| The effect of soil solarization during 30 days and the fertilize with goat manure to the soil at the rate of 0,20 and 40 t ha-1 was studied; the objective of this experiment was to increase soil temperature in order to study its effect on weeds population and on muskmelon yield. Solarization produced maximum soil temperatures of 55°C and 44°C at the depth of 1.5 and 10 cm respectively, which in turn clearly reduced the emergence and growth of weeds in solarized plots. Goat manure only increased soil temperature by 1.5 to 2.5°C, but it had an apparent antagonist effect on weeds density, however, this effect was not clear on solarized plots. Perennial weeds like Cyperus esculentus was affected but not eliminated by solarization. The effect of high soil... |

| This study analyzes the relationship between the changes in the energy balance components and the muskmelon stomatal resistance under plastic mulch conditions. This experiment was conducted in a muskmelon crop with and without plastic mulch, from April to July, 1998. To measure the energy balance components (net radiation (Rn), latent heat flux LE, sensible heat flux H and surface soil flux G). Eddy covariancestations were used; one was located in the plastic mulch section and the otherin the section withno plastic mulch.Each stationconsisted offast response kryptonhygrometer, aonedimensionalsonic anemometer anda fine wirethermocouple. The stations also have a net radiometer, 2 soil heat flux plates and two soil thermocouples of 4 parallel ends. The... |
