African Journal of Biotechnology

Afr. J. Biotechnol.

The study was conducted to assess the suitability of soaked parboiled cracked maize as a carrier of I-2 vaccine for oral immunization of village chickens. Chickens were vaccinated once via ocular route and orally with cracked maize at the second and fifth weeks of the experiment. Post vaccination serum was collected 4, 7, 9 and 11 weeks of the experiment and haemagglutination inhibition test was done to evaluate the antibody titer. The results show... Read more

Intermittent leaching of copper from copper based fungicide through a saturated soil profile

Journal of Soil Science and Environmental Management

J. Soil Sci. Environ. Manage.

Copper is a micronutrient required for plant growth. However, it can have negative effect on plant growth if the concentration is too high. The aim of this study was to examine copper concentrations of leachate from soil columns treated with copper based fungicide. A 2 × 4 factorial arrangements consisting of two soil types (0 to 60 cm sample depth) and four rates of copper based fungicide concentrations (0, 1.88, 3.75 and 7.50 g/L ) was used... Read more

Comparative performance evaluation of different mechanical equipment for weed control in sugarcane crop in Northern-Western Tarai Region of Uttarakhand

African Journal of Agricultural Research

Afr. J. Agric. Res.

Manual weeding/ interculture in sugarcane is a common method adopted by the farmers, in Tarai region of Uttarakhand, for weed control. However, due to non- availability of labour especially during peak season, the weeding/interculture operation is jeopardized. Also the labour demand in sugarcane weeding is very high compared to other cereal crops making this operation expensive. This study includes comparative performance evaluation of three... Read more
