Abstract

This study aims to evaluate the effect of various salinity levels on the growth and yield of four soybean varieties. The design used was a Completely Randomized Design (CRD) with a factorial pattern of two factors and two replications. The combination of treatments consisted of 32 experimental units, each consisting of 10 plants, so that the total number of plants observed was 320 plants. The first factor was the soybean variety consisting of four levels: V1 = Burangrang, V2 = Anjasmoro, V3 = Grobogan, and V4 = Detam 1. The second factor was the salinity level of the NaCl solution with four levels: S1 = 0 mg L?¹ (control), S2 = 1500 mg L?¹, S3 = 3000 mg L?¹, and S4 = 4500 mg L?¹. The parameters observed included plant height, shoot dry weight, number of branches per plant, number of pods per plant, number of filled pods, weight of 100 seeds, and tolerance index to salinity stress. The results showed that salinity stress had a significant effect on plant height and the number of filled pods. The treatment without salinity produced the highest total number of pods, number of filled pods, and weight of 100 seeds compared to other salinity treatments.

Abstract

Soybean (Glycine max (L.) Merrill) is a strategic crop requiring high-quality seeds to improve domestic production. However, soybean seeds have a limited storage life, especially at ambient temperature, which can reduce their physiological quality. This study aimed to identify the decline in seed quality during storage at room temperature. The experiment was conducted at the Agroecotechnology Laboratory, Universitas Andalas, using a Completely Randomized Design with two seed storage durations (3 and 6 months), each with four replications. Observed parameters included maximum germination potential, germination rate, vigor index, and germination uniformity. Results showed that seeds stored for 3 months maintained significantly higher physiological quality than those stored for 6 months. Maximum germination potential decreased from 85% to 25%, germination rate from 90% to 47%, vigor index from 47 to 6, and uniformity from 43% to 5%. It is concluded that soybean seed storage at ambient temperature should not exceed three months to preserve physiological quality. These findings provide important technical guidance for soybean seed management

Abstract

Tanah masam merupakan salah satu kendala utama dalam peningkatan produktivitas kedelai di wilayah tropis karena rendahnya ketersediaan hara dan tingginya toksisitas aluminium. Penelitian ini bertujuan untuk mengkaji variabilitas genetik, variabilitas fenotipik, dan heritabilitas arti luas beberapa karakter morfologis dan agronomis kedelai pada kondisi tanah masam (pH ±4,5), serta mengidentifikasi karakter seleksi potensial untuk pengembangan varietas adaptif. Percobaan dilaksanakan di Kecamatan Pulau Punjung, Kabupaten Dharmasraya, Sumatera Barat, menggunakan Rancangan Acak Kelompok dengan empat varietas kedelai (Grobogan, Dena 1, Deja 1, dan Dering 1) dan tiga ulangan. Pengamatan dilakukan terhadap karakter kualitatif dan kuantitatif tanaman. Hasil penelitian menunjukkan bahwa karakter kualitatif relatif stabil dan dikendalikan oleh gen mayor, sehingga tidak dipengaruhi secara nyata oleh kondisi tanah masam. Karakter kuantitatif menunjukkan respons yang beragam antar genotipe. Karakter pertumbuhan vegetatif, seperti tinggi tanaman dan jumlah cabang, memiliki variabilitas genetik dan heritabilitas rendah, menandakan dominasi pengaruh lingkungan. Sebaliknya, karakter komponen hasil, khususnya jumlah polong berisi per tanaman dan bobot 100 biji, menunjukkan variabilitas genetik dan heritabilitas tinggi, yang mengindikasikan kuatnya pengendalian genetik dan stabilitas ekspresi pada tanah masam. Dengan demikian, karakter komponen hasil berpotensi dijadikan kriteria seleksi utama dalam pemuliaan kedelai adaptif pada lahan masam. Kata kunci: Kedelai, Tanah masam, Variabilitas genetik, Heritabilitas, Seleksi varietas
