Impact of microfertile® plant Biostimulant on Maize Growth and Yield under Different Climatic Conditions in Kenya

Abstract

The objective of this study was to assess the effects of microfertile® plant biostimulant applications on maize (Zea mays L.) growth and yield under varying agro-ecological conditions in Kenya. Five treatments were applied, including three application rates of microfertile® plant (3, 4 and 5 L/acre), a commercially available biostimulant as a reference, and an untreated control. The results obtained demonstrated that microfertile® plant significantly enhanced maize performance across key growth parameters, including plant height, ear length, grains per cob, and overall grain yield. The application of the high-rate microfertile® plant treatment (5 L/acre) resulted in the cultivation of the most elevated plants. In a similar manner, the mean ear length exhibited a marked increase in the 5 L/acre treatment, attaining a maximum of 13.0 cm, which signifies an augmentation of 43.2% in comparison with the control group (9.08 cm). With regard to reproductive parameters, the 4 and 5 L/acre microfertile® plant treatments achieved the highest grain counts per cob. Grain yield was found to be significantly influenced by the treatments applied. The highest yield was recorded in the 5 L/acre microfertile® plant. It is worthy of note that the lowest microfertile® plant rate (3 L/acre) exhibited superior performance in comparison to the reference biostimulant, thereby reinforcing the efficacy of microfertile® plant in augmenting maize yield. The 4 and 5 L/acre treatments resulted in a reduction of approximately 2-3 days in the time to reach maturity, in comparison with the reference biostimulant. This is a favorable adaptation for the management of planting schedules and the optimization of land use in the context of changing climate conditions. This study demonstrates the potential of microfertile® plant to function as a sustainable alternative to traditional inputs, thereby contributing to enhanced maize productivity and improved adaptability across diverse environments. The findings support the use of microfertile® plant as a climate-smart solution that aligns with the goals of sustainable agriculture.
