The mulching treatments materials included flat surface mulched with cucumbers residues, flat surface mulched with clear plastic sheets and flat surface mulched with black plastic sheets. The results showed that maximum soil temperature values in ridge treatments, at any given depth were higher than that observed in a flat plot without mulching.

Concerning the mulching materials effect, the black plastic sheets gave the highest values of maximum and minimum soil temperature followed by clear plastic sheets and cucumbers straw mulching.

The soil of the field experiments was sandy loam. The electrical conductivity of irrigation water was 1.1 dSm-1. The treatments were arranged in a split plot design with four replicates. The main plots were assigned with four amounts of irrigation water of daily applied on a base of 100%, 90%, 80% and 70% of ETc with four nitrogen rates i.e. zero, 50, 100 and 150 kg N fed.-1 in the sub plots. The combined analysis over the two growing seasons showed that daily irrigation with applied water equals 100% of ETc increased plant height, ear length, number of grains row-1, 100-grain weight and maize grain yield by 3.33, 7, 15.25, 6.19 and 37.25% as  compared to daily irrigation with applied water equals 70% of ETc. Daily irrigation with applied water equals 100% of ETc, significantly increased N, P and K concentration in Zea maize plants and grains by (36.9, 21.2 and 9.8%) and (23.5, 21.2 and 18.5%) as  compared to daily irrigation with applied water equals 70% of ETc, respectively.

The aim of the study was, to investigate effects of water irrigation salinity and the irrigation intervals on growth, yield and quality of sugar beet crop, cultivated on saline clay soil at El-Hamoul, Kafer El-Sheikh governorate. The experiment comprised planting sugar beet with three irrigation intervals as main plot, namely; two weeks (I1), three weeks (I2) and four weeks (I3). Three irrigation water salinities as sub plot; S1 fresh water (0.5dSm-1), S2 mixed water (1.8dSm-1) and S3 drainage water (3.8dSm-1). Sugar beet (Beta vulgaris L) seeds were planted by hand and irrigated with fresh water (0.5 dSm-1) until sugar beet plants had 6- 8 leaves. Then the plots received different irrigation water with different intervals according to treatments. Results showed that irrigation every 2 weeks with fresh water (treatment I1 S1) produced the highest sugar beet yield and the highest sugar percent, 27.03 ton/fed. and 18.2%, respectively. While irrigation every 4 weeks with drainage water (I3 S3) produced the lowest yield,18.4 ton/fed., and the lowest sugar percent, 13.1 %. Irrigation with drainage water (S3) significantly reduced the beet root yield by about 21% relative to irrigation with fresh water (S1). Also water salinity 3.8dSm-1 significantly reduced beet root yield quality. The lowest beet root quality was obtained with the drainage water.  Increasing irrigation intervals from 2weeks up to 4 weeks, significantly decreased the root yield of sugar beet .The sugar percent of sugar beet, also, slightly decreased but not significantly, with increasing the irrigation interval .It could be concluded that irrigation at short intervals could compensate, partially, the hazard effect of the water salinity on the crop yield. Under the condition of the present study ,  irrigation every 2 weeks with water salinity up to 3.8 dSm-1,had an acceptable sugar beet root yield (22.1 ton roots/fed) of satisfactory quality(2.89 ton sugar/fed). The productivity of irrigation water (PIW) for both of root and sugar yields decreased with increasing salinity of irrigation water, but this decrease was lower for sugar yield than root yield. Increasing the irrigation intervals from 2 weeks to 4 weaks increased the (PIW) of root yield from 7, 28 to 8.8 kg/m-3, and that of the sugar yield from 1.12 to 1.51 kg/m-3. On the light of this study, it could be recommend the possibility of irrigating  sugar beet with drainage water (S3), at 2 or 3 weeks intervals, to obtain economical yield with satisfactory quality.  }, keywords = {Sugar beet, irrigation interval,salinity of irrigation water}, url = {https://jssae.journals.ekb.eg/article_75189.html}, eprint = {https://jssae.journals.ekb.eg/article_75189_c67057b3cb7a5bcf51925ff3120e552b.pdf} } @article { author = {Eid, S and El-Atawy, Gh and EL-Shreif, M}, title = {YIELD AND SOME WATER RELATION OF MAIZE CROP AS INFLUENCED BY IRRIGATION SCHEDULING AND NITROGEN FERTILIZATION RATES AT MIDDLE NORTH NILE DELTA}, journal = {Journal of Soil Sciences and Agricultural Engineering}, volume = {1}, number = {8}, pages = {801-813}, year = {2010}, publisher = {Mansoura University, Faculty of Agriculture}, issn = {2090-3685}, eissn = {2090-3766}, doi = {10.21608/jssae.2010.75198}, abstract = {Two field experiments were conducted at Sakha Agricultural Research Station, Kafr El-Sheikh Governorate, Egypt during the two successive seasons of 2007 and 2008.

