ABSTRACTDefoliators are common insect pests of soybean and often cause economic losses. Insecticides are the first option that farmers choose to minimize the damage caused by the defoliators, and the result is not only the emergence of resistance to insecticides in the pests but also environmental pollution.

Fertilizer Placement for Sole-Crop Cowpeas in Southern Nigeria
Experimental Agriculture, 1965SummaryThe time and method of placement, and the distance from the plant at which fertilizers should be placed, was studied on sole-crop cowpeas. The development and yield of both early and late season crops were highest where fertilizers were applied at planting. It is suggested that it might be more advantageous to plough the fertilizers under before

The Effects of Sole and Traditional Intercropping of Millet and Cowpea on Soil and Crop Productivity
Experimental Agriculture, 1994SummaryThe after effects of three years' continuous cropping with sole millet, sole cowpea or a traditional millet/cowpea intercrop were compared using five levels of nitrogen fertilizer. The continuous sole cowpea system had reduced the carbon to nitrogen ratio more than the continuous sole millet or the traditional intercrop.

Nitrogen Yield and Land Use Efficiency in Annual Sole Crops and Intercrops
Agronomy Journal, 2006Nitrogen is the most limiting nutrient for crop production on the northern Great Plains of North America. This study was initiated to determine if N yield and land use efficiency for N could be improved by manipulating crop diversity using three annual crops (wheat, Triticum aestivum L.; canola, Brassica napus L.; and field pea, Pisum arvense L ...

Effects of Plant Population on Sole-crop Cassava in Sierra Leone
Experimental Agriculture, 1978SUMMARYEffects of plant population on mean yield and yield components of 2-year sole cassava crops were studied on Njala upland soils of Sierra Leone in two experiments. Increasing plant population of multi-shoot Cocoa cassava over 7000/ha decreased all the parameters studied except top/root weight ratio, which increased.

Weed Productivity and Composition in Sole Crops and Intercrops of Barley and Field Pea
The Journal of Applied Ecology, 1987(1) The hypothesis that intercrops have fewer, smaller weeds than their component sole crops was tested by sowing pure and mixed crops of barley and field pea at commercial densities and at double these densities in two fields near Ithaca, New York, U.S.A.

Animal Production Science, 2011
Dairy farms located in the subtropical cereal belt of Australia rely on winter and summer cereal crops, rather than pastures, for their forage base. Crops are mostly established in tilled seedbeds and the system is vulnerable to fertility decline and water erosion, particularly over summer fallows.

Sesame Sole Crop and Intercrop Response to Fertilizer in Semi‐Arid Niger
Agronomy Journal, 2019Core Ideas Sesame sole crop was highly responsive to fertilizer phosphorus.The profit potential for applied phosphorus was greater for sole crop than intercrop.Sesame did not respond to fertilizer nitrogen and potassium.Sesame‐pearl millet had greater productivity than the sole crops.Manure phosphorus had a high fertilizer phosphorus equivalent. Sesame

Impact of residue addition on soil nitrogen dynamics in intercrop and sole crop agroecosystems
Geoderma, 2017Abstract Soil nitrogen (N) is one of the most important nutrients for plant productivity and microbial activity in terrestrial ecosystems. However, soil N is also readily affected by land management practices, influencing N 2 O emissions. This study assessed N dynamics in soil from different crop systems including a 1:2 (one row of maize and two rows

The comparison of nitrogen use and leaching in sole cropped versus intercropped pea and barley
Nutrient Cycling in Agroecosystems, 2003The effect of sole and intercropping of field pea (Pisum sativum L.) and spring barley (Hordeum vulgare L.) and of crop residue management on crop yield, NO3- leaching and N balance in the cropping system was tested in a 2-year lysimeter experiment on a temperate sandy loam soil.
