EFFECT OF DIFFERENT SU BSTRATES AND FETERLIZER APPLICATION RATES ON MICRO MINERAL CONTENTS OF Sorghum bicolor IN A SOILLESS FARMING SYSTEM
(2024-10-24) ADEJARE, OMOLOLA OLAITAN
ABSTRACT This research was conducted to evaluate the effect of different substrates and fertilizer application rates on the micro mineral contents of Sorghum bicolor in a soilless farming system. The study was a 3 × 3 factorial design, i.e. nine treatment combinations with four replicates to give a total of 36 bags. The 3 × 3 stands for 3 rates of fertilizer application (0, 120 and 240 kg/ha), the second factor was 3 substrate level (coco peat, rice husk, grow mix). The micro mineral contents ( Mn, Zn, Fe and Mg) in sorghum bicolor was determined and Data collected were analyzed using a two-way analysis of variance (ANOVA) and treatment means were separated using Tukey HSD test of R statistics. Micro mineral content of S. bicolor differs significantly (p<0.05) as influenced by different substrates except for copper (Cu) content. The values which was recorded for manganese (Mn) ranged from 10.17mg/kg for plants grown in rice husk (RH) filled bags to 6.07mg/kg for plants harvested from grow mix (GM) filled bags. Interaction effect between different substrates and fertilizer application rates on micro mineral content of S. bicolor significantly influenced (p<0.05) all micro mineral contents of S. bicolor except Iron (Fe). Plants sown in Coco peats (CP) filled bags, fertilized with 120kg/ha of NPK recorded the highest (11.58mg/kg) value for manganese (Mn), while unfertilized plants grown in Rice husk (RH) bags recorded the least value (6.44mg/kg). These shows the importance of selecting appropriate substrates and optimizing fertilizer rates to ensure balanced micronutrient availability in soilless farming systems.
