Influence of Nitrogen, Phosphorus and Cow Dung Manure on the Yield and Yield Components of Two Okra Varieties in Anyigba, Kogi State

Musa U.T


A field experiment was conducted at Kogi State University Research and student demonstration farm Anyigba during the 2015 raining season to determine the influence of Nitrogen, Phosphorus and Cow dung manure on the yield and yield components of okra varieties. The treatment consisted of two okra varieties (Velvet 35 and Lima F1), four levels each of Nitrogen (0, 55kilogram/hectare, 110 kilogram/hectare, 220 kilogram/hectare), Phosphorus (0, 125 kilogram/hectare, 250 kilogram/hectare and 500 kilogram/hectare) and Cow dung (0, 6.25tonnes/hectare, 12.5tonnes/hectare, and 25tonnes/hectare), which were replicated three times and laid out in randomized complete block design (RCBD). Urea and Single Super Phosphate were used as the source of Nitrogen and Phosphorus respectively.  Data were obtained for growth and yield parameters, three plants were randomly selected and tagged per plot for data collection. Results shows that stem girth, number of leaves, branches, fruits, leaf area, fruit length, and fruit yield etc. were significantly influenced for the okra varieties as Lima F1 out-yielded velvet 35. There was a significant interaction of fertilizer and variety on yield characters such as fruit length and yield etc.

Keywords: Cow dung, growth, interaction, nitrogen, okra seeds, phosphorus, soil analysis, yield.
