Productivity of Millet / Cowpea Intercrop as Affected by Cowpea Genotype and Row Arrangement
Six cowpea genotypes (Danila, IT96D-772, IT90K-277-2, IT95K-1091-3, IT96D-740, IT96D-757) were intercropped with a local millet cultivar using four row arrangements (1:1, 1:2, 2:2 and 2:4 millet to cowpea rows) in a field experiment conducted at Minjibir near Kano in the Sudan savanna ecological zone of Nigeria during the 1999 and 2000 wet seasons. Cowpea genotypes and row arrangement had no ef...
متن کاملBiological control of Striga hermonthica by Cubitermes termite mound powder amendment in sorghum culture
Striga hermonthica (Del.) Benth is an obligate root hemi-parasite of several cereals. Its effect on cereal crops is the main constraint for food production in sub-Saharan Africa. Various control methods have been already proposed, but the infestation by these parasitic plants persists. An appropriated method for Striga management adapted for the African farmer is very much needed. In this study...
متن کاملPhosphorus Requirements of Soybean and Cowpea as Affected by Mode of N Nutrition
A field experiment was conducted on a tropical soil (Humoxic Tropohumult) with a high P sorption capacity to compare the critical external and internal P requirements of soybean (Glycine max (L) Merr.) and cowpea (Vigna unguiculata () Walp.) as affected by the predominant mode of N nutrition during crop growth. The experiment had a split-plot design with two N-level subplots established within ...
