Two field experiments were conducted during winter seasons of 2014/2015 and 2015/2016at Sahl El-Hossinia Agric. Res. Station, El-Sharkia -Governorate, Egypt to evaluate the effect of humic acid, compost tea and bio-fertilizer using two methods of application (foliar and soaking) on some chemical and physical soil properties and Egyptian clover (TrifoliumalexandrinumL.) var. Meskawy productivity under saline soil conditions. The soil pH and EC values decreased due to different treatments using soaking or foliar application.The lowest value of EC in soil reached (4.61 dSm -1 )by applying humic acid as foliar application.The soil content of O.M increased in caseof bio-fertilizer, humic acid and compost tea compared with control using soaking or foliar application, however, a high increase was attained by humic acid foliar application.The CEC (cmolkg -1 ) valuewas affected by different fertilizer sources using soaking or foliar application. The high mean value of CEC was 41.42cmolkg -1 in case of humic acid foliar application compared with other treatments and control. The highest values of field capacity and available water were found in case of humic acid foliar application compared to other treatments and control using soaking or foliar application. The values of soil bulk density of soil profiles treated by all treatments were relatively low compared to those of control, whereas the maximum decrease exists in soil treated byhumic acid foliar application compared to other treatments and control using soaking or foliar application. Adding humic acid as foliar application increased the soil total porosity values compared to other treatments and control. Data showed that the values of drainable pores (DP) and water holding pores (WHP) were higher than the other pores in different treatments. The highest diameters of dry aggregates were affected by humic acid foliar application compared to other treatments and control. The high values of total stable aggregates were observed incase of humic acid foliar application. Applying bio-fertilizer; humic acid and compost tea on seeds using soaking or foliar application increases significantly the clover yield and yield components except the interaction between treatments and methods of application. Humic acid with foliar application gave the highest values of Egyptian clover yield and yield components as compared by other treatments. The obtained data indicate that the Egyptian clover yield was clearly affected by all treatments under saline soil conditions. The beneficial effects of all treatments compared with control using soaking or foliar application on Egyptian clover yield could be arranged as follows according to the increases in dry yield (ton/fed)of clover: Humic acid > compost tea> Bio-fertilizer > control, for soaked application and humic acid > Bio-fertilizer > compost tea > control, for foliar application.

he hydroponic under Egyptian condition take more attention in the last decade. The experiment was conducted under net house in intensive hydroponic system and replicated three times during January and February 2017. The study was done to evaluate vegetative characteristics and quality properties of produced sprouting of six barley cultivars (Giza123,126,127,128,129 and130). The results observed that the sprouting can be produce in 8 days from planting to harvest using hydroponic technique under the net house conditions. The Highest green barley fodder was recorded with Giza 127 followed by 129 which gave 6.98, 6.83 Kg, respectively compared with other strain. The results indicated that the highest value of fresh sprout: seeds weight ratio was recorded significantly by Giza 127 followed by Giza 129 compared to the other four cultivars. The crude protein values in several green fodder barley species significant (P<0.05) increase (the range from 11.56 to 13.45%) compared with its grains (the range from 9.58 to 12.60%). The highest values CP% in green fodder barley recorded with (Giza 127) was (13.45% on DM basis). There were a significantly (P<0.05) increase for CF% between green fodder barley species (the range from 9.93 to 14.36) in 8-days sprouting compared with the several original barley grains (the range from 5.67 to 8.85%). Also, the EE were significant increased except (Giza 129 and Giza 130) were decreased. The highest significant values NDF was recorded (37.47%) with (Giza 123) compared several cultivator Green fodder barley species, but ADF was recorded (17.93) with (Giza 127). The highest significant values ADF and acid insoluble ash were recorded (5.91 and 1.78) with (Giza 130) compared several cultivator Green fodder barley species. The highest significant values hemicellulose was recorded (20.85%) with (Giza 123), celluloses was recorded (12.63%) with (Giza 126) compared several cultivator Green fodder barley species. however, significant increased NDF-cell soluble was recorded (80.88) with (Giza 130). The parameters of nutritive values are predication from chemical composition observed significant increase of DCP between seed barley and several cultivator Green fodder barleys except Giza (129) and (130). The highest result values of DCP cultivator Green fodder barley was recorded with (Giza127) the value increase from7.67% in seed to 8.44%in sprouting. The DDM and DMI were significantly decrease in all several cultivator Green fodder barleys compared with seed barley. Also, several cultivator Green fodder barley productions observed significantly decreased of TDN in all strains compared with its seeds. The parameters of energy values are predication from chemical composition of Egyptian barley for seed (

