A Field experiment was carried out on broccoli (Broccoli oleraceae L. var. Italica cv. Red acare), Brassicaceae family, in Faculty of Agriculture, El-Mansoura University, Egypt during 2010 season to study the effect of both farmyard manure and Agrisbone (Commercial fertilizer) as biofertilizer source and N fertilizer rates on vegetative growth, yield and flower spear quality of broccoli plants grown on alluvial soils. Treatments were represented all combination of FYM rates (control and 20 m3 fad-1) and N fertilizer rates (control, 50,100 and 150 kg fad-1 as ammonium sulphate, (20.5 % N) in presence of Agrisbone (with and without addition) in split split plot design with three replicates.
The obtained results could be summarized as follows:
- Statistical analysis revealed that the highest mean values of leaves number, and branches number of broccoli plants were obtained from 150 kg fad-1 mineral treatment jointly with inoculated plants in absence of FYM, while the highest mean values of fresh and dry weight were produced from the inoculated plants with 100 N kg fad-1 under FYM treatment. On the other hand, the lowest mean values of aforementioned characteristics obtained from untreated broccoli plants.
- Data indicated that the maximum mean values of height and diameter spear flower produced from plants received FYM and Agrispone combined with 100 N kgfad-1 as compared to the other treatments.
- The broccoli plants that fertilized with FYM + Agrispone + 100 N kgfad-1 gave the highest increments in the two stages of spear flower broccoli yield; 1st and 2nd cuts. Meanwhile, unfertilized broccoli plants gave the lowest mean values of aforementioned traits in the two stages; 1st and 2nd cuts, respectively.

There is an inability in facilitating phosphorus under Egyptian soil conditions. For this purpose, a pot experiment was conducted at the experimental farm Faculty of Agric., El-MansouraUniv. during the winter season of 2008-2009 to investigate the uptake of applied and residual phosphorus by wheat (Triticum aestivum L.) plants as affected by mycorrhizal inoculation under saline condition. Phosphorus was applied at four rates of 0, 50, 75 and 100 Kg/feddan as single super phosphate (15.5%P2O5) under three levels of salinity (1, 6 and 9 dSm-1). Arbuscular mycorrhizal (AM) fungi was used as a mixture including (Glomus mossea, Glomus intraradices and Glomus clarium). The results of this investigation revealed that;with AMinoculation, the mean values of N, P and K% in shoot and roots and Na% in roots were significantly increased. Also, with AM inoculation, the mean value of Na% in shoots decreased. This trend was true during both stages of planting. On contrast, in non- mycorrhizal inoculated plants the illustrated average of N, P and K% in wheat shoot and roots were significantly decreased as the level of salinity increased. On the other hand, the mean values of Na % in wheat shoots and roots were significantly increased due to adding salinity levels over the control during both stage of growth. Concerning the effect of phosphorus application, the average of N, P and K% in wheat shoots and roots were increased significantly over the control. Adding P3 level was superior for increasing aforementioned traits. Addition of P levels, however, had no significant effect on Na% in wheat shoots. This trend was observed during both stages of the experiments. With respect to the interactive effect between adding AM, salinity levels and phosphorus application, it could be realized that adding P3 level with S0 level combined with I1 (AM inoculation) gave the highest value of N, P and K in wheat shoots and roots. However, the mean values of Na % did not significantly affected by treatments of the experiment.

