Plant architecture and N fertilizer may limit the performance of intercropped maize (Zea mays L.) and cowpea [Vigna unguiculata (L.) Walpers] cultivars. This paper describes an experiment in which cultivars of maize and cowpea were intercropped and fertilized with varying rates of N. The cowpea c...

Afternoon soil temperature of about 39°C observed at 5 cm depth under sole cassava (Manihot esculenta Crantz) early in the growing season was reduced by respectively 1.0, 1.3, 3.0 and 4.4°C by intercropping with maize (Zea mays L.), maize/okra (Abelmoschus esculentus Moench), maize/ egusi melon (...

Five maize genotypes differing in plant habit and growth period were evaluated at 5 population densities (10, 20, 40, 80 and 160 × 103 plants/ha) under an intercropping system with cassava at 1 × 1 or 1 × 0.67 m spacings in a tropical Alfisol in southern Nigeria. The 2-year study revealed signifi...

Cassava (Manihot esculenta Crantz)/Maize (Zea mays L.) intercropping is so popular in Nigeria that a cassava/maize intercropping package is recommended to small-scale farmers. Farmers insist on including low-growing vegetables like okra (Abelmoschus esculentus Moench) and egusi melon (Citrullus l...

The growth environment of cassava intercropped with maize differs from monocultures of cassava. A trial was conducted to determine the effects of intercropping with maize on micro-environment, growth and yield of cassava. Radiant energy reaching the soil surface and maximum diurnal soil temperatu...

The study was carried out to determine the most appropriate time of introducing rice into cassava with the aim of improving the total productivity of the intercrop. The rice variety Rok 16 was introduced into cassava at four different times—planted at the same time with cassava, and then at 2, 4,...

Changes in earthworm activity, water runoff, soil erosion, soil physical properties and fertility, and crop growth and yield caused by intercropping either maize (Zea mays L.) and cassava (Manihot esculenta Crantz) (MC) or maize, cassava and 'egusi' melon (Citrullus lanatus Thunb.) (MCM) on no-ti...

The cassava variety and population, which when intercropped with rice leads to increased productivity of the system were identified. Two cassava varieties (Cocoa, a local variety; and 80/40, an improved one) were each planted at four populations (6 666, 10 000, 13 333, and 16 666) as sole crops o...
