CORRELATION STUDIES IN GROWTH, YIELD COMPONENTS AND YIELD IN MAIZE (Zea mays) IN ANYIGBA, KOGI .....

The photosynthetic machinery in plants' leaves is responsible for the production of carbohydrates using the sun's energy, carbon dioxide (CO2), and water. Leaf area (LA) appears to be the most relevant leaf characteristic for forecasting grain yield, particularly in maize. Leaf area (LA) is crucial in plant growth analysis because leaf growth influences light interception, which impacts crop development and yield in cereals. An experiment was carried out at Kogi State University in Anyigba, Kogi State, Nigeria, on correlation studies in maize (Zea mays) growth, yield components, and yield to determine the effects of LA on maize growth, yield components, and yield. The quantity of Seeds/Cob reflects the influence of leaf area on grain yield. The strongest correlation value (0.678) was discovered in this study between LA and Seeds/Cob. Other factors, like as plant height and leaf number, had a favourable impact on the final grain production. All of these characters had a strong and positive relationship with Leaf Area. Using the regression equation, it was discovered that Seeds/Cob had the highest influence on Leaf Area, implying that more Seeds/Cob resulted in higher photosynthete and starch accumulation, resulting in enhanced maize production. In conclusion, the correlations between Leaf Area and some components like as height, leaf number, and Seeds/Cob should be taken into account while boosting grain yield and predicting Leaf Area.
