Abstract
In light of the discussion of the impact of dust on the phenomena of the atmosphere of Agriculture early tomato crop in the district Alچbaic can conclude the following: 1 - came on the ass the first prize in terms of area invested in agriculture early crop of tomatoes in the judiciary as it stood at (750 acres) and by (75%) whereas that came on the Panthers came in second with an area (250) acres, and by (25%), while it did not appear Agriculture early tomato crop in the center of Alچbaic. 2 - early tomatoes are grown in the last week of June and will continue in the first weeks of the month of August, and thus are vulnerable to extreme weather dust because these months are considered the top in terms of recurrence of the phenomena of atmospheric dust. 3 - tomatoes are grown in two ways The first is the early development of seeds in containers alone or in flat boxes and then transported to transplanting in the field. The second method, they are sowing the seeds directly in the field, and so it would be subject to the impact of the phenomena of air and dust in spite of this, the majority of farmers follow this method. 4 - The months of June and July and August months the summit in a recurrence of the phenomena of atmospheric dust in the province as Astathera B (42%) of the total dust stuck in the province of $ (115.8) days, and by (56%) of the total dust and sand storms in the province and of ( 22.5) days, and by (44.7%) of the total dust upward of $ (104.1) days in the province. 5 - affect the phenomena of atmospheric dust on agriculture, the early crop of tomatoes through the accumulation of minute dust on the leaves of traditional birth attendants and their parts vegetative as well as the effects from the blowing winds speed associated with the storms of dust, and in general the effect of the phenomena of atmospheric dust on the traditional birth attendants early through direct damages and indirect . 6 - phenomena that affect the air dust directly on the traditional birth attendants during the early part of the impact on all vital events and processes of photosynthesis and respiration and transpiration. 7 - affect the phenomena of atmospheric dust, indirectly through the material losses suffered by farmers as a result the death of traditional birth attendants and delay maturity of winning and the incidence of diseases or by damage caused by pipes and drippers, engine pump, plastic sheeting as well as service operations performed by the farmer. Recommendations: In light of the facts that have been reached following recommendations can be proposed to appoint perhaps in the solution or mitigation of some of the problems facing agriculture early in the judiciary and the resulting impact of the phenomena of air dust. 1 - the need to delay the date of Agriculture (sowing seeds) from the last week of June to mid-August and thus Stahl midwife at the end of August or in the early days of the month of September in order to avoid the occurrence of dust storms summit. 2 - The need to follow the first method in agriculture, the development of individual seeds in containers or boxes and flat so as to protect the seeds from the impact of dust weather phenomena. 3 - the need to create buffers for wind from the trees that reduce wind speed loaded a few minutes the dust and mitigate its impact, and It should be noted that studies indicate that these trees that reduce wind speed Alhabh to more than half the speed at the opposite side, it was found that the wind which speed of 65 km / h before the bumper fall to about 30 km / h after passing the source (31). 4 - The need watering traditional birth attendants in the event of the phenomena of air and dust so as to maintain the humidity necessary, in addition to maintaining the wet pipe in order to protect it from breakage. 5 - the need for irrigation pumps in buildings, especially in order to protect it from dust impact phenomena of the atmosphere.
