Authors: Ahmed, A.M.A.; Advisor: -; Participants: Talaat, I.M.; Khalid, K.A. (2019) - The 5 mg/L of SODSE resulted in the highest values of growth, yield, photosynthetic pigments, protein, and antioxidant enzymes (identified in leaves) while 30 mg/L of HEXAC produced the greatest amounts of protein that identified in roots. The SODSE and HEXAC caused significant increases on growth, yield, and chemical constituents of M. oleifera. This research paper discovered that M. oleifera plants can be successfully grown under SODSE and HEXAC as they possess relatively high yield and chemical constituents. So this trial will help the farmers, ministry of agriculture, and drug companies to improve the yield and active components (protein) as natural sours of drug industries.

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.

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.
