Avocado is a fruit crop that is commercial and potential to be widely cultivated. Market demand for avocado was increased so production of avocado seed must increase too by grafting. The problem of grafting is often found in the connection between scion and rootstock that showed like elephant foot phenomenon, so it was necessary to study the linkage process between scion and rootstock. This research leads up to an increased percentage of finished graft seedlings that were ready for planting in the field. This method used a factorial experiment consisting of 2 factors. The first factor was the stages of entres (flushing, endodormancy, and ecodormancy), and the second factor was the grafting method (cleft graft, wedge graft, and splice graft). The research design used Complete Randomized Design with 4 replications and ANOVA with BNJ 5% test. The results showed all observations parameters interacted. Stage ecodormancy in splice graft resulted of vascular tissue (xylem and phloem) between scion and rootstock recovered better than other combination treatments by producing the best-grafted avocado seedlings growth with an increased percentage of grafted seedling by 42.50%, an interval of flushing by 4.91 days, and increased frequency of flushing by 1.83 times compared to stage flushing in cleft graft.

Orchids are one of the most important ornamental plants in the world. The existence of natural orchids in their habitat is approaching extinction rate, so it is necessary to increase the diversity of orchids by crossing them. The Vanda orchid is one of the famous orchids in Indonesia because of its uniqueness. Vanda orchids have a very abundant diversity, so they can increase the potential of orchid plants. This study used a hybrid orchid plant Vanda celebica x Vanda dearei irradiated by Gamma-rays with a dose of 0 Gray, 10 Gray, 20 Gray, 30 Gray, 40 Gray, and 50 Gray. The data obtained from the observations will be analyzed using descriptive methods by observing each plant in various doses of Gamma-ray radiation compared with control treatment and presented in the form of boxplot images. The irradiation dose of hybrid Vanda orchids (Vanda celebica x Vanda dearei) increased the diversity in the parameters of plant height and leaf width. The application of a dose of Gamma-ray irradiation did not cause a significant interaction with the variable number of leaves. The diversity value decreased in the parameters of leaf length and number of roots. Application doses of Gamma-ray irradiation of 10, 20, and 30 Gray can change the leaves into grooves compared to control plants. Mutant plants had lower chlorophyll content than control plants (0 Gray).
兰花是世界上最重要的观赏植物之一。天然兰花在其栖息地的生存濒临灭绝，因此有必要通过杂交来增加兰花的多样性。万达兰因其独特性而成为印度尼西亚著名的兰花之一。万达兰具有非常丰富的多样性，因此它们可以增加兰花植物的潜力。本研究使用的是一种杂交兰花Vanda celebica x Vanda dearei，其辐射剂量分别为0 Gray、10 Gray、20 Gray、30 Gray、40 Gray和50 Gray。从观察中获得的数据将使用描述性方法进行分析，通过观察不同剂量的伽马射线辐射下的每个植物与对照处理进行比较，并以箱线图图像的形式呈现。杂交万达兰(Vanda celebica x Vanda dearei)的辐照剂量增加了其株高和叶宽参数的多样性。施加一定剂量的伽马射线辐照对叶片数量的变化没有造成显著的相互作用。多样性值在叶长和根数参数上呈下降趋势。与对照植物相比，应用剂量为10、20和30 Gray的伽马射线照射可以使叶子变成凹槽。突变植株叶绿素含量低于对照植株(0 Gray)。

Hypothenemus hampei (Ferrari) (Coleoptera: Scolytidae) or Coffee Berry Borer (CBB) is the most destructive major pest that causes quantitative and qualitative losses in Arabica coffee. The research aimed to calculate population, attack H. hampei, coffee yield losses, the measure distribution pattern of H. hampei on various Gayo arabica coffee varieties, and the analyze estimated decrease in the production of coffee based on population and attack H. hampei in Gayo arabica coffee. The location chosen as a place of observation and sampling is a smallholder coffee plantation with variations in elevation. Each area is determined by two points of observation and sampling locations. At each sampling location, 80 ripe or red coffees were taken, 80 dark or yellow coffees, and 80 young or green coffees (24 pieces per four branches per tree). The results showed that the population and attack of CBB pests on Gayo 3 varieties are relatively high compared to Gayo 1 and Gayo 2 varieties. The distribution pattern of CBB on all varieties of Gayo Arabica coffee showed an aggregated distribution based on population and attack. The decrease in arabica coffee production has the potential to occur on a variety Gayo 3.

