Impact of leaf damage by defoliators on yield of soybean as a sole crop and as a main crop in intercropping systems

International Journal of Pest Management, 2017
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, 1965
SummaryThe 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, 1994
SummaryThe 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, 2006
Nitrogen 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 ...

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.

Effects of Plant Population on Sole-crop Cassava in Sierra Leone

Experimental Agriculture, 1978
SUMMARYEffects 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.

Nitrogen fertilizer effects on yield and nitrogen uptake of sorghum and soybean, grown in sole cropping and intercropping systems

Field Crops Research, 1985
With the dissemination of improved cereal genotypes, low soil N fertility has become a significant constraint in many cereal production systems, including that of intercropping. An experiment was conducted in S.E.

Sesame Sole Crop and Intercrop Response to Fertilizer in Semi‐Arid Niger

Agronomy Journal, 2019
Core 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

The role of tillage, fertiliser and forage species in sustaining dairying based on crops in southern Queensland 2. Double-crop and summer sole-crop systems

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.

Changes in Soil Physical Properties After Intercropping as Against Sole Cropping

Journal of Agronomy and Crop Science, 1989
AbstractTwo field trials under irrigated conditions were conducted in red sandy loam soils of Palathurai series (Typic Haplustalf) at Coimbatore to evaluate the changes in physical properties when intercropping was introduced to a pure crop system. The results of the first crop indicated that intercropping of sorghum (CSH 5)‐lab lab (CO 9) system was ...
