Empirical assessment of short-term preferences of tropical forages by crossbred bull calves

  Short-term preference studies were carried out with growing calves based on diets of local grass forages found in Turiani division, Morogoro, Tanzania. Four intact crossbred male calves aged 7 - 8 months and weighing 82.75 kg were used. Four grass species were provided either singly [Panicum maximum (T1), Panicum trichocladum (T2), Pennisetum purpureum (T3)...

Influence of nitrogenous fertilizer plant effluents on growth of selected farm crops in soils polluted with crude petroleum hydrocarbons

  Nitrogenous fertilizer (NPK) plant effluents from NAFCON were used in amending plots of land experimentally polluted with crude oil. Results obtained showed that NPK served as a good soil for the natural removal of contaminating crude from soils. Crude oil disappearance in untreated plots ranged between 8.70 and 34.80% and 20.90 and 60.50% for treated plots; cumulative loss was 73.0%. The disappearance was...

Light-induced transient dormancy in Cleome gynandra L. seeds

  Events associated with dormancy release during seed germination still require explanation. The objective of this study was to examine seed responses during germination of Cleome gynandrain the presence or absence of light and at constant or alternating temperatures. Germination of C. gynandra seeds at 20oC was inhibited by light, but it was improved at 20oC in darkness. There was no...

Comparative evaluation of vertebrate pest damage on some newly developed quality protein maize (QPM) varieties in south-western Nigeria

  Six newly developed Quality Protein Maize (QPM) varieties were subjected to natural vertebrate pest infestation in Ibadan South-Western Nigeria. Data taken were statistically analyzed while probably level was set at p<0.05. Results of the experiment revealed that ILE-1-OB maize variety with the mean yield of 1.3 t/ha recorded the highest rodent damage of 2.77% while ART 98 SW4-OB with 0.74 t/ha recorded a...

Management of black pod disease of cocoa with reduced number of fungicide application and crop sanitation

  Black pod disease caused by Phytophthora megakarya is the most important fungal disease on cocoa in Ghana. The current recommended control method of combining sanitation practices with 6 - 8 fungicide applications in a year is considered unfriendly to the environment, too expensive and time consuming. Consequently, fungicide adoption rate by farmers is extremely low. Studies were therefore...
