growth stages of cowpea

Faria, Rogério Teixeira de Drought at the preflowering stage in cowpea can reduce the yield potential by 360 kg/ha. Growth stages of cowpea (Vigna unguiculata) vis-a-vis seed transmission of viruses. Vegetative growth was more sensitive to water stress than flowering stage. 1993. and The mean rate of expansion of individual leaves increased with temperature proportionately more than the duration decreased, hence final leaf size increased with temperature. Muchow, R.C. A total of 58 cowpea (Vigna unguiculata L. Cardoso, Milton José Its root is a taproot which is quite strong and with many spreading lateral roots in surface soil. Littleton, E. J. Folegatti, Marcos Vinícius Squire, G. R. Cowpeas (Vigna unguiculata) and lablab (Lablab purpureus) are fast growing, annual, summer forage legumes.They are excellent quality crops for fattening both sheep and cattle, and are also regarded as good feed for milking cows. Chauhan, Y.S.

Several insect pests attack all growth stages of cowpea, but their economic importance is highly dependent on the environment [4, 5]. "metricsAbstractViews": false, Elstonff, J. Temperature affected this pattern. Othieno, C. O. 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. Green cowpea seeds are boiled as a fresh vegetable, or may be canned or frozen. Leaf area index increased quicker and leaf death started sooner during warm seasons.

Gregson, Keith "isLogged": "0", and Field studies were conducted to determine cowpea [Vigna unguiculata (L.) Walp.] Copyright © Cambridge University Press 1979, Hostname: page-component-77fc7d77f9-mhpm4 Walp.) In this experiment, short-term (7-d exposure) elevated temperatures significantly (P < 0.05) affected all three growth stages of cowpea (cv. Summary Cowpea, Vigna unguiculata was infested at the young, mid‐fill and mature pod growth stages with, respectively, one, two and three pre‐reproductive adult apterae of Aphis craccivora per pod in a screen house. Cowpea is a warm-season legume crop, mostly grown in humid tropical regions. Height and vegetative growth stages for COM and IAC were taken weekly starting 2 July 2014 until 13 Aug. 2014. The pattern of leaf growth and death was followed in stands of cowpea grown in the field at Ibadan, Nigeria. cowpea, and at later stages, the nitrogen fixation inhibitory effect of N 2.5 mM and N 5 mMis decreased. Individual leaves died while pods at the same node were filling. Cowpea is eaten by deer as forage, and is commonly used in food plots for deer. Varlett Grancher , C. & Bonhomme , R. ( 1974 ). and Whereas, under high temperature regime, cowpea growth was vigorous hence flowered and formed yield. The rate of leaf appearance increased with temperature and the duration of expansion of individual leaves decreased so that a constant number of leaves were expanding at one time. Soil Requirements for Growing Cowpeas: 27 March 2009. "languageSwitch": true, Plants are viny or semi-viny (indeterminate), and produce many trifoliate leaves that are smooth and shiny. Cowpea growth response to short-term elevated temperatures. View all Google Scholar citations It all depends on the type of season, if it is the rainy season, no water is given for the cowpea crop, before rainy season couple of irrigations are preferred in cowpea farming. Some varieties of cowpea are used specifically for wildlife purposes (Ball et al., 2007). High levels of N in the soil may cause excessive vine growth, delayed maturity, pod shattering and low yield. A. craccivora caused pod shrivelling at the young and mid‐fill pod stages, on which the aphid was more fecund. B. yuanmingense. Generally, field pests that cause significant losses in cowpea include the stem maggots ( Ophiomyia spp., Diptera: Agromyzidae), foliage beetles ( Ootheca spp., Coleoptera: Chrysomelidae), aphids ( A .
