MBONU, O. A. and OSSIA, S. (2006). Growth and Yield of Nsukka Yellow Pepper (Capscicum annum L.) as Affected by Different Organic Ammendments. Nig j. of Agic. Food & Environ. Vol. 3(1&2):72-78.
ABSTRACT:
Dry elephant grass, oil palm bunch and brewers spent grain were incorporated in an ultisol, in south-eastern Nigeria, at the rate of 24 tons/ha. These were planted to Nsukka yellow pepper (Capsicum annum L.), in a randomized complete block design and assessed for their effects on growth and yield of the crop. Plant heights were positively significantly affected by the dry grass treatment. The mean leaf area was in the order 55.54 > 52.32 > 37.00 > 26.20 cm for dry grass, oil palm bunch, control and brewer’s spent grain respectively. The brewer’s spent grain negatively affected both plant height and leaf area. The total yield after 6 weeks of harvest were 4.9, 1.65, 1.63 and 0.5 tons/ha for dry grass, oil palm bunch, control and brewer’s spent grain respectively. About 50% of the pepper fruits for all the treatments were of the large size excluding those of the brewer’s spent grain, which had 80% of the fruits in the small size range. Most of the exchangeable cations were enhanced the dry grass and oil palm bunch treatments. C/N ratios were also reduced by these two treatments.
Key words: Brewers, oil palm bunch, dry elephant grass, ultisol, yellow pepper.
