Onion seed cv. Giza 6 " Improved " was treated with priming in salicylic acid, fungicide vitavax and salicylic acid + fungicide vitavax before packing in cloth, aluminum foil and polyethylene bags for 0, 3, 6, 9 and 12 month, after treatment. Seed moisture content %, germination %, seed and seedling vigor traits and fungi infestation% were recorded after each storage period. Seed treatments maintained onion seed quality as measured by; seed germination%, tetrazolium test, seed vigor (germination% after accelerated aging test and electrical conductivity, seedling vigor (seedling length and seedling dry weight) and fungi infection% comparing untreated seeds. Type of seed packing materials significantly affected seed moisture content and quality traits of onion seed. Aluminum foil and polyethylene bags maintained onion seed at low moisture content, fungi infestation, high seed and seedling vigor comparing cloth bags. Prolong storage periods from 0 to 3, 6, 9 and 12 months decreased germination%, viable seed, accelerated aging test%, seedling vigor traits and fungi infestation%. Treating onion seed by salicylic acid solution, fungicide vitavax and salicylic acid solution+ fungicide vitavax before storage in aluminum foil or polyethylene bag maintained onion seed germination %, seed and seedling vigor comparing untreated seed stored in cloth bags. This study suggested that, onion seed should be treated by fungicide vitavax before storage in aluminum foil to maintain onion seed quality during storage and get high field emergence.

he study was carried out during the two successive seasons of 2013/14 and 2014/15 at the farm of Sers El-Lyan Agricultural Research Station, Agricultural Research Center, El -Menofiya Governorate, Egypt to study the influence of different ridge widths and patterns of intercropping onion with faba bean on faba bean productivity and its quality. The treatments between three ridge widths (60, 90 and 120 cm) and ten cropping systems (100% faba bean + 27% onion, 100% faba bean + 33% onion, 100% faba bean + 41% onion, 100% faba bean + 55% onion, sole faba bean 'recommended', sole faba bean 'I', sole faba bean 'II', sole onion 'recommended', sole onion 'I' and sole onion 'II') were studied. The experimental layout was conducted in split plot design with three replications by allocating the ridge widths in the mainplots and cropping systems in the sub-plots. Sub-plot area consisted of (12 ridges-60 cm width or 8 ridges-90 cm width and 6 ridges-120 cm apart) and 3 meters long. The results showed that' faba bean at ridges 90 cm had the highest values of number of seeds per pod and plant and pods weights, seed yield per plant , 100 -seed weight and harvest index. Meanwhile' the widest ridge width produced the highest seed and straw yields per fad and seed phosphate content compared to the other ridge widths. Sole faba bean had the highest numbers of branches per plant and pods per plant, number of seeds per pod, plant total weight, pods weight per plant, seed yield per plant, 100 -seed weight, seed yield per fad, protein yield per fad, harvest index and seed phosphate content compared to those of intercropping patterns. Intercropping pattern of 100% faba bean + 27% onion produced the highest numbers of branches and pods per plant, number of seeds per pod, pods weight per plant, seed yield per plant, 100 -seed weight, seed yield per fad and protein yield per fad compared to those of the other intercropping patterns. The interaction between ridge widths and cropping systems was significant for most traits. Intercropping pattern of 100% faba bean + 55% onion of ridge width 120 cm achieved high seed P content and seed yield per fad.

he study was carried out during the two successive seasons of 2013/14 and 2014/15 at the farm of Sers El-Lyan Agricultural Research Station, Agricultural Research Center, El -Menofiya Governorate, Egypt to identify and assess the suitable pattern of intercropping onion with faba bean for increasing land usage and profitability of farmers. The treatments between three ridge widths (60, 90 and 120 cm) and ten cropping systems (100% faba bean + 27% onion, 100% faba bean + 33% onion, 100% faba bean + 41% onion, 100% faba bean + 55% onion, sole faba bean 'recommended', sole faba bean 'I', sole faba bean 'II', sole onion 'recommended', sole onion 'I' and sole onion 'II') were studied. The experimental layout was conducted in split plot design with three replications by allocating the ridge widths in the main-plots and cropping systems in the sub-plots. Sub-plot area consisted of (12 ridges-60 cm width or 8 ridges-90 cm width and 6 ridges-120 cm apart) and 3 meters long. The results showed that' higher bulb diameter was obtained, followed by 90 cm ridge width. On the other hand, the closest ridge width gave the lowest bulb diameter. The highest total weight of the plant, average bulb weight and bulbs yield/fad were obtained under the widest ridge width, followed by 90 cm ridge width. Sole onion had the highest number of leaves per plant, bulbs length and diameter, total weight of the plant, bulb weight and blubs yield per fad compared to those of intercropping patterns. The maximum number of leaves per plant, bulbs length and diameter, total weight of the plant and bulb weight were obtained by intercropping pattern 100% faba bean + 27% onion; Meanwhile' the highest bulbs yield per fad was recorded by intercropping pattern 100% faba bean + 55% onion. The interaction between ridge widths and cropping systems was significant for most onion traits. Maximum relative yield of onion and land equivalent ratio were obtained by intercropping pattern 100% faba bean + 55% onion of ridge width 120 cm. On the other side, maximum relative crowding coefficient (RCC) was obtained by intercropping pattern 100% faba bean + 27% onion of ridge width 120 cm. The results indicate that' the value of aggressivity of faba bean was positive for all treatments, while, the values of aggressivity were negative for all intercropped onion with faba bean in both seasons. Intercropping pattern 100% faba bean + 55% onion of ridge width 120 cm achieved the highest bulbs yield and economic return.

and Giza 136) were evaluated for drought tolerance by measuring yield performance under normal irrigation and water stress conditions. The results indicated that, all the studied characters were significantly affected by stress in both growing seasons, except for total chlorophyll, spike length, no of grains/spike and harvest index, in both seasons. Stress reduced grain yield (ardab/fad.) by reducing the number of spikes/m 2 and 1000-kernel weight. This study showed that, the best genotypes of barley for all parameters studied under stress condition were Giza 133 followed by Giza 134 in both seasons.
