Comparative Analysis of Organic, Inorganic, and Plant Growth Promoting Bacteria Fertilizers on Pisum sativum Growth

Abstract

The use of fertilizers has become a ubiquitous practice in agriculture, with farmers and agriculturists relying on them to Nurture soil fertility and optimize plant growth conditions. Fertilizers can be broadly grouped into three categories: organic fertilizers, inorganic fertilizers, and plant growth promoting bacteria. Organic fertilizers, such as livestock manure, agricultural waste and municipal sludge, offer a natural and sustainable alternative to synthetic fertilizers. Inorganic fertilizers, on the other hand, are based on chemical substances like nitrogen, phosphorus, calcium, and potassium. Plant growth promoting bacteria, including Rhizobium, Azospirilium, Azobacter, and Cyanobacteria, have also gained popularity for their ability to enhance plant growth.

This study aimed to conduct an analysis of these three fertilizer types to determine their effectiveness in promoting pea plant growth. To achieve this, pea plants were grown using each of the three fertilizers, as well as a control group without any fertilizer. The plants were then subjected to various tests, including soil pH, water holding capacity, fresh weight, dry weight, root length, and shoot length.

The results revealed that plants grown with organic fertilizers exhibited the most efficient growth patterns, followed by the control group, inorganic fertilizers, and plant growth promoting bacteria. Notably, the plant growth promoting bacteria showed the least growth among the four groups. These findings suggest that organic fertilizers may be a more effective and sustainable option for promoting plant growth, and highlight the need for further research into the optimal use of different fertilizer types.
