Abstract

Oil palm (Elaeis guineensis Jack) is an important plantation commodity for both agriculture and the economy, because its oil-producing potential is greater than that of other crops, such as corn, soybean and sunflower oil. The main disease of this plant is stem rot (BPB) caused by Ganoderma boninense. Therefore, it is necessary to know the incidence and severity of the disease as well as the control efforts that have been carried out at PTPN VIII Palm Oil Plantation, Cikasungka. The study used a Randomized Block Design with 3 observation blocks that had Ganoderma boninense attack each covering an area of 25 ha, each block taken 5 observation plots with an area of 50 x 50 m2 each (4 on the edge of the block and 1 in the middle of the block), then from each plot, 5 sub-plots measuring 10 x 10 m2 were taken (4 at the edges of the plot and 1 in the middle of the plot). Observational data were analyzed with variance and further tested by Duncan Multiple Range Test. The results of this study indicate that the symptoms of disease in the garden are very diverse, ranging from mild to very severe. The signs of the disease can be identified through the fruiting bodies of Ganoderma boninense. The incidence of disease in all survey locations ranged from 16 – 38%, where B3 was significantly different from B1. The lowest percentage of disease severity was in location B3 (5.75%) which was statistically significantly different from location B1. Location B1 had the highest disease severity, which was 23%. The control of BPB that has been carried out at the survey site includes the construction of isolation trenches followed by the application of biofungicides with the active ingredients of T. koningii and T. harzianum.

Abstract

White root rot disease (Rigidoporus lignosus) is one of the main diseases in rubber plants that can cause death the plants. Trichoderma sp. known as one of the biological control agents that capable of controlling the disease. This research aimed to identify the the potential of Trichoderma sp. isolates in controlling white root disease Rigidoporus lignosus in vitro. Trichoderma sp. isolates were isolated from 7 (seven) smallholder rubber plantations. The locations were Serdang Bedagai, Langkat, Simalungun, Labuhan Batu, Batubara, Asahan and Labuhan Batu districts. The seven Trichoderma sp. isolates were antagonized with Rigidoporus lignosus isolates from 4 (four) smallholder rubber plantations i.e from Serdang Bedagai, Langkat, Simalungun and Labuhan Batu districts. The antagonisme methods used dual culture on Potato Dextrose Agar (PDA) medium.The lowest inhibition zone in single treatment came from isolates from Simalungun district (TS) of 79.91% and the highest was isolate from Asahan district (TA) which was 91.82%. In combination treatment Trichoderma sp. isolate from Asahan (TA) could inhibit R. lignosus isolate from  Serdang Bedagai (JSB), Simalungun (JS) and Labuhan (JLB) 100%. Trichoderma sp. isolate from Batubara (TB) could inhibit R. lignosus isolate from  Langkat  (JL), Simalungun (JS) and Labuhan (JLB) 100%. All of Trichoderma sp. isolates had potential biological control agents, but in this research only both Trichoderma sp. isolates from Asahan (TA) and Batubara (TB) could inhibit most of the R. lignosus isolates in vitro.

Abstract

Oil palm phenology is a period of developmental phases of oil palm which is used to determine the development of oil palm, especially flowers, and fruit. Research on oil palm phenology on peatlands provides an overview of proper peat management and high productivity. The study aimed to get information on the growth phase and the development of oil palm time on peat land and the correlation with the environmental factor. The method used was the Marihat variety which was planted in 2002 on peat land and relatively maintained for the water table at 40-60 cm. The research was conducted from August 2017 until December 2020 on one of the oil palm plantation companies in Siak Regency, Riau Province. Direct observations related to plants' vegetative and generative phases were carried out, which were observed on 24 plant samples every seven days. The results showed that the monthly oil palm frond leaf increase averaged 1,8 fronds. The time needed from the appearance of 1st frond until an unknown flower appeared on average is 218 days. The length of the male flower phase from the unknown flower to the dry male flower is an average of 78 days. The female flower phase period from unknown flowers until the oil palm fruits have harvested an average of 226 days. The time it takes for oil palms on peat soil, from the appearance of the 1st fronds to the fruits, to be harvested is an average of 444 days. The sex ratio of the flower is not correlated with the rainfall, the number of rainy days, and the water table because the water table on the location is always maintained. Optimizing the water table is essential for managing oil palm productivity on peatlands.

