Abstract

Nezara viridula is a pest that can reduce soybean production both in quality and quantity. Currently efforts in controlling N. viridula still use synthetic chemical insecticides that can have negative impacts. One solution to reduce reliance on synthetic chemical insecticide is the use of entomopathogenic fungi Beauveria bassiana. The purpose of this study was to test the ability of several concentrations of entomopathogenic fungi Beauveria bassiana Vuillemin Riau local green ladybugs for pest control N. viridula on soybean plants. Research prepared using completely randomized design (CRD) with 6 treatments and 4 replications. The treatment used is some concentration of B. bassiana consists of 6 treatments are: 0 g/ l of water, the concentration of B. bassiana 70 g / l of aquades, the concentration of B. bassiana 75 g / l of aquades, the concentration of B. bassiana 80 g / l of aquades , the concentration of B. bassiana 85 g / l of aquades, the concentration of B. bassiana 90 g / l of aquades. The results showed concentrations of B. bassiana 90 g / l of aquades is more effective in controlling N. viridula, but to fulfill the concept of integrated pest control concentration of 80 g / l of aquades (17.42 x 107 kon / ml) are considered better because it can lead to early N. viridula death for 64.25 hours, lethal time 50 (LT50) for 135.75 hours, and caused total mortality 85% for 9 days (209 hours).

Abstract

Edamame soybean is the plant from Japan. Edamame soybean production has a relatively short lifespan than regular soy because it is harvested when the pods are young. Bioslurry is one of organic material that can be applied as a liquid organic fertilizer on edamame soybean, but the giving of bioslurry only in the short term has not been able to occupied the nutrient requirements for edamame soybean, so it needs the addition of organic fertilizers such as  anorganic fertilizer N, P, K. This study aimed to get the interaction effect of bioslurry and N, P, K fertilizers on the growth and production of edamame soybean (Glycine max (L) Merrill) and get best treatment. This study was a factorial experiment arranged in Randomized Block Design (RBD) consisting of 2 factors and 3 replications. The parameters observed were plant height, percentage of effective root nodules, plant dry weight, days to flowering, number of pods per plant, pod percentage pithy, weight of pods per plant and weight of pods per plot. The results showed that the interaction effect of bioslurry and fertilizer N, P, K did not affected the plant height and days to flowering and affected the percentage of effective root nodules, dry weight of pods per plant, pod percentage pithy weight of pods per plant and weight of pods per plot. Based on the research results of bioslurry application (500 ml /plant) and N, P, K (3.3+ 9.9+8.8)g/plot fertilizers gives the best results on the growth and production of soybean edamame.
