Studies on Seed Viability of Some Cowpea Cultivars Inoculated with Single and Mixed Virus Isolates

This research proposed at fact-finding and checking the belongings of bacterium contaminations on beginning character of few picked 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 ocean’s surface) located in the Southern Guinea Savanna district of Nigeria to obtain this. The home was emptied, ploughed, devastated and crinkled at 0.75 m separate before graphic into plots and replications. The trial was a randomized complete block design (RCBD) copied three periods. Three cowpea children of each cultivar were planted subsequently fertilizer accompanying Apron – star (methylthiuram + metalaxyl + carboxin) at the of rate 3.0 kg beginning per 10 g of the poison. Seeds were planted at an event and inter–row organize of 0.30 × 0.75 m ahead the hills and later diminished to two per stand at 2 weeks subsequently sowing (WAS). Four free tests were administered together, for alone and assorted contaminations. Twenty-five cultivars of seedlings were introduced at 10 days later sowing (DAS) for the alone circulating quickly contamination and at 17 DAS for the assorted bug contamination. Seed animation was driven at the Crop Production Laboratory, Department of Crop Production, Federal University of Technology, Minna, Nigeria. The results presented that all the test cultivars were naive to sole and assorted contaminations of two together viruses but to various levels. The being of sources from alone contamination accompanying CMeV was slight in few instances, still, test of increased getting along for four weeks determined that source vigour was dangerously injured as distinguished to the added three bug situations even when sources being was small in amount injured. The test cowpea cultivars further written hardly any pods accompanying weak source yield in two together alone and assorted bug contaminations.
