Lack of sufficient attention to the problem of loss by the Egyptian agricultural policy to the lack of reliable objective estimates of it at various stages, The official statistics do not provide accurate and detailed data. The data on losses in the various operations are very necessary for the development of sound policies for the maintenance of agricultural production, The problem of the study is the existence of a large loss of the wheat crop, and the failure to implement clear and specific programs in an appropriate manner to reduce the loss of it, with inefficiency in the performance of agricultural operations, The most important factors were the effect on the loss of cultivation of this crop in Sohag governorate, which is the quantity of production and the delay of the planting time. When the production increases and the farms delay planting wheat in November, the loss of wheat yield is about 4.98 and 6.23 kg / feddan. The most important factors affecting the loss of harvesting wheat crop are increasing the amount of production as the increase in production leads to increase losses about 6.37 kg / feddan, While the appropriate time during the month of May leads to reduce the loss of wheat harvest about 13.67 kg / feddan, As for the two factors affecting the loss of the wheat yield in Sohag governorate, what is the quantity of production and the date of harvest, as the increase in production leads to increase the losses about 4.43 kg / fed, while the farmer committed to the appropriate harvest times, which lead to reduction of feddan losses of wheat yield of about 14.56 kg /feddan. As for the factors affecting the loss of drying of the wheat crop, the quantity of production and harvest in May, as the higher the production increased the loss of about 3.65 kg / fed, and as the farmer committed to the time of harvest helped reduce the loss of the wheat crop about 18.64 kg /fedan, With regard to the factors affecting the total loss of the wheat crop are the increase in production and the length of the drying period if, when using the previous inputs, the total loss of the wheat crop is about 20.18 and 23.45 kg/ feddan, respectively. It is recommended to study the stages of harvesting, drying, storage and transport in order to reduce the losses of wheat from the wheat crop by spreading the mechanization in the harvest, as well as cultivating varieties characterized by the non-diversion of the ears during the circulation from agriculture to the transfer to stores or distribution to wholesalers, as well as the dissemination of audio aids and visual aids and a lot of extension centers to increase awareness of farmers importance Reducing the losses of the wheat crop and its contribution to increasing the productivity of wheat for wheat.
