Three nitrogen rates (75, 85 and 95 kg N/fad) were arrange in main plots, two yeast rates (10, 15 g/l) were devoted in sub-plots, whereas, sub-sub plots were allocated to number of magnesium applications at rate of 6 g/l  (without addition, one, two and three times). Main results could be summarized as follows: Increasing nitrogen rates from 75 to 95 kg N/fad significantly increased the most characters under study such as, root dimensions, top/ root ratio, in the second seasons sugar beet yields (top, root and sugar), impurities values as well as sugar loss in molasses and alkaline coefficient in term (AC). On the other direction, juice quality significantly decreased such as sucrose%, extractable sugar, extractability and purity percentages as nitrogen level increased. Application of yeast at the rate of 15 g/l significantly affected yield and quality and caused a significant increase in the most characters under study as compared to the rate 10 g/l which gave lowest values for all traits under studied trails. Application of study take the same trend of nitrogen fertilizer effect. Number of magnesium application as foliar spray at the rate of 6g/l significantly affected the most studied characters. Three times, significantly increased sugar beet yield and its attributes, while it significantly decreased quality values for some traits as sucrose%, extractable sugar and extractability percentages.  It could be concluded that adding nitrogen fertilizer at the rate of 95 Kg N/fad and yeast at the concentration of 15g/l as well as application of magnesium three times at the rate of 6g/l is a recommended treatment for maximizing sugar beet yield and its quality under these conditions of this study.  }, keywords = {}, url = {https://jpp.journals.ekb.eg/article_46178.html}, eprint = {https://jpp.journals.ekb.eg/article_46178_0e830e6a951cbf0a3e331634ef5d015d.pdf} } @article { author = {El-Dakkak, A.}, title = {Inheritance of Seeds Color and Some Economic Characters in Pea (Pisum sativum L.)}, journal = {Journal of Plant Production}, volume = {7}, number = {8}, pages = {829-835}, year = {2016}, publisher = {Mansoura University, Faculty of Agriculture}, issn = {2090-3669}, eissn = {2090-374X}, doi = {10.21608/jpp.2016.46182}, abstract = {The present study was carried out during four growing winter seasons (2012/2013 to 2015/2016) at Shandweel Agricultural Research Station, Research Center Ministry of Agriculture Egypt. The basic material used in this study consisted of (Master-B x Mammoth melting sugar) F1 hybrid which  all plants have purple flowers and both round and mottled in seed shape and color, respectively and planted  to produce F2 population which isolated two population categories (purple flowers, mottled seeds and white flowers, green seeds). Data of both F3 and F4 generations were studied in four groups, i.e. Wrinkled green seed, Round green seed, Round mottled seed and Wrinkled mottled seed.  Analysis of variance showed significant differences among the genotypes for all characters. Mean values for F1 generation were high in shilling %, no. of pods/plant and green pod yield. Estimates of the genetic parameters from the generation means indicated significant both additive [d] and dominance [h] gene effects in some traits of the base population, i.e. plant height, No. of pods/ plant, Shelling %, 100-fresh seed weight and Fresh pod yield/plant. Inbreeding depression in green seeds segregations was uniformly less in magnitude than that obtained in the mottled seeds segregations. Most F2 progenies showed strong evidence of transgressive segregation above the parental values of both green and mottled seed segregations in most traits. Small differences were observed between PCV and GCV for all the characters. High heritability associated with high genetic advance was observed for most studied characters. The potence ratio displayed over dominance in the inheritance of Pod length, Pod weight, No. of pods/ plant, Shelling% and fresh pod yield plant. The estimates of  broad sense heritability after the end cycle of selection were medium for number of  seeds/pod in the wrinkled (52.33%), round  (50.65%) of green seed and only round  of mottled seed (56.74%), while it was of high  magnitude for each of all other traits in all categories. From the results, therefore, it is demonstrated that a considerable amount of readily fixable variation is present and available for the plant breeder to manipulate. It could be noticed that selection for plant height trait in mottled seed (Round and wrinkled) category and for pod green yield trait in only round seed category generally, was better than any other categories over all comparisons after the 2nd cycle.  Means of 100-seeds weight,  No. of pods/ plant and fresh pods yield were higher in round seed compared with wrinkled one of both green and mottled seed while No. of seeds/pod exhibited the reverse trend in both F3 and F4 generations.}, keywords = {}, url = {https://jpp.journals.ekb.eg/article_46182.html}, eprint = {https://jpp.journals.ekb.eg/article_46182_bb88e23005333744984245c070a926dc.pdf} } @article { author = {El-Dakkak, A.}, title = {Genetic Improvement for Yield and Quality Characters in Pea By Using Selection}, journal = {Journal of Plant Production}, volume = {7}, number = {8}, pages = {837-842}, year = {2016}, publisher = {Mansoura University, Faculty of Agriculture}, issn = {2090-3669}, eissn = {2090-374X}, doi = {10.21608/jpp.2016.46191}, abstract = {The present study was carried out at Shandaweel Agricultural Research Station, Sohag Governorate during five winter growing seasons (2011/2012, 2012/2013, 2013/2014, 2014/2015 and 2015/2016) using two F3- populations stemmed from two breeding methods for cross between two varieties of pea (Pisum sativum L.) and pedigree selection procedure was applied to obtain new pure lines of pea having intermediate vegetative growth and desirable yield traits. The mean values for each of all the studied traits after the third cycle of selection (F6 generation)were higher in population II than each of population I, parents and check cultivar. The broad sense heritability was high and ranged from 82.24 to 98 % in all studied traits of all selected generations in population I and population II except number of seeds/pod which seriously was affected by the changes in the environmental factors, so it was low and ranged from 43.45 to 54.35. Also, the actual selection response was high compared with the expected response in F6 generations for number of days to 50% flowering and number of seeds per pod in both populations I&II as well as both number of pods/plant and dry weight of seeds yield/plant in population II only.  The realized gains relative to the parents and check were higher in F6-population II than population I for most studied traits.

