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

This study aims to determine the effect of several immersion methods on dormancy breaking and methods that can accelerate dormancy breaking of Ciherang rice seeds. The experimental design used was a one-factor completely randomized design, namely the immersion method with 5 levels of treatments: the non-immersion method (P0), the immersion method using water at 30°C for 24 hours (P1), the immersion method using hot water with an initial temperature of 60°C for 24 hours. 24 hours (P2), the immersion method used a GA3 solution with a concentration of 0.5 ppm for 24 hours (P3), and the immersion method used a 3% KNO3 solution for 48 hours (P4) with five replications. The research was conducted at the Laboratory of Plant Breeding and Seed Technology, Faculty of Agriculture, Udayana University from September 2020 to November 2020. The results showed that the immersion method had a very significant effect on the germination variable (%), maximum growth potential (%), dormancy intensity (%), and speed of germination (%/etmal), and significantly affect the growth of seed fungus (%). P3 treatment was able to break the dormancy of rice seeds for 5 weeks of observation with the highest germination value (95.16%) and obtained the smallest dormancy intensity value (4.56%) better than P0 treatment without soaking (control) obtained a germination value of (7.76%) and the value of dormancy intensity (89.52%). The highest germination rate was obtained in treatments P3 and P4, which were (6.08%/etmal) and (3.35%/etmal, respectively).

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.

Abstract

Colletotrichum capsici is an important pathogenic fungus that causes anthracnose in red chili. One of the efforts to resolve this problem is by using biological agents of Bacillus spp. bacteria. This study aims to determine the potential of five isolates of Bacillus spp. bacteria. there are Ba-6, Ba-9, Ba-12, Ba-15, and Ba-17 in inhibiting the pathogen C. capsici. Laboratory research was conducted using a Completely Randomized Design with 4 replications. In vitro testing was carried out using a dual culture technique on PDA media and a detach fruit test on chili. The results shows that the best inhibition effectiveness of C. capsici by in vitro testing of PDA media, namely Bacillus sp. Ba-9 isolate with 23.04% inhibition. Furthermore, in the detachment test, Bacillus sp. Ba-9 isolate was able to suppress the growth of C. capsici by 21.25% compared to control.

Abstract

Eggplant (Solanum melongena L.) is a vegetable that is cultivated for its fruit in terms of nutrition and the price of eggplant is a commodity that is experiencing an increase in demand. This study aims to determine the age of transplanting and the best type of liquid organic fertilizer on the growth and yield of eggplant. This research was conducted in January-April 2021 in the experimental field of the Faculty of Agriculture, National Development University "Veteran" East Java. This study used a completely randomized design (RAL) with two factors, namely the age of transplanting and the type of liquid organic fertilizer with 16 treatment combinations repeated 3 times. The first factor is the age of transplanting with 4 levels, namely the age of seedlings 10 days, 20 days, 30 days, and 40 days. While the second factor is the type of liquid organic fertilizer with 4 levels of NPK fertilizer 20 grams/plant, banana weevil 150 ml/plant, Super Aci 3 ml/liter, and Nasa 150 ml/plant. The results showed that the age at transplanting and the type of liquid organic fertilizer showed an interaction on the observed parameters of the number of leaves and stem diameter. The age of transplanting 10 days and the type of NPK fertilizer 20 grams/plant showed the highest yield on the parameters of observing the number of leaves and stem diameter.

Abstract

Tomato is a type of horticultural commodity that is quite in demand by the people of Indonesia because of its high nutritional content. The aims of this research is to determine the effect of paclobutrazol concentration and dose of NPK fertilizer on the growth and yield of tomato plants. This research was conducted on the experimental garden of the Faculty of Agriculture, University of National Development "Veteran" East Java in December 2020 - March 2020 using polybags. This research is a factorial experiment based on a Randomized Complete Block Design (RCBD) consisting of two factors, the first factor is the concentration of paclobutrazol (P) consisting of: P0 = 0 ppm (control), P1 = 150 ppm, P2 = 300 ppm, P3 = 450 ppm and the second factor is dose of NPK fertilizer consisted of: N0 = 25 g/plant (control), N1 = 12,5 g/plant, N2 = 20 g/plant, N3 = 27,5 g/plant. The results showed that the combination of 150 ppm paclobutrazol + 27,5 g/plant of NPK fertilizer increased the number of flowers, total number of fruits, fruit weight per fruit, fruitset, and Vitamin C content.
