“…Sustainability in food security within sub-Saharan Africa and Nigeria in particular, is dependent on development, improvement and preservation of crops, especially at this critical global threat to life occasioned by worsening climatic conditions [ 36 ]. It has been established that cowpea possesses the characteristic high variability, drought tolerance and adaptability to support food security [ 37 – 39 ].…”

Background: Assessment of genetic diversity of Vigna unguiculata (L.) Walp (cowpea) accessions using informative molecular markers is imperative for their genetic improvement and conservation. Use of efficacious molecular markers to obtain the required knowledge of the genetic diversity within the local and regional germplasm collections can enhance the overall effectiveness of cowpea improvement programs, hence, the comparative assessment of Inter-simple sequence repeat (ISSR) and Start codon targeted (SCoT) markers in genetic diversity of V. unguiculata accessions from different regions in Nigeria. Comparative analysis of the genetic diversity of eighteen accessions from different locations in Nigeria was investigated using ISSR and SCoT markers. DNA extraction was done using Zymogen Kit according to its manufacturer's instructions followed by amplifications with ISSR and SCoT and agarose gel electrophoresis. The reproducible bands were scored for analyses of dendrograms, principal component analysis, genetic diversity, allele frequency, polymorphic information content, and population structure.

“…Plant height was positively correlated (0.75, 0.89 and 0.55) with the single plant yield in all the environments. It was buttressed by Malik et al, (2007), Udensi et al, (2012) and Burno et al, (2017). On the other hand, plant height negatively significant with single plant yield was reported by Mebrahtu and Devine (2008) and Li et al, (2013).…”

“…More nodulation increases biological nitrogen fixation with maximum vegetative growth with broader leaves, the more leaf area that will be exposed to photysynthetic activity and more pods that will be produced which might affect the pod yield and ultimately seed yield. Thus integrated nutrient management approach contributes significantly to the final yield of cowpea by improving the soil properties and soil fertility making sustainbale production (Udensi et al, 2012) [19] .…”

Field experiment was conducted on clay soil during kharif season of 2014-15 at College farm, Latur, VNMKV, Parbhani, Maharashtra to study the effect of various sources of nutrients viz., organic manures, inorganic, biofertilizers and their combinations on growth parameters and yield attributes of cowpea (Vigna unguiculata L. Walp) cv. 'Konkan Sadhabahar'. The experiment was conducted in a randomized block design (RBD) and replicated thrice. The results revealed that significantly the maximum plant height (30.0 cm), drymatter production (17.5 g per plant), branches per plant (5.9), functionl leaves per plant (14.0) and leaf area per plant (12.1 dm 2 ) were recorded with the application of 75 per cent RDF + Bio-fertilizers + vermicompost @ 1.25 t ha -1 as compared to other treatments. In respect of yield per hectare and over all yield contributing factors viz., pods per plant (6.6), pod yield per plant (7.7 g), seed yield (1066 kg ha -1 ) and straw yield (2707 kg ha -1 ) recorded significantly higher in 75 per cent RDF+Biofertilizers + vermicompost @ 1.25 t ha -1 . The increased supply of N and P through organic manures, inorganic fertilizers and Biofertilizers like Rhizobium and Phosphorous Solubilising Bacteria (PSB) and higher uptake by plants contributed to increased rate of physiological processes in plant and led to higher growth and yield attributes. Correlation coefficients resulted significant positive relationships between growth, yield contributing traits and seed yield.
