Most important feature of the storage systems is to preserve the integrity of the grain for a given period with minimal loss in quality and quantity. The main objective of this study aimed to choose the proper conditions which ensure safe storage process using infrared heating at the optimum radiation intensity of 882.67 W/m² and exposure time of 15 min and the ultraviolet radiation at radiation intensity of 3.538 mW/cm² and exposure time of 40 min on storability of cowpea seeds using different types of plastic hermetic bags in comparison with polypropylene (pp) woven bags. The changes in cowpea seeds quality during storage of pre-treated cowpea seeds in terms of moisture content, protein content, total microbial count and insect detection were also determined. The results show that, the moisture content of seeds stored in pp woven bags increased in contrast with both types of studied hermetic bags, oxygen concentration for hermetic bags decreased during storage period and carbon dioxide increased unlike pp woven bag, The rate of seeds infection with microorganisms and weevils was lower comparing with the samples stored in both types of hermetic bags and crude protein content of seeds stored in hermetic bags reduced at a very slight rate in comparison with that stored in woven bag.

Is the potato crop vegetables Home in Egypt, which is cultivated annually in the lugs of the three (Winter, Nile and Summer) total area within the limits of 450 thousand acres and estimated the haulm of potatoes for the area cultivated about 1,575 million tons with an average of about 3.5 tons per acre of haulm potato. Field crop residues have become a heavy problem of the Egyptian farmer. To get rid of this trouble, being resorted out burned in the open field. Where as some farmers use these as heels, as rich get fern it a media for spreading diseases. That causes environmental disaster and dangerous healthy problem. Potatoes haulm around 8 - 9 % of the total residues (18-25 million tons annually). The trails are conducted at Gemmza Research Station, ARC under the four levels of drum speed (1000, 1200, 1400, and 1600 rpm), & (48 and 68) number of knives and three feeding rates (600, 800, and 1000 kg/h), to measure the mean weight length, fuel consumption, power consumed, energy-consuming and machine performance efficiency. The mean length cut weight between (6.608 and 10.627 mm) resulted. This objective of this research is to identify the appropriate mean weight lengths suitable to submission to the different animals, either small animals such as rabbits, medium animal such as goats, sheep or large animals such as cows and buffaloes.

Rice threshing is one of the important factors affecting grain losses, quality and quantity. The wearing of the secondary threshing drum forks and bearing occurs crop blockage inside the threshing housing that lowers the combine harvester field capacity and increases the total grain losses. To overcome this problem, this study aimed to modify the combine harvester rice threshing device by replacing the secondary drum forks with knife blades. The combine harvester was evaluated using the modified drum, compared with the original drum. The tested treatments were rice grain moisture content (20%, 23% and 25% d.b.) and operational time (50, 100, 150 and 200 hrs.). The experiment was established and statistically designed as a factorial completely randomized block design with three replications. The obtained results revealed that modified secondary drum achieved lower values of wearing rate, lower values of rice grain total losses and higher values of threshing efficiency, compared with the original drum. So, it is recommended to use the modified secondary drum, especially at 23% grain moisture content and 50 hrs. operating time. [ABSTRACT FROM AUTHOR]
