Abstract

The study explores the application of the root endophytes Piriformospora indica and the arbuscular mycorrhizal fungus (AMF) Glomus mosseae as biofertilizers to enhance cassava growth and productivity. The successful colonization of cassava roots by P. indica and AMF was detected, confirming their effective association with the host plant. Root growth parameters were found to be significantly increased in the cassava plants colonized by P. indica when compared to uninoculated control plants. In a field study, the combination of 75 % of the recommended NPK dose along with P. indica was identified as the most effective treatment for enhancing growth and yield attributes. In contrast, the combination of 75 % of the NPK dose along with AMF showed the most significant improvement in total dry matter content and tuber quality parameters. The results showed that the nutrient dose can be reduced to a level of 75 % of the recommended dose, without compromising the growth and yield, if the chemical fertilizers are applied along with the bio-inoculants, either P. indica or AMF. The same treatments also resulted in higher total nitrogen uptake, while the combination of 100 % NPK and AMF resulted in better phosphorus and potassium uptake by the cassava plants.  This is the first report demonstrating root colonization, growth promotion and improved nutrient acquisition in cassava following inoculation with the beneficial root endophyte P. indica.
