Abstract

The purpose of this research is to investigate the impact of application of manure on soybean yield on cocopeat and in order to get the appropriate dose for the soybean crop. Research was done using Completely Randomized Design (CRD) which consists of 4 treatments and 3 replications. There are 12 unit of experiments with composition: A = control (without fertilizer), B = cocopeat + 100 g manure / polybag and C = cocopeat + 200 g manure / polybag, cocopeat + 300 g manure / polybag. The research revealed that the application of manure can increase the soybean yield on cocopeat

Abstract

Penelitian penggunaan berbagai macam Legum Cover Crop (LCC) dalammenyerap logam-logam berat pada lahan bekas tambang emas di kabupatensijunjung. Tujuan penelitian adalah untuk melihat LCC yang paling bagus dalammenyerap logam-logam berat pada lahan bekas tambang emas. Penelitian inidilakukan di Nagari Pala Luar Kecamatan Koto Tujuh Kabupaten Sijunjungselama 3 bulan dan dilanjutkan dengan analisis di Laboratorium Tanah FakultasPertanian Universitas Andalas. Rancangan yang digunakan dalam penelitian iniadalah Rancangan Acak Kelompok (RAK) 5x3 dengan 5 perlakuan dan 3ulangan, perlakuan penggunaan tanaman LCC dimana, A=Kontrol (tanpa LCC), B = Mucuna conchinchinensis, C = Calopogonium mucunoide, D = Centrocemapubescen, E = Mucuna bracteata. Data analisis dengan menggunakan tabelAnova 5% apabila F hitung lebih hitung lebih dari F tabel 5 % dan uji lanjut BNJ5%. Dari hasil penelitian tersebut dapat disimpulkan bahwa penggunaan LCCjenis Mucuna bracteata mampu menyerap logam berat lebih banyak dibandingkan jenis LCC lainnya.Kata Kunci : LCC, Logam-logam berat, lahan bekas tambang

Abstract

Abstract: Leading sectors play a vital role in driving the economic growth of a region. Lima Puluh Kota Regency possesses several leading plantation commodities, including cocoa, areca nut, tobacco, coconut, cinnamon, clove, gambier, robusta coffee, and sugar palm. The COVID-19 pandemic has affected the economy, including the plantation sector. This study aims to examine the production trends of these leading plantation commodities in Lima Puluh Kota Regency. The research employs a descriptive method by analyzing the annual growth rate of production. The highest recorded production growth rates were: cocoa at 161.6% in 2024, areca nut at 28% in 2022, tobacco at 93.1% in 2020, coconut at 29.2% in 2021, cinnamon at 26.2% in 2021, clove at 170.6% in 2024, gambier at 115.8% in 2023, robusta coffee at 17% in 2022, and sugar palm at 38.6% in 2024. Keyword: plantation; production. Abstrak: Sektor unggulan memiliki peranan penting untuk mendorong pertumbuhan ekonomi suatu daerah. Kabupaten Lima Puluh Kota memiliki komoditas perkebunan yang menjadi unggulan, yaitu kakao, pinang, tembakau, kelapa, kulit manis, cengkeh, gambir, kopi robusta, dan enau. Adanya pandemi covid-19 berpengaruh terhadap perekonomian termasuk juga sektor perkebunan. Tujuan penelitian melihat perkembangan produksi komoditas perkebunan unggulan Kabupaten Lima Puluh Kota. Metode yang digunakan yaitu metode deskriptif yang menjelaskan analisis pertumbuhan produksi tahunan (Annual Growth Rate). Pertumbuhan produksi tertinggi kakao sebesar 161,6 % pada tahun 2024, pinang sebesar 28 % pada tahun 2022, tembakau sebesar 93,1 % pada tahun 2020, kelapa sebesar 29,2 % pada tahun 2021, kulit manis sebesar 26,2% pada tahun 2021, cengkeh sebesar 170,6 % pada tahun 2024, gambir sebesar 115,8 % pada tahun 2023, kopi robusta sebesar 17 % pada tahun 2022, enau sebesar 38,6 % pada tahun 2024. Kata kunci: perkebunan;produksi.

Abstract

Coffee is an important agricultural commodity with increasing global demand, so optimizing the growth of coffee seedlings, especially during the seedling phase, is crucial to increase productivity. The use of natural plant growth regulators offers an environmentally friendly and economical solution. This study aims to evaluate the effect of natural plant growth regulators from onion extract and bean sprout extract on the growth of robusta coffee seedlings (Coffea canephora L.) during the seedling phase. The study was conducted using a Randomized Block Design (RBD) with three treatments, namely control, onion extract, and bean sprout extract. The parameters measured included plant height, stem diameter, and number of leaves for six weeks. Data were analyzed using ANOVA and BNT test at the 5% level. The results showed that both natural plant growth regulators significantly increased the growth of coffee seedlings compared to the control. Bean sprout extract gave the best results for plant height (16.75 cm), while onion extract was superior in increasing stem diameter (4.65 mm) and number of leaves (12.20). Statistical analysis confirmed significant differences between treatments and controls for all parameters. Thus, the use of onion and bean sprout extracts as natural growth regulators has proven effective in increasing the growth of coffee seedlings in the seedling phase, offering an environmentally friendly and economical alternative for optimizing the growth of coffee seedlings.

Abstract

This research aims to see the effect of the number of leaves left on the rootstock and the best defoliation time to improve the performance of cacao shoot connection seedlings. The research was conducted in the experimental garden of Politeknik Pertanian Negeri Payakumbuh from March to July 2023. Cocoa clone ICS was used as rootstock and clone TSH as scion. The experimental design was 4x4 factorial with 3 replications, the environmental design was completely randomized design. Data were analyzed statistically using F test and DNMRT further test at 5% level. From the research and data processing, it was found that there is an interaction between the treatment of different number of rootstock leaves and different defoliation times on the performance of cocoa shoot grafting seedlings based on the variables of percentage of grafted seedlings, number of shoots, number of leaves, leaf area and weight of seedling scion. It can be concluded that defoliation of the rootstock six days before splicing with rootstock having four leaves produces the best performance of cacao shoot grafting seedlings
