Maize (Zea mays) is one of the most important cereal crops in the world, providing food, feed, and industrial raw materials. In semi-arid areas like Nyatike, Kenya, maize production is often limited by low soil fertility and erratic rainfall patterns. In order to improve maize yields in these areas, farmers often rely on the application of fertilizers, particularly nitrogen (N), phosphorus (P), and potassium (K).
The physio agronomic response of maize hybrids to different rates of NPK fertilizer application has been a subject of interest for researchers and agronomists. Understanding how maize hybrids respond to different fertilizer rates can help farmers optimize their fertilizer use and improve crop yields.
One study that investigated the physio agronomic response of maize hybrids (specifically DK 777) to different rates of NPK fertilizer application in semi-arid areas is the research conducted by Ouma et al. (2017). In their study, the researchers evaluated the effects of different NPK fertilizer rates on the growth, yield, and nutrient uptake of maize hybrids in Nyatike, Kenya. They found that the application of NPK fertilizer significantly increased maize yield and nutrient uptake, with the highest yields recorded at the highest fertilizer rates.
Another study by Nyamai et al. (2019) also looked at the physio agronomic response of maize hybrids to different rates of NPK fertilizer application in semi-arid areas. The researchers found that the application of NPK fertilizer improved maize growth and yield, with the highest yields recorded at moderate fertilizer rates.
Overall, these studies highlight the importance of optimizing NPK fertilizer application rates for maize production in semi-arid areas like Nyatike. By understanding how maize hybrids respond to different fertilizer rates, farmers can improve their fertilizer use efficiency and maximize crop yields.

Background of the Study on Physio-Agronomic Response of Maize Hybrids (DK 777) to Different Rates of NPK Fertiliser Application Rates in Semi-Arid Area of Nyatike
Maize Production in Kenya
Maize is a staple food crop in Kenya and a key contributor to the country's food security. However, maize production is often constrained by low soil fertility, particularly in semi-arid areas.
Nyatike Sub-County
Nyatike Sub-County in Migori County is located in the semi-arid region of Western Kenya. The soils in this area are characterized by low nutrient content and water-holding capacity.
Maize Hybrid DK 777
DK 777 is a drought-tolerant maize hybrid that has been widely adopted in semi-arid regions of Kenya. It has been reported to have high yield potential under limited water availability.
NPK Fertilizers
Nitrogen (N), phosphorus (P), and potassium (K) are essential plant nutrients that play a crucial role in maize growth and development. Adequate application of these nutrients is critical to optimize maize yield.
Need for the Study
Despite the importance of maize production in Nyatike and the availability of improved hybrids like DK 777, there is limited information on the physio-agronomic response of this hybrid to different rates of NPK fertilizer application. This study aimed to address this knowledge gap and provide recommendations for optimizing maize production in the semi-arid area of Nyatike.
