The purpose of the experiment was to examine the effect of different food sources on the growth and reproduction performances of an epigeic earthworm .
The experiment was carried out in 18 cylindrical plastic containers for 10 weeks. The study was designed with six treatments, each having three replicates. In control treatment (T), cow dung was used as the only food source for the earthworm. In another five treatments, water hyacinth (T), chopped banana plant trunk (T), vegetable scrap (T), paddy straw (T), and sugarcane bagasse (T6) were used as food sources with cow dung as bedding material.
The maximum weight gain of earthworm was 3,294.7 ± 4.5 mg for the food staff of vegetable scrap (T). Earthworm fed with chopped banana plant trunk (T) showed a very similar weight gain of 3,243.7 ± 3.8 mg. On the contrary, the minimum weight gain was 1,799.7 ± 3.5 mg for the food staff of paddy straw (T). The maximum cocoon number of 137.33 ± 6.46 mg was observed in T, whereas a minimum number of 36.67 ± 4.16 mg in T. The highest number of hatchlings (12.33 ± 0.88 mg) was recorded in treatment T, whereas the least number of hatchling (5.00 ± 0.58 mg) was observed in T.
It was concluded that, among the six different food sources, chopped banana plant trunk was preferable food source to the earthworm for growth and reproduction.
本实验旨在研究不同食物来源对一种表栖蚯蚓生长和繁殖性能的影响。
实验在18个圆柱形塑料容器中进行，为期10周。该研究设计了六种处理方式，每种处理方式有三个重复。在对照处理（T）中，牛粪被用作蚯蚓的唯一食物来源。在另外五种处理中，水葫芦（T）、切碎的香蕉植株茎干（T）、蔬菜残渣（T）、稻草（T）和甘蔗渣（T6）被用作食物来源，牛粪作为垫料。
蔬菜残渣（T）作为食物时蚯蚓的最大体重增加量为3294.7±4.5毫克。以切碎的香蕉植株茎干（T）为食的蚯蚓体重增加量与之非常相似，为3243.7±3.8毫克。相反，稻草（T）作为食物时蚯蚓的最小体重增加量为1799.7±3.5毫克。在T处理中观察到的茧的最大数量为137.33±6.46个，而在T处理中最小数量为36.67±4.16个。在T处理中记录到的幼蚓最高数量为（12.33±0.88个），而在T处理中观察到的幼蚓数量最少（5.00±0.58个）。
得出的结论是，在六种不同的食物来源中，切碎的香蕉植株茎干是蚯蚓生长和繁殖的较优食物来源。
