This study was conducted during Rabi 2017-18 under net house condition, to evaluate the synergistic effects of vermicompost and beneficial microbes on pea plants. The experiment was laid out in completely randomized design with three replication and fifteen treatments. The result indicated that among all treatment, a treatment V4 was found to be best in terms of all growth parameters and plant defense-related compounds. The treatment combination of M1V3 has given best results followed by treatment M2V2. The results from this experiment demonstrated the strong synergistic effects between vermicompost and two microbes, as they improved the soil nutrients status by supporting growth and development of plants by producing growth hormones and also protected the plants from diseases by enhancing the production of defense - related compounds.

Determination of the Hajj Pilgrim Departure Pattern is currently very much needed by the Haj organizers, especially at the Office of the Ministry of Religion Lubuk Pakam because the schedule of pilgrims' departure is still not regular, causing accumulation of data on pilgrims who will be departed to the holy land, but with The number of pilgrims who will depart for the pilgrimage is made to determine the pattern of Hajj departure with the C4.5 Algorithm to make it easier for the hajj organizer staff to determine what age should be sent to the holy land.

Aloe vera is an important medicinal plant of Asphodelaceae (Liliaceae) family. It is widely used owing to its wound healing, anti-inflammatory, immunity, antidiabetic, antioxidant, laxative, antibacterial, antifungal and antiviral properties. Similar to other crop plants, Aloe vera is infected by several plant pathogens that deteriorate its yield and quality. Among various fungal diseases, black spot disease caused by Colletotrichum gloeosporioides (Penz.) Penz. & Sacc. is the most serious disease which not only reduces the crop yield and market value but also the antioxidant properties and other medicinal efficacy of the plant. C. gloeosporioides is commonly controlled by chemical fungicides but due to the limitations of applying chemical control methods on medicinal plants, there is a need to look for some safe alternatives. The objective of this paper is to review the previous work on etiology, symptomatology and management of C. gloeosporioides (Penz.) Penz. & Sacc. through botanicals (natural plant extracts), biocontrol agents and some safe and ecofriendly chemicals like Azoxystrobin.
