Evaluation of Growth Performances of Some Locally Farmed Maize (Zea mays L.) in Cross River State, Nigeria under Different Concentrations of Silicon.

摘要: OBJECTIVE Growth performances of four maize varieties (91 SUWANI, TZL COMP 4, DT STR Y SYN 2 and IWO C2) were investigated at levels silicon concentration (0, 2500, 5000 7500 mg, with 0 mg as control). METHODOLOGY Viable seeds planted in polythene bags (64 bags) containing soil a randomized complete block design (a 4×4 factorial experiment) replications. Plant height, stem girth, leaf area number evaluated 6, 8 10 weeks after planting. RESULTS There was significant difference (p≤0.05) for all growth parameters across varieties. Highest mean plant height (144.58 cm) leaves (12.23) recorded varieties, while girth biomass highest COMP4 (3.42 cm, 38.44 dry weight g-1). CONCLUSION Based on these results, is recommended nutrient supplement to enhance production.
