Studies on Seed Viability of Some Cowpea Cultivars Inoculated with Single and Mixed Virus Isolates| Chapter 12 | Research Highlights in Agricultural Sciences Vol. 6

 This research proposed at investigating and analyzing the effects of bacterium infections on children quality of few selected cultivars of cowpea. Thus, a field study was transported at the Teaching and Research Farm of the Faculty of Agriculture, Ahmadu Bello University (ABU), Zaria, Mokwa Station (090211 N and 50135 E, 201 m above sea level) located in the Southern Guinea Savanna zone of Nigeria to gain this. The site was emptied, ploughed, harrowed and crinkled at 0.75 m apart before marked out into plots and replications. The trial was a randomized complete block design (RCBD) copied three opportunities. Three cowpea seeds of each cultivar were planted after fertilizer with Apron – star (methylthiuram + metalaxyl + carboxin) at the of rate 3.0 kg children per 10 g of the fungicide. Seeds were planted at an intra and inter–row organize of 0.30 × 0.75 m along the hills and later thinned to two per stand at 2 weeks following in position or time sowing (WAS). Four independent troubles were conducted together, for single and assorted infections. Twenty-five cultivars of seedlings were introduced at 10 days after sowing (DAS) for the sole viral contamination and at 17 DAS for the mixed bug infection. Seed being was determined at the Crop Production Laboratory, Department of Crop Production, Federal University of Technology, Minna, Nigeria. The results presented that all the test cultivars were susceptible to alone and mixed contaminations of the two viruses but to various levels. The viability of sources from single contamination with CMeV was slight in few instances, also, test of increased ageing for four weeks registered that source vigour was seriously injured as compared to the additional three virus situations even when seeds being was not much injured. The test cowpea cultivars also written fewer pods accompanying poor source yield in both distinct and mixed bug infections.
