Abstract

In order to decrease the application rate and chemical in Varamin province, have been payed excessive cost for SPRAYING of COTTON field each year. It take place because of the absence of a suitable farm machinery calendar. The aim of this study is: 1-Collecting required informations about limiting factors for SPRAYING 2. Determining permissive limits of limiting factors for SPRAYING. 3-Recognizing and determining time limits for controlling of pests diseases and weeds of COTTON field. There are limiting factors for air and ground SPRAYING. The most important of which, as mentioned in this study are rainfall, wind, temperature and relative humidity. The authorized limits of any of these factors have been determined. Since in this study, description and analysis of the data collected from the studied community were intended, first a measure was taken to gather a ten year period data (94 -2008) from local weather station. To analysis these data, a policy was made to divide each month into six sections with five day. (Months with 31 days have one 6 day section each on their last columns). Then, taking the authorized limits of limiting factors into consideration, the numbers of suitable WORKING DAYS were determined for each month. Given the typical theory and the materials used in variables, t- test was used to measure the possible limits of means.After the analysis of data, it was made known that the most limiting factor in the region was the temperature that influenced in determining the number of WORKING DAYS. The total suitable WORKING DAYS were set to be 18.2 days based on this limiting factor.
