Abstract

Plant growth-promoting rhizobacteria (PGPRs) stimulate plant growth through their ability, to increasing the root length and growth, by asymbiotic nitrogen fixation, by producing siderophores, solubilization of mineral phosphates and mineralization of other nutrients. Organic waste material of fruits and vegetables was collected and composted in a locally fabricated composting unit. A pot trial was conducted to study the effectiveness of compost and PGPR (Variovorax paradoxus) with recommended rate of PK and with different rates of N fertilizer i.e. 50 %, 75 % and 100 %, on growth and yield of sunflower. Results showed that the integrated use of 75 % N of recommended dose in combination with PGPR inoculation and compost caused a significant increase in grain yield and yield-contributing parameters compared with control. PGPR isolate Variovorax paradoxus in combination with 75 % N of recommended dose and compost gave maximum total achene’s yield 73 % more than control where recommended NPK was applied. Similarly, in case of Plant height, root length, head diameter, head weight, 100 – Achene’s weight and nitrogen content in straw were also increased by PGPR isolate Variovorax paradoxus in combination with 75 % N of the recommended dose and compost up to 11, 109, 27, 26, 17, and 54.0 % respectively over control.
