Abstract

Crop of corn (Zea mays L.) is seed crop which be used developed nations as staple food after rice. Pest activatir of cob of Heliothis armigera Hubner represents one of the corn crop pest which destroys many corn fruit especially at young fruit. The progress of technology has found a way to eradicate H. armigera biologically buy using a certain organism which is formulated in the form of pesticides. One of the product is Bactospeine WP which contains of active materials of Bacillus thuringiensis Berliner. The purpose of this research is to know the percentage of death symptom influenced by Bactospeine WP as stomach poison to some larva H. armigera at various given concentration. The research is conducted on laboratory. The research method used is Complete Random Device (CRD) with two factors and four times repetition. The first factor is concetration with three levels and second factor is larva instar with four levels. Perception is conducted on 1st, 2nd, 3rd, 4th and 5th day after treatment. Result of research indicates that death of larva H. armigera can be influenced by different of concetration of Bactospeine WP and instar larva.

Abstract

Peronosclerospora spp. is one of the problems in the cultivation of maize in Indonesia. Damage caused by the fungus Peronosclerospora spp. can reach 90-100% especially in susceptible varieties. Abiotic environmental conditions such as low temperatures and high humidity accompanied by a layer of water on the leaf surface can increase the occurrence of disease. Disease management techniques are still dominated by the application of synthetic fungicides that have several negative impacts, such as killing non-target organisms, increasing pathogen resistance and environmental pollution. However, these impacts can be suppressed through monitoring activities that play a key role in integrated disease management programs. Monitoring activities facilitate the process of epidemiological analysis through a mathematical model approach so that it can be known patterns of development of plant diseases and the rate of infection as a basis in developing disease management strategies. Therefore, it is necessary to conduct research on disease development models ranging from maize varieties in the improvement of maize plants in Mojokerto Regency. The results showed a model that was able to represent the development of downy mildew in Mojokerto was monit. The highest infection rate was on land using P35 variety from other land using NK 6172 variety.

Abstract

Downy mildew is a major disease in maize plants in Indonesia. It was reported that yield losses due to downy mildew ranged from 50%-80% in some areas of maize production center. Efforts are made to control downy mildew disease by conducting tillage, crop rotation, intercropping, use of fungicides, and irrigation affect the development of downy mildew. Therefore, efforts to deterimine the most effective control of downy mildew need to be carried out more extensive research, one of which is by looking at the downy mildew development models based on different cultivation variables that aim to find out the variables that influence the high and low incidence of downy mildew in Mojokerto. the results show that the model that is able to represent the development of downy mildew in Mojokerto was monomolecular. The incidence of the disease using varieties P35, NK 7328, NK 6172, NK 212 shows the category of mild attacks and varieties of Bisi 18 shows the category moderate attacks. Tillage is a way of cultivation that influences the low incidence and infection rate of downy mildew in Puri, Mojokerto.

Abstract

Palm oil (Elaeis quineensis Jacq) is one of the mainstay commodity crops of non-oil and gas foreign exchange resources for Indonesia. Palm oil flowers emit volatile compounds that can invite insects. The types of insects that visit oil palm flowers vary, not all visit the flowers are able to act as pollinators. This research aimed to study the diversity of oil palm flower insects so that the information obtained could be useful for subsequent conservation activities. Identification carried out up to morphospecies level. The purposive sampling method used to determine the sample plants used to observed the diversity of visitors. Based on observations of diversity in oil palm flowers obtained 16 morphospecies in order of the number of populations namely E. kamerunicus, Gelechiidae sp. 01, Chelisoches sp. Rhabdoscelus sp, Forficula sp, Velinus nigrigenu, Salticidae sp. 1, Formicinae sp.1, Tirathaba sp, Rhinocoris fuscipes, Thrips hawaiiensis, Formicinae sp.2, Metisa sp, Tetragnathide sp. 1, Thomisidae sp. 1, Euchantecona sp. with a dominance index of 0.89, a diversity index of 0.33 and an evenness index of 0.12, which is relatively low.

Abstract

Increasing production of cayenne plant commodities can be done easily and cheaply, enough to do with the selection of varieties and appropriate cultivation techniques, one of which is the time of pruning. The purpose of this study was to determine the growth and yield of three varieties of cayenne pepper due to the time of shoot pruning. This research was conducted in the UPT greenhouse for Food Crops and Horticulture Agribusiness Development East Java, Sidoarjo in February-June 2019. This research was a factorial experiment prepared using a Completely Randomized Design (CRD) consisting of two factors and repeated three times. The first factor is the time of shoot topping with four levels of treatment, including without topping, topping 7 HST, 14 HST and 21 HST. The second factor is variety with three levels, namely, Mhanu F1 variety, CR ASA 7 and OR Kencana. Observation parameters included plant height, number of leaves, number of productive branches, number of flowers, number of fruits per harvest period, total number of fruits, fruit set, fresh fruit weight per harvest period and total fresh fruit weight. The combination treatment of P3V3 produced the highest total number of fruits (102,33 fruits) and the heaviest total fresh fruit weight (288.10 g), significantly different from all treatments. The treatment of shoot trimming time significantly affected all observation parameters. The use of three varieties significantly affected the parameters of plant height, number of flowers, number of fruit plants per harvest and weight of fresh fruit plants per harvest
