FIELD experiment was conducted at Sakha Agric. Res. Station, Kafer EL-Sheikh Governorate, Egypt during 2013/2014 and 2014/2015 seasons to study the relative advantage of intercropping faba bean (variety Giza 643) with sugar beet (variety Geloria) and its impact on yield and quality attributes of both crops. A split plot design with three replications was used. The treatments of faba bean sowing distance (10, 20 and 30 cm) allocated in the main plots, while, the ten combination of nitrogen levels with bio fertilizers (90, 72, 54, 36 kg N/fad, 72, 54, 36 kg N/fad + Cerealine, 72, 54, 36 kg N/fad + Rizobacterine) were arranged in sub plots, the obtained results showed that:

Field experiments were conducted at Rice Research and Training Center, Sakha, Kafrelseikh Governorate, Egypt during two summer seasons 2010 and 2011 to study the influence of integration between compost and urea fertilizer on yield and its components of Sakha 105 rice cultivar as well as nitrogen uptake in rice grains and soil organic matter percentage. The treatments were (0, 5 ton compost/ ha, 165 kg N/ha, 5 ton compost + 55 kg N/ha and 5 ton compost + 110 kg N/ha). The results revealed that compost and mineral nitrogen (urea) alone or in combination recorded increasing significant values in number of panicles/hill, number of filled grain/panicle, 1000 grain weight, grain and straw yields, nitrogen uptake and soil organic matter percentage compared with the control treatment (without fertilization) except the number of unfilled grain/panicle which recorded significantly decrease. The results, also, showed that compost application at rate of 5 tons plus 110 kg N/ha gave the highest values of number of panicle/hill, number of filled grains/panicle, 1000 grain weight, grain yield, straw yield, nitrogen uptake in grains and soil organic matter percentage in both seasons. The control treatments (without fertilization) recorded the lowest values in all traits as well as yield components, grain yield, straw yield, nitrogen uptake in grain and soil organic matter percentage except the number of unfilled grain/panicle which recorded the highest values in both seasons. In both seasons the following treatments of 165 kg N/ha, 5 ton compost plus 55 kg N/ha and 5 ton compost plus 110 kg N/ha didn't significantly differ in its effect on the number of filled grains/panicle. In both compost application at a rate f 5 tons alone or in combination with 110 kg N/ha gave the same 1000 grain weight without significantly differences with 165 Kg N/ha treatment in the second seasons. The percentage of soil organic matter was increased with addition of compost either alone or with different levels of nitrogen which did not significantly differed in its effect on the percentage of soil organic matter. From the results under the conditions of this study, it could be concluded that application of 5 tons compost plus 110 kg N/ha produced the highest grain and straw yields and is recommended as an economic treatment for increasing grain yield of rice.

and 2011 seasons, to study the effect of mineral and organic nitrogen fertilizers on rice productivity reedu traditional transplanting and transplanting in bottom of beds metsdeh and so on water saving and its use effeciency under the conditions of Kafrelsheikh Governorate for rice cultivar Sakha 105. Fertilizer treatments were as following (160 kg N/ha, 120 kg N/+ 5 tons compost/ ha and 80 kg N + 5 tons compost/ ha). Treatments were arranged in split plot design with four replicates. The main plots included the two planting methods, while, the three fertilizer treatments were allocated at the sub plots. The obtained results could be summarized as follows: The results reveal that the method of planting in bottom of beds led to significantly increased in dry weight at heading, 1000 grain weight, grain yield and harvest index in both seasons as well as number of grains/panicle in the second season compared with the method of traditional transplanting, which recorded a highly significant values in plant height, number of panicles/hill in both seasons and straw yield in the second season. Data show that planting in bottom of beds led to significant increase in water use efficiency and achieved water saving of 4798 and 4788 m 3 /ha (2016 and 2012 m 3/ fed.) in the first and second seasons, respectively as compared with traditional transplanting method. The obtained results show that application of mineral nitrogen 120 kg N in combined with 5 tons compost/ha significantly recorded the highest values of plant height number of panicles/hill, number of grains/panicle, 1000 grain weight, grain and straw yields and harvest index in both seasons as well as dry weight only in the first season. The treatment of 160 kg N/ha didn't significantly differed with the treatment of 120 kg N + 5 tons compost/ha in 1000 grain weight in the first season, grain yield in the second season and harvest index in both seasons. From the obtained results under these conditions of this study, it could be concluded that planting rice in bottom of beds saved water in average of 4793 m 3 /ha and increased water use efficiency as compared with traditional transplanting. Also, application of 5 tons compost plus 120 kg N/ha gave the highest productivity of rice cultivar Sakha 105 Kafrelsheikh.
