“…Increasing nitrogen application rates at all irrigation treatments significantly increased N accumulation in grain or straw of wheat plant. Similar results were found by Abdel Magid et al (1995) for wheat, Phillips et al (2002) for bean, Clark et al (1999) Colla et al (2002 for tomato, Mahdy (2009) for maize, and Fathi and Shama(2010) for maize. The values of NUE for the straw yield were much greater than those of grain yield at the same irrigation treatment for first season.…”

Field experiments were conducted to investigate the interactive effects between different irrigation treatments and N application rates on grain and straw yields of wheat plants grown on a clay soil and to describe the relationships between irrigation treatments and yield of wheat plants at different N treatments. The factors were nitrogen fertilizer(N): 0(N0), 75(N1), 150(N2), and 225(N3) kg.ha-1 as urea and four treatments of irrigation(I): fully-irrigation with canal water(I1), 2 times well water + canal water (I2), 4 times well water + canal water(I3), and 6 times well water + canal water(I4). The obtained results indicated that grain and straw yields were significantly increased with increasing application rate of N fertilizer at all treatments of irrigation. On the other hand, grain and straw yields of wheat plants were decreased significantly with increasing number of well water irrigation times. The maximum nitrogen use efficiency (NUE) for grain yield (63.73 kg kg-1 N) was found with a 75 kg N ha-1 and I1(fully-irrigation with canal water). In contrast, the minimum NUE for grain yield (19.56 kg kg-1 N) was found with a 225kg Nha-1 and I4 (6 times well water,4500 m 3 ha-1 + canal water, 1500 m 3 ha-1)for first season. Similarly, irrigation with well water decreased the agronomic efficiency (AE) for grain yield noticeably at all N application rates. The reduction in AE for grain yield of wheat was much higher at I4 treatment than of that at I2 treatment. The mean agronomic efficiency (AE) for grain yield for the second season confirmed the results of first season and was very close to each other. Future research works should be made by further developing more efficient wheat varieties that could use N more efficiently at lower rates (<225 kg N ha −1). It can be concluded that the limited amount of available fresh water should be applied during the initial growth stage and supplemented with well water at later growth stages of wheat plants.

“…The statistical analysis indicated that organic manure treatments produced high significantly effects on the average means of dry weight of wheat at 30, 60 and 90 days after sowing in both seasons. This trend agrees with the findings of Abdel-Magid et al (1995), who indicated that the application of organic manure increased the dry weight of wheat by increasing rate of organic manure additions.…”

It is well known that large percentages of nitrogen in the form of nitrate anions leach through soil especially when excessive amounts are applied to soil.Plant intake of nitrate is not fast enough to recover all the excessive amounts of nitrates from plants root zone. The relative slow utilization of nitrate by plants allow losses of nitrates by leaching out the root zone. On the other hand, ammonium cation is adsorbed by soil colloids, so it does not leach out of soil . Nitrification of NH + 4 to NO -3 in soil is also a source for nitrate .The aim of the present investigation was to look for how to reduce this risk and at the same time increase the economic reflect of the nitrogen unit in the soil by using organic manure treatment (town refuses [TR] , farmyard manure [FYM]), and biofertilizer (Nitrobin).Two pot experiments were conducted during the successive growing seasons of 1996/97 and 1997/98 at El-Serw Agriculture Station -Damietta. Each pot was filled with 15 kg of a sandy soil obtained from El-Rakabia.The experiment were designed as split-split plot , two treatments of microbial inoculation (I0 and I1) assigned the main plots. Five forms and levels of organic manure treatments (Control, 5g FYM, 10g FYM, 5g TR and 10g TR / kg soil) occupied the sub-plots, while, the nitrogen fertilizer levels (N0, N20, N40, and N80 mg N / kg soil) occupied the sub-sub plots . The total number of this trial were 40 treatments. Each treatment was replicated five times, hence 200 containers were conducted.The obtained results could be summarized as follows:-Biofertilization of wheat grains by Nitroben and organic manure additions caused significant increases in the mean values of wheat dry weight (g/plant) during both seasons. Significant decreases in leached NO -3 and NH + 4-N in drainage water were recorded due to biofertilization and manure application. Nitrogen uptake high significantly increased due to both Nitrobin inoculation and manure treatments. The highest means of utilization rate (UR) of applied nitrogen were produced due to organic manure additions. Increasing the applied-N fertilizer tended to reduce the N-utilized percent.The obtained results illustrate the beneficial effects of bio and organic fertilization on reducing the adverse environmental impacts of inorganic nitrogen in agro-ecosystem.

The current prices of microalgae oils are much higher than oils from higher plants (vegetable oils) mainly due to the high cost of photoautotrophic cultivation of microalgae. However, many strains of microalgae can also grow and produce oil using organic carbons, as the carbon source under dark (heterotrophy) or light conditions (mixotrophy). Lipid productivities of most strains of microalgae are higher in culture systems that incorporate heterotrophic metabolisms (presence of organic carbon source) than under photoautotrophic conditions. This is because for many strains, cell growth rates and final cell concentrations are higher in heterotrophic cultures than in photoautotrophic cultures. Furthermore, in some cases, the oil contents of the cells are also higher in cultures incorporating heterotrophic metabolisms. It has also been reported for some strains that the quality of oil produced in the presence of organic carbon sources are more suitable for biodiesel oil production than those produced under photoautotrophic conditions. Thus, heterotrophy can be used to reduce the cost of biodiesel oil production, but the effectiveness of the various organic carbons in supporting cell growth and oil accumulation depends on the strain and other culture conditions. Use of wastewaters for cultivation of microalgae can further substantially reduce the cost of production (since they contain carbon, nitrogen, and other nutrients) and also reduce the requirement for freshwater. Generally, many factors such as nitrogen limitation, phosphate limitation, silicon limitation, control of pH, and low temperature can be used to increase oil accumulation, although their effectiveness depends on the strain and other culture conditions.