The aim of the experiments was to compare growth, yield and its component and nitrogen and carbohydrate  contents as well as to determine base temperature and accumulated heat units of okra as influenced with transplanting date and nitrogen source. Five transplanting dates were investigated which were; Jan.15th, Febr.1st, Febr.15th, March.1st and March.15th. Four nitrogen sources were studied which were: Urea, ammonium nitrate, ammonium sulfate and compost; the applied quantity of each source contained 90 nitrogen unit; beside control treatment which was ammonium nitrate at rate of 60 nitrogen unit (the recommended dose).  Seeds of okra were sown in artificial media under greenhouse for 40 days before transplanting in the field. Results revealed that survival ratio and the investigated growth parameters, chlorophyll content, yield and its components, nitrogen and carbohydrates of pods and nitrogen use efficiency were increased with delaying planting date. Compost followed by urea treated plants gave the highest values. Interaction results showed that compost treated plants transplanted on March 15th had the best growth and yield. Base temperature of okra, Balady cultivar was 6.55 °C (43.8 °F). Accumulated heat units above base temperature required till the first flower was 982.8 ± 44.5 heat units without insignificant differences among different transplanting dates. This indicated that flowering time was dependent upon accumulated heat units rather than number of days required for the first flower. High significant positive correlations were found between yield of pods and either plant dry weight, leaves area, number of leaves / plant or number of pods per plant. Regression coefficients indicated that for each increase of one pod / plant, yield of okra pods correspondingly increased by 140.18 kg pods / fed.        }, keywords = {Transplanting date,nitrogen sources,okra (Abelmoschus esculentus L.),Growth,yield,pod quality,Nitrogen use efficiency,base temperature,accumulated heat units}, url = {https://jpp.journals.ekb.eg/article_46206.html}, eprint = {https://jpp.journals.ekb.eg/article_46206_207d8af78307df2bd1baa74472fe05b8.pdf} } @article { author = {Stino, R. and AL-Shenawy, E. and AL-Shobaki, M. and Fouad, H. and Bakhoum, Nessrin}, title = {Ellevation of Uranium Stress on Olive Budlings by Organic Matter Amendment}, journal = {Journal of Plant Production}, volume = {7}, number = {8}, pages = {903-910}, year = {2016}, publisher = {Mansoura University, Faculty of Agriculture}, issn = {2090-3669}, eissn = {2090-374X}, doi = {10.21608/jpp.2016.46208}, abstract = {This study was carried out through two successive seasons of 2012&2013. A pot experiment was carried out on Kalamata Olive budlings to investigate  effects of adding uranium to the nutrient solution at 6 concentrations. The effect of organic matter amendment in the media to diminish the adverse effects was also assessed. The evaluated parameters were vegetative growth parameters, biomass, leaf  total  chlorophyll, leaf macro-nutrients and uranium accumulation. The attained data clarified clear adverse effects, which were in proportional to increasing the added uranium. Amending the growing media with farm manure showed significant palliative effects, which increased with increasing the application rate.It was concluded that the adverse effects related to uranium application in our opnion is basically due to decreasing the macro nutrients absorption and this is evident by its' decreasing concentration in the leaves. This was reflected on the decrease total chlorophyll in the leaves leading to lowering their photosynthetic activity. This resulted in decreasing the vegetative growth and thereby decreasing the biomass. The effect of adding organic matter might be attributed to their effect on adsorbing uranium which led to a decrease in its' accumulation and thus reducing its' adverse effects. In addition to the nutritive effects of the organic matter, which enhance growth parameters and biomass.}, keywords = {olive – uranium- adverse effects- organic matter}, url = {https://jpp.journals.ekb.eg/article_46208.html}, eprint = {https://jpp.journals.ekb.eg/article_46208_56769cf3fd4b16f297866176e2dac6d2.pdf} } @article { author = {Gibril, I. and Wasfi, M.}, title = {Effect of Salicylates on Nitrate Content and Reduction in Salt – Stressed Zea mays L.
