Abstract

Cayenne pepper (Capsicum frutescens L.) is one of the plants favored by the people of Indonesia. The production of cayenne pepper has increased but has not been able to meet the national demand for cayenne pepper, so the government still has to import it. This research aims to determine the effect of frequency of paclobutrazol and dose of NPK fertilizer on the growth and yield of cayenne pepper. The research was conducted in Gresik on November 2020 to March 2021.This research is a factorial experiment based on a Split Plot (RPT) consisting of 2 factors. The first factor is frequency of paclobutrazol (P) and second factor is dose of NPK fertilizer (N) and was repead 3 times. The combination between the frequency of paclobutrazol and dose of NPK fertilizer gave a significant effect on all parameters except the flowering age and fruit maturity. The combination of treatment without the application of paclobutrazol + 24 g/plant NPK 16-16-16 increased plant height by 18% and leaf number by 48% compared to control. The best result is combination of 2 times application of paclobutrazol + 24 g/plant on parameters number of flowers, fruitset, total number of fruits per plant, and total fruit weight per plant. The best results at the NPK dose of 24 g/plant were able to accelerate the flowering age (43.79) day and fruit maturity (86.04) day.

Abstract

Cayenne pepper (Capsicum frutescens L.) is one of the horticultural crops with high economic value. The production of cayenne pepper is often constrained by stem wilt disease caused by the fungus Fusarium sp. This research aims to know the effect of the consortium of Bacillus spp. and Pseudomonas fluorescens as biological agents to control fusarium wilt in cayenne pepper. This research was conducted at the screenhouse of UPN "Veteran" East Java. The research began in January 2021 until April 2021. The study was arranged using a Split Plot Design with two factors, namely antagonistic bacteria and application time and was repeated 4 times. The first factor is antagonistic bacteria with 5 levels of treatment, namely without the provision of antagonistic bacteria, Bacillus spp. isolate code Ba9, Bacillus spp. isolate code Ba17, P. fluorescens, Bacillus spp. isolate code Ba9 + P. fluorescens, Bacillus spp. isolate code Ba17 + P. fluorescens. The second factor is the application time with 2 levels of treatment, namely before transplanting seedlings and after transplanting seedlings. If it is known that there is a significant effect of the treatment, then the Duncan Multiple Range Test (DMRT) is carried out at the 5% level. The treatment of the consortium of Bacillus spp. isolate code Ba9 and P. fluorescens caused a delay in the incubation period of Fusarium sp. by 23.42%, increasing plant height by 20.55%, and accelerating the emergence of prospective flowers, while the treatment with the consortium of Bacillus spp. isolate code Ba17 and P. fluorescens suppressed the intensity of fusarium wilt disease by 29.03%, increasing the number of leaves by 56.58% compared to the single aplication of bacteria.

Abstract

Vertiminaponics is a combination of plant cultivation (hydroponics) and fish cultivation (aquaculture) in one place/land arranged vertically. In the vertiminaponic system, the planting medium plays an important role as one of the determinants of plant and fish growth. The purpose of this study was to find the best growing media for pakcoy growth and yield and catfish growth and yield in the vertiminaponic system. This study used a randomized block design (RBD) with one factor, namely the planting medium consisting of four levels, i.e. broken bricks, malang sand, gravel and zeolite. The results showed that the planting medium of malang sand produced the highest total dry weight (12.42 g) and total fresh weight of pakcoy (240.72 g). The zeolite growing media gave the highest weight of catfish in the vertiminaponic system (11.75 kg), but it was not significantly different from malang sand (11.03 kg).

Abstract

Cocoa is a plantation crop that has the potential to increase state income. In Bali, the highest cocoa production is in Jembrana Regency. Increasing the productivity of the cocoa plant can be achieve by using environmentally friendly fertilizer such as Arbuscular Mycorrhizal Fungi (AMF). The aim of this research is to obtain indigenous AMF isolates and their propagation with different planting media and water stress. The research was conducted from July to January 2021. Sampel AMF for islolation and identification was taken from Banjar Pangkung Medahan, Pulukan Village, Pekutatan District, Jembrana Regency, while isolation and identification of AMF was conducted at Agronomy and Horticulture Laboratory, Faculty of Agriculture, Udayana University, Laboratory of Plant Diseases, Laboratory of Genetic Resources and Molecular Biology of Udayana University and Greenhouse of Experimental Garden Faculty of Agriculture, Denpasar. This research used in propagating of spores of AMF was a Completely Randomized Design (CRD) with 2 factors and 4 replications. The first factor was planting medium which consisted of four treatment levels (soil planting medium, soil with sand growing media, soil with compost growing media, and sand with compost soil growing media) and the second factor was water stress which consisted of three treatment levels (ground water content of 100%, 70%, and 40% of field capacity). The results of isolation and identification showed that there were three genera of AMF spores found, i.e. Glomus, Gigaspora, Acaulospora. The results of spore propagation showed that soil and sand growing media with a combination of soil moisture content of 40% water field capacity produced the highest spores, which was 62 spores on average.

Abstract

Coffee is very important agro industry in Bali Province. The coffee center in Bali which is already famous for its geographic indication protection status is Kintamani District, which is the largest producer of Arabica coffee and an icon of Arabica coffee in Bali. Therefore, efforts are needed to maintain coffee production through the selection of fertilizers that do not harm the environment, for example biological fertilizers derived from arbuscular mycorrhizal fungi (AMF). This study aimed to find the best growing media composition and optimal soil water content and the interaction between the two treatments for endomycorrhizal spore propagation. This research was arranged in a completely randomized design (CRD) with 2 factors and 4 replications. The first factor was composition of growing media which consisted of four levels, i.e. Mt (soil only), Mp (soil and volcanic sand with ratio of 1:1/v:v), Mk (soil and compost with ratio of 1:1/v:v), and Mc (soil, volcanic sand, and compost with ratio of 1:1:1/v:v:v). The second factor was water stress which consisted of three levels, i.e. A0 (100% field capacity), A1 (70% field capacity), and A2 (40% field capacity). The highest spore multiplication results were obtained in the combination treatment of MpA0 as much as 55,00 spores with an increase of 120%. Meanwhile the combination treatment of MkA2 produced the lowest spores as much as 34.25 spores with an increase of 37%.

Abstract

Shallots (Allium cepa L.) are one of the leading vegetable commodities that have been intensively cultivated by farmers for a long time. A large percentage of damage to plants can result in reduced tuber weight. Study of insect diversity is the first step in pest control and pest management in crops. The purpose of this study, namely, to determine the diversity index of pests and natural enemies in shallot plantations after the use of biopesticide and chemical pesticide formulations. The research was carried out from December 2020 to February 2021. The study was conducted in Sukorejo Village, Rejoso District, Nganjuk Regency with an altitude of 140 m above sea level where fobio (biopesticide formulation) and chemical insecticides were applied. The area of the research area is about 140 m², where there are 2,400 shallot plant populations. This study used a non-factorial randomized block design (RAK) method. There were 4 treatments which were repeated 6 times to obtain 24 experimental units. Each experimental unit consisted of 100 shallot plants with a spacing of 18 x 14 m and a barrier distance of 50 cm. The results showed. Based on observations, the total number of arthropods found in shallot plantations in 5 observations was 1391 individuals consisting of seven orders of insects and one order of polypods. The highest diversity index was in treatment B (semi organic) because the combination of NPK fertilizer and spraying fobio on plants could increase insect diversity.
