Two experiments were conducted at the greenhouse and labs. of the Agric. Bot. Dept., Fac. of Agric., Mansoura Univ., and Seed Technology Research Unit,  Field Crops Research Institute,  Agric. Research Center, during the two growing Seasons 2010 and 2011. Salt stress was imposed by dissolving natural salt crust in tap water to obtain saline irrigation water at 5000,6000,7000,8000 and 9000 mgL-1. Results indicated that all tested substances partially restored the salinity induced decrease in seed yield, with AsA and YE were the most effective in this respect. Total phenols, proline and endogenous ascorbic acid contents were increased in response to either salinity stress , stress alleviators or their interaction. The ratio between Na and K in both shoots and roots was decreased in response to stress alleviators. In addition, seed oil and protein contents were increased in salt–stressed , stress alleviators- treated plants compared with salt-stressed only plants. In addition, results indicated that the alleviative effect of the applied stress mitigators was evident not only on salt-stressed plants but also on their descendant seeds where their germination, vigour, and seedling establishment were enhanced. It is concluded that AsA, SA, SWE and YE, preferably the first and the latter, could be used to maintain yield of soybean growing in salt-affected soils.}, keywords = {soybean, Glycine max,salt- stress tolerance,ascorbic acid,Salicylic acid,seaweed extract,yeast extract}, url = {https://jpp.journals.ekb.eg/article_51925.html}, eprint = {https://jpp.journals.ekb.eg/article_51925_6728aeeb40c7d1528c007e840391e777.pdf} } @article { author = {Nemeat Alla, H. and El-Geddawy, Dalia and Makhlouf, B.}, title = {EFFECT OF YEAST APPLICATION METHOD AND NUMBER ON YIELD AND QUALITY OF SUGAR BEET UNDER DIFFERENT LEVELS OF NITROGEN}, journal = {Journal of Plant Production}, volume = {6}, number = {9}, pages = {1475-1490}, year = {2015}, publisher = {Mansoura University, Faculty of Agriculture}, issn = {2090-3669}, eissn = {2090-374X}, doi = {10.21608/jpp.2015.51932}, abstract = {Two field trials were carried out in the two successive seasons of 2012/2013 and 2013/2014 at EL-EttehadVillage, Kafr ELSheikh Governorate to study the grow yield and quality of sugar beet as affected by methods and numbers of yeast application in combination with nitrogen levels. The study included 24 treatments which were the combination between two application methods of yeast (soil 15 g/l and foliar 5 g/l), four application numbers (0, 1, 2 and 3) and three nitrogen fertilization levels (60, 80 and 100 kg/fed). A split–split plot design with three replications was used. Yeast application method were assigned the main plots whereas the nitrogen levels were allocated in the sub plots and number of yeast application were occupied the sub–sub plots. The results obtained pointed out that root dimensions as well as root/top ratio positively and significantly responded to yeast application methods, yeast foliar application over passed soil application with respect to root dimensions and root/top ratio. Data showed that juice parameters of sugar beet roots in terms of sucrose and purity percentages significantly affected by application methods of yeast. The foliar application recorded the positive and significant superiority for both of sucrose and purity percentages. Application methods significantly effected on the values of extractable sugar % in both growing seasons, however the values of sugar loss to molasses % insignificantly affected by yeast application method. It could be noted that the highest values extractable sugar % was recorded with foliar application at the meantime the lowest values of sugar loss to molasses % was attained with yeast foliar application. Foliar application of yeast attained an increase in root, top and sugar yields amounted by 38.43 % & 12.14 %, 17.87 % & 17.54 % and 67.56 % & 27.52 % in the 1st and 2nd season, respectively, over those of soil application of yeast. It could be noted that the most effective of yeast foliar treatment was that on sugar yield. The available results revealed that sugar beet plants appeared a continuous and significant increase in root dimensions due to the increase in the additional rates of nitrogen up to 100 kg N/fed.