Soil chemical properties; and soil productivity for wheat plants (Triticm aestivum L) Giza 168 were also observed. Data obtained from water samples of all wells show that, the pH values of irrigation water were in the normal range, the values of EC were ranged from 0.93 to 1.99 dSm-1, the values of total dissolved solid (TDS mgl-1) were ranged between 595.2 to 1273.6 mgl-1, and the cation values for water wells were found in the following order: Na > Ca > Mg than K. While anions were: Cl > SO4 more than HCO3. Meanwhile, the data obtained from soil samples show that, the soil texture was generally sandy loam, soil reaction is generally slightly to moderately alkaline, gypsum content were ranged from 0.80 to 6.43%, soil organic matter ranged between 0.14 to 0.93%, cation exchange capacity was ranged between 3.08 to 17.62 meq/100g soil, and the soluble cations are in the following order: Na > Ca > Mg than K., while soluble anions were Cl > SO4 more than HCO3. Finally, soils in Toshka area were very poor in there contents of available macro and micro nutrients; therefore, the productivity of wheat plants were recorded 10.75 ardab fad-1. Also, data revealed that the macro and micronutrients in wheat grains, straw and roots recorded lower values compared with the normal values.}, keywords = {Toshka area,water quality,soil properties and wheat productivity}, url = {https://jssae.journals.ekb.eg/article_75302.html}, eprint = {https://jssae.journals.ekb.eg/article_75302_d95862be00d0294c1c71669f85145a0d.pdf} } @article { author = {Abou El-Magd, A and Elbanna, E and Ismail, Z}, title = {DEVELOPMENT PLANTING AND HARVESTING SUGAR BEET CROP MACHINE.}, journal = {Journal of Soil Sciences and Agricultural Engineering}, volume = {1}, number = {8}, pages = {895-919}, year = {2010}, publisher = {Mansoura University, Faculty of Agriculture}, issn = {2090-3685}, eissn = {2090-3766}, doi = {10.21608/jssae.2010.75308}, abstract = {The main goal of the present research is to develop a rationalized power, and operation cost combined machine suitable for sugar beet planting and harvesting operations, and to be suitable for the Egyptian agricultural conditions. The developing machine components can be summarized in two parts: First component is planting unit: is planted two sugar seeds' rows with suitable depth at top of the middle center of the two row furrows, in the same time formed three cultivable rows. The formed three shares are seated after the two planting rows. Each formed row share is a consisted from a double mouldboard bottoms, at end of it whereas, the drop seeds is covered by the sliding soils path. Second Component is sugar beet pulling unit: is involved three main sugar beet harvester components namely, two appropriate shares for loosing the ridge structure around the roots, pulling out belt mechanism with its proper power transmission system, and a proper disk knife as a topping mechanism. The machine id performed 60-70 cm riders during planting two rows. Also harvester one sugar beet row through pulling out and topping mechanisms. Three proper  ridges in shape of a double mouldboard were constructed one was fixed on the front  machine frame and the other two ridges were fixed on the back frame. Also two proper shares form for loosing the ridge structure around the roots.}, keywords = {}, url = {https://jssae.journals.ekb.eg/article_75308.html}, eprint = {https://jssae.journals.ekb.eg/article_75308_de89ed13cead185e78cc32f4cfa40bf8.pdf} }
