Pot experiment was conducted in the year 2010 and repeated in 2011 to examine the effects of organic manure (poultry, cow dung and domestic waste) and inorganic manure (NPK 15:15:15) on the yield, soil and root population of Meloidogyne incognita-infected Ethiopian egg plant Solanum aethiopicum in a greenhouse at Kabba college of agriculture, Ahmadu Bello University, Kabba, Nigeria. Each of the organic manure was applied as soil amendment at the rate of 5t/ha and the inorganic fertiliser (NPK) was applied at the rate of 200 kg/ha, while there was an untreated control that acted as standard check. The experimental design was a completely randomised design comprising of five treatments including control and each of the treatments was replicated four times. The result of the experiment showed that all the organic manures considered and NPK fertilisers were effective in suppressing the nematode's negative effects on the plant, as shown by the improved yield, reduced soil and root population as well as reduced gall index of the organic and inorganic manure-treated plant compared with the control. The mean fruit yield of the manure-treated plant was of the range 18 ± 1 fruits and NPK fertiliser had an average of fruit number of 17, while the untreated control recorded an average fruit number of 6.5. The organic and inorganic manure-treated plants recorded bigger fruit size compared with control, and are significantly different from the control. The soil and root population as well as root gall index are reduced in all the manure treatments compared with the control and are significantly different from the control. The result of this experiment confirmed that organic manure can be utilised to manage nematode in soil endemic with root-knot nematode M. incognita.
Background: Sphenostylis stenocarpa is an underexploited African indigenous food crop that is enriched in nutritional quality. Objective: Exploring the robust genetic base of this landrace can help to maximize the benefit of the agricultural sector on the economy through production that is enhanced by packaging and patent. This as well will increase the quality of food production and promote African campaign on food sustainability. Methods: Upon this, this research made use of multiple statistics to identify S. stenocarpa yield and nutritional trait relatedness that supported selection for maximum yield and nutritional trait output. Yield and related traits including protein and oil contents of twenty-three Sphenostylis stenocarpa landraces were studied under a four year planting seasons in Teaching and Research farm of Landmark University, Nigeria. Results: Trait variances from Landrace × Year (L × Y) interaction, Principal Component and Cluster analyses were evaluated and the variation patterns were identified. Some vegetative (maturity phase, height and branching) and yield traits (Pod traits, seed yield and oil content) correlated significantly (p < 0.05) in the L × Y interactions. This suggests the usefulness of these traits in improving S. stenocarpa grain and oil quality yield. Tuber and nodule yield including protein content did not differ significantly in the variance table. Conclusion: The result indicates that one location trial is insufficient to determine such trait performance. The first four PCs that accounted for 51 percent of the total variations were traceable to branching, maturity date, pod numbers, seed and oil content as main contributors to yield.
The effects of neem compost on root knot nematode, Meloidogyne incognita, pest of Lagos spinach, Celosia argentea, cv. TLV 8, was studied during 2010 and 2011 planting seasons on the field. The trial was conducted at the Teaching and Research Farm of Ladoke Akintola University of Technology, Ogbomoso, Nigeria. There were four treatments, replicated five times fitted into randomised complete block design. Neem compost was applied at 1.0, 1.5 and 2.0 tonnes/ha. Experimental plots, where no compost was applied served as the control. The result obtained shows that Lagos spinach treated with neem compost significantly ( p < 0.05) reduced the final soil nematode population and root infections (damage), with resultant improvement on crop growth and yield. The result of the chemical analysis of the neem compost revealed the presence of flavonoids, sterols, glycosides, alkaloids and saponins.