To investigate the effect of sowing dates and potassium fertilizer rates on seeds yield and yield component of lima bean. Two field experiments were conducted at Sakha Agricultural Research Station during 2015 and 2016 summer seasons. Four sowing dates (1 st May, 15 th May, 30 th May and 15 th June) and potassium fertilizer rates (0, 50, 75, and 100 kg/fed) were used as treatments. The main findings could be summarized as follows:Sowing dates significantly affected seed yield (t/fed), No. of seeds/pod, pod length (cm), No. of pods/plant, pods weight/plant, plant height (cm), stem diameter (cm), No. of branches/plant. Sowing on 1 st May significantly exceeded all studied traits compared with other sowing dates and produced the highest yield (2.477 t/fed), while the lowest sowing date on 15 th June. The stem diameter increased with sowing late (1.810 t/fed.).Potassium fertilizer rates significantly affected on seed yield (t/fed), No. of seeds/pod, pod length (cm) , No. of pods/plant, pods weight (t/ fed), plant height (cm), stem diameter (cm), No. of branches/ plant. The results indicated that the highest lima bean seed yield was 2.375 (t/fed) when fertilized with100kg k 2 o/fed and the lowest at control zero fertilizer 1.990 (t/fed).It could be concluded that early sowing on 1 st May with addition potassium fertilizer rate at 100 kg k 2 o/fed were the recommended treatment to produce the highest seed yield production of lima bean at North Delta under the environmental condition of Kafr EL-Sheikh Governorate.

This work was performed at Sahl El-Hossinia Agric. Res. Station, El-Sharkia, Governorate, throughout winter seasons of the year 2016/2017 and 2017/2018 to investigate the foliar application of compost tea humic acid, and bio-fertilizer on forage production, seeds, chemical analysis of plant and soil. Using bio-fertilizer; humic and compost tea on plant increases significantly the clover yield. Humic acid recorded that increased of values for yield, yield components and quality as compared by other treatments. Results pointed that forage yield was affected by whole treatments under saline soil conditions. In general, berseem clover treated with humic acid increased the plant height, fresh, dry yield, seeds yield, weight of 1000 seeds, crude protein, fiber fraction, Total carbohydrate, digestible crude protein of forage yield as compared with control. Values of EC and pH of soil were decline due to various traits using foliar application, while the highest rate of EC in soil run to (5.72 dsm-1) at bio-fertilizer. Values of soil properties treated by whole traits were slightly low comparing control (7.72 dsm-1). It is clear that the minimum total costs were those of application of Bio-fertilizer, being 4570 L.E and the maximum total costs were those of the plants received Compost-t rate which was 5180 L.E. Average over all treatments of total costs were 4847.5 L.E for the two season. The highest value of net return per one invested L.E was achieved when using humic acid (5.40 L.E) and Compost-t (4.15 L.E) compared with N fertilization (control 2.63 L.E).

Two field experiments were carried out at Bahr Hadous drain and El-Salam canal locations in Sahl El-Hossinia , El-Sharkia -Governorate, Egypt, for winter seasons of 2014/2015 and 2015/2016, to study the effect of humic acid application on some physical and chemical soil properties and fodder beet (Beta vulgaris L.) productivity and quality in saline soil conditions irrigated with different water sources i.e. [Bahr Hadoos drainage water and Nile water from El-Salam canal mixed with agricultural drainage (1:1)].The obtained results show a noticeable reduction in soil pH and salinity as a result of treating the soil with humic acid compared to control. The effect is more obvious in case of applying humic acid high rate of (2400 ml/400 L water,T 4 ) irrigated with El-Salam canal water than Baher Hados drain water .The soil O.M content and cation exchange capacity values were improved by applying humic acid high rate where soil OM content reached 0.80 and 0.73 % in case of using El-Salam canal and Baher Hados drain water compared with 0.63 and 0.55 % for control treatment, respectively. The highest diameter of dry aggregates was affected by the application of humic acid high rate with El-Salam canal water than Baher Hados drain water .Moreover, the maximum values of total stable aggregates were obtained in case ofhumic acid high rate using El-Salam canal water compared to Baher Hados drain water and control treatments. The data also show that the values of hydraulic conductivity were lowand increased by humic acid application. The highest value of hydraulic conductivity was obtained in case of applying humic acid high rate using El-Salam canal water than Baher Hados drain watercompared to control treatment. Applying humic acid high rate decreased the soil bulk density and increased total soil porosity valuesusingEl-Salam canal water as compared to Baher Hados drain water and control treatments. The maximum values of field capacity and available water were recordedin case of applying humic acid high rate using El-Salam canal than Baher Hados drain water compared to control. The result show an increase in fodder beet yield in all treatments compared to control and was higher in the case of humic acid high rate with El-Salam canal than Baher Hados drain water. Generally, the study recommends using humic acid (2400 ml/400 L water,T 4 ) with El-Salam canal or Baher Hados drain which improves soil chemical and physical properties and thus increases the productivity of saline soil.
