Supplementation of P with rhizobial inoculants to improve growth of Peanut plants
Rabia Badar, Zaibun Nisa, Saima Ibrahim
Biological nitrogen fixation represents the major source of N input in agricultural soils and rhizobia chemically convert the nitrogen from the air to make it available for the plant.The N fixation process is influenced by many factors and P is one of them. Due to the important role played by P in the physiological processes of plants, application of P to soil deficient in this nutrient leads to increase plant growth and yield. This research was carried out to investigate the effects of biological and chemical fertilizers on some physiological characters of peanut plants. Five different rhizobial inoculants (approximately 1.9 x 108 cfu) alone and in combination with DAP (as phosphate fertilizer @ 60kg/ha) were used as treatments. After 30 days of germination all the treatments showed significant effects on physical parameters of peanut plants, more significant results observed when plants treated with rhizobial inoculations with combination of DAP. Due to the imperative role played by P in the physiological processes of plants, application of P with rhizobial inoculants are beneficial for leguminous plants growth.
