A field experiment was carried out to investigate the effects of variety and spatial arrangement on pest incidence, damage and subsequent yield of cowpea in a cowpea/maize intercrop. Two varieties of cowpea (Tvu 13076 and Ife brown) and two spatial arrangements (2:3 maize/ cowpea & 1:1maize/ cowpea intercrops) were investigated. There was Lower population density of Maruca vitrata among the 1:1...

in order to evaluate millet (panicum miliaceum l.) and cowpea (vigna unguiculata l.) intercropping, an experiment was conducted during 2008-2009 at agriculture research center of zabol university, iran. the experiment was as randomized complete block design with three replications. treatment s consisted of sole crop of millet, sole crop of cowpea, 25% millet + 100% cowpea, 50% millet + 50% cowp...

ABSTRACT- Declining land productivity associated with decreasing soil organic carbon and nutrients is a significant issue in monoculture production. The field experiment with different rates of fertilizer systems (60 kg ha-1 N + 100 kg ha-1 P, 300 kg ha-1 Bio-organic (organic fertilizer), 3 kg ha-1 Bioumik (biofertilizer), 30 kg ha-1  N + 50 kg ha-1 P + 150 kg ha-1 Bio-organic fertilizer and 30...

Traditional agriculture in rainfed uplands of India has been experiencing low agricultural productivity as the lands suffer from poor soil fertility, susceptibility to water erosion and other external pressures of development and climate change. A shift toward more sustainable cropping systems such as conservation agriculture production systems (CAPSs) may help in maintaining soil quality as we...

in order to study the weeds frequency and dry matter in corn and cowpea sole cropping and intercropping systems, an experiment using replacement and additive techniques was conducted using different combination of intercropping in seven levels with ratio of 1:1 (50% corn + 50% cowpea), 1:2 (33% + 67%), 2:1 (67% + 33%), (100% + 20%), (100% + 10%), 100% corn and 100% cowpea, two levels optimal an...

to study the effect of strip intercropping pattern with cowpea and soybean on sorghum fodder yield an experiment was conducted at research farm of university of tehran (karaj) during 2005. the experiment was arranged in a randomized complete block design of four replications. the plant proportions included pure culture of sorghum (sss); cowpea (ccc) and soybean (ggg) each in 12 rows; vs differe...

introduction weeds are main factors reducing crops yield, especially under organic farming conditions (). it has been reported that weed populations are more in organic farming compared to conventional cropping systems, resulting in more reduction of growth and yield. although the chemical control is a fast and effective way for controlling weed populations, some negative impacts of the recent ...
