Abstract

Chili is one of the most valuable horticultural commodities, yet production is declining year after year. Fruit fly pests, which cause losses of 30-60%, are a stumbling block to growing chili production. Several types of aromatic vegetable extracts were used in this investigation, including clove leaves, babadotan, citronella leaves, and basil leaves, all of which have been found to contain methyl eugenol components. The goals of this study were to find the most efficient form of aromatic vegetable extract for usage as a fruit fly pest attractant and to see how different aromatic vegetable extracts affected the intensity of fruit fly pests.  The treatments were set up in a completely random order and were repeated three times. Planting chilies, creating aromatic vegetable extracts, making traps, deploying traps in the field, estimating the number of trapped fruit fly populations, and finally assessing the results were all part of this study. P1 = clove leaf extract, P2 = babadotan leaf extract, P3 = citronella leaf extract, and P4 = basil leaf extract are the therapies that will be provided. Bactrocera dorsalis was identified as the captured fruit fly species. The clove leaf extract treatment had the most fruit flies captured (35.67), while the babadotan leaf extract had the least (29.76), but none of the treatments were substantially different

Abstract

Productivity of superior genotypes often did not satisfyingly achieve its genetic yield potential. Interaction between genetics and environmental factors more likely to driven the final yield of the varieties. The concept of balanced fertilization is carried out by referring to the creation of a balance of macro-nutrients in the soil so that plants can produce optimally. The research was conducted in a form of experimental study at Tarowang village, Takalar Regency during growing season of 2021 from May to September 2021. A split plot design was used with fertilization package as the main plot and superior varieties as subplots. Three fertilization packages combined inorganic and organic fertilizer were used, namely fertilization package consisted of N: P: K with ratio of 225:100:75, fertilizer package that consisted of N: P: K ratio of 200:100:50 + KNO3 25 kg + Biotani 5cc L-1, and fertilizer package that consisted of N: P: K with a ratio of 200:100:50 + KNO3 25 kg + Ecofarming 5cc L-1. Six superior varieties used were Nasa 29, JH-37, Bisi 2, Bisi 18, SINHAS 1 and NK7328. Based on the level of both factors, 18 treatment combinations were obtained and repeated three times. Responses of maize varieties to fertilization packages, consisted of different combination and dosage of NPK fertilizers, KNO3 and organic fertilizers, were varied between varieties. The treatment of fertilization package of N: P: K = 225:100:75 with Bisi 2 variety gave the highest maize productivity, namely 12.39ton ha-1

Abstract

Aphis gossypii Glover is one of important insect pest in Indonesia. Genetic analysis of resistance to A. gossypii is required in plant breeding program to obtain host-plant resistance cultivar. Diallel analysis was used to estimate genetic parameters for chili pepper resistance to A. gossypii infestation in early generation. The objective of this research was to estimate genetic parameters of chili pepper resistance to A. gossypii infestation with diallel crossing design. The F1 and parent plants were arranged in randomized competed block design with three replication. Resistance lines was measured using choice test laboratory screening techniques. Two aphids were infested per plant and stopped 12 days after first infestation. Different lines respond was detected as shown by significant numbers of aphid per leaf, total aphid per plant, and total winged aphid per plant. There were no maternal effect and resistance were controlled by recessive and polygenic genes. Gene effects for resistance to aphid’s infestation were additive and dominance. Dominance effect larger than additive effects. Broad-sense heritability values were high but narrow-sense heritability values were very low

Abstract

Effort to increase rubber plant production should be done, especially rejuvenation for old rubber plant which in turn require high numbers of seedling within short time period. One of the method to provide rubber plant seedlings within short time period is through grafting technique which combine plant having strong rootas base stem and high production plant as upper stem (entres). The objective of this research was to study response of entres age and clone to growth of rubber seedling (Hevea brasiliensis Muell, Arg.) produced from green and brown grafting. This study was conducted from February 2019 to Februari 2020. This study used Factorial Randomized Block Design with entres age as the first factor consisting of 3, 6, 9, 12 and 15 months as well as clone as the second factor consisting of PB 260 and BPM 24. Data was analyzed by using analysis of variance and followed bywith Honestly Significant Different (HSD) test and regression analysis. The study results showed that the best treatment was entres having 9 months of age as indicated by grafting success, the speed of stum out, stumlength, stumdry weight, root length androot dry weight which had the highest values than that of other treatments. Clone of PB 260 was the best entres that was very compatible with base stem of GT1 clone than that of BPM 24 clone because it gave the highest yield in term of all observed parametes. The interaction between 9 month entres age and PB 260 clone was the best treatment
