Ireduce inadequacy of family income and enhance rural livelihoods. A Multiple Cropping Technology (MCT) of mixture of maize + groundnut + Cajanus Cajan in the same piece of field was introduced to farmers in Balungu, Gbane, Gbeogo, Sheaga and Yameriga villages in Upper East Region of Ghana. The Traditional Usual Technology involving sole maize or sole legume was the control. A total of 10 farmers per village formed the group of 50. Ridges were constructed using bullock/ camel attached to locally fabricated plough /ridger. Ridges were approximately 50 cm apart. Two seeds of maize were sown per hole at 50 cm apart, giving a total of 80,000 maize plants/ha. One groundnut seed was planted per hole at 50 cm apart with a total of 40 plants /ha. Cajanus cajan seeds were drilled lightly along at a rate of 25 kg ha-1. Maize was planted in the first ridge, groundnut in the second and Cajanus Cajan in the third ridge. The crops were repeated in the same order to cover the field. Soil samples were collected from farmers? field to a depth of 0 ? 40 cm for routine soil laboratory analysis. The soils in the villages are mostly loamy sand, strongly acid to acid in reaction, characterized by moderate organic carbon content with low nitrogen. Available phosphorus moderate with very low to low exchangeable bases, unlike yielded under TUP, yield under MCP increased in the second year. When the second year production in MCT was compared with TUP groundnut was 188 %, 180 %, 142 %, 148 % and 127 %, significantly higher in Gbane, Yameriga, Dbeogo, Balungu and Sheaga respectively. The corresponding values for maize was 402 %, 297 %, 310 %, and 148 5. Cajanus cajan is an additional crop introduced for both livestock and human with the stem used as domestic fuel wood.

Nicarbazin is an anticoccidial used in poultry production. Its residue of concern left in chicken meat is 4,40 -dinitrocarbanilide (DNC) whose content can be reduced through meat thermal processing. Thermal analysis techniques can be considered to elucidate how DNC degradation proceeds. This study aimed to investigate the thermal behavior of DNC using TG-DSC-MS and Py-GC-MS. TG-DSC-MS data showed that DNC decomposition occurs in a single step (252-280 C) as an endothermic event (DH of 670 J g-1). Fragments detected at m/z 43, 44 and 65 indicated the release of isocyanic acid, carbon dioxide and 4-nitroaniline as breakdown products. In addition, Py-GC-MS analysis confirmed that DNC is thermally degraded above 250 C generating 4-nitrophenyl isocyanate and 4-nitroaniline as the major pyrolysis products. Findings obtained from thermal analysis herein are useful to better comprehend the DNC disappearance after submitting chicken meat to heat processing. |
