Effects of Groundnut Shell Incorporation Rates on the Growth and Yield of Maize (Zea mays L.) in Mubi, Adamawa State, Nigeria
Biotechnology Journal International,
Purpose: The aim of the study was to assess the effects of groundnut shell incorporation rates on the growth and yield of maize.
Research methods: The study was carried out at the students’ demonstration farm of the Federal Polytechnic, Mubi, Adamawa State, in 2018. Seeds were sown on a prepared land treated with four (4) doses of groundnut shells (0, 25, 50 and 75 tons/ha) arranged in a randomized complete block design (RCBD), replicated 4 times. Each plot was marked out at 2.0 m length × 2.0 m width with 0.5 m gap between the replicated plots and blocks. Maize growth parameters were determined at 2, 4, 6 and 8 weeks after sowing and maize yield parameters were determined at 10 and 12 weeks after sowing (WAS).
Findings: The groundnut shell application rates increased maize growth parameters such as, plant height, number of leaves per plant, leave area index, and stem girth, number of cobs per plant and cobs weight. The results revealed that plant height, number of leaves, leaf area index and stem girth were significantly (P≤ 0.05) influenced by the treatments, except for the control treatment at 2- WAS. The higher application rates (50 and 75 t/ha) of groundnut shell significantly (P≤ 0.05) influenced the plant growth components better than the 25 and 0 t/ha treatment rates.
Research limitations: There were no limitations to report.
Originality/Value: The results suggests that groundnut shell incorporation rate at 50 t/ha could be recommended as the most appropriate and profitable for high performance of maize plants in Mubi. The results generally suggest that maize plants may tolerate even higher rates of groundnut shell incorporation beyond the rates used in the study.
