Authors: Sadak, M.S.; Advisor: -; Participants: - (2019) - Foliar application of AgNPs with different concentrations (20, 40, and 60 mg/l) improved the growth parameters of fenugreek plant (e.g., shoot length, number of leaves/plant, and shoot dry weight) and increased some biochemical aspects such as photosynthetic pigment (chlorophyll a, chlorophyll b, and carotenoids) and indole acetic acid (IAA) contents thus enhanced the yield quantity (number of pods/plant, number of seeds/pod, weight of seeds/plant, and seed index) and quality (carbohydrate%, protein%, phenolics, flavonoids, and tannins contents) of the yielded seeds as well as increasing antioxidant activity of the yielded seeds.

Authors: Dawood, M.G.; Advisor: -; Participants: Sadak, M.S.; Abdallah, M.M.S.; Bakry, B.A.; Darwish, O.M. (2019) - Application of biofertilization treatments (Mycorrhiza, milk whey, yeast, and yeast extract as soil drench or foliar application, respectively) affects significantly most of the studied characters. Data show significant variations in vegetative growth parameters, photosynthetic pigments, carbohydrate, phenolic content, as well as seed yield, yield components, and nutritive value (oil, protein, flavonoid, and phenolic content) of the yielded seeds between three flax cultivars. Sakha-1 cultivar showed more adaptation to the conditions of sandy soil than the linola and Line-3 cultivars and reflected on the highest significant value of seed yield. All applied treatments caused significant...

Authors: Sadak, Mervat Sh.; Advisor: -; Participants: Abd El-Hameid, Asmaa R.; Zaki, Faten S. A.; Dawood, Mona G.; El-Awadi, Mohamed E. (2020) - Cysteine treatments could alleviate the adverse effect of salinity stress on growth and yield of soybean plant through increasing photosynthetic pigments; proline content; N, P, and K contents; superoxide dismutase and catalase activities; and oil% accompanied by decreases in H2O2 and MDA contents as compared with their corresponding controls. In addition, cysteine treatments and/or salinity stress exhibited differences in protein pattern from 112 to 19 kD molecular weight. The appearance of new protein bands reflected the expression of cysteine treatments and salinity stress.

Authors: Ahmed, Sium; Advisor: -; Participants: Moni, Bilkis Mehrin; Ahmed, Shawon; Gomes, Donald James; Shohael, Abdullah Mohammad (2020) - Growth and yield measurements were decreased with salinity stress. High levels of both proline and trehalose recorded the highest values of total soluble sugars, proline, and free amino acids in both unstressed or salinity stressed plants with or without compost addition. The use of compost in soil for cultivating quinoa plants with either proline or trehalose treatments increased growth parameters, photosynthetic pigments, and yield attributes. In addition, these treatments improved the accumulation of some organic solutes in leaves and promoted antioxidant enzyme activities.

Authors: Wali, Asal M.; Advisor: -; Participants: Kenawey, M. K.; Ibrahim, O. M.; Lateef, E. M. Abd El (2022) - Introducing new crops to reduce the nutritional gap in Egypt is an important target. One of these crops is Quinoa which is characterized by high nutritional value with multiple food uses. However, it will compete with other winter crops, so it is candidate to grow in marginal lands like calcareous soils. Meanwhile, planting density and N requirements are not known under such conditions; therefore, this work was undertaken in calcareous soil Caco3 > 50%.

Authors: Jiku, Md. Abu Sayem; Advisor: -; Participants: Alimuzzaman, Md.; Singha, Ashutus; Rahaman, Md. Arifur; Ganapati, Ratan Kumar; Alam, Md. Ashraful; Sinha, Shata Rupa (2020) - In this study, six levels of K viz. 0, 100, 125, 150, 175, 200, 250 kg ha−1 were used as treatments. All the parameters, i.e., plant height, number of leaves plant−1, fresh and dry weights of leaves (g plant−1), fresh and dry weights of bulb (g plant−1), bulb diameter, and number of cloves bulb−1 significantly varied due to different doses of K application. The maximum total yield and size of garlic bulb were obtained with potassium application at 200 kg ha−1. Potassium at 200 kg ha−1 produced the highest fresh and dry weights of bulbs and leaves, diameter, moisture content, number of cloves, and yield as compared to the other treatments. The uptake of nutrients like N, P, K, S, Ca, M...

