Abstract

Corn is a highly adaptable plant and can be cultivated in various soil fertility conditions.  Testing of corn varieties on hemic peat soils and while maintaining hydrological function is still very limited so that there is a void of information about corn varieties tolerant of toxic organic acids in hemic peat soils. The purpose of the experiment was to determine the growth, production and tolerance of corn varieties on hemic peat soils. The experiment was conducted using a complete randomized design by testing 4 varieties of corn namely Pioneer 23, NK 22, Bisi 18 and Pertiwi 3 repeated 5 times.  The experimental results showed that the Bisi 18 corn variety and Pertiwi 3 variety with production of 7.66 and 7.68 t ha-1 respectively.showed greater STI in hemik peat rice fields with high levels of toxic organic acids than STI Pioneer 23 variety and NK 22 variety with production of 7.48 and 7.53 t ha-1 respectively.

Abstract

Tanaman mint (Mentha piperita L.) merupakan tanaman daun aromatik bernilai ekonomi tinggi yang produktivitasnya berkaitan erat dengan pertumbuhan vegetatif dan ketersediaan nutrisi. Sistem hidroponik rakit apung memungkinkan pengelolaan nutrisi secara presisi, namun informasi mengenai konsentrasi nutrisi optimal untuk budidaya tanaman mint masih terbatas. Penelitian ini bertujuan mengevaluasi pengaruh berbagai konsentrasi nutrisi AB Mix terhadap pertumbuhan vegetatif dan biomassa tanaman mint yang dibudidayakan pada sistem hidroponik rakit apung. Penelitian disusun menggunakan Rancangan Acak Lengkap dengan lima taraf konsentrasi nutrisi AB Mix (100, 400, 700, 1000, dan 1300 ppm) dan lima ulangan. Parameter yang diamati meliputi luas daun, jumlah daun, jumlah cabang produktif, berat basah, dan berat kering tanaman. Hasil penelitian menunjukkan bahwa peningkatan konsentrasi nutrisi hingga tingkat optimum secara nyata meningkatkan pertumbuhan vegetatif dan akumulasi biomassa, sedangkan konsentrasi yang lebih tinggi tidak memberikan peningkatan tambahan. Jumlah cabang produktif tertinggi diperoleh pada konsentrasi 1000 ppm dan menurun pada konsentrasi yang lebih tinggi. Analisis korelasi menunjukkan adanya hubungan kuat antara jumlah daun dan biomassa segar, sedangkan luas daun dan jumlah cabang produktif berkontribusi nyata terhadap biomassa kering. Secara keseluruhan, konsentrasi nutrisi 1000 ppm direkomendasikan sebagai tingkat nutrisi yang optimal secara fisiologis untuk budidaya tanaman mint pada sistem hidroponik rakit apung.

Abstract

The purpose of this study is to determine the best concentration of benzyl amino purine (BAP) on the growth of durian seedlings (Durio zibethinus Murr.) grafted on the shoots of the durian kunik variety. This research was carried out from October 2024 to January 2025 at the main garden of the Agricultural Extension Center, Agriculture and Food Security Office, 2x11 Kayutanam District, Padang Pariaman Regency, West Sumatra. The design used was a one-factor Complete Random Design (RAL) with 5 levels of treatment. Each treatment was repeated 5 times. The observed variables were the percentage of live joints, the increase in the length of the entres, the increase in the height of the upper stem, the diameter of the rootstock, the increase in the diameter of the upper stem and the number of leaves. The result data was analyzed of variants at the 5% level and further tested at the DNMRT level of 5%. The results of the study on the concentration of BAP Benzyl Amino Purine) at a concentration of 400 ppm had a real effect on the success of grafting the shoots of Durian plants. Keywords: Durian, BAP, seedlings

Abstract

Penelitian bertujuan mendapatkan respon jagung hibrida diameliorasi fly ash batu bara dan kompos limbah tanaman jagung dilakukan di Nagari Lubuk Basung Kecamatan Lubuk Basung Kabupaten Agam dari Oktober 2025 – Januari 2026 dengan jenis tanah inceptisol. Percobaan dilakukan menggunakan rancangan acak lengkap faktorial dua faktor.  Faktor pertama adalah Fly ash batu bara dosis 0, 2, dan 4 t ha⁻¹ dan faktor kedua adalah kompos limbah tanaman jagung dosis 0, 5, dan 10 t ha⁻¹. Hasil percobaan menunjukkan 1) amelioran fly ash batu bara dengan kompos limbah tanaman jagung memperlihatkan interaksi terhadap laju tumbuh relatif, laju assimilasi bersih, umur berbunga jantan dan bobot tongkol per tanaman, 2) Fly Ash batu bara dosis 2 t ha-1  meningkatkan hasil jagung dengan produksi 7.07 t  ha-1, dan 3) kompos limbah tanaman jagung dosis 10 t ha-1. meningkatkan produksi jagung 7.07 t ha-1..

Abstract

The experiment was aimed to determine the most suitable method for selection of salt-tolerant, and to investigate the agronomic characteristics of salt-tolerant rice variety.  Two experiments were conducted to study the tolerance of 18 varieties to salt: 1) in situ screening of salt-tolerant varieties using completely randomized design, and 2) screening of salt-tolerant varieties using factorial experiment (varieties and salinity) with completely randomized design. The experiment showed that screening of rice variety that tolerant and sensitive to salt stress can be determined by comparing root dry weights in salt stressed condition and in unstressed condition, and in term of agronomical aspect, salt stress-tolerant rice showed good growth when planted in the saline field.   Key words: Screening, rice, swamp areas and salt stress

Abstract

Simpang Tanjung Nan Ampek Village, located in the Danau Kembar Subdistrict of Solok Regency, is one of the key potato-producing areas. Potato production in Solok Regency has reached 28,939 tonnes per hectare (BPS, 2023). To date, potato cultivation in this region has been heavily dependent on synthetic fertilisers and high levels of pesticide use, which can have detrimental effects on both biotic and abiotic components of the environment. One viable solution to mitigate these impacts is the application of local microorganisms, particularly Plant Growth-Promoting Rhizobacteria (PGPR), which are well-known for their ability to enhance nutrient availability, promote plant growth, and improve overall plant health. This community engagement programme aimed to increase farmers’ knowledge regarding the role of PGPR in enhancing potato growth and productivity. The activity was conducted in Simpang Tanjung Nan Ampek Village, Danau Kembar Subdistrict, Solok Regency, in February 2025. The programme employed three main methods: (1) socialisation activities to raise awareness of the functions and benefits of PGPR, (2) training sessions on PGPR propagation techniques, and (3) the practical application of PGPR on potato crops. The programme yielded positive outcomes. Farmers gained a better understanding of the benefits of PGPR, as well as the skills required for its propagation and application on potato plants. The educational and hands-on approaches used in the programme significantly improved the farmers’ knowledge and competence in implementing PGPR.