Abstract

The study was conducted to determine the maximum delay of the proper drying time so that it does not affect the quality of rice seeds (Oryza sativa L. ) and can pass the quality testing of seed certification. This experiment used a Complete Randomized Design (CRD) using ten treatments and three replays; there were 30 experimental units. The results of the study were analyzed using ANOVA. Observations were made on the variables of moisture content before storage (%), moisture content after storage (%), germination (%), maximum growth potential (%), growing forging (%), plant height (cm), and numerous saplings. The results of the study showed no influence of the treatment of delayed drying time on the quality of rice seeds of the Inpari 42 variety. However, the moisture content increases with the long delay in drying time, germination power, maximum growing potential, and forging growth progressively decrease as the delay of drying time increases. The best results are obtained on the H0 treatment: the prospective seeds are immediately dried in the sun without storage after harvesting. The maximum drying time delay so that it can pass the seed quality test is six days after harvest. The delay in drying time does not affect the growth of the vegetative phase on the parameters of plant height and the number of saplings of 50 HSS.

Abstract

Dendrobium are one of the most cultivated ornamental orchids plants. However, orchids as genetic resources have not been optimally utilized as parents in crossing to produce offspring according to the characteristics desired by consumers. This study aims to study the similarities between the Hybrid results of crosses compared to their parent orchids and obtain a new variety of Hybrid from crosses of Dendrobium bigibbum and Dendrobium lineale. This research was conducted at the Bogor Botanical Gardens and Plosorejo Village, Matesih District, Karanganyar Regency, Central Java. The materials used were 14 samples of orchid plants, including three examples of D. bigibbum orchids, three samples of D. lineale orchids, four samples of Hybrid plants resulting from crosses of ♀ D. bigibbum X ♂ D. lineale, and four samples of Hybrid plants from crossing ♀ D. lineale X ♂ D. bigibbum. Observation variables include quantitative variables. The quantitative morphological variables use the guideline developed by BALITHI. To analyze the data using the program of NTSYSpc 2.02i version. The results showed that based on quantitative observations, Dendrobium lineale as a female parent can change the size of the dorsal sepal width, flower arrangement length, lateral sepal length, and flower length. And Dendrobium bigibbum as the female parent can change the size of the petal length, lateral sepal width, flower width, pseudobulb thickness, pseudobulb length, leaf length, and leaf width.

Abstract

The advantages of EPN (Entomopathogenic Nematodes) as a biological agens are it is safe for the environment, effective in controlling pests found above ground and underground in a relatively fast time, and can be easily propagated. EPN propagation is generally carried out in vivo, namely propagation using insect larva. The larvae that are often used are Tenebrio molitor, Galleria melonella, but these larvae are difficult to provide in large quantities. Therefore, it is necessary to find insect media that are cheap, easy to obtain and easy to use by farmers, one of which is Hermetia illucens larva and Alphitobius diaperinus larva. The study aimed to determine alternative host types for the production of entomopathogenic nematodes. The experiment used a completely randomized design (CRD) consisting of two factors. There were two tests carried out, namely a single test to determine the nematodes produced from each alternative host and a mortality test of T. molitor larvae. The concentration used for the single test was 200 JI/0.5 ml and was repeated 30 times. The mortality test for T. molitor larvae consisted of the first factor being the dose of EPN, namely 200 JI/ml, 400 JI/ml, 600 JI/ml, 800 JI/ml, and 1000 JI/ml. The second factor is the origin of NEP isolates from various agro-landscapes with 11 treatments repeated 3 times. Based on these several treatments, observations were made on the Lethal Concentration (LC) and the amount of JI production from each test insect. The highest EPN production is using T.molitor from Bangsal soybean isolate up to 4993,8 Juvenil, this production yield was higher than using larvae of A. diaperinus and H. illucens. the highest percentage of mortality in Bangsal soybean isolate with a concentration of 200 ji/ml up to 53.3%.

