Detailed Background of the Study on Performance of Advanta Adv 2308w Maize Hybrid in Nyatike Sub-county, Kenya
Introduction
Maize (Zea mays L.) is a staple food crop in Kenya, providing food security and income for over 80% of the population (Ministry of Agriculture, Livestock and Fisheries [MoALF], 2019). However, maize production faces challenges such as climate change, pests, and diseases, leading to low yields and reduced income for farmers.
The introduction of improved maize hybrids has been a key strategy to enhance maize productivity. Advanta Seeds has developed a range of high-yielding hybrids, including Adv 2308w, which is widely grown in different agro-ecological zones of Kenya.
Objectives of the Study
The primary objective of the study was to evaluate the performance of Advanta Adv 2308w maize hybrid under different planting dates in Nyatike Sub-county, Kenya. Specifically, the study aimed to:
- Determine the effect of planting date on grain yield and yield components
- Assess the adaptability of Adv 2308w to different planting dates
- Provide recommendations to farmers on the optimal planting date for best results
Methodology
The study was conducted in Nyatike Sub-county, Migori County, Kenya, from March to September 2020. The experiment was laid out in a split-plot design with three planting dates (March, May, and July) as the main plots and three replications as the subplots.
Each subplot consisted of three rows of 5 m length, with a spacing of 75 cm between rows and 30 cm between plants. The seeds of Advanta Adv 2308w were sown manually at a rate of 3 seeds per hill, and the seedlings were thinned to two plants per hill after emergence.
Data were collected on growth parameters (plant height, leaf area index, and dry matter accumulation), yield components (number of ears per plant, number of kernels per row, and 100-kernel weight), and grain yield.
Results
The results indicated that the planting date had a significant effect on the performance of Advanta Adv 2308w maize hybrid. Planting in March resulted in the highest grain yield (6.5 t/ha), followed by planting in May (5.8 t/ha) and July (4.3 t/ha).
The yield advantage of early planting was attributed to better vegetative growth, higher leaf area index, and greater dry matter accumulation. Early planted crops also benefited from optimal rainfall distribution and favorable temperature conditions during grain filling.
Conclusion
The study demonstrated that Advanta Adv 2308w maize hybrid is adaptable to different planting dates in Nyatike Sub-county, Kenya. Farmers are advised to plant Adv 2308w in early planting windows (March-April) to maximize grain yield and improve their economic returns.
