Maize is a staple crop in Kenya, particularly in semi-arid areas like Nyatike sub county. In order to maximize maize production in these challenging environments, it is important to understand how different maize hybrids respond to varying rates of NPK fertiliser. This study aims to investigate the physio-agronomic response of maize hybrids to different rates of NPK fertiliser in Nyatike sub county, Kenya.
Several studies have been conducted on the effects of NPK fertiliser on maize production in various regions. For example, a study by Mafongoya et al. (2006) found that NPK fertiliser application significantly increased maize yield in Zimbabwe. Similarly, a study by Girma et al. (2014) in Ethiopia showed that NPK fertiliser application improved maize growth and yield.
In the context of semi-arid areas like Nyatike sub county, understanding the physio-agronomic response of maize hybrids to NPK fertiliser is crucial for sustainable maize production. By identifying the optimal rates of NPK fertiliser for different maize hybrids, farmers in these areas can improve their crop yields and livelihoods.
Overall, this study will contribute to the existing body of knowledge on maize production in semi-arid areas and provide valuable insights for farmers and policymakers in Nyatike sub county, Kenya.

The study was conducted in semi-arid areas of Nyatike sub-county, Kenya, with the aim of investigating the physio-agronomic response of maize hybrids to different rates of NPK fertilizer. The specific objectives were to:
(i) Determine the effect of different rates of NPK fertilizer on the growth and yield of maize hybrids;
(ii) Evaluate the economic feasibility of using different rates of NPK fertilizer on maize production;
(iii) Identify the most suitable maize hybrid for the semi-arid areas of Nyatike sub-county.
The study was conducted in a randomized complete block design with three replications. Four maize hybrids (H1, H2, H3 and H4) and four rates of NPK fertilizer (0, 50, 100 and 150 kg/ha) were used. The data were collected on plant height, leaf area, dry matter yield, grain yield, and economic parameters. The results showed that the application of NPK fertilizer significantly increased the growth and yield of maize hybrids. The highest grain yield was obtained at the rate of 100 kg/ha of NPK fertilizer. The economic analysis showed that the use of NPK fertilizer was economically feasible at the rate of 100 kg/ha. The most suitable maize hybrid for the semi-arid areas of Nyatike sub-county was H2, which gave the highest grain yield at the rate of 100 kg/ha of NPK fertilizer.
