EFFECT OF INORGANIC LIQUID FERTILIZER AND ORGANIC FERTILIZER IN GROWTH OF MAIZE (ZEA MAYS L.)

ABSTRACT The growth performance of maize (Zea mays), a staple cereal crop of global importance, is greatly influenced by soil fertility and nutrient management practices. This study investigates the comparative effect of inorganic liquid fertilizer and organic fertilizer on the growth of maize. Field and pot experiments were conducted to evaluate parameters such as germination rate, plant height, leaf number, stem girth, and biomass accumulation under varying fertilizer treatments. Inorganic liquid fertilizer treatments provided a rapid supply of essential nutrients that significantly enhanced early vegetative growth and chlorophyll development, leading to faster initial growth responses. Conversely, organic fertilizer application improved soil structure, moisture retention, and microbial activity, contributing to sustained nutrient release and long-term soil fertility. Statistical analysis revealed that while inorganic liquid fertilizer treatments resulted in higher growth indices at early stages, organic fertilizer promoted more balanced growth and improved root development over time. The integrated application of both fertilizer types showed synergistic effects, combining the immediate benefits of inorganic inputs with the residual advantages of organic matter. The findings suggest that balanced use of inorganic and organic fertilizers can optimize maize growth, enhance yield potential, and improve soil health sustainability. This study highlights the importance of adopting integrated nutrient management strategies in maize cultivation for improved productivity and environmental conservation.
