  • Response and productivity of Garlic (Allium Sativum L.) by different levels of potassium fertilizer in farm soils

    • 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...

  • Strand thinning of Khadrawi date palm cultivar in relation to yield and fruit quality

    • 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...

  • Synergistic effect of P and K interaction on yield and yield components of mungbean (Vigna radiata (L.) Wilczek) varieties

    • 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.

  • The effect of the natural extracts of garlic or Eucalyptus on the growth, yield and some chemical constituents in quinoa plants

    • 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.

  • The physiological effect of pre-soaking with tryptophan on sugar beet (Beta vulgaris L.) productivity under different levels of salinity stresses

    • 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...

  • Zinc-oxide and nano ZnO oxide effects on growth, some biochemical aspects, yield quantity, and quality of flax (Linum uitatissimum L.) in absence and presence of compost under sandy soil

    • 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...
