Abstrak :
The soybean plant is one of the important food plants related to the nutrients contained in it, especially in its high protein content. The necessity for soybeans in Indonesia has not been equaled by an increase in production. One of the influencing aspects is the existence of pests. The intention of this research was to assess botanical insecticides on the growth and result of soybean (Glycine max (L) Merrill.) Anjasmoro variety.This research was conducted in Getas Village, Wonosalam District, Demak Regency, Central Java, Indonesia, with an altitude of 100 meters asl (meters above sea level) and dark gray gromosol soil types. The implementation of research from July 2020 to October 2020.The method used was a randomized completely block design (RCBD) with a single factor. The kinds of treatment were: soursop leaf extract with a concentration 150 g/l, 300g/l, 450g/l; tobacco leaf extract with concentration 150 g/l, 300g/l, 450 g/l ; a combination of soursop leaf extract and tobacco 150 g/l, 300 g/l, 450 g/l.The results obtained indicate that the concentration of botanical insecticides affects plant growth. This is indicated by an increase in several growth parameters. The most significant growth occurred in the combination treatment of soursop leaf extract and tobacco leaf with concentration 450 g/l.
In progression, the parameters of plant height, amount of leaves, amount of pods, amount of seeds, weight of seeds, weight of 100 seeds and intensity of wart incursion were 59.40 cm, 11.73 leaves, 40.60 pods, 87, 16 seeds, 11.04 g, 16.80 g. Whereas in the observation of the intensity of pest incursions, an effective treatment to suppress pest incursions was a combination of soursop leaves and tobacco with a concentration of 450 g / l. The results obtained at observations at the age of 84 dap (dayas after planting) were 36.20%.
