Abstract

S. litura F pests are widespread in Indonesia covering 22 provinces with an average attack area of 11,163 ha/year.  This pest is polyphag causing damage to the leaves (defoliation) with crop loss can reach 85% even to failed miserably.  The application of biotechnology derived from local resources is a very appropriate alternative to controlling S. litura, namely Bacillus cereus strain ATCC 14579,  Bacillus subtillis subsp. subtilis strain 168  Bacillus siamensis strain KCTC13613, Azotobacter sp. and Pseudomonas fluorescens isolated from the LMO banana stem bud.  The aim of this study is to determine the potential of 5 types of bacteria that were consortified as S. litura pest bio-control agents. The research consisted of stages, namely 1) bacterial compatibility test which would be consortified; 2) invitro bacterial consortium potential test on S. litura F. larvae.  The results showed that the bacteria B. cereus strain ATCC 14579, B. subtillis subsp. Subtilis strain 168 B. siamensis strain KCTC13613, Azotobacter sp. and P. fluorescens are compatible with each other so that they can be consortified. These 5 types of bacteria are single less potential as S. litura pest bio-control agents because they cause low larval mortality, but a consortium of 5 bacteria can cause larval mortality by 70% . Keywords: biocontrol agents, Spodoptera litura, bacterial consortium, LOM banana stem bud

Abstract

Mulberry plant (Morus alba) is a plant that has social and economic importance. This plant development is often done to harvest the fruit and leaves. The social importance can be found in that this plant, especially in its leaves, is used in silkworm feed (Bombyx mori) and then silk is used in traditional clothes in Indonesia. Cultivation of mulberry plant (leaves and fruit) ideally by Integrated Pest Management (IPM) is necessary so that mulberry plants grow ideally and leaves have high quality and quantity without becoming a source of inoculum for pests and diseases of silkworm maintenance. Mulberry cultivation is generally carried out without using pesticide input so it is interesting in monitoring pests and natural enemies in the mulberry ecosystem. The research was conducted on two varieties of mulberry plants, namely Morus alba var. Kanva-2 and Morus cathayana in the same agroecosystem. Observation of pests and natural enemies was carried out using yellow sticky traps (YST) and pitfall traps (PFT). The orders and families found in the two varieties showed acroceridae family of 37.81% in the YST and hypogastruridae family with a value of 83.76% in the PFT observation.Keywords: IPM, Morus alba, natural enemies, pest, trapping.

Abstract

Arbuscular Mycorrhizal Fungi (AMF) are known to have potential as biological agents controlling plant pathogens. This study aims to obtain indigenous AMF isolates that can suppress the attack of Sclerotium rolfsii which causes stem rot disease in peanut. The method used is an experimental method with a Completely Randomized Design with 5 treatments, namely A : AMF Glomus sp-3 + S. rolfsii; B: AMF Acaulospora sp + S. rolfsii; C: AMF Gigaspora sp + S. rolfsii; D: Combined AMF Glomus sp-3, Acaulospora sp, and Gigaspora sp + S. rolfsii; E: Without AMF + S. rolfsii (Control). Each treatment was repeated 5 times. The data were analyzed using Analysis of Variance (ANOVA) using the Statistix 8 program and the Least Significance Different (LSD) test at a 5% significance level. The results showed that the isolates of Acaulospora sp and Gigaspora sp were able to increase the resistance of peanut plants to stem rot disease (suppressing the incidence and severity of the disease) reaching 100%. Keywords: Arbuscular Mycorrhizal Fungi, indigenous, salicylic acid, Sclerotium rolfsii.

Abstract

Sidenuk rice is a superior rice variety produced by BATAN through a radiation mutation technique.             The new varieties that have been produced need to be supported by efforts to optimize production through fertilization technology. The purpose of this study was to determine the effect of organic fertilizer which can increase growth, production and reduce the use of urea fertilizer in lowland rice optimally. The study was conducted using a completely randomized design. Each was repeated 4 times so that the total experimental unit (pot) was 32 rice pots. The treatments include (1) Control (without urea fertilizer),              (2) Control (+) 100% urea, (3) 50% urea, (4) Local microorganisms (MOL), (5) Compost, (6) Biochar , (7) Azolla, (8) Mol + Compost + Biochar + Azola + SP 36 and KCl. The results showed that the highest grain weight was found in the 100% urea treatment, which was 43.97 g plant-1. MKBA treatment    (MOL fertilizer, compost, biochar, azolla) showed values that were not significantly different from 100% urea treatment. Organic fertilizer formula (MOL fertilizer, compost, biochar, azolla) can reduce the use of urea fertilizer by 50%.

Abstract

Shallots (Allium cepa var. Aggregatum L) have many varieties that can be grown in the highlands and lowlands and one of them is the Batu Ijo variety. Nutrients N and K play an important role for plant needs. This research was conducted from March to June 2019 in Medan Baru, Bengkulu City. This study used a completely randomized design with two factors. The first factor was the dose of N fertilizer and the second factor was the application of K fertilizer. The application of N fertilizer had a significant effect on the number of shallots at week 2. The Urea dose given decreases the number of spring onions. For the best treatment at plant height is the treatment of Urea 300 kg/ha and KCl 50 kg/ha. Plant growth from week 2 to 5 increased significantly. The application of K fertilizer has an effect on the number of shallots at week 2 and the number of tubers. The higher the plant age, the more the number of leaves produced, but at higher doses, the number of leaves and the number of tubers decreased. The best treatment for the number of leaves produced was Urea 300 kg/ha and without giving KCl. For the best treatment of fresh plant weight, namely Urea 300 kg/ha and KCl 150 kg/ha, the best treatment fresh tuber weight was Urea 300 kg/ha and KCl 150 kg/ha, for tuber diameter the best treatment was 200 kg/ha of urea and KCl 100 kg/ha and for the number of tubers of Urea 0 kg/ha and KCl 150 kg/ha.Keywords: shallots, N fertilizer, K fertilizer
