Effect of Organic Fertilizer (Broiler Litter) and Inorganic Fertilizer (Diammonium Phosphate) on Growth of Common Carp (Cyprinus Carpio Linnaeus, 1758)

Abstract

This work was conducted in the region of Terai, Aurahi gaupalika 2 (Parbaha), Dhanusha distric in the Janakpur Zone, south-east of Nepal to investigate the effect of organic and inorganic fertilizers on the growth performance of Cyprinus carpio communis. The fries were stocked @ of seven fries/m

in 12 cages. Cages were made up of Polyester cloth of one metre length, breadth and height. Treatments were carried out in four different ponds with three replications. Pond A was fertilized with Broiler litter at the rate of 5 g/m /week (@ 2,597 kg/ha/yr). Pond B was kept as control pond i.e. without any treatment. Pond C was treated by broiler litter (@ 5 g/m 2 /weekly) and Diammonium phosphate (5 g/m 2 /biweekly). Pond D was fertilized with Diammonium phosphate (@ 5 g/cage/biweekly). Next day of cage setting it was limed at the rate of 19 g/cage (@ 200 kg/ha). After ten days, fertilization was carried out as treatments required and after ten days fries were stocked in each cage. Length, weight measurement and water quality analysis were carried out before fertilization in each 15 days from stocking to harvesting (90 days). Growth response of Pond A, Pond B, Pond C and Pond D were Mean Initial Weight (0.09 g, 0.09 g, 0.09 g and 0.09 g), Mean Final Weight (3.6 g, 2.4 g, 19 g and 2.53 g), Mean Initial Length (1.7 cm, 1.68 cm, 1.6 cm and 1.63 cm), Mean Final Length (6.43 cm, 6.01 cm, 8.54 cm and 5.7 cm), Specific Growth Rate (1.78 %/day/fish, 1.58 %/day/fish, 2.58 %/day/fish and 1.6 %/day/fish), Percent Weight Gain (3900 %/Fish, 2566 %/Fish, 21011 %/Fish and 2711 %/Fish), Daily Weight Gain (0.039 g/fish/day, 0.025 g/fish/day, 0.21 g/fish/day and 0.027 g/fish/day), Condition factor (1.35 , 1.1, 3.05 and 1.36), r (0.96, 0.99, 0.82 and 0.98), Total Weight (54 g, 36 g, 285 g and 38 g) and production 741.61 kg/ha/year, 494.41 kg/ha/year, 3,914.1 kg/ha/year and 521.19 kg/ha/year. The mean water quality parameters, as temperature, transparency, pH and DO of pond A, Pond B, Pond C and Pond D were (23.3°C, 23.5°C, 23°C and 23.2°C), (33.35 cm, 57.5 cm, 20.5 cm and 25.5 cm), (7.02, 8.35, 6.25 and 7.30) and (4.94 mg/l, 5.20 mg/l, 4.6 mg/l and 5.02 mg/l) respectively. Growth performance of Common Carp is found better in combined use of Organic fertilizer (Broiler litter) with Inorganic fertilizer (DAP) than other treatments, Broiler litter, Diammonium phosphate and control respectively.
