dc.description.abstractThis study examined the effects of microclimatic conditions on the early growth of Jatropha curcas seedlings in Kano, Nigeria. The experiment was conducted between 20 April, 2014 and 14 July, 2014. Microclimatic condition values were recorded using two Lascar EL- USB Data Loggers, one at each of the two treatments (shade and sun). Early growth characteristics of Jatropha curcas seedlings at both shade and sun treatments were recorded at 2, 4, 6, 8, 10 and 12 weeks after sowing (WAS). Line and bar graphs were used to describe the microclimatic conditions and the early growth characteristics of Jatropha curcas at both shade and sun treatments. Pearson‟s product moment correlation was used to test whether there is significant relationship between the microclimatic conditions and the early growth characteristics of Jatropha curcas seedlings at the two treatments. Paired student t-test was used to determine if there is a significant difference in microclimatic conditions and the early growth characteristics of Jatropha curcas seedlings between the two treatments. All tests were carried out at 0.05 significant levels. The findings of the study revealed that the seedlings in the sun treatment grow faster and gave better results than their shade counter parts. This confirms the effects of sun light on plants and the vital role it plays especially during photosynthesis. The correlation results showed that there is a significant relationship between the micro climatic conditions and the early growth characteristics of Jatropha curcas seedlings in the sun treatment and also between dew and seedlings emergence in both shade and sun treatments however; it showed that there is no significant relationship between the microclimatic conditions and the early growth characteristics of Jatropha curcas seedlings in the shade treatment. The student t-test results showed that there is a significant difference in temperature, plant height, stem diameter, leaf count and crop growth rate between the shade and sun treatments. However, it showed that there is no significant difference in relative humidity, dew, seedlings emergence, leaf area, fresh weight and dry weight between the two treatments. Finally, it is recommended that Farmers or Entrepreneurs in the study area should raised Jatropha curcas seedlings in an open space to avoid shading effect as this will allow the seedlings to absorb more sunlight for photosynthesis and other growth processes.en_US
