AKANDE, M. O; MAKINDE, E. A  e  OTUWE, M.O.. Dry matter partitioning of sesame and nutrient dynamics with organic and inorganic fertilizers. Trop. subtrop. agroecosyt [online]. 2011, vol.14, n.3, pp. 1063-1069. ISSN 1870-0462.

The dry matter partitioning of sesame with organic and inorganic fertilizers was assessed in a pot experiment. Treatments consisted of sole and combined applications of poultry manure and NPK 16-16-16. Complementary application enhanced dry matter yield. Shoot yield ranged from 1.2 to 2.8kg while root dry matter yield ranged from 0.5 to 0.9 kg. Total dry matter yield ranged from 1.7 to 3.5kg. Highest K content of 0.36% occurred in plants treated with sole 100 kg NPK ha-1 and the lowest of 0.03% from the control plants. Calcium content increased from 0.09% in control plants to 0.37% in plants treated with 5 tons ha-1 PM. Magnesium content ranged from 0.01% in the control plants to 0.04 % in plants treated with application of 100kg NPK ha-1. Sodium ranged from 0.07% to 0.13%. Phosphorous increased from 0.33 % to 0.83 % in plants treated with 50kg NPK ha-1.
