This study was conducted to investigate the effects of organic, NPK, and biofertilizers on the yield of two cowpea varieties grown under arid land conditions. Two cultivars of cowpea (Karim-7 and Dokki-331) were evaluated using different fertilizer types. The fertilizers examined were organic (farmyard manure (FYM) and chicken manure (CHM)) and biofertilizers (effective microorganisms (EM1) and technology of smart fertilizer (TS)) in addition to NPK treatments (NPK (50 kg/fed), NPK (100 kg/fed), EM1 (15 m3.fed-1) + NPK (50 kg/fed), TS (15 m3.fed-1) + NPK (50 kg/fed). A randomized complete block design (RCBD) with 16 treatments and three replications was used to set up the experiment. The measured yield parameters were seed number/plant, pod length, seed number/pod, pod number/plant, dry yield/plant, dry yield/m2, bio yield, pod weight, 100-seed weight, and grain yield. The results cleared that the cultivar dokki-331 under EM1 biofertilizer + NPK (50 kg/fed) combination treatment was the superior practice for increasing all studied traits.

Using integrated in silico and in vitro experiments, the antiviral capabilities of green tea and licorice extracts were evaluated against the tobacco mosaic virus (TMV). It was noted that the number of induced necrotic local lesions of TMV decreased by increasing extract concentrations and thus it is considered concentration dependent on the extracts’ active compounds. Properties of eleven compounds belonging to licorice and green tea were obtained from databases to examine their activities in silico. A molecular docking simulation was performed between these agents and the protein coat of the tobacco mosaic virus (TMV). The highest effective compounds were glycyrrhetic acid, liquiritin and EGCG. ADMET studies revealed good overall properties of nine non-toxic compounds based on their predicted pharmacokinetic, physicochemical, drug-likeness and toxic properties. Based on docking energy and mode of interaction, these compounds showed strong binding with the protein coat of TMV. The antiviral effect may be due to the most effective compounds with the highest affinity namely glycyr-rhetic acid, liquiritin and isoliquiritin. As a conclusion, the promising value of our titled extracts is the anti-TMV activity and pharmacokinetic and physicochemical properties of their active constituents.

The Red and White pakestanian mulberry cultivars and Baladi mulberry trees were propagated by using medium hardwood cuttings pre-pared in November, December and January, and treated with the growth regulators IBA and NAA (0, 2000, 4000 and 6000 ppm) during 2020 and 2021 seasons. The hardwood cuttings treatment was planted in wooden frames inside the greenhouse in a cultivation medium consisting of peat moss and sand (1:3 v/v respectively). Data showed that Baladi mulberry cultivar gave the highest values of rooting percentage while the White Pakestanian gave the highest values for the number of roots per cutting. Concerning growth regulator treatments, IBA at 6000 gave the highest significant number of roots per cutting followed by NAA at 6000 ppm. In the interaction between the two studied factors, the highest rooting percentage was found by NAA at 6000 ppm for Baladi and White cultivars. While the highest values of root number and root length were resulted by IBA at 6000 ppm followed by NAA at 6000 ppm for Baladi and White mulberry cultivars. The C/N ratio in Baladi and White cultivars cuttings was highest in hardwood cuttings prepared in November. While the values of C/N ratio in Red mulberry cultivar cuttings were highest in hardwood cuttings prepared in January.

The research was conducted to assess the impact of various organic and inorganic fertilizers on the growth and yield of Marigold (Tagetes erecta L.) var. Calcuttia Single using a randomized complete block design with eight treatments including vermicompost, farmyard manure, poultry manure, charcoal, NPK fertilizer, and their combinations in triplicates. Measurements of vegetative and reproductive parameters were recorded at 35, 55 and 85 DAT. Results revealed that compared to the control, poultry manure and vermicompost, singly or combined with NPK, significantly enhanced both vegetative and reproductive traits. Poultry manure resulted in the tallest plants (126.21 cm), the highest number of branches (29.93), and the largest flowers (14.11 cm diameter), with the earliest flowering (51.33 days). Vermicompost showed effectiveness in plant height (117.37 cm), number of branches (28.80), plant spread (81.43 cm) and flower number (40.47) The control plot exhibited the least effectiveness in all parameters. These findings highlight the significant role of organic fertilizers in enhancing the growth and yield of Marigold (Tagetes erecta L.) var. Calcuttia Single.
