Abstract

The presence of weeds is a significant factor that contributes to the decline in maize yield. To reduce yield loss, appropriate weed control methods must be applied. The first step in determining these methods is to identify weed dominance and diversity. This study aims to identify the dominance and diversity of weeds in three corn planting systems: conventional, jajar legowo 1:2, and 1:3 spacing. The research was conducted at the Teaching Farm Polinela Organic Farm in Lampung Province from November to December 2023. Vegetation analysis was performed using a 0.5 m2 quadrant randomly placed on 10 plots of land. The dominance value of weeds was determined using the Summed Dominance Ratio (SDR) value, while the diversity of weeds was measured using the Shanon-Wiener index value (H'). The study found that the conventional field had 9 weed species, the 1:2 legowo field had 8 weed species, and the 1:3 legowo field had 5 weed species. Ageratum conyzoides was the dominant broadleaf weed species in both the conventional corn field and jajar legowo 1:2, while Asystasia gangetica dominated the jajar legowo 1:3 corn field. The weed diversity index analysis results for the three corn planting systems fall into the medium category. Specifically, the results are 2.12 for conventional corn fields, 1.94 for 1:2 jajar legowo corn fields, and 1.3 for 1:3 jajar legowo corn fields.

Abstract

One of the obstacles in rubber plant cultivation is the presence of weeds. Weeds reduce the quantity and quality of yields, interfere with the maintenance and harvesting process, and become hosts for pests and plant diseases. This study aims to determine the diversity and dominance of weeds in smallholder rubber plantations. The research was conducted in two locations of smallholder rubber plantations in Juni-Juli 2023. The first location was in Natar, South Lampung and the second location was in Negeri Katon, Pesawaran. Sample selection was done by purposive sampling method with 4 replicates. The results showed that in the Natar location there were 13 weed species, while in the Negeri Katon location there were 14 weed species. Three weed species that dominated in the two locations were Axonopus compressus, Asystasia gangetica, and Ottochloa nodosa. The A. compressus weed had the highest SDR in both locations at 20.23% in the Natar location and 18.79% in the Negeri Katon location. The results of this study can be used as a basis for determining appropriate weed control techniques.

Abstract

Pengendalian gulma secara mekanis melalui sistem olah tanah yang tepat mampu menekan pertumbuhan gulma dan meminimalisir penggunaan herbisida kimiawi. Namun, sistem pengolahan tanah yang tidak tepat dapat menyebabkan terangkatnya biji dan propagul gulma yang sudah lama dorman dalam tanah naik ke atas permukaan tanah, sehingga menjadi viable untuk berkecambah dan memperbanyak diri. Faktor lain pemacu pertumbuhan gulma adalah tersedianya unsur hara yang cukup dalam tanah. Penelitian ini bertujuan untuk mengetahui pengaruh sistem olah tanah dan residu pupuk N jangka panjang tahun ke-34 setelah 2 tahun pemberaan lahan terhadap keanekaragaman vegetasi dan simpanan biji gulma dalam rangka merumuskan strategi pengendalian gulma. Penelitian dilaksanakan di Politeknik Negeri Lampung, terdiri dari dua faktor: sistem olah tanah (olah tanah intensif, olah tanah minimum, dan tanpa olah tanah) dan residu pupuk N (0, 100, dan 200 kg/ha. Pada Tahap 1, analisis difokuskan pada vegetasi gulma di atas permukaan tanah, sedangkan pada Tahap 2, penelitian meneliti simpanan benih gulma pada kedalaman tanah 20 cm. Hasil penelitian menunjukkan bahwa sistem olah tanah minimum tanpa residu pupuk nitrogen dan tanpa olah tanah dengan residu N 100 kg/ha pada tahun 2021, mampu menekan pertumbuhan gulma hingga tahun 2024. Residu pupuk N pada lahan yang telah diberakan selama dua tahun tidak berpengaruh terhadap keanekaragaman vegetasi gulma. Integrasi berbagai strategi pengelolaan gulma dapat mengurangi dampak negatif kehadiran gulma di pertanian. Petani dapat mengadopsi teknologi pengolahan tanah konservasi dan pertanian presisi untuk meningkatkan keberlanjutan dan efisiensi.

