Differences in soil types, water table regimes, and technological inputs in smallholder oil palm plantations on acid sulfate soil lead to the formation of distinct land units within the plantations. There are four different land units identified, each with its unique characteristics. These differences in characteristics result in variations in the properties and performance of oil palm plan…
Peat soil fertility is classified as low which is characterized by soil chemical properties, including low pH (acid), availability of macro (K, Ca, Mg, P) and micro (Cu, Zn, Mn, and Bo) nutrients, low cation exchange capacity (CEC) is high but Base Saturation (BS) is low. In increasing nutrient availability and absorption in plants, mycorrhizal materials are needed which can increase the ab…
This study aimed to evaluate the improvement in growth and yield of M8 generation mung bean plants (Vignaradiata L.) resulting from gamma ray mutation, in an effort to obtain plants with synchronous pod maturity characteristics and high pod weight production. The study employed a completely randomized design (CRD), involving a population of parent plants and 4 progenies, namely M8-18-3-1-6…
Green beans (Vigna radiata L.) is a plant that is widely cultivated in Kampar Regency, Riau. Mung bean productivity in Indonesia and the Kampar district tends to be stable every year, but mung bean farmers in the Kampar district generally cultivate green beans from the local Kampar strain which have low yield, have trichomes and pods that break easily. One of the efforts that can be made to…
Soil macrofauna measuring > 2 mm consists of milliapoda, isopods, insects, molluscs and earthworms (Maftu'ah et al., 2005). Soil macrofauna has an important role in the decomposition of soil organic matter in the provision of nutrients. Macrofauna will crumble dead vegetable matter, then the material will be excreted in the form of feces. The presence of soil macro, meso and microfauna has a ro…
Peatlands in Indonesia are widely used for the development of plantation crops, one of which is oil palm. The development of peatlands faces many obstacles, such as the reaction of acidic to very acidic peat soils with high cation exchange capacity (CEC) and the availability of nutrients in a bound form. These conditions do not support plant growth in general. The solution to solve the problem…
Oil palm is an important plantation commodity in Indonesia which has high productivity. The growth of oil palm is inseparable from disease disturbances. Oil palm stems base rot disease is caused by the fungus Ganoderma sp. Morphological identification determines the success of stem rot disease control efforts. Trichoderma sp. is a fungus that is antagonistic to Ganoderma. Trichoderma origi…
Acacia crassicarpa A.Cunn. ex Benth is a type of fast-growing tree species that is highly adaptable and tolerant of extremely environmental conditions. Acacia crassicarpa is a type of forest plant that has harvested period of approximately 5 years. Economically, the acacia is used as a wood source for processed into wood pulp, paper, and fuel potential for charcoal production. One of the e…
Corn (Zea mays L.) is one of the important staple food in Indonesia as carbohydrate and lipid sourse as well as raw material for various food industry. In addition to the source of human food, corn kernel is also utilized as the main component of animal feed industry. So in the last decades, the demand for corn in Indonesia increase from year to year. This research was conducted to determine th…
Moringa is an excellent plant that has been widely developed in Indonesia. One constraint in the moringa nursery is the snail (Achatina fulica Fer.) attack. Synthetic chemical pesticides that are mostly practiced give negative impacts on the environment. Therefore, alternative environmentally oriented pest control is critically required. Here, I used biopesticide extracted from forest betel…
Peat soil as agricultural land has various obstacles, one of the problems is the decrease in the groundwater level. Therefore, water management is an absolute necessity for agricultural activities on peatlands. Another effort to provide a good growing environment for corn plants can be supported by the application of organic mulch. The purpose of this study was to study the interaction betw…
Eucalyptus sp. is one of the plant developed as a wood fiber-producing industrial plantation forest in Indonesia. Xanthomonas sp. attack which causes Bacterial Leaf Blight (BLB) to be one of the obstacles to obtaining uniform seeds with good quality. Infected plants grow with many stems and are stunted compared to plants that are not infected. Thus, it is necessary to have an environmentally fr…
Eucalyptus pellita is one of the annual commodity species that is widely developed and utilized as a raw material for pulp and paper by Industrial Timber Plantation (HTI) companies in Indonesia, especially in dryland areas. The success of an HTI plantation starts with the availability of strong and healthy seedlings in the nursery. However, there are problems with plant pathogen attacks. O…
Bioherbicide from Eucalyptus pellita leaf extract can be used to control weeds in HTI plantations. One of which is Borreria alata (Aubl) DC. weed found in E. pellita HTI plantations. Borreria alata (Aubl) DC., is a broadleaf weed that frequently grows in E. pellita HTI plantations aged < 5 months, with a significant importance value index of 83.99%, indicating its high dominance compared to…
Management of specific primary macronutrients (N, P, and K) is essential to ensure the growth and development of Eucalyptus hybrid mother plants. This research was conducted at the R&D Nursery greenhouse and Soil Laboratory, Tualang District, Siak Regency. The objective of this study was to analyze the effect of specific primary macronutrients for the mini cutting production of three Eucal…
Mustard greens (Brassica juncea L.) is one of the broad leaf vegetable commodities that has the potential to be cultivated due to the high public demand for vegetables. The low production of mustard greens is caused by many factors, including pests and plant diseases. Important diseases of mustard greens are wet rot caused by Erwinia caratovora and black rot caused by Xanthomonas campestri…
Oil palm is a plantation crop that generates vegetable oil, which is in high demand in society. Due to the rising demand for vegetable oil, actions must be taken to increase palm oil production by replanting existing land rather than opening new oil palm plantation lands. Applying replanting in small plantations has the possibility of resulting in issues such as soil compaction and a lack o…
Peat soils have a low pH, high cation exchange capacity, low base saturation, and low nutrient content. One of the efforts in peat soil management is the addition of ameliorants such as Biochar. Biochar can improve soil fertility and absorb C, increase pH, increase nutrient availability, nutrient retention, and soil cation exchange capacity. The objectives of the study were to analyze the …
Soybean is one of the most popular agricultural commodities in Indonesia, but soybean production in Riau is still low, therefore it is necessary to make efforts to extend agriculture in the form of developing marginal land. This study aims to study and determine the interaction of Arbuscular Mycorrhizal Fungi (AMF) and coal fly ash (FA) zeolite and the main effect of each of these treatment…
