You know the PBR Cowpea
has been granted environmental release, which means that the Nigeria Biosafety Agency has studied the data provided, sat down and looked at the cowpea
and confirmed that the beans is safe for human consumption and animal consumption, and also poses no serious danger to the environment.
Vouchers were used to redeem the seeds of staple crops like millet, sorghum and cowpea
as well as high-value cash crops like groundnut.
The crop residues used were [sup.15]N-labelled and unlabelled residues of cowpea
(Vigna unguiculata (L.) Walp.), a summer cover crop widely used in Southern Brazil.
Grain yield of cowpea
in the northeast region of Brazil is relatively low due to the low-cost technologies applied, with values ranging from 300 to 400 kg [ha.sup.-1] (Soares et al., 2006; Freire Filho et al., 2011).
Several insect pests feed on cowpea
causing significant damage at different phenological stages of the plant.
During the whole productive process, the cowpea
crop is attacked by several insects.
Mean comparison revealed that the greatest millet grain yield was obtained from plant sprayed with nano-iron at concentration of 3adeg and millet sole culture equals to 1021.33 kg ha-1 and the lowest millet grain yield was obtained from non-sprayed plant and 100% millet+20% cowpea
equals to 442.83 kg ha-1.The results of the experiment confirmed that nano-iron chelated was effective on intercropping of millet and cowpea
, so that plant sprayed at concentration of 3adeg had greatest morphological characteristics and yield of the both crops.
Even though black-eyed peas are more popular, cowpea
cultivars such as 'Big Red Ripper,' 'Whippoorwill,' 'Sea Island Red,' and 'Mississippi Silver' have more flavor, better texture, and richer character by far.
In spite of the significant contribution of cowpea
to the nutrition and food security in Ghana, yields and the production of the crop in the country are very low and continue to decline over the years.
The trainings were conducted in Palawan, Albay, Sorsogon, and Oriental Mindoro, which led to the identification of possible collaborators of the project.Evaluated seed performance of the different varieties and results showed that cowpea
(Vigna unguiculata L.) is an annual legume crop widely grown in East Africa .
is used in controlling soil erosion due to its tendency to produce a heavy vegetative growth that provides full ground cover.
butachlor+dhaincha+1 HW, butachlor + 2 mechanical weeding, butachlor + cowpea
+ 1 HW, 2 HW and weedy check as sub plot treatments.
Several scientists have been working with cereal- legume intercropping systems and proved its success compared to the monocrops  Some studies have indicated that intercropping was more productive than sole cropping because of the complimentary effect of intercrops such studies included amaranth with cowpea
, cucumber with cowpea
, maize with cowpea
 and cassava with cowpea
