Abstract
A field experiment was conducted at the Zambia Agriculture Research Institute (ZARI), Kabwe Research Station during the 2024/2025 cropping season to evaluate the efficacy of two microbial-based biofertilizers: SRI GOLD BIO NPK (granulated) and PICK UP GA (soluble powder), both produced by Contec Global UK.
Nine fertility treatments were tested, including sole applications, combinations, and integration with conventional fertilizers, using maize variety ZMS 631.
Results demonstrated that SRI GOLD BIO NPK significantly enhanced maize yield as a sole application (2859 kg/ha) compared to the control (1833 kg/ha). PICK UP GA applied alone showed limited improvement (2137 kg/ha). The combination of both products yielded 2583 kg/ha, a 41% increase over the control but statistically insignificant. Integration with conventional urea (200 kg/ha) markedly improved yields (5158 and 4513 kg/ha for SRI GOLD BIO NPK and PICK UP GA, respectively), although still below the full conventional fertilization regime (6452 kg/ha). When half-rates of conventional fertilizer were combined with biofertilizers, yields remained considerably higher than the control (4183 and 3205 kg/ha). The study highlights that integrating microbial biofertilizers with inorganic inputs can reduce chemical fertilizer dependence while sustaining yields in maize production systems.
