Stapf plant during two summer years of 2011 and 2012 at a private Farm located in New-Domiata, Domiate Governorate, to study the effect of three irrigation intervals (3, 6 and 12 days) and two foliar applications with Super Bluegreen and / or Super Cetrin at (75, 100 and 150 ppm) on yield and essential oil production and composition of lemongrass.
The physical and chemical properties of the oil were determined and are included in this study. G.L.C. separation of the essential oil revealed 6 identified compounds (myrcene – limonene – linalool - neral (citral b) - geranial (citral a) and genaryl acetate). Generally the main components of lemongrass oil was neral (citral b) and geranial (citral a) which achieved the largest values.
<strong>The obtained results showed that:</strong>
- Irrigation intervals every 3days increased herb yield /plant and /fed.
- Irrigation intervals every 12 days increased essential oil % and oil yield per plant and per fed, in addition to the main components (citral) in lemongrass leaves.
- Foliar spraying with Super Cetrin gave the highest values of all characters compared to Super Bluegreen in both years.
- The grass yield and essential oil % and oil yield/plant and /fed were higher in the first cut (1<sup>st</sup> July) than to the second cut (1<sup>st</sup> October) during the two years especially in the second year.
- Herb fresh and dry weights / plant, dry yield / fed as well as essential oil % and oil yield per plant and per fed and the main components (citral) percentage were significantly increased by the mixture of foliar application (Super Bluegreen + Super Cetrin) at 100 ppm in both years.
Therefore, it could be recommended that irrigation intervals every 12 days and foliar application with the mixture of Super Bluegreen + Super Cetrin at the rate of 100 ppm maximize the lemongrass essential oil yield and citral content.Mansoura University, Faculty of AgricultureJournal of Plant Production2090-36695920140901USING STATISTICAL METHODS TO EVALUATE SOME INBRED LINES OF MAIZE UNDER DIFFERENT SOWING DATE152315326467910.21608/jpp.2014.64679ENHoda E.

Egypt.Journal Article20191211GGE biplot analysis is an effective method which is based on the principal component analysis (PCA) in order to fully evaluate multi environmental yield trials (METs). Additive main effects and multiplicative interaction (AMMI) is an alternative method for assessing phenotypic stability and adaptability. In this research, data of 16 maize inbred lines were used to perform AMMI and GGE biplot analysis. These inbred lines were evaluated under four sowing dates during two successive summer seasons of 2012 and 2013. Inbred line by sowing dates table was used for performing the analysis. Based on both mean grain yield and yield stability, inbred lines Giza 603, Sids 34, Giza 629 and Giza 628 proved to be superior and also had greater mean performance among the test inbred lines. Graphic analysis was used to identify the most suitable inbred lines for each tested sowing date. Inbred lines Sids 34, Giza 629, Gemmeiza 1021, Sids 7, Giza 612, Giza 628, Giza 603, Gemmeiza 1004 and Giza 602 were identified as suitable in all sowing dates. The AMMI analysis identified the best sowing date as second sowing date D2 which had the highest PCA1 and the best 1PCA2 values. The GGE biplot graphics revealed four sowing dates were clustered into two groups in all cases Group one included sowing date 1 and 2 Group two included sowing date 3 and 4, inbred line Giza 603the best performer in all inbred lines, followed by Sids 34, Giza 629 and Giza 628.
Inbred lines Giza 603, Sids 34, Giza 628, had the highest yield stability into the best sowing dates. Thus sowing date 1 and 4 are the most discriminative sowing dates. .

Super Strain B). It also investigates the effects of using the foliar application of chitosan nanoparticles applied at 0.5 and 1% versus the commercial chitosan applied at the same rates on the growth parameters and the yield of tomatoes and whether these treatments could be positively/negatively affected by treating the plastic tunnels with ZnO nanoparticles. Results revealed that the tomato plants grown under nano-composite covering (PE with nano-ZnO) gave rise to vigor growth, higher yield and fruit quality compared with the tomato plants under low plastic tunnel (PE without nano-ZnO). Chitosan nanoparticles (0.5 or 1 %) increased the plant growth (plant height, fresh, dry weight and leave area), early and total yield per plant and per feddan and average fruit weight beside of improving the quality of fruits (vitamin C, acidity and total sugars) than all other treatments. Thus, using chitosan nano particles (0.5 or 1 %) under nano-composite covering (PE with nano-ZnO) is the recommended practice to attain good growth parameters and achieve early and high total yield with better quality of tomato fruits. However, the low concentration of chitosan nano-particles achieves the highest return economist in this case.Mansoura University, Faculty of AgricultureJournal of Plant Production2090-36695920140901EFFECT OF PLANTING DATE AND SULPHUR FERTILIZER ON YIELD AND QUALITY OF SUGAR BEET UNDER NEWLY RECLAIMED SOILS154715566468110.21608/jpp.2014.64681ENSahar F.TawficSugar Crop Res.

Thus, combining ability for grain yield and agronomic traits was studied in a line x tester crossing program. Thirty six testcrosses produced by crossing (18 inbred lines x 2 testers) along with two commercial check hybrids <em>i.e</em>. SC 10 and SC 128 were grown in replicated yield trail using randomized complete block design with 4 replications in 2011 at two locations, <em>i.e.</em> Sakha and Sids Research Stations. Data were recorded for days to 50% silking, plant and ear heights, number of ears per plant and grain yield (ard./fed.). Mean squares of entries and entries x locations exhibited highly significant to indicate that the two locations differed between them as soon as mean squares due to lines and testers were highly significant for all studied traits, indicating the presence of wide diversity among inbred lines and among testers for these traits. The best performance and desirable GCA effects were recorded for L4 for grain yield and silking date , L14 and L18 for plant and ear heights and L3, L4 and L5 for number of ears / plant. Based on mean performance of F<sub>1</sub> crosses <em>per se,</em> cross L4 x T2 significantly out yielded the check hybrids SC 10 and SC 128. Significant positive SCA effects were found for the same single cross. The additive type of gene action played an important role in the inheritance of all studied traits except for grain yield and number of ears/plant, where non-additive gene effects played an important role in the inheritance of these traits. Moreover, the magnitude of σ<sup>2</sup><sub>GCAxLoc</sub> interaction was higher than σ<sup>2</sup>SCA x E interaction for all studied traits, indicating that the additive type of gene action was affected more by environment than non-additive one.
