Application of soil and plant analysis to nutrition of tomatoes in south west Nigeria


, : Application of soil and plant analysis to nutrition of tomatoes in south west Nigeria. Acta Horticulturae (53): 235-247

Plant nutrient requirements were determined by soil, leaf and plant analysis. Organic C, total N and nitrate-N were used as indexes of available N. Critical levels by these methods were 9 p.p.m. of NO3-N, 2% C and 0.1% total N. The P sorption capacity of soils determined at a standard concentration of 2 p.p.m. of P was more suitable than the Bray 1 method for assessing available P. Critical sorption value was about 6 p.p.m. of P. Critical K level was 12 mg K/100 g of exchangeable K.

In this study 2000 normal cats, 50 cats with diabetes and 100 cats with a history of dehydrational crises were examined ophthalmoscopically to determine presence of cataract. The cats examined were predominantly from veterinary hospital population...

The objective of the current study was to investigate whether blood-brain barrier (BBB) permeability studies in vitro could be accelerated by running several compounds together in the same experiment. Methods. To address this question, we...
