I. I. Dominic, N. M. Akpan Green pepper, quality, shelf life, manure rate, phytochemical 58-65 9 (3) July 2025 This experiment was conducted to study the response of green pepper fruits to different manure doses (Control (Zero application), 5t/ha of poultry manure (PM), 10t/ha of PM, 300kg/ha of NPK 15:15:15, 5t/ha of PM + 200kg/ha of NPK 15:15:15, 10t/ha of PM + 100kg/ha of NPK 15:15:15). The results showed that there was a significant changes (p ≤ 0.05) among manure doses on green life as extended green life of 14.0 days was obtained in control plot and the least in 5t/ha of PM and 300 kg/ha of NPK (9.0 days, each). The varying manure doses have been seen positive effect on fruit shelf life. Pepper fruits with longest shelf life of 28.7 and 28.3 days was obtained in 10 t/ha of PM + 100 kg/ha of NPK, and control plot, respectively and the least in 5 t/ha of PM (18.70 days). Varying level of manure application also effected the vitamins, phytochemical and mineral contents of green pepper fruits. It revealed that fruits did not differ significantly, but 10 t/ha of PM + 100 kg/ha of NPK had the highest Vitamin A content while the highest Vitamin B3 and C content was obtained in 5 t/ha of PM + 200 kg/ha of NPK. For phytochemicals, it was observed that 10 t/ha of PM + 100 kg/ha of NPK had the highest alkaloid and flavonoid content while 10 t/ha of PM + 100 kg/ha of NPK had the highest iron, potassium and zinc content.