Twisted disease is one of the important diseases that can decrease shallot yield.The purpose of this experiment was to examine the effect of the interaction Trichoderma harzianum and nano silica on twisted disease and shallot yield. The research was conducted in Platar, Mangunjiwan, Demak and the Laboratory of Ecology and Plant Production, Faculty of Animal and Agriculture Science, Undip, on April – Agustus 2022. The experimental design used factorial completely randomized design with three replications. The first factor was T. harzianum consisted of three levels (P0 = 0 (control), P1 = 10, and P2 = 20 g plant-1). The second factor was nano silica concentration with four levels (S0 = 0, S1 = 1000, S2 = 2000, and S3 = 3000 ppm). The results showed that application of T. harzianum 20 g plant-1 or nano silica 3000 ppm had the lowest disease intensity 2,74 % and 2,48 % observed at 20 days after planting and 11,81 % and 10,81 % observed at 40 DAP. Combination T. harzianum 20 g plant-1 and nano silica 3000 ppm resulted in the highest yield parameters which were tuber diameter (2,370 cm), number of tubers (6 tubers), tuber fresh weight (36,2 g), and tuber dry weight (28,7 g). Treatments of T. harzianum and nano silica did not significantly affect the infection rate and number of leaves, but application of T. harzianum 20 g plant-1 and nano silica 3000 ppm showed a decrease in twisted disease intensity and the highest shallot yield.

Chili consumption in Indonesia has increased. Efforts to increase chili production need fertilization through roots and leaf fertilization. The research aimed to obtain optimum intervals of NPK (nitrogen, phosphor, potassium) fertilization and kinds of foliar fertilizer for the growth and yield of chili. The research was conducted from April to August 2020 in Gayam Village, Sukoharjo Regency, Central Java, Indonesia. This study used an experiential method with a Randomized Complete Block Design (RCBD) of 2 factors. The first factor was an interval of NPK fertilization (16-16-16) with a concentration of 25 g.L-1 with a dose of 240 mL.plant-1. The interval of NPK fertilization consists of 4 levels, NPK fertilizer which was applied every 5, 10, 15, and 21 days. The second factor was foliar fertilizer which consists of A foliar fertilizer, B foliar fertilizer, and C foliar fertilizer. The results showed that the interval of NPK fertilizer affected the number of dichotomous branches, dry stove weight, cumulative fruit, cumulative fruit weight, and fruit length at 1st harvest. NPK fertilization every 15 days increased the dichotomous branches by 23.16%, dry stove weight by 37.98%, cumulative fruits by 37.41%, and cumulative fruit weight by 41.46%. B foliar fertilizer and A foliar fertilizer gave the same performance in dichotomous branches. There was no interaction effect between the interval of NPK fertilization and the kind of foliar fertilizer on all growth and yield variables. NPK fertilization optimum intervals as supplementary fertilizers should be given every 15 days. This research can be used as a reference for farmers in fertilizing chilies.

Various fruit flies are in Indonesia, but only a few species of fruit flies have been found at the red guava plant in Deli Serdang District. Knowing the species of fruit flies are needed to do the proper control. In addition to morphological identification, it is necessary to carry out molecular characterization to obtain accurate results in characterizing species differences. This study aims to identify the fruit fly based on morphology and molecularly PCR-RAPD for mapping the genetic closeness of the relationship between individual fruit flies. Bactrocera morphologically identified at LIPI, namely B. carambolae, B. papayae, B. caudata, B. albistrigata, B. umbrosa, B. curcubitae, B. tau, and B. kinabalu. For molecular identification PCR-RAPD, shows the dendrogram results from the Neighbor-Joining analysis based on RAPD markers of DNA band characters showing the genetic proximity of eight species divided into three groups of Bactrocera based on their location. The closeness of genetic relationships between individuals was analyzed using Pairwise Distance Calculation which describes the genetic distance between species. The results of Pairwise Distance Calculation ranged from 0.13-0.42. By knowing what species there fruit flies are in red guava plantations in the Deli Serdang district, it can make it easier for farmers to monitor and control fruit flies in red guava plantations.

