Abstract EN

It is estimated that the rice cultivated area in Egypt is estimated at about 1.4 million feddans producing about 3 million tons of rice straw.

The same estimates indicate that the cultivated area of summer maize is estimated at 2.1 million feddans, which produces about 5.5 million tons of woodland (in 2013), Most of which are burned and not the maximum benefit.

The problem of research is to increase the amount of agricultural waste, especially for rice and maize crops, and not to achieve the economic efficiency of these quantities of agricultural, And the study of the development of the area cultivated for each of the maize, cotton, sesame, sorghum, lupine, black beans, sugar beet, rice and the total of these crops in Egypt during the period (2000-2016) the annual average of about 324.44, 460.06, 72.66, 354.76, 4.07, 1471.2, 298.88, 1452.41, 3114.4 and the total area of the maize crop during the study period.

The statistical significance of these equations was proved, while the sesame yield was not substantiated.

The development of the production capacity of the most important plant waste was studied in Egypt during the period 2000-2016.

The average annual production capacity of the maize, cotton, sesame, sorghum, lupine, peanut, sugar beet, rice straw, These crops are 5586.12, 871.06, 94.47, 4.53, 235.65, 1711.65, 3217.06, 3217.06 and 2634.6 tons respectively during the study period.

The 
general trend equations showed a decrease in the production capacity of cotton, sorghum and thermos.

While the production capacity of each of the sesame, peanut bean and sugar beet was increasing.

The statistical significance of these equations was not proved, nor was the statistical significance of the production of maize, rice straw and total production capacity of these crops.

The cost of feeding was about 13505.1 pounds, representing about 78.3% of the total average cost of the head, representing about 96.1% of the total average variable costs of the head of about 14049.2 pounds, and amounted to about 17574.8 pounds without the use of silage, which Indicates that the use of silage in nutrition leads to a reduction in feeding costs by about 4069.7 pounds per year, This is due to the lower daily costs of feeding the head of cows when using silage in feeding.

The cost of producing a ton of milk for dairy cows that used silage was about 3849 pounds, while the cost of producing milk for the head of dairy cows that did not use silage for about 13715.1 pounds, The production of milk is about 2805.4 kg, and thus the cost of producing a ton of milk for dairy mixtures that did not use silage about 4888 pounds, due to lower feeding costs for animals that used silage than not used silage in feeding.