Abstract

Improving the productivity of shallots through the continuous application of inorganic fertilizers can result in decreased land productivity; one way to overcome further impacts that will arise from such use is through the provision of organic matter. The aim of this study was to determine the effect of planting media and ecoenzyme treatment on shallot production. This study used a factorial randomized block design which consisted of 2 treatment factors, namely first factor was Planting Media (M) consisting of M0: 100% topsoil, M1: topsoil (75%) + chicken manure compost (25%), M2: topsoil (50%) + chicken manure compost (50% and M3: topsoil (25%) + chicken manure compost (75%). The second factor was Ecoenzyme (E) which consists of 0, 10, 20 and 30ml. Plant observations included wet tuber weight per plot (g), dry bulb weight per plot (g) and tuber diameter (mm). Data analysis method was analysis of variance and further test for real treatment using Duncan’s multiple Range Test. The results obtained that the provision of planting media in the form of 75% topsoil + 25% compost was able to respond to the production of shallots. Ecoenzyme and the interaction between ecoenzyme in the growing media gave an insignificant effect on the production of shallots as wet tuber weight per plot, dry bulb weight per plot and tuber diameter.

Abstract

Shallot (Allium ascalonicum L.)  is a plant species sensitive to environmental conditions. Although, Shallot can grow optimally in the dry season, in the rainy season the production of Shallot tends to decrease. Efforts made by farmers to overcome this are by increasing the dose of inorganic fertilizers. If it continues, it will have a negative impact on the environment. The application of Plant Growth Promoting Rhizobacteria (PGPR) and cow manure has increased the production of shallots grown out of season. This study used the basic pattern of 3x3 factorial Completely Randomized Block Design (RCBD) and was repeated 3 times. The first factor was the PGPR concentration of Belulang's roots which consisted of 3 levels, namely P0: 0 ml/L, P1: 10 ml/L, P2: 20 ml/L. Factor 2 doses of cow manure consisting of 3 levels, namely N0: 0 tons/ha, N1: 10 tons/ha, N2: 20 tons/ha. Further test using Duncan's Multiple Distance Test at 5% level. The results showed that there was no interaction between the two treatments, but separately the two treatments had an effect on the growth and yield of shallots. a concentration of 10 ml/L PGPR of belulang's roots and cow manure at a dose of 20 tons/ha is a good treatment to be recommended in this study.

Abstract

Indonesia has experienced a decline in green bean production due to unsuitable green bean cultivation and low soil fertility. However, combining NPK Mutiara and organic fertilizer made from active maja fruit containing NPK Mg and Fe can increase soil fertility and quality in an environmentally friendly way. This study aims to examine the effect of combining organic fertilizers with active ingredients of maja fruit and pearl NPK in increasing the growth of green bean varieties of VIMA-1. The research was carried out in Sukajadi Village, Perbaungan, Serdang Bedagai District, from October to December 2021 using a 2-factor RAK design where the first factor was PO application with four treatment levels, namely M0 = Control; M1 = 100ml PO: 750 ml water; M2 = 100 ml PO: 1500 ml water; M3 = 100 ml PO: 2250 ml water. Then the second factor is the dose of NPK Mutiara fertilizer where P1 = 30g/plot and P2 = 40g/plot with the number of replications 3. The results showed that the administration of PO with the active ingredient of maja fruit had an insignificant effect on all parameters observed. However, the NPK fertilizer treatment had a significant impact on diameter. Stems at treatment P1 = 30g/plot.

Abstract

The study understood the influence of giving rabbit manure ordure to nitrogen uptake, growth, and yield of pakcoy and how to judge the effect of different doses of rabbit manure on nitrogen uptake, growth, and yield of pakcoy plants. The survey was conducted in October-November 2021. The method used was a non-factorial Block Design of Randomized. The factor consisted of 6 dose levels which were repeated four times. The element was the provision of rabbit manure to pakcoy plants, composed of 6 groups of rabbit manure fertilizer doses. K0 = 0 Kg/ha, K1 = 2500 kg per hectare K2 = 5000 Kg per hectare, K3 = 7500 Kg per hectare, K4 = 10000 Kg per hectare and K5 = 12500 Kg per hectare. The results showed that all observed variables were affected: plant height, leaf number, and leaf area at the age of 27 days after planting. Each K3 variable has better growth and yields, like fresh plant weight and total N uptake. K3 treatment had the best results but was not significantly different from K2, K4, and K5.