The success of durian pollination in nature is very low (<5%) due to high self-incompatibility in durian flowers. Artificial cross-pollination is an alternative method that can be used to increase the successful pollination of durian. So, information on the pollen viability of the durian flower and the time of artificial cross-pollination accurate and effective is required. This research aimed to examine the pollen viability of the durian varieties of Montong and Sitokong varieties at three different times and to determine the success rate of artificial cross-pollination between both varieties at three different times. This research was carried out at the Morpoyan Seed Center and the Genetic and Breeding Laboratory of the Faculty of Agriculture, UIN Suska Riau. Pollen viability testing used the staining method. Artificial cross-pollination between the Montong durian and the Sitokong durian was carried out reciprocally at three different times (11.00–13.00, 15.00–17.00, and 19.00–21.00). The total number of flowers crossed was 300. The results of this study showed that the percentage of pollen viability of Montong durian at 11.00–13.00, 15.00–17.00, and 19.00–21.00 was 94.91, 97.67, and 97.23%, respectively. While the pollen viability of Sitokong durian was 93.33% at 11.00–13.00, 94.45% at 15.00–17.00, and 94.76% at 19.00–21.00. The successful rate of crosses of durian Montong (♀) x Sitokong (♂) at 11.00–13.00, 15.00–17.00, and 19.00–21.00, respectively were 46, 26, and 34%, while the percentage of success of durian Sitokong crosses (♀) x Montong (♂) is 48% at 11.00–13.00, 54% at 15.00–17.00, and 22% at 19.00–21.00. Successful artificial cross-pollination between Montong and Sitokong durian or vice versa was higher at 11.00–13.00 compared to other times. The results of this study can be utilized to formulate the timing of artificial cross-pollination of durian in the future.

The productivity of red ginger in Indonesia has decreased by 9,174 tons compared to 2017. The decrease is due to the very limited area of red ginger production, the method of red ginger cultivation, which is still very conventional, and the low amount of organic matter in the soil. This study examines the effect of planting media composition on the growth and production of red ginger. The study used a Completely Randomized Block Design (RCBD) with six treatments, namely control (soil without manure), cow manure: green manure: soil (1:1:1), P2 = goat manure: green manure: soil (1:1:1), green manure: soil (1:2), cow manure: soil (1:2), and goat manure: soil (1:2) and repeated four times. Composition media of goat manure: green fertilizer: soil with a ratio of 1:1:1 could increase the growth of red ginger in variable plant height, number of leaves in the clump, leaf area, and the weight of fresh stover with a yield of 52.7 cm; 10,75; 148,5; 2952.59 cm2; and 307.33 g. Composition of green fertilizer media: soil with a ratio of 1:2 could increase the weight of dry stover with a value of 39.32 g, and red ginger production includes fresh weight of rhizomes 111.32 g, storage weight of rhizomes 107.87 g, and rhizome volume 124.12 cm3.

Biochar is a carbon-rich solid material made by pyrolyzing agricultural residual biomass, and it decomposes much more slowly than the biomass from which it is made. Biochar has been shown to have agronomic benefits. Biochar can provide agronomic benefits for a longer period due to its persistence in the soil. The purpose of this research is to gather evidence demonstrating that biochar has a longer effect on increasing aerobic rice productivity. A pot experiment was carried out in UNINUS. The treatments were as follows: control, 20 Mg rice husk biochar (RHB), 40 Mg RHB, 50 Mg RHB, 60 Mg RHB, 10 Mg RHB + 10 Mg composted poultry litter (CPL).ha-1, 20 Mg RHB + 20 Mg CPL.ha-1, 30 Mg RHB + 30 Mg CPL.ha-1, and 30 Mg RHB + 30 Mg CPL.ha-1. Treatments were started in September 2018, and the effects were measured from February to June 2019. The findings revealed that rice husk biochar and its combination with CPL increased aerobic rice growth (plant height, number of tillers, and yield). The most effective combination rate is the application of biochar and composted poultry litter, 20 Mg RHB + 20 Mg CPL.ha-1, because it significantly extended the residual effect. The combined application increased rice productivity when compared to a single application of biochar and composted poultry. The residual effect of biochar and composted poultry litter on rice productivity was superior to fresh application.

Salt stress and infrequent watering application obstruct sweet basil growth and yield. But both condition can increase flavonoid production. The aim of this research is to get tolerant level of sweet basil plant on various salt concentration and watering frequency with several parameters consists of growth, yields, and flavonoid contents. The research was conducted from October 2021-January 2022 at the greenhouse of Petahunan Village, Pasuruan City. The method used was a factorial of randomized block design with various watering frequency consisist of once a day (W0), once on two days (W1), and once on three days (W2). Various salt concentration consists of 0 ppm (N0), 1000 ppm (N1), 2000 ppm (N2), 3000 ppm (N3), and 4000 ppm (N4). There is an interaction between saline medium and infrequence watering, whenever with more watering can decrease saline effect on plant primary metabolism. Interaction betweet saline medium and infrequence watering inhibit plant vegetative growth. But saline that interaction can improve sweet basil yields such us flowers, seeds, and also flavonoid contents on leaves. The research conclusion is that interaction between saline medium and infrequence watering obstructed vegetative growth, but increase yields and flavonoid contents.
