations were used as foliar sprays treatment and growth parameters; number of root nodules, yield attributes and quality parameters were measured. The implication of green algae as biofertilizer not only increases the yield characters but also improvises the soil physico-chemical properties. In addition, there was a subsequent increase in number of root modules, pigment compositions and yield attributes. Thus, the microalgae benefit the consumers by increasing the proximate composition and a mineral constituent is an added advantage. The results clearly depicted that the treatment of Chlorella vulgaris resulted in the identification of economically feasible, ecofriendly foliar spray treatment for the augmenting the maximum yield in black grams.

黑小豆Vigna mungo（L.）的小球藻可促进生长和产量，并具有优异的种子品质

由人口和收入引起的对全球农业生产的需求几乎增长了两倍。为了满足不断增长的需求，必须通过避免使用化学肥料来提高产量，因为化肥会使土壤变得贫瘠，贫瘠，污染环境以及对使用生物肥料的消费者有害。微藻可以在建立和维持土壤肥力，随后增加几种农作物的生长以及单产方面发挥关键作用。但是发现关于黑克的报告很少，因此本研究着重于其可能的作用。不同浓度的藻类提取物被用作叶面喷雾剂的处理和生长参数。测量根瘤数，产量属性和质量参数。绿藻作为生物肥料的应用不仅增加了产量，而且改善了土壤的理化特性。另外，随后的根模块，颜料组成和产量属性的数量也增加了。因此，微藻类通过增加附近的组成而使消费者受益，而矿物质成分是附加的优点。结果清楚地表明，小球藻导致鉴定出经济上可行的，生态友好的叶面喷雾处理，以增加黑克的最大产量。