Authors: Moustafa, A. R.; Advisor: -; Participants: Abdel-Hamid, N.; Abd El-Hamid, A.; El-Sonbaty, M. R.; Abd El-Naby, S. K. M. (2019) - The present results indicated that strand thinning by removing 30% of the total number of strands gave the lowest bunch weight and yield per palm compared to thinning 15% and control treatments during the two seasons of study. Also, removing 30% of the total number of strands improved some physical properties, i.e., fruit weight, flesh weight, fruit length, and fruit diameter than control in both seasons. All strand thinning treatments improved some chemical properties such as TSS %, total sugars %, and reducing sugars % than control (without thinning). However, both 15 and 30% strand thinning treatments had no significant effect on nonreducing sugars %, total acidity %, and tannins c...

Authors: Abd El Lateef, E. M.; Advisor: -; Participants: Wali, Asal M.; Abd El-Salam, M. S. (2021) - The results showed that there were varietal differences in yield and yield components regardless fertilizer application. Either phosphatic or potassic fertilization significantly increased mungbean yield and yield components traits. Significant effects due to the interaction (V × P) were reported on yield component traits in both seasons. Furthermore, the triple interaction (V × P × K) indicates that synergistic effect was reported for the two varieties and was more clearer for V2010 where it needed both of P and K nutrients to out yield the greatest seed yield ha−1, while Kawmy-1 gave the greatest seed yield ha−1 without K application.

Authors: El-Rokiek, Kowthar Gad; Advisor: -; Participants: Dawood, Mona Gergis; Sadak, Mervat Shamoon; El-Awadi, Mohamed El-Sayed (2019) - The results of vegetative growth stages indicated increases in quinoa growth due to the treatments with different concentrations of the two mentioned extracts. The results also revealed increases in photosynthetic pigments constituents (chlorophyll a, chlorophyll b and carotenoids) of quinoa leaves. The results also indicated increases in yield and oil content as well as different studied metabolic activity.

Authors: Hozayn, M.; Advisor: -; Participants: Abd-Elmonem, A. A.; Samaha, Ghada M. (2020) - The results revealed that the pre-soaking in tryptophan treatments (2.5 mM) were the most effective treatments under different salinity levels and caused significant increases in all tested parameters of this study. Moreover, increasing salinity levels decreased significantly the root purity parameters and increased impurity parameters of sugar beet. The DS-9004 cultivar gave the highest values of all studied parameters compared with the LP-15 cultivar under different salinity levels with tryptophan (2.5 mM). Chlorophyll a content and chlorophyll a/b ratio, as well as carotenoids content, were highest in DS-9004 cultivar, while chlorophyll b content was highest in LP-15 cultivar at 75...

Authors: Sadak, Mervat Shamoon; Advisor: -; Participants: Bakry, Bakry Ahmed (2020) - The obtained results showed that adding of compost to the sandy soil by 3.0 ton/fed, increased markedly growth parameters (shoot and root length (cm), fresh and dry weights (g), photosynthetic pigments (chlorophyll a, chlorophyll b, carotenoids, and total pigments (μg/g fresh wt)), free amino acids and proline (mg/100 g dry wt), total carbohydrate percentage, yield quantity and quality (technical shoot, fruiting zone lengths and plant height (cm), No. of fruiting branches/plant and No. of capsules/plant, weight of straw (g), weight of 1000 seeds (g), biological yield (kg/fed), seed yield (kg/fed), and straw yield (kg/fed)), oil percentage, and oil yield (kg/fed) compared to control tr...
