This book was released on 1985 with total page 122 pages. Available in PDF, EPUB and Kindle. Book excerpt: Glyphosate [N-(phosphonomethyl) glycine] was used as a preharvest desiccant on cowpea (Vigna unguiculata (L.) Walp) in greenhouse and field studies in 1982, 1983 and 1984. Various stages of pod development were selected and tagged at the time of herbicide application in order to make comparative studies of the effect of the herbicide on biochemical components of the seeds.
Book Synopsis Evaluation of Cowpea (Vigna Unguiculata L. Walp) Genotypes for Adaptation to Low Soil-phosphorus Conditions and to Rock Phosphate Application by : Sabiou Mahamane

Walp) Genotypes for Adaptation to Low Soil-phosphorus Conditions and to Rock Phosphate Application written by Sabiou Mahamane and published by . This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Cowpea (Vigna ungiculata L. Walp) is a major food and fodder legume in poor countries, particularly Sub-Saharan Africa countries. It is generally produced in sandy, acid soils, deficient in phosphorus (P) which severely limits its production. Because processed phosphate fertilizers are expensive and poorly available to farmers, rock phosphate is viewed as a cheap alternative phosphate source. The present study evaluated 696 U.S Core Collection and IITA cowpea accessions for adaptation to low soil P environments and for response to rock phosphate application. Subsequently, organic acid exudation by selected cowpea genotypes as a mechanism for P acquisition from Fe-oxide and Ca bound P was investigated. A low P soil from Nacogdoches pine forest was used to grow plants. There were two P treatments: 0 and 300 mg P/kg of soil as Tahoua (Niger) rock phosphate. At harvest, plant height, shoot and root dry weights were determined and total biomass and shoot-to-root ratios were computed. Shoot P contents of 100 selected accessions were measured. Sixteen accessions reflecting the wide array of responses observed were selected for the organic acid study. Plants were grown in a growth chamber hydroponically with no P and +P nutrient solutions for 3 weeks. Organic acids were collected in a CaCl2-KCl solution. The nature and quantity of the collected organic acids was determined. Cowpea accessions were significantly different in their ability to adapt to Pdeficiency stress and to acquire P from rock phosphate. The parameters most effective in separating the accessions were shoot mass and total biomass. This data will be potentially useful in the selection of cowpea germplasm for (1) adaptation to West African soils of low P fertility, and (2) ability to utilize P from poorly soluble rock phosphate. The predominant organic acid exuded by cowpea roots was a tricarboxylic acid not yet identified. There was surprisingly more exudation of this acid under +P than under -P conditions. Exudation was more highly correlated to roots than to shoots.

This book was released on 1991 with total page 172 pages. Available in PDF, EPUB and Kindle. Book excerpt: Field and laboratory experiments were conducted to evaluate the relationship between seed specific gravity, and/or seed density, to the phydiological quality, storability and seedling performance of cowpea seeds. Two methods of seed separation were used: a) separation using aqueous sucrose and b) using a table model fractionating aspirator. Seeds of different specific gravity separated by sucrose solution were compares using a standard germination test at 20-30oC and accelerated aging tests at temperatures of 40oC, 42oC, and 45oC for 48 and 72 hours. Germination responses indicated that low specific gravity seeds perform poorly when compared to high specific seeds and to the unseparated sample. However, seed vigor responses expressed by the accelerated tests results revealed significantly higher vigor for the unseparated sample than for any of the specific gravity classes, suggesting that the use of aqueous solutions for cowpea seed separation may have a detrimental effect on seed quality possibly due to water absorption during separation. Field emergence results in 1988 were not significantly different among specific gravity categories. In 1990, field emergence responses were similar to results obtained in the accelerated aging tests. The unseparated seeds were superior to the seeds which were separated using solutions. However, differences in yield in both 1988 and 1990 planting seasons were not related to seed specific gravity. The evaluation of the relationship between seed density expressed by 100 seed weight and storability of cowpea seeds was determined different density fractions obtained using a fractionating aspirator. Evaluations were conducted prior to storage and after 6, 9 and 12 months of open storage using the standard germination test, first count germination, accelerated aging test, and germination performance at low temperature. Vigor was also evaluated by comparing seedling elongation characteristics. No significant differents were observed in germination percentage for all categories prior to storage. However, tests conducted after each storage period revealed significantly higher germination for the high density seeds as well as for the unseparated control.
