Abstract

Chili is one type of vegetable that is often cultivated by farmers because of its high economic value and high nutritional value. Anthracnose (Colletotrichum spp.) is the main disease that often attacks large chili plants which can cause yield loss and destroy all cultivated plants. This study aims to determine the effect of the plant refugia kenikir (Cosmos caudatus) combined with plant spacing to avoid anthracnose disease. The method used was a factorial randomized block design (RAKF) with 2 factors, Refugia kenikir (C. caudatus) (R) and Planting Distance (J), there were 6 treatments and 4 groups so that there were 24 experimental units with each unit planted 4 plants, so we got 96 plants. Which was tested by observing the percentage of disease incidence and wet weight of fruit. The results showed that refugia kenikir (C. caudatus) plant spacing combination had no significant effect on the incidence of anthracnose disease, but the spacing treatment did affect the wet weight of fruit observed on days 105 and 120 with the highest average production in treatment J3R1 (60x120 cm). ; 60 kenikir trees) of 63.5 grams and 91.25 grams.

Abstract

Eggplant (Solanum melongena L.) The demand for eggplant was increasing, but the availability of eggplant is low so it cannot be fulfilled. One of the causes of low eggplant production is due to the attack of wilt disease on eggplant plants caused by Fusarium oxysporum. Symptoms include wilted leaves, yellowing leaves and brown root and stem tissue. Control that is often done is to use pesticides (fungicides) which can cause environmental pollution. One control of Fusarium spp. wilt disease. with microbial antagonists. This research was conducted to determine the ability of isolates of rhizobacteria Pseudomonas fluorescens group (PF) and Bacillus spp. from bamboo, chili and ferns inhibited the growth of Fusarium spp. in vitro. Completely Randomized Design (CRD) with isolates of Pseudomonas fluorescens group and Bacillus spp. each 4 treatments, control. Testing the inhibitory power of isolates of Pseudomonas fluorescens group and Bacillus spp. carried out by the challenge method and in vitro. Observations were made on the percentage of inhibition of rhizosphere bacteria (DH) after incubation for 7 days. All isolates of Pseudomonas fluorescens group and isolates of Bacillus spp. Has different inhibitory power on the fungus Fusarium spp. The isolates of Pseudomonas fluorescens group derived from bamboo roots from the Palem area (KPBP) (81.95%) were isolates that had the highest percentage of inhibition and Bacillus spp. derived from chili roots from the Guntung Manggis area (BGTP1) (70%) was the isolate that had the highest percentage of inhibition.

Abstract

The productivity of mustard (Brassica juncea L.) in Indonesia has increased in 2015-2018, in line with the increasing demand for this vegetable. One of the obstacles in the cultivation of mustard is the attack of leaf destroying pests. An alternative solution to control pests is to use natural ingredients from the galam plant (Melaleuca cajuputi Roxb.). The purpose of this study was to examine the effect of galam leaf insecticide to suppress leaf destroying pests on mustard plants. The study used fresh galam leaf extract as the main ingredient in the manufacture of vegetable insecticides, which were applied in various doses. The research place in a vegetable plantation, Guntung Payung Village, North Loktabat District, Banjarbaru and was carried out for 40 days from seeding to harvesting. This study used an experimental method with a one-factor Completely Randomized Design (CRD) consisting of 5 concentration treatments and 2 controls with 4 replications. The results showed a very significant effect on the intensity of pest attack on the 4th observation. The intensity of the attack of mustard leaf destroying pests from the highest to the lowest was shown by water control (K) treatment of 26.6%, galam leaf extract 10% ( G5) 21.3%, Galam leaf extract 6% (G3) 20.5%, Galam leaf extract 8% (G4) 17.7%, Galam leaf extract 2% (G1) 15.3%, Galam leaf extract 4 % (G2) 14.2% and Chemical control (M) 7.9%.

Abstract

Soybean production in Indonesia still relatively low, even though the demand for soybean in every year has increased with increasing growth population, however the demand for soybeans is unable to balance domestic production, so it must be imported in a huge amount (Ohorella, 2011). To increase soybean production is certainly not always dependent in using of chemicals, by using suitable plant spacing can reduce the growth of pests naturally, natural enemies of pests also play a role in suppressing the growth of pests, therefore it is necessary to set different of plant spacing to knowing the best spacing for suppresing pests naturally. The purpose of this research was to determine the types of pests and natural enemies in the generative period of soybean plants and to determine the effect of different spacing on pest and natural enemies diversity. This research use Randomized Block Design (RAK) 1 Factor with 5 types of treatment spacing (20 x 20 cm, 20 x 30 cm, 20 x 40 cm, 20 x 50 and 20 x 60 cm) and 5 replications so that there are 25 experimental units. The results showed that plant spacing significantly affected pest diversity, but did not significantly affect the diversity of natural enemies, in this research, the best plant spacing to suppress pest growth was treatment with a spacing of 20 x 30 cm.

Abstract

This study observed the spacing effect on arthropod diversity in soybean from November 2017 to January 2018. The treatments were arranged in a randomized block design, with five replications and five different spacings: A - 20x20 cm, B - 20x30 cm, C - 20x40 cm, D 20x50 cm, and E - 20x60 cm. The highest arthropods were found at the narrowest spacing (20x 20 cm) and the lowest at the broadest spacing (20x60 cm). Soybean plantations in the study area had a medium category for diversity index (H'), a fairly even category for evenness index (E), and a low category for dominance index (D). All types of relative index values did not differ between treatments.
