“…La variabilidad en la intensidad y duración de las lluvias, afecta la producción de fruta y calidad del aceite (Abubakar et al, 2022). Para Indonesia, a través de un simulador llamado "Agricultural Production Systems sIMulator (APSIM)" estimaron el crecimiento de plantación del cultivo (Akram et al, 2022). Los resultados sugieren que para una plantación de 0 a 8 años, se requieren entre 2500 mm y 3900 mm de riego anual, necesidades de riego que a largo plazo pueden afectar los niveles freáticos de diversas regiones tropicales del mundo, es más, el problema de la falta de riego puede ser mayor, ya que las estimaciones no toman en cuenta las necesidades de riego para la producción de fruta fresca (Akram et al, 2022;Subramaniam et al, 2020).…”

Introducción. La palma de aceite (Elaeis guineensis) es uno de los monocultivos perennes que se ha extendido a casi un poco más de diecinueve millones de hectáreas en el mundo, su expansión ha generado debate social, económico y político en diversos países tropicales. Una de las problemáticas que se ha discutido, es el impacto sobre las propiedades fisicoquímicas, biológicas y ecológicas del suelo. Objetivo. (i) Ofrecer un panorama actual de la expansión del cultivo de palma de aceite para una zona de la región Soconusco, Chiapas, México, (ii) documentar los efectos que provoca la palma de aceite sobre las propiedades fisicoquímicas y biológicas del suelo y (iii) presentar algunas propuestas de prácticas de manejo para incrementar la fertilidad y la abundancia de macroinvertebrados del suelo. Desarrollo. Se realizó la búsqueda de palabras clave en el apartado de “tópicos” dentro de la base de datos “Web of Science” del año 2009 hasta marzo del 2018. Se consultaron investigaciones que relacionan el cultivo de la palma de aceite con los parámetros físicos, químicos y biológicos del suelo. La literatura demuestra los efectos negativos que genera el monocultivo de palma de aceite sobre algunas propiedades fisicoquímicas del suelo y sobre la ecología y biología de la macrofauna edáfica. Conclusión. Se muestra evidencia de que el mal manejo del monocultivo de la palma de aceite tiene implicaciones ambientales. La integración de buenas prácticas de manejo sostenibles, podrían mitigar los daños al suelo.

“…The oil palm plantations are currently facing an important issue of the limited availability of land resources with suitable characteristics to support optimum growth and production. Therefore, these plantations are eventually developed on marginal lands, such as sandy and peat soils [3]. Indonesia has about 7.5 million Ha of land with cultivable marginal soils.…”

Preference of pollination insect Elaeidobius kamerunicus Faust. to the female inflorescence of oil palms influenced by volatile organic compounds (VOCs) emitted from the receptive flowers. VOCs, one factor of the pollination process, need more intensive research to escalate the production value of oil palm, such as fruit set. However, some cases occur in the suboptimal area where pollination is un-optimal. This research aims to study the E. kamerunicus preferences for different VOCs composition from female inflorescence on clay, sandy, and peat soil type. This study used a modified olfactometer as the test equipment. The extraction VOCs of female inflorescence on three different soil types used the maceration method and was analyzed by Gas Chromatography and Mass Spectrometry (GC-MS) instrument. The percentage of attraction E. kamerunicus preference to female inflorescence on clay, sandy, and peat soil types were 40%, 33%, and 24%. GC-MS analysis results showed that VOCs were only detected on clay soil types with a content of 1.11%, known as an attractant, namely Benzene, 1-methoxy-4 (2-Propenyl). It can affect the variation of preference of E. kamerunicus to the female inflorescence.

“…Each seedling aged 0 -9 months requires 0.1 -0.25 liters of water for each watering which is done 2x a day, in the morning and evening. For seedlings aged [4][5][6]. In this case, it is necessary to pay attention to the state of rainfall so that additional watering can be given as needed [1].…”

“…Rainfall is the amount of rainwater that falls in a specific time and area. Rainfall is measured in daily, monthly, and yearly times [4,6]. A rain gauge is a tool for measuring rainfall in an area, whether rural, sub-district, or province, which refers to WMO (World Metrological Organization) standards.…”

Watering is a very important thing at the plant nursery stage. Without proper watering, the growth of the seedlings will be disrupted. In the process of watering must pay attention to several things, such as watering time and water discharge. At this time, most independent smallholders do not understand how to use a rain gauge or what is often called an ombrometer. These farmers prefer to use the old way of looking at the state of the soil in the watering process rather than using an ombrometer. In this case, as we know, buying an ombrometer is quite expensive. An ombrometer is a rain gauge which is also often referred to as a rain gauge. This tool is installed in an open place without protection or shade so that rainwater will be caught directly by this tool. The unit used is millimeters with an accuracy of reading up to 0.1 mm. Currently, practical rain gauges that are self-made without using factory machines are still not validated. The purpose of this research is to the results of simple ombrometer (C) accuracy and precision tests compared to Observatory Ombrometers, Ordinary Ombrometers, and Automatic Weather Stations (AWS). The location of the research test was in the oil palm nursery area at the Research and Experimental Garden of the Yogyakarta Community Plantation Academy. Rainfall data were obtained from Nine Practical Rain Gauges (C), Observatory-type Ombrometers (A), Ordinary Ombrometers (B), and Automatic Weather Station (AWS). Statistical methods are used to test accuracy and precision. The results of the C test compared to AWS have a precision value of 95.9% and an accuracy of 88.7%. Comparison of C with A shows a precision value of 99.6% and an accuracy value of 98.3%. The results of testing C against B show a precision value of 99.5% and an accuracy of 97.5%.