Two field experiments were conducted at Sakha Agricultural Research Station farm, Kafr Elshiekh Governorate during the two successive seasons 2005 and 2006 to study the effect of intermittent irrigation water and nitrogen fertilizer levels on rice yield and water requirements. The experiments were arranged in split plot design with four replicates where the intermittent irrigation treatments represent the main plots; (I1) soil saturation along the growing season, (I2) soil submergence with 2.5 cm depth in first half of growing season, then irrigation at soil saturation in the second half of the growing season, (I3) soil submergence with 2.5 cm depth along growing season, (I4) soil submergence with 5 cm depth in the first half of season, then irrigation at saturation in the second half of the growing season and (I5) soil submergence with 5 cm depth along the growing season. In this concern nitrogen fertilizer levels represent the sub main plots; where N1,N2, N3 and N4 were the application of nitrogen at 50%, 75%, 100% and 150% from the recommended dose, respectively.
The maximum rice yields of both grain and straw and its components were obtained with irrigation water depth of 5 cm.( I5 ) and nitrogen fertilizer of N4 ( 69 kg N/fed ) as well as their interaction. This was true for both growing seasons. The highest 1000- grain weight, and panicle length were recorded with above mentioned treatment, while the lowest values, were recorded with irrigation at saturation treatment ( I1) and nitrogen rate of 23 kg N/fed (N1) in both growing seasons. The highest amount of water applied for permanent field was recorded with 5 cm irrigation water depth along the season, in the two growing seasons, while the lowest value was recorded with irrigation at saturation treatment. The highest mean value of crop water use efficiency (CWUE)was recorded at 5 cm submergence depth along the season (I5), while the lowest mean value was obtained at saturation treatments along growing seasons (I1). The values of field water use efficiency (FWUE) had the opposite trend of (CWUE ).

Apot experiment was carried out in the farm of Fac. of Agric. Mansoura University during the winter cultivation of 2010 and 2011 to investigate the impact of minimizing levels effect of salinity for spinach plant (SpinaciaOleracea) by using some organic materials.
Thirty treatments were arranged in split-split block design, which three treatments of salinity levels, S1 (2.55), S2 (4.79), and S3 (6.39) ds /m in 1:5 soil water extraction were assigned to the main plots. Five treatments of organic materials, i.e; farmyard manure (F.Y.M.), chicken manure (Ch.M.),compost of rice straw, wood saw dust (W.S.) and the untreated treatments (control)were allocated in the sub-plots. Each treatment was investigatedtwice; one was sprayed with ascorbic acid and the other without spraying it and arranged in sub-sub plots. Thus, the total numbers of pots were 90 pots.
The results of this investigation revealed that; with increasing salinity levels, the mean values of fresh and dry weights (g) of spinach plant leaves,rootsand the mean values of N, P&K uptake (mg/plant) of spinach plant leaves and roots.AlsoCa, Mg & Na uptakes (mg/plant) ofroots were decreased. On the other hand, the mean values of Ca, Mg and Na uptakes (mg/plant) of spinachleaves were increased with increasing salinity levels.
Data also indicated that under addition of organic materials, all parameters under investigation were significantly increased.The highest mean values of fresh and dry weights (g) of spinach leaves and roots and the highest mean values of N, P &K uptakes (mg/plant) of spinach foliage and roots were recorded with adding chicken manure, however the highest mean values of Ca, Mg and Na uptakes (mg/plant) of spinach foliage and roots were realized with adding wood saw dust.
Concerning the effect of ascorbic acid as foliar application at rate of 400 ppm, it wasfound that all parameters under investigation significantly increased except the mean values Ca, Mg & Na uptakes (mg/plant) of spinach rootswhich were significantly decreased.

This laboratory experiment was carried out to study the individual and combined effect of two organic acids (humic and oxalic acids) and salinity levels of irrigation water on the changes of chemical properties and the content of available phosphorus of two calcareous soils of Egypt. The soils were treated by either humic or oxalic acid at application rates of 0, 0.1, 0,2 and 0.4% and irrigated by one of irrigation water resources varied in their salinity levels at 100% of soil field capacity. The used three water resources were tap water (W1), sea water (W3) and mixed water between W1 and W3 with mixed ratio of 1:1 (W2). This experiment was carried out in plastic pots, where it arranged in completely block randomized system with three replicates. These pots were incubated at room temperature (25 ± 2 ◦C)for 6 months. After that, soil pH, EC (dSm-1), CEC (meq/100g), total and active CaCO3 (%) and the content of available P (mg/kg) were determined.
Organic acids applications resulted in a decrease of soil pH and its content of total CaCO3 % and increased soil EC (dSm-1), CEC (meq/100g), and the content of active CaCO3 (%) and available P (mg/kg). On the other hand, increasing salinity levels of irrigation water resulted in a decrease of soil content of total CaCO3 and increased soil pH, EC, CEC, active CaCO3 and available P. The relative changes (RC, %) of the studied soil properties were varied widely from soil to anther depending on type and application rate of the used organic acids and salinity level of irrigation water.
