Influence of Different Intercropping Patterns and Crop Nutrient Sources on Yields of Soybean (Glycine Max)/Maize (Zea Mays) Intercrops in Karara (Lokoja Lga), Kogi State, Nigeria

Field experiments were conducted during 2017 and 2018 rainy seasons at the Kogi State Agricultural Development farm Karara (Lat. 8.230N, Long. 6.560E Alt. 343.00m) in State, Nigeria to investigates influence of different cropping patterns crop nutrient sources on yields Soybean-Maize intercrops. Treatment consisted two crops (Maize Soybean), fertilizer [Organic source (Poultry Manure) Mineral Fertilizer (Urea)] Intercropping (2:2, 2:3, 2:4, 2:5), sole maize soybean as control. All treatments given factorial combination laid a Randomized Complete Block Design (RCBD) replicated three times. The experiment was carried out for years, averages obtained indicates superiority 2:2 intercropping system over all other systems exemplified by higher Land Equivalent Ratio (LER) 1.13, Aggressivity (A) 0.458, Competitive (CR) 1.63. however showed lowest Relative Crowding Coefficient (RCC) 0.088 which is an indication high productivity. Application mineral form Urea found be more effective than use Poultry manure both years had (RCC), (CR), values maize. Use urea poultry years. Soybean superior competition maize, its productivity dominated total biomass yields. It therefore concluded that with ratio has potential improve not only seed yield but associated biological land efficiently.
