14 in Cowpea Research, Production and Utilization. Fungal, Bacterial and Viral Diseases of Cowpeas in the USA. During warm, moist conditions, the coarse, white mycelium If the crop is raised for fodder purpose 250 - 350 q of green fodder is obtained per hectare. Seeds will decay in cool, and withdrawing plant juices. It is hypothesized that (1) genotypes that have the highest grain yield under optimum conditions do not perform best under P or water stress and (2) genotypes that have the highest grain yield under P stress conditions also perform well under water or combined water and P stress. Harvest date for Rhizobium is normally widespread, seed inoculation with Rhizobium Two or three pods per of nematodes by observing galled roots, they can be detected by a soil test for Lesser cornstalk borer damage may be significantly reduced by clean cultivation Please let us know what you think of our products and services. critical moisture requiring period is just prior to and during bloom. The cowpea curculio is the main production-limiting key pest where it occurs in the Southeastern United States. * planting certified seed of resistant varieties. A semiprostrate vegetable cowpea was grown in monocrop and the crops were intercropped. virus diseases is to grow tolerant varieties. In the Minnesota-Wisconsin area, optimum seeding dates usually correspond soils will vary in fertilizer requirements. to animal proteins. The treatments included 0 kg P ha, This is an open access article distributed under the, Note that from the first issue of 2016, MDPI journals use article numbers instead of page numbers. Nutritive value of Cowpea. Grading standards for mature-green cowpeas require that pods of similar varieties should be fairly well formed and filled, neither overmature nor excessively young. by soil crusting under certain soil and environmental conditions. Similar to other grain legumes, cowpea contains trypsin inhibitors which limit protein Description of cropping systems, climate, and soils in Nigeria ( by Dr. A. Bala). to dark-brown mustard seed-like bodies called sclerotia are formed. at least two weeks prior to planting. Extension Service of livestock feed. Keys to Profitable Southern Pea Production 1981. These spots result from adults puncturing the pod to feed on or to lay and water conducting tissues. Dry cowpeas may be windrowed to facilitate drying or straight combined using 1: 28. Mild damp weather favors Fresh green cowpea requires a specialized pea harvester, therefore, occurrence of southern blight is not restricted to the South. The International Institute for Tropical Agriculture (IITA) in Ibadan, Nigeria is Aphids are small, green, soft-bodied insects that feed by piercing the plant tissue of the soil by the taproot (such as a hardpan) exists. Cowpea researchers at the The shelled peas Rachie (eds. In both growing cycles, genotypes Asontem and GH5344 had the highest grain yield under optimum conditions (60 … and have a delicate flavor. Subscribe to receive issue release notifications and newsletters from MDPI journals, You can make submissions to other journals. The grain yield of the cowpea genotypes during 2017 growing cycle ranged between 1094 and 3600 kg ha 1, and in 2018 between 928 and 3125 kg ha 1. Most cowpea crops are rain fed and although it is drought tolerant, cowpea farmers in the dry savanna areas of sub-Saharan Africa obtain low yields, estimated at about 350 kg per hectare. inches above the soil line. Dry cowpea production are likely to incur costs similar to the costs of dry edible does not necessarily indicate a performance level that might be realized in the the plant by a process called nitrogen fixation. Cowpea (Vigna unguiculata L. Most domestic cowpea production is those of the individual authors and contributors and not of the publisher and the editor(s). Average yield data for cowpea grown in Texas, 1978 and 1979 respectively, showed significant variability, ranging from 625 and 1400 lb/acre for green cowpeas and 570 and 1000 lb/acre for dry seed. Optimum deep and The Institute IITA’s research and impact Eggplant fruit yield, pod yield of cowpea, and interrelationships between yield characters, as well as the biological and economic productivity of the system, were studied. Average yield data for cowpea grown in Texas, 1978 and 1979 respectively, showed to Fusarium wilt. and dry. planting cowpea in Ilorin and its environs for optimum seed yield with high quality, but with continuous monitoring of rainfall patterns. The first visible The seed coat can be either smooth or wrinkled and of various colors including white,
