dc.description.abstract This study has analyzed both the design and environmental problems and the problems of fertilizers and pesticides (their relationship to disease, insects and pests) and its impact on productivity, then the representation of the appropriate solutions in the form of technical proposals to improve the performance of greenhouses under the hot summer climate in the state of Khartoum conditions of the new productivity and compared the resulting after optimization productivity process old .Taking in our considerd the standard conditions as a reference for comparison process has done. After field visits we have acquired on the temperature readings , relative humidity and the intensity of solar radiation by device and its enhancements , we found that ( average temperature is 31.5 degrees Celsius , the relative humidity is 60 % and the intensity of solar radiation is 350 watts per square meter ) and after adjustment we have acquired on readings ( average temperature of 29.2 degrees Celsius , 65% relative humidity and solar radiation density of 250 watts per square meter ) and thus an increase in productivity of crops by tomatoes and cucumbers (20% ,14.9% ), respectively . en_US
