Effects of microbial-fertilizers on the morphological parameters and biochemical content of Cow pea Vigna unguiculata (L.) Walp. – A biotechnological approach

Abstract

The use of chemical fertilizers and agrochemicals has dangerous effects on both environment and human health. Frequently used chemical fertilizers to increase crop yields and reload soil nutrients have been extinguished by the soil for many years resulting in severe soil microbial communities with serious health and environmental risks. They pollute cultivated land and accumulate in the foodwebs and infect humanity. One of these strategies is based on the use of microbial fertilizers resulting in the field test to solve problems. For this reason in this field experiment was performed with an objective to assess the effects of different microbial fertilizers on preference parameters of cow pea Vigna unguiculata (L.) Walp. The trial was carried out under the following scheme T1 – Control, T2 – Vermicompost (VC), T3 – Rhizobium, T4 – AMF , T5 – Rhizobium + VC , T6 – VC + AMF, T7 – Rhizobium + VC + AMF application. There is an end to the use of single and combination of microbial fertilizers gave the energetic expressed as shoot and root length, number of leaves, total leaf area, fresh and dry weight, as well as the chlorophylls, carotinoid, protein aminoacid and carbohydrates of cow pea seedlings. Increasing among the parameters led to a better positive result of the composition of the microbial fertilizers leading to the efficient action of the morphological and all biochemical mechanisms.
