Abstract

An experiment was conducted to study the effect of two sources water (Fish culture water (Fcw) and Nile freshwater (Nfw)) and nitrogen levels fertilizer on biodiversity of Spider, other arthropods, the yield and protein of cowpea. Spiders were determined throughout the period of study using the Shannon-Wiener and Simpson Indices of diversity. A total of 394 individuals (228 in Fcw and 166 Nfw) represented by 10 families of 19 identified genera, of higher diversity index in Fcw system. According to Simpson, it was found that Fcw system included the highest number of dominant species. Family Lycosidae recorded the highest number of spiders where 170 individuals with two egg sac and 123 individuals with two egg sac of Fcw system and Nile freshwater system respectively. Sorensen Quotient of Similarity between Fcw system and Nfw system are nearly approximate, as they recorded 64 % of similarity by 81.25%. Other Arthropods were represented by 23 species belonging to 16 identified families, 7 unidentified families, and 12 orders. A total of 2832 individuals in Fcw system and 2169 individuals in Nfw system were counted from 9 observations on cowpea from seedling to maturity by using pitfall trap. A total of 471 individuals in Fcw system and 592 individuals in Nfw system by using Leaves. Statistical analysis for spider, soil fauna, pests on leaves, yield and protein were discussed
