Abstract

Mixed leaf pruning can be used to ameliorate nutrient losses for increased crop yield. This study was undertaken to investigate leaf pruning quality on maize agronomic performance in a cut and carry agroforestry system to optimize N-use efficiency. The experiment consisted treatment of 100g Gliricidia; 50g Gliricidia + 50g Acacia; 100g Acacia; 60g Gliricidia + 40g Acacia; 40g Gliricidia+ 60g Acacia and control laid out in Completely Randomized Design  with three replicates. Two Oba Super 2 maize seeds per hole were sown during raining season. One week after sowing, the seedlings were thinned to one per stand and treatment was applied 3WAS. Treatment effects measurement on maize growth started two weeks after mulch application and was repeated at 4, 6 and 8 weeks.  Matured and dried maize cobs were harvested; the grain yield was evaluated. Significantly higher grain yield was observed between control and plots with applied mulches; no significant difference in yield from the varied quality mulched plots. At 8WAS and 10WAS, plots treated with 40g Gliricidia + 60g Acacia, 100g Acacia, 60g Gliricidia + 40g Acacia, 50g Gliricidia + 50g Acacia, 100g Gliricidia and control were significantly  different in height. Maize plants mulched with 40g Gliricidia + 60g Acacia, control and 100g Acacia had significantly  bigger stem diameters while others were not significant at 6WAS. Plant height, stem diameter, number of leaves and below ground biomass showed that 40g Gliricidia + 60g Acacia had significantly best effects.