Abstract

One of the determinants of the success of an oil palm cultivation business is the provision of quality seeds. Seedlings can be produced through good maintenance. Oil palm nurseries are divided into two stages: the pre-nursery phase lasts 3 months after germination, and the main-nursery phase lasts  7-9 months after pre-nursery. In uncertain weather like today, it is very difficult to predict environmental conditions that are suitable for oil palm seedlings. Meanwhile, in the main nursery phase, the seeds are placed in an open area with adjusted planting distances. One alternative to reduce evaporation and save water is by providing several types of organic mulch. This research aims to determine the effectiveness of using various types of organic mulch in enhancing the growth of oil palm plants in the main nursery during the dry season. This research used a randomised block design with four treatments, including no mulch (control), empty palm fruit bunch mulch, straw, and reed. Each treatment uses a weight of 50 grams of mulch per plant in a polybag. Based on the results and discussion, it was found that using organic mulch could increase plant height, number of leaves, stem diameter, soil moisture and soil organic C content. However, the use of mulch does not affect soil pH.

Abstract

This study investigates the efficacy of liquid organic fertilizers (POC) derived from goat and cow manure as environmentally friendly alternatives for enhancing oil palm seedling growth. Conducted at the Oil Palm Nursery Unit of Politeknik Negeri Lampung (January–June 2024), the experiment employed a factorial randomized block design. Two factors were tested: POC from goat manure (0, 100, and 200 ml per seedling) and POC from cow manure (same levels). Growth parameters observed included seedling height, stem diameter, leaf count, leaf chlorophyll content, and leaflet area. Data were analyzed using ANOVA at a 5% significance level, followed by Least Significant Difference tests for mean comparison where applicable. Results show that goat manure POC at 200 ml per seedling significantly improved seedling height, leaf count, and chlorophyll content, while cow manure POC at the same dose enhanced height, stem diameter, and leaf number most effectively. No significant interaction effect between goat and cow manure treatments on any growth parameter was observed. These findings suggest that both goat and cow manure-derived liquid organic fertilizers, applied at 200 ml per seedling biweekly, can optimally support early growth of oil palm seedlings. However, their combined application did not yield synergistic benefits. The use of these organic fertilizers offers a sustainable alternative to conventional synthetic fertilizers and may contribute to improved nursery management practices in oil palm cultivation.

Abstract

In Indonesia, the most commonly cultivated type of coffee is Robusta coffee. Robusta coffee is a polyclonal plant, so its production can be increased by planting several superior clones in an area. One way to increase Robusta coffee production is by planting several superior clones in one area, because Robusta coffee is a polyclonal plant. The research was conducted by identifying the morphological characteristics of Robusta coffee. This is to see the relationship between Robusta coffee clones that have not been certified and clones that have been certified. The goals of this research were: 1) to knowing the morphology differences of Robusta coffee clones; 2) to knowing the proximity of Robusta coffee clone classes that have not been certified to those that have been certified; 3) Get a new clone of Robusta coffee. The research was conducted in a coffee plantation in Muara Baru, Kebun Tebu, West Lampung, Lampung. A Randomized Block Design (RBD) was used in this study and grouped by repetition. Observation of coffee morphological characters was carried out based on International Plant Genetic Resources Institute (IPGRI) coffee descriptor guidelines.. Morphological relationships are presented in the form of dendograms which are analyzed using the single link method. The results showed differences in the morphology of Robusta coffee clones. The Parabola clone has a different plant appearance from other clones, such as: large stems, large and long branches resembling a parabola. The Korolla 1, Korolla 3, Korolla 4, Sidokayo and Bagio clones have rounded and full flower buds. There is a relationship between certified and uncertified clones, namely the Sidokayo clone and Korolla 1 clone, the Tugu Sari clone and Sidokayo clone with Korolla 1 clone, and the Parabola clone with Korolla 4 clone. The Bagio clone has no affinity with any clone, so it can become new superior clone.

Abstract

Tanggamus Regency has a large potential for plantation resources. More than 85% of its land is classified as suitable for cocoa cultivation. Optimizing this potential requires the use of superior cocoa clones with pod morphological characteristics that support high productivity. This study aims to determine the quantitative pod morphological characteristics of 5 cocoa clones and identify the most suitable clones for cultivation in Suka Agung Village, Bulok District, Tanggamus Regency. The research method is a survey with a purposive sampling method. Quantitative pod morphological data were analyzed using ANOVA and DMRT at a significance level of 5%. The results showed that MCC 01 and MCC 02 showed better quantitative characteristics than other clones. This was indicated by higher average pod diameter, number of seeds per pod, seed length, seed diameter, and number of seeds per 100 g. However, the MCC 01 clone is considered to have moderate resistance to Vascular Streak Dieback (VSD) and Cocoa Pod Borer (CPB). In conclusion, MCC 02 is suitable for cocoa cultivation in Suka Agung Village, Lumbok District, Tanggamus.
