The obtained results showed significant effects of aeration levels and different fertilization rates on studied vegetative growth parameters and chemical constituents of paspalum plants. During both seasons, significant increases were found in clipping fresh and dry weights (g/m2), chlorophyll a and b(mg/g fresh weight) and macronutrient percentage of paspalum plants grown under all aeration levels but the highest significant values were found under the fourth level of aeration (A3) followed by the third aeration level (A2) then the second one(A1) and at least control (A0). Also, the second application rate of fertilization (F2) led to a significant increase in studied growth parameters and chemical constituents of paspalum plants compared to the first rate of fertilization(F1). Regarding the interaction effect, the obtained data showed that the highest significant values of investigated growth parameters and chemical constituents were recorded in the treatment of A3F2, while the lowest values were those of A0F1 treatment during the both seasons. }, keywords = {Paspalum,Aeration, Fertilization ,vegetative growth}, url = {https://jpp.journals.ekb.eg/article_36361.html}, eprint = {https://jpp.journals.ekb.eg/article_36361_047e918db30cecd4f8df64eb942dba3a.pdf} } @article { author = {Serag, M. and Khedr, A. and Shaaban, Heba and Alhlak, O.}, title = {Ecological Study on Two Grass Species in the Coastal Wetlands of the Nile Delta, Egypt}, journal = {Journal of Plant Production}, volume = {9}, number = {7}, pages = {587-592}, year = {2018}, publisher = {Mansoura University, Faculty of Agriculture}, issn = {2090-3669}, eissn = {2090-374X}, doi = {10.21608/jpp.2018.36363}, abstract = {This work studied the forage quality of two grass species growing on coastal wetlands of the Nile Delta.

Thirty-six associated species were recorded in the study area, life form ranging from Therophytes to hemicryptophytes and Phanerophytes. The CCA-biplot ordination revealed that Leptochloa fusca (L.) had an intermediate correlation with Na+ and Ca2+ and strong correlation with K+ and organic matter. The productivity of the studied species increased during the spring and summer. This means that they can cover the summer needs for forage. The pH of the soil varied from 7.14 to 8.25 for the different habitats of study area. The soil electrical conductivity varied from 0.19 to 4.00 ds m-.

A split-plot with three replicates was the experimental design. The vertical-plots to three compost rates i.e. without compost (control treatment), 50 % of the recommended dose (2 tons compost/fed) and 100 % of the recommended dose (4 tons compost/fed).The horizontal plots were devoted to four treatments of foliar spraying with some biostimulant substances i.e. foliar spraying with brassinolid at the rate of 10 ppm, moringa extract at the rate of 200 ppm, chitosan at the rate of 200 ppm and tap water (control treatment). The most important results can be summarized as follows: The highest values of vegetative growth characters, pod yield and its components as well as quality of snap bean pods were resulted from fertilizing with (4 tons compost/fed) 100 % .On the contrary, the lowest values of growth characters, pod yield and its components and chemical composition of snap bean pods were obtained from plants not treated with compost (control treatment).

Susceptibility index (SI), Seed yield /plant as well as net weight after discarding the all negative factors which affect the final yield were taken as gauge of susceptibility of studied lines. Actually, the results indicated that the studied lines greatly differed to the attack of C. maculatus. According to (SI)i.e. the line with high values of SI, high number of progeny, weight losses and shorter life cycle were classified as susceptible. In contrast, the lines with intermediate S.I (5.1-7.5) and revealed lower number of adults emerged (lower, weight loss and longerlife cycle were considered tolerant or moderately resistant (MR). The results clearly indicated that the complete resistant lines were relatively absent. Furthermore, appositive relationship was fond between the physic-chemical characters and infestation with C. maculatus.  According to S.I, seed yield/plant, net weight the lines 2 and 16 were the most tolerant, while line 14 and 4 were the most susceptible one. In addition, that the mid October was the suitable sowing date where it actualized the higher seed yield along the two planting seasons.

In order to early maturity character, the promising breeding line 2 as an early mature faba line that characterizes with tolerant to insect infestation along with high yield potential, especially under the stresses associated with early sowing date.
