Humans have been using natural resources for their daily life support. The population boom around the world has created a need to develop a new technique for increased crop production. Chemical fertilizers used in modern agriculture lead to pollution, besides increase in farming costs. To solve this problem, the present study deals with a natural halotolerant Enterobacter hormaechei which can fix N and solubilize desired macronutrients P and K. Enterobacter hormaechei was able to solubilize K-feldspar into potassium (97.5 ± 1.76 mg/L), tri-calcium phosphate into phosphate (99.7 ± 02 µg/mL) and it also produced IAA (47.87 ± 0.85 mg/L). Experiments, including morphological and chemical analysis, have provided a new growth pattern in Lycopersicum esculentum. Tomato seeds (Lycopersicum esculentum) treated with Enterobacter hormaechei enhanced biomass and an increase in shoot length when compared to control. It enhanced not only plant growth but modified the root architecture leading to improved crop productivity.
人类一直在利用自然资源来维持日常生活。全球人口的激增使得开发一种提高作物产量的新技术成为必要。现代农业中使用的化肥除了增加种植成本外，还会导致污染。为了解决这个问题，本研究涉及一种天然耐盐的霍氏肠杆菌，它可以固氮并溶解所需的大量营养素磷和钾。霍氏肠杆菌能够将钾长石溶解为钾（97.5±1.76毫克/升），将磷酸三钙溶解为磷酸盐（99.7±0.02微克/毫升），并且它还产生吲哚-3-乙酸（47.87±0.85毫克/升）。包括形态学和化学分析在内的实验为番茄提供了一种新的生长模式。与对照相比，用霍氏肠杆菌处理的番茄种子（番茄）提高了生物量并增加了茎长。它不仅促进了植物生长，还改变了根系结构，从而提高了作物产量。
