Abstract

The presence of weeds in immature oil palm plantations needs to be controlled, otherwise it results in competition with the main crop. Herbicide active ingredients, especially glyphosate, are widely used to reduce weed growth in oil palm plantations.. This study aimed to determine the dose of isopropylamine glyphosate herbicide that effectively controls weeds in oil palm plantations, changes in weed composition, and phytotoxicity due to the application of isopropylamine glyphosate herbicide in immature oil palm plantations. This trial was conducted in Oil Palm Plantation, Karang Anyar Village, Jati Agung District, South Lampung Regency and Weed Laboratory, Faculty of Agriculture, University of Lampung, September - December 2022. The trial was conducted using a randomized block design (RBD) with 4 replications and 6 treatments, namely several dose levels of isopropylamine glyphosate herbicide (787,5; 1.050; 1.312,5; and 1.575 g ha-1), mechanical weeding, and untreatment. Homogeneity of data variance was tested with Bartlett's test, additivity of data was tested with Tukey's test, and differences in treatment mean values were tested with the Least Significant Difference (LSD) test at the 5% level.The trial showed that isopropylamine glyphosate herbicide doses of 787,5 - 1.575 g ha-1 effectively controlled total weeds, grasses (Axonopus compressus and Ottochloa nodosa), and sedge (Cyperus kyllingia), as well as broad leaves (Asystasia gangetica and Melastoma affine) at dose levels of 1.312,5 and 1.575 g ha-1 at (4, 8, and 12) week after application, isopropylamine glyphosate herbicide doses of 787,5 - 1.575 g ha-1 caused changes in weed composition, and did not cause poisoning of immature oil palm plants after being applied to the crop disk until 12 week after application.

Abstract

Bulurejo Village is one of the villages in Gadingrejo Subdistrict, Pringsewu Regency, Lampung Province. Bulurejo Village has a quite active Women Farmer Group (Kelompok Wanita Tani/ KWT) known as ‘Ayu Tani’, which was formed in 2014 with 27 members. Bulurejo Village is one of the villages that has the potential to develop the cultivation program of potted vegetable plants (Tanaman Sayur Dalam Pot: TASAPOT). TASAPOT cultivation is conducted to increase the consumption of various food sources in the form of vegetables with the principles of being nutritious, balanced, diverse, and healthy, so that organic farming can be applied during a pandemic era with the aim of increasing body immunity. This community services program aims to equip the community of Bulurejo Village with theoretical and practical knowledges regarding the cultivation techniques of vegetable plants in pots. The method used includes extension, discussion, mentoring, and training or direct practice in the field based on the initial evaluation as a basis for determining the knowledge level of the target partner's regarding the cultivation techniques of TASAPOT. The implementation of this community services program has succeeded to achieve the expected outcomes, namely increased knowledge of the community and members of the 'Ayu Tani' KWT in Bulurejo Village about the importance of Sustainable Food Houses (Rumah Pangan Lestari: RPL) and the cultivation techniques of TASAPOT to improve family’s health the community's standard of living. In addition, there has been an increase in partners’ understanding of the cultivation techniques of TASAPOT, starting from the benefits of utilizing the house yard, the growing media used, planting techniques, and plant maintenance until harvest.

Abstract

A preliminary study of the reproductive responses of crystal guava plants under varying doses of paclobutrazol and NPK fertilizer was conducted. The research took place in a small-scale ‘Crystal’ orchard in Rajabasa 1, East Lampung, from August 2021 to March 2022. The study employed a 3x3 factorial randomized complete block design, examining two factors: paclobutrazol and NPK fertilizer. The first factor, paclobutrazol (P), had three levels: 0 ppm (control), 2000 ppm, and 4000 ppm. The second factor, NPK fertilizer, was tested at three levels: 0 g per plant (control), 250 g per plant, and 500 g per plant. The key variables measured were the number of reproductive shoots, blooming flowers, and fruits, serving as indicators of the ‘Crystal’ guava plant's reproductive responses. The study findings recommended the application of 2000 ppm paclobutrazol and 500 g per plant of NPK fertilizer due to their significantly positive impact on increasing the number of reproductive shoots, blooming flowers, and fruits. Notably, there was no significant interaction observed between paclobutrazol and NPK treatments in regulating plant reproductive growth.

Abstract

Atrazine 500 g/l is a selective herbicide that can be applied during pre- or post-growth of corn. This study aimed to determine the effective level of dosage in controlling weeds in the corn planting area and its impact on growth and corn yields. The study was conducted at the Experimental Garden of Universitas Lampung, South Lampung, and the Weed Laboratory of the Faculty of Agriculture, Universitas Lampung, from August to November 2022. The study used a Randomized Block Design (RBD) with seven treatments and four replications. The treatment consisted of 5 herbicide doses (Atrazine 500 g/l (500, 750, 1,000, 1,250, and 1,500 g/ha), manual weeding, and control. The results showed that Atrazine 500 g/l at doses of 750 - 1,500 g/ha effectively controlled the growth of total weeds, broadleaf and grass weeds, Digitaria ciliaris, and Richardia brasiliensis. While at doses of 500–1,500 g/ha, it effectively controlled Eleusine indica, Cleome rutidosperma, and Commelina benghalensis. Those doses did not poison, and did not inhibit growth, and the yield of maize.

Abstract

Penelitian ini bertujuan untuk mengetahui efektivitas herbisida isopropilamina glifosat dalam mengendalikan gulma di perkebunan kelapa sawit tanaman belum menghasilkan. Penelitian dilakukan di lahan budidaya kelapa sawit belum menghasilkan, di desa Karang Anyar, Lampung Selatan dari bulan Juni – September 2022. Penelitian ini terdiri dari 6 perlakuan yaitu 4 taraf dosis herbisida isopropilamina glifosat: 1.080 g/ha (P1), 1.440 g/ha (P2), 1.800 g/ha (P3), 2.160 g/ha (P4), penyiangan mekanis (P5), dan kontrol (P6). Perlakuan tersebut disusun dalam Rancangan Acak Kelompok (RAK) dengan 4 ulangan. Homogenitas ragam data diuji dengan uji Barlett, uji additivitas data diuji dengan menggunakan uji Tukey, jika asumsi terpenuhi maka data dianalisis ragam dan perbedaan nilai tengah perlakuan diuji dengan uji Beda Nyata Terkecil (BNT) taraf 5%. Hasil pengujian menunjukkan bahwa herbisida isopropilamina glifosat dengan dosis 1.080 – 2.160 g/ha efektif dalam mengendalikan pertumbuhan gulma total dari pertumbuhan gulma dominan, Borreria alata, Mikania micrantha, Praxelis clematidea, Axonopus compressus, dan Paspalum conjugatum hingga 12 MSA. Daya kendali terbaik pada gulma Axonopus compressus terdapat pada perlakuan isopropilamina glifosat dengan dosis 1.440 – 2.160 g/ha. Pengaplikasian herbisida isopropilamina glifosat dengan dosis 1.080 – 2.160 g/ha pada piringan tanaman kelapa sawit belum menghasilkan tidak menimbulkan gejala keracunan.
