POULTRY MANURE RATES INFLUENCED NUTRITIONAL COMPOSITION OF CARROT (Daucus carota L.) IN UMUDIKE RAINFOREST ZONE.

Abstract

A laboratory experiment was carried out to determine proximate, vitamins and mineral concentration of carrot grown under different rates of poultry manure in umudike southeastern Nigeria. Samples were sourced from field research comprising of four rates (control, 10, 20 and 30 t/ha) of poultry manure in the department of crop and horticultural sciences, umudike during October 2024 cropping season. The determination was done in triplicates using standard methods (AOAC, 2003) in a completely randomized design format. The result showed that all the proximate parameters determined were significantly (P<0.05) influenced with the exception of carbohydrate. Control plot had the higher Ash content of 1.28 % and Crude fat of 0.35 % contents compared to others. However, -1 the plot that received 30 tha of poultry manure had the higher Crude fibre of 2.71 % and Dry matter -1 content of 21.71 g than other treatments. The 10 tha poultry manure gave the higher Crude protein content than other soil amendments. The plot that received 10t/ha of poultry manure gave the higher-1 mean value 0.25 (mg/100 g) of vitamin B1 while 20 tha of poultry manure gave the least 0.17 (mg/100g). The control treatment gave the higher mean value 0.32 (mg/100g), 19.52 (mg/100g) and 0.95 (mg/100g) of vitamin B2, vitamin C and vitamin E, respectively, while the least came from-1 application of 30 tha of poultry manure. The result of the minerals assayed differed significantly (P<0.05). The control plot had higher concentration of Calcium of 32.48 (mg/100g), Sodium 45.30 (mg/100g) and Magnesium 19.74 (mg/100g), however, potassium content was higher in the plot that-1 received 30t/ha of poultry manure.30 tha of poultry manure.
