Kacang Nagara dibudidayakan pada lahan rawa lebak Kalimantan Selatan, terutama di Kecamatan Daha Utara dan Kecamatan Daha Selatan. Penanaman dilakukan pada saat air surut bulan Juni hingga September. Mengingat hingga sampai saat ini petani menggunakan benih produksi sendiri, tentunya muncul permasalahan utama yaitu mutu benih semakin menurun. Benih bermutu dapat mengalami penurunan kualitas akibat penyimpanan kurang tepat atau benih telah melewati masa simpan. Penurunan mutu pada benih dapat diatasi melalui biopriming. Biopriming merupakan inkubasi larutan perlakuan pada benih menggunakan mikroorganisme dipadukan bahan organik. Tujuan dari penelitian ini yaitu untuk mengetahui pengaruh biopriming larutan taoge dan Trichoderma spp. terhadap viabilitas dan vigor benih kacang Nagara. Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) Faktorial dengan 2 faktor dan 3 kali ulangan sehingga terdapat 36 satuan percobaan. Faktor pertama terdiri dari konsentrasi larutan taoge (k) dengan 4 taraf yaitu akuades (k0), larutan taoge 5% (k1), larutan taoge 10% (k2), dan larutan taoge 15% (k3). Faktor kedua yaitu jenis Trichoderma (t) dengan 3 taraf terdiri dari tanpa Trichoderma (t0), T. harzianum (t1), dan T. viride (t2). Metode UKDdp (Uji Kertas Digulung dalam plastik) dengan setiap gulungan berisi 50 benih kacang Nagara varietas Padi. Hasil penelitian menunjukkan bahwa biopriming larutan taoge dan Trichoderma spp. berpengaruh nyata terhadap variabel daya berkecambah benih kacang Nagara lewat masa simpan, akan tetapi pada variabel potensi tumbuh maksimum, indeks vigor, keserempakan tumbuh dan kecepatan tumbuh hanya faktor tunggal yang berpengaruh. Peningkatan tertinggi pada setiap variabel yaitu perlakuan larutan taoge 10% dan T. harzianum (k2t1).

Rice production in South Kalimantan during January to September 2020 decreased compared to 2019. The use of rice seeds per hectare is generally still not in accordance with the recommendations. The local varieties of rice seeds that cultivated are from last year's cropping season, where storage was not good which could lead to a decrease in seed quality. Shallots contain hormones auxin and gibberellins, can be used as a natural growth regulator. This study used a solution of shallots on three local varieties of rice seeds. The purpose of this study was to provide information on the use of natural growth regulators in shallot solution as an alternative to increase seed viability to become a provider of quality seeds. This research carried out from October to November 2021 at the Production Laboratory of the Department of Agroecotechnology, Faculty of Agriculture, Lambung Mangkurat University. The implementation of the research is making shallot stock solution, seed preparation, seed soaking, seed germination, and maintenance. The method used was qualitative using single factor Completely Randomized Design with three levels of treatment and each treatment consisted of five replications. The results showed that treatment using onion solution invigoration had a significant effects on the parameters of growth uniformity and maximum growth potential of expired local rice seeds of Siam Banjar variety. The highest growth speed and seed germination were found in Siam Saba variety. The highest growth uniformity was found in Siam Unus variety. The highest maximum growth potential is found in Siam Mutiara variety.

Rice as a food source that provides carbohydrates for the people of Indonesia, especially South Kalimantan, needs to be increased in production so that the community's needs can be met. The quality of seeds will determine the productivity and quality of seeds. Storage treatment is one way that can be done to maintain seeds until the seeds are planted, but storage treatment that is too long will cause seed deterioration or seed viability to decrease. The decline in seed quality caused by keeping in open spaces storage causes fluctuations in temperature and humidity due to direct interaction with the environment. Efforts to control factors that can affect the rate of seed deterioration can be executed, among others, by using an impermeable storage container. Impermeable storage containers do not support the exchange of air from the environment to the inside of the storage container. The purpose of this study was to determine which type of impermeable storage container is best for the quality of rice seeds. The research has been at the Laboratory of Center for Supervision and Certification of Food Crops and Horticulture Seeds, South Kalimantan Province, Banjarbaru City and used a one-factor CRD with w0 (+) (cans), w0 (-) (plastic sack), w1 (glass jars), w2 (plastic jars) and w3 (aluminum foil). The results of the study indicated that the use of impermeable storage containers had a significant effect on moisture content, germination, and maximum growth potential of rice seeds. The use of the best impermeable storage container for the moisture content of rice seeds in the storage period of 45 days after storage (das) was found in the w3 treatment (aluminum foil) of 11.63%, while the parameter of germination in the 15 das was 63.83%, the maximum growth potential in the storage period of 45 and 90 das was found in the w1 treatment (glass jar) of 73.50% and w0 (+) (cans) of 70.69%.
